EXPUNGEMENT OF CRIMINAL CONVICTIONS:
AN EMPIRICAL STUDY
J.J. Prescott and Sonja B. Starr
Laws permitting the expungement of criminal convictions are a key component of modern
criminal justice reform efforts and have been the subject of a recent upsurge in legislative
activity. This debate has been almost entirely devoid of evidence about the laws’ effects, in part
because the necessary data (such as sealed records themselves) have been unavailable. We were
able to obtain access to de-identified data that overcome that problem, and we use it to carry
out a comprehensive statewide study of expungement recipients and comparable nonrecipients
in Michigan. We offer three key sets of empirical findings. First, among those legally eligible
for expungement, just
6
.
5
% obtain it within five years of eligibility. Drawing on patterns in
our data as well as interviews with expungement lawyers, we point to reasons for this serious
“uptake gap.” Second, those who do obtain expungement have extremely low subsequent crime
rates, comparing favorably to the general population — a finding that defuses a common public-
safety objection to expungement laws. Third, those who obtain expungement experience a
sharp upturn in their wage and employment trajectories; on average, within one year, wages go
up by over
22
% versus the pre-expungement trajectory, an effect mostly driven by unemployed
people finding jobs and minimally employed people finding steadier or higher-paying work.

Taken together, these hurdles have been de-

and on a collective scale,
this phenomenon magnifies racial disparities in employment and other
outcomes due to disparities in the distribution of criminal records. For
all these reasons, a core part of this century’s emergent criminal justice
reform movement has been a search for effective policy levers to miti-
gate the reentry barriers faced by people with criminal records. This
effort is picking up steam in virtually every corner of the country, with two-

Perhaps the policy levers with the greatest theoretical potential to
improve reentry outcomes are laws that allow criminal conviction rec-
ords to be wholly expunged or, at least, sealed from public view. We
will refer to such laws collectively as “expungement laws,” and this pro-
cess as “expungement, although such shorthand elides some differ-
ences.
10
Expungement offers the possibility of sweeping aside a wide
range of legal and socioeconomic consequences at once; these laws typ-
ically authorize individuals to apply for jobs, housing, schools, and ben-
efits as though their convictions did not exist.
Today, a substantial majority of U.S. states provide some form of
expungement procedure for otherwise-valid adult convictions.
11
Many
states have recently adopted, or are presently considering, new expunge-
ment laws or expansions to existing ones.

The details vary by jurisdiction, and many advocates use various terms such as “expungement,”
“sealing,” and “set-aside” interchangeably. Typically, a true “expungement” legally eliminates the record
from the state’s perspective. “Sealing” maintains the record for some limited state purposes (for exam-
ple, law enforcement investigations of future crimes) but insulates it from public view.
11
Two useful online resources contain periodically updated collections of these laws; at our last
check, we found slightly different information at the two sites, but both include close to forty states
with some form of expungement law for valid, nonpardoned, and nonvacated adult criminal con-
victions. See

In 2018, Pennsylvania be-
came the first state to adopt a sweeping program of automatic expunge-
ment of adult criminal convictions — specifically, nonviolent
misdemeanors after ten crime-free years.
15
In 2019, Utah, New Jersey,
and California also enacted automatic expungement laws,
16
which are
more ambitious in some ways. For example, Utah has only a five-year
waiting period in some instances,
17
and California’s recent legislation
has even shorter waiting periods (none in some cases) and encompasses
minor felonies as well as misdemeanors, although the law only operates
prospectively.

Mexico are noteworthy as the first laws in those states to authorize sealing of adult criminal records.
Both states extend relief to most felonies, but they also require the applicant to pay a filing fee and
make the case for relief at a court hearing. (North Dakota courts may dispense with the hearing if

19
Other states may soon follow suit.
20
More typically, ex-
pungement laws require individuals to go through a judicial process to
apply for relief, usually giving judges the discretion to deny the petition.
Many states have stringent eligibility requirements as to crime type or
severity or the number of convictions on the individual’s record, and
many have waiting periods.
21
Despite the considerable legislative ferment and the excitement that
surrounds these “Clean Slate” initiatives in the civil rights and criminal
justice reform worlds, what has been missing from the debate is hard
evidence about the effects and true potential of conviction expungement
laws. Empirical studies in this area have been difficult to carry out.
Expunged criminal records are, obviously, not typically available to
study — and other relevant outcome data, such as wage information or
employment status, are also protected by privacy laws. While there are
many persuasive theoretical reasons to believe that expungement laws
will have large and important effects across many domains,
22
the dearth
of empirical evidence is a significant hindrance to reform and experi-
mentation. It leaves policymakers almost entirely in the dark.
In this Article, we present the results of an unprecedented statewide
study that overcomes existing limitations on research on expungement and
seeks to fill various policy-relevant gaps in our empirical knowledge. Pur-
suant to a data-sharing agreement with the State of Michigan, we were
able to obtain complete, de-identified criminal records from the
Michigan State Police (MSP) on all individuals who had received convic-
tion expungements (known as “set-asides” in Michigan) as of March 2014,
as well as full criminal history records for much larger comparison groups
of individuals with convictions that were not expunged. In addition, the
state matched these criminal histories with detailed wage and employment

data for the same individuals from the state’s unemployment insurance
program, sharing these data with us as well.
Michigan is an ideal setting in which to study expungement laws: it
is a large, diverse state with criminal justice challenges typical of the
United States today. Moreover, the version of Michigan’s expungement
law we study has many of the common features of a petition-based
record-clearing law, and it applies to a diverse set of records (e.g., vio-
lent/nonviolent, misdemeanor/felony), carries a fairly short waiting pe-
riod, has relatively straightforward eligibility rules, and went untouched
for more than two decades, allowing us to study results over time.
We use our unique data to investigate a number of interrelated em-
pirical questions, which can be grouped into three main areas of inquiry.
First, we examine the critical question of the “uptake rate”: the rate at
which those who are legally eligible for expungements actually receive
them.
23
We find that Michigan’s expungement uptake rate is discour-
agingly low; our best estimate is that only 6.5% of all eligible individuals
receive an expungement within five years of the date at which they first
qualify for one.
24
To better understand the uptake process, we examine
the characteristics of expungement recipients and their offenses and as-
sess whether some characteristics are predictive of uptake by eligible
individuals. We then use these data, plus interviews with Michigan ex-
pungement lawyers and advocates for people with criminal records, to
inform a discussion of why people might not apply for expungements
despite their potential benefits.
Second, we investigate expungement recipients’ subsequent criminal
offending.
25
We find very low rates of recidivism: just 7.1% of all expunge-
ment recipients are rearrested within five years of receiving their expunge-
ment (and only 2.6% are rearrested for violent offenses), while reconvic-
tion rates are even lower: 4.2% for any crime and only 0.6% for a violent
crime. Indeed, expungement recipients’ recidivism rates compare favor-
ably with those of the Michigan population as a whole.
26
We do not
claim that these low rates are necessarily because of expungements, al-
though there are several channels by which expungement receipt could
potentially contribute to lower recidivism risk. Another likely explana-
tion is that people who have limited criminal records and have gone at
least five years since their last conviction are simply very low risk to
begin with. This finding is consistent with the broader empirical liter-
ature on patterns of desistance from crime. Whatever the cause, the low

24
Although our data do not identify unsuccessful applicants, it is clear from follow-up inquiries with
the Michigan State Police that the low uptake rate can be primarily attributed to individuals’ failure to
apply, rather than to denials of applications by judges. See infra section II.C.6, pp. 2506210.

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2467
recidivism rates we observe help to defuse an otherwise potentially con-
vincing policy argument against expungement laws: that the public (in-
cluding employers and landlords) has a safety interest in knowing about
the prior records of those with whom they interact.
Third, we examine the employment consequences of criminal record
expungement.
27
After accounting for an individual’s prior employment
and wage history, as well as broader changes in the economy, we find
that expungement recipients experience considerable gains shortly after
receipt. Within one year, on average, an individual’s odds of being em-
ployed (earning any wages at all) increase by a factor of 1.13; their odds
of earning at least $100/week (a slightly more demanding employment
measure) increase by a factor of 1.23; and their reported quarterly wages
increase by a factor of 1.23 (and are sustained in subsequent years).
These results suggest that those with expunged records gain access to
more and better-paying jobs. To be sure, one has to be cautious about
drawing causal inferences here; it is very possible that some of the gains
come about because people choose to seek expungement at a time that
they are especially motivated to seek improvements in their economic
situation. Nonetheless, our data and other supporting evidence give us
some confidence that at least a large fraction of the improvement that
we observe stems from the clean record itself.
We provide background on expungement laws, existing relevant em-
pirical research, and our research setting (including our data and their
limitations) in Part I. We then present the three major components of
our work — our analyses of expungement uptake, the recidivism rates
among expungement recipients, and the relationship between expunge-
ment and subsequent employment outcomes — in Parts II, III, and IV,
respectively. In Part V, we respond to two potential objections to ex-
pungement, which might, if accurate, influence the policy takeaways of
our empirical results. In the Conclusion, we address policy implications
and consider future research possibilities.
Our findings tell a good news/bad news story: when expungement is
not automatic (and takes time, effort, and even money to apply), only a
very small share of the people eligible for relief actually apply for and
receive an expungement — but those who do experience clear improve-
ments in economic outcomes and pose little public-safety risk. Taken
together, these conclusions have a clear policy upshot: they support the
expansion of expungement availability, an easing of the procedural hur-
dles associated with seeking expungement, and, in particular, the emerg-
ing movement to make expungement occur automatically after a period
of time, rather than after an application process.

Several large bodies of scholarly research, as well as active policy
debates and commentary, inform and motivate our study. In section I.A,
we describe the many hurdles people with public criminal records face;
paring back these hurdles is the core policy motivation for expungement
laws and efforts to expand them. In section I.B, we add some further
detail to the Introduction’s description of the current legal and policy
landscape surrounding expungement. In section I.C, we discuss the very
limited empirical research that exists on expungement and identify the
key unanswered empirical questions that we seek to address. In section
I.D, we turn to our specific empirical setting, describing Michigan’s ex-
pungement law and the data that we use in our study.
A. The Economic and Legal Aftermath of a Criminal Conviction
The consequences of criminal convictions do not end when people
convicted of crimes complete their formal sentences. For many individ-
uals, punishments such as probation, fines, and even incarceration may
be dwarfed in importance by what comes next: exclusion from employ-
ment, obstacles to social integration, and a vast array of collateral legal
consequences that often last a lifetime.
28
A growing body of academic
research documents the scope, ubiquity, and size of these hurdles.
29
First, people with criminal records face serious employment barri-
ers — indeed, these barriers may exceed those facing any other disad-
vantaged group.
30
While many aspects of these individuals’ back-
grounds, as well as the interruptions to work and education experienced
by those who are incarcerated, may put them at greater risk of unem-
ployment than the general population,

seems to directly harm employment prospects.
32
Many employers report
that they take steps to avoid hiring individuals with records.
33
Their
motivations for doing so vary. A report prepared for the Department of
Labor has found that many employers are driven by “bias and stigma.”
34
Some believe that individuals with records cannot be trusted.
35
Others
fear a negligent-hiring lawsuit if an employee hired with a criminal rec-
ord commits a crime while on the job.
36
Experimental results confirm employers’ reluctance to hire individ-
uals with records. Devah Pager had matched pairs of testers, differing
only in criminal history, apply for a range of employment positions.
37
She found that applicants without records received more than twice as
many callbacks.
38
More recently, Amanda Agan and Sonja Starr sent
around 15,000 fictitious job applications paired by race to entry-level
jobs mainly in the restaurant and retail industries.

In a small study of expungement seekers in Chicago, “participants reported attempts to use face-to-

records, they were trustworthy and dependable. However, participants with both extensive and

2470 HARVARD LAW REVIEW [Vol. 133:2460
when employers asked about criminal history, the applicants without rec-
ords received 63% more callbacks, even though the records in question
were relatively minor.
40
Many employers, influenced by the national “Ban
the Box” movement and resulting law changes, have removed questions
about criminal history from initial job applications — but these employers
typically still conduct background checks before finalizing a hire.
41
A sur-
vey in 2012 reported that 87% of randomly sampled employers performed
criminal background checks on at least some employees; 69% performed
background checks on all employees.
42
This represented an expansion
from an earlier era, driven by the availability of easier and less costly
internet-based searches.
43
Almost all states place court records on the
internet,
44
and private companies, such as Westlaw and LexisNexis, also
market criminal history databases.
45
In addition to these employment consequences, criminal convictions
bring with them a wide range of other “collateral” legal consequences —
that is, consequences that are not part of the sentence but a function of
a wide array of civil laws. Licensing restrictions categorically exclude
previously convicted individuals from hundreds of professions.
46
These
individuals are often prohibited from receiving various social services,
including welfare and health benefits, public housing, and food

stamps.
47
Whole families can be evicted from public housing on the
basis of one member’s convictions.
48
Exclusion from housing renders
individuals with records homeless at high rates — for instance, in 1997,
the California Department of Corrections estimated that 10% of its pa-
rolees were homeless.
49
The specifics of these exclusions vary from state
to state, although some are encouraged or required by federal law.
50
They also vary based on crime type.
51
Because so many Americans have conviction records, these conse-
quences have a large aggregate impact. Repercussions include spillover
effects on family members never convicted of any crime; the Center for
American Progress estimates that almost half of U.S. children have a
parent with some form of criminal record (including arrests).
52
In addi-
tion, because criminal records are not equally distributed across the popu-
lation,
53
the effects of these collateral consequences are disproportionately
concentrated by race, gender, and poverty status, especially affecting black
men.
54
This concentration of criminal records may therefore be a signifi-
cant contributor to racial disparities in employment and other socioeco-
nomic outcomes.

2472 HARVARD LAW REVIEW [Vol. 133:2460
B. Sealing of Criminal Records: The Legal and Policy Landscape
More than two-thirds of states have adopted statutes that permit
adult criminal convictions to be sealed, set aside, or expunged.
55
These
laws generally require state agencies to ignore the affected individual’s
criminal record for most purposes other than law enforcement, thereby
lifting any statutory barriers to public employment, licensing, and ben-
efits. The laws also give an individual expungement recipient the legal
right to respond “no” when an employer or landlord asks if the applicant
has a criminal record.
56
In most states (including Michigan), sealed con-
victions remain available for law enforcement purposes, and for sen-
tencing in the event of a subsequent crime.
57
The specific eligibility requirements for criminal record expunge-
ment vary widely across jurisdictions. For example, some states’ laws
exclude certain classes of crimes, such as violent felonies.
58
Waiting pe-
riods also vary: In some states, at least for some categories of crime,
individuals can apply for expungement immediately after completing
their sentence (although evidence of rehabilitation must generally be
shown, which can be harder if little time has passed).
59
Other states, by
contrast, have minimum waiting periods ranging from one to twenty
years.
60
In some states (including Michigan), it is illegal for an employer
to discriminate on the basis of an expunged conviction if the employer
becomes aware of it.
61
The Collateral Consequences Resource Center
and the Clean Slate Clearinghouse provide comprehensive state-by-state
information on expungement laws.
62
Beyond adult conviction records, most states have other expunge-
ment policies covering at least some other types of criminal records, such

overturned or are subject to successful collateral attack.
63
Many also
have deferred-adjudication programs available for certain defendants
(for example, first-time drug crime defendants or youthful defendants),
in which no conviction is ever entered if the defendant completes certain
requirements.
64
These laws raise related empirical and policy questions,
and discussions about them might well be able to draw on our findings.
But we focus here on state laws that expunge otherwise-valid adult con-
victions that have become final; these policies have been expanding in
scope in recent years and are the subject of active political debates in
many states. Although supported by the American Bar Association,
65
and by advocacy groups such as the National Employment Law Project,
the Center for American Progress, and Community Legal Services,
66
they have also met with considerable political opposition, principally
from employers, who want access to information that they consider rel-
evant to hiring decisions.
67
The most recent wave of efforts to expand and improve expungement
laws — often referred to by advocates as the “Clean Slate” movement —
has focused to a large degree on the potential for automatic expungement
of certain criminal records after a certain period of time.
68
The ground-
breaking success in this area was the adoption of Pennsylvania’s Clean
Slate Act, which extends court-ordered criminal record sealing to encom-
pass a broader set of offenses and creates an automatic computerized pro-
cess for sealing certain eligible convictions: minor nonviolent misdemean-
ors after ten years without a subsequent conviction.

Bill received nearly unanimous legislative endorsement and was sup-
ported by an overwhelming majority of Pennsylvania residents.
70
Pennsylvania’s club became larger in 2019, when Utah, New Jersey,
and California enacted automatic expungement laws,
71
and similar reform
efforts are now underway in several other states,
72
including Michigan.
73
These newer laws have all been broader than Pennsylvania’s pioneering
statute along some dimensions. Of these laws, California’s is the most
ambitious, although (unlike the others) it does not apply retrospec-
tively.
74
The California law applies to all misdemeanors and to some
felonies resulting in probation,
75
and it imposes no lengthy waiting pe-
riod — indeed, none beyond sentence completion in some cases.
76
Utah’s
law, like Pennsylvania’s, is limited to nonviolent misdemeanors, but its
waiting periods for most crimes are only five to seven years depending

on the crime class.
77
New Jersey’s automatic expungement law has a
ten-year waiting period, but it allows some more serious crimes to be
automatically expunged; it delegates to a task force the development of
the process.
78
In addition, proposed federal legislation would require
automatic expungement one year after completing a sentence for mari-
juana offenses and certain other minor drug offenses.
79
Many states and local jurisdictions have also adopted other laws de-
signed to reduce barriers to employment of people with criminal records.
The most important category (along with expungement laws) are Ban-
the-Box laws and policies, which typically bar employers from asking
about records on initial job application forms and in initial interviews.
80
Thirty-five states (and the District of Columbia) and over 150 cities and
counties have passed Ban-the-Box laws governing public employers,
and a further thirteen states and eighteen cities and counties now extend
them to private employers.
81
In terms of the number of people affected,
Ban-the-Box laws are far more sweeping than typical expungement laws
because they apply to all criminal records and contain no eligibility re-
quirements. However, expungement, for those who do obtain it, offers
potentially far more significant relief from the consequences of criminal
convictions, cutting across different domains of life and, in effect, legally
erasing the conviction in question. In contrast, Ban-the-Box laws pri-
marily affect employer practices, and only change the timing of employ-
ers’ receipt of record-related information; they can still refuse to hire an
applicant after completing a background check.
82
Still, Clean Slate ad-
vocates typically see the two types of reforms as complementary, and
many advocacy organizations have pushed for both.
83
Some states have also adopted laws that substantially restrict employ-
ers’ use of criminal record information — for example, requiring that they

only rely on information that is job relevant.
84
These laws essentially rep-
licate guidance long given by the federal Equal Employment Opportunity
Commission (EEOC), which holds that overly sweeping bans on employ-
ees with records can amount to disparate impact racial or national origin
discrimination.
85
Unfortunately, courts have been reluctant to enforce
these restrictions.
86
Many employers throughout the country continue
to implement blanket exclusions of individuals with records, notwith-
standing EEOC’s guidance
87
— which, in any event, the Fifth Circuit
recently ruled is not enforceable.
88
These practices, and the difficulty of
eliminating them through other legal mechanisms, are among the moti-
vations for expungement laws.

Research on Expungement

questions surrounding expungement laws, despite the clear importance
of these inquiries to policymakers and the lives of millions of Americans.

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2477
absent comprehensive access to individual-level data on people whose
records have been expunged, and because those records are generally
unavailable, research has been stymied. Fortunately, by taking ad-
vantage of our unusual data access, we are able to examine several key
questions that have long remained unanswered.
First, there is essentially no research on the question of “uptake” in
the context of the expungement of convictions. The basic question re-
lates to the uptake rate: When people are legally eligible for expunge-
ment, how often do they actually apply for and receive it? Beyond this
question, we also seek to provide a richer picture of who receives re-
lief — what kinds of convictions they have, what types of sentences they
served, their demographics — and how their profiles compare to those
of the broader pool of eligible persons, that is, what factors predict ac-
tual receipt. Answering these questions can help us better understand
the problem of “uptake gaps” and can also inform the discussion of ex-
pungement’s effects. Given that the group that actually receives relief is
a highly selected one, in order to speculate as to the potential results of
extending expungement laws to a broader and possibly dissimilar popula-
tion, we need to understand that selection process.
Again, no published study addresses these questions with respect to
expungement laws.
89
However, in certain other post–conviction relief
contexts, there have been a few attempts to explore issues related to
uptake. The most comprehensive such effort is Colleen Chien’s research
estimating the uptake rates for several programs: President Obama’s
clemency initiative allowing certain federal inmates to apply for sen-
tence commutation; California’s Proposition 47, which allows some fel-
ony convictions to be reduced to misdemeanors; and California’s
Proposition 64, which legalized marijuana and provides various forms
of relief for those previously convicted on marijuana charges.
90
She
finds uptake rates of about 3%, 9%, and 3%, respectively (within a rel-
atively short time period, especially for the newer Proposition 64).
91
Chien also analyzes a sample of background-check data concerning

Very recently, Colleen Chien et al. released a short summary of preliminary findings from
their study of expungement uptake in Washington State. Colleen V. Chien et al., The Washington
State Second Chance Expungement Gap 1 (Feb. 28, 2020) (unpublished manuscript), https://
papers.ssrn.com/sol3/papers.cfm?abstract_id=3529777 [https://perma.cc/7AX6-PBE7]. The study
uses a random sample of cases to estimate how many cases are eligible for expungement in
Washington; comparison to reported statistics on the total number of expungements actually
granted implies that only about 3% of eligible individuals obtain expungement. See id. at 2, 5.

cases and track their outcomes. Instead, it compares publicly reported figures on the estimated
numbers of people eligible for relief and on the number of applications. See id.

“gig” jobseekers and finds evidence that many reports contain noncon-
viction records (for example, arrests not leading to convictions), at least
some of which should be clearable under state law.
92
Research by Chris-
topher Uggen and coauthors also uncovers large uptake gaps in voting
rights–restoration procedures for people disenfranchised due to felony
convictions.
93
Although none of these estimates focuses on the expunge-
ment of criminal convictions, they all suggest a general problem: when
criminal justice relief mechanisms require individuals to go through ap-
plication procedures, many people who might benefit from them will
not do so.
Second, we investigate subsequent recidivism outcomes for expunge-
ment recipients. We explore this particular outcome in order to address
the concern, often raised by opponents of record-sealing, that the public
has a safety interest in being able to identify people with records.
94
We are
unaware of any other empirical research on this question — a question we
are able to investigate because we have recipients’ full criminal records,
including post-expungement convictions.
95
Evidence on the recidivism
question is critical to addressing objections from those who fear endorsing
expungement policies because of the possibility that these policies could
hide or increase recidivism risk.
Third, we examine the employment consequences of expungement.
Although potential employment benefits are core to the policy case for

92
See id. (manuscript at 2535). The rates at which such nonconviction records appeared varied
substantially by state. See id. at 32 n.130. Note that because cleared records do not appear in back-
ground check data, Chien’s approach does not identify the number or share of eligible people who
do clear nonconviction records; rather, it simply shows that there are many who have not done so.
To estimate uptake rates for expungement among those eligible requires access to cleared records,
which researchers typically have not had. For background on nonconviction criminal records, their
use, and their regulation, see generally C

expungement laws, they have proven especially difficult to study be-
cause both expunged criminal records and wage and employment rec-
ords are typically confidential. The above-cited research showing that
criminal records impair employment opportunities provides a strong in-
tuitive reason to believe that expunging those records should have the
opposite effect. However, for several reasons, this intuition could prove
to be incorrect, and the magnitude of any effect is unknown. First,
many commentators have expressed concern that expungement may fail
to hide criminal history information from inquisitive employers — for
example, if news stories, mug shots, or other information about past of-
fenses can be easily found with a Google search or other digital means,
96
or if private criminal records databases do not effectively delete ex-
punged records.
97
Second, the waiting periods built into expungement
laws may undermine any potential benefits because these restrictions
mean that expungement cannot help during the critical period immedi-
ately after a conviction or during reentry.
98
Third, people with records
often also tend to face many other employment disadvantages besides
the record itself, potentially limiting the benefits of expungement.
99
To date, the most on-point research is a recent study by Jeffrey
Selbin, Justin McCrary, and Joshua Epstein, which tracks labor market
outcomes for 235 clients of a law clinic who pursued either expungement
or another form of relief (which allowed the reduction of felonies to mis-
demeanors).

As they acknowledge, however, their small sample size does
not “allow for precise estimation,”
102
and the study does not present sta-
tistical estimates with standard errors (which permit readers to evaluate
the degree of imprecision). In addition, their sample is not necessarily
representative of those who obtain expungement,
103
and their data do
not allow them to answer the additional questions we discuss above re-
garding uptake and recidivism outcomes. So while their study provides
a welcome start, its objectives were relatively modest. In contrast, we
analyze a large, statewide sample that includes all expungement recipi-
ents as well as a large comparison group of individuals eligible for ex-
pungement, and we are able to use these data to address a variety of
interrelated questions with statistical power.
D. Our Empirical Setting and Data
We conduct our research in Michigan. Michigan is a large, demo-
graphically diverse state; studying its population, therefore, is likely to
yield empirical findings that are broadly generalizable to the rest of the
United States. For example, Michigan’s 14.1% poverty rate is roughly
comparable with the 13.1% national poverty rate;
104
its $56,697 median
household income is also close to the U.S. median household income of
$61,937.
105
Michigan has roughly the same percentage of people who
identify as African American (13.8%) and white (78.3%)
106
as the coun-
try overall, although it has significantly smaller Hispanic and Asian
populations.
107
Michigans criminal justice system is also reflective of
national trends. Michigan’s property crime rates are now slightly lower
than the national average, but, for most of the study period, they hewed
closely to national crime rates; Michigan’s violent crime rates are a bit
higher than average.
108
Similarly, Michigan’s state prison population

increased at roughly the same rate as the overall state prison population
in the nation through the mid-2000s.
109
Today, Michigans incarceration
rate of 641 per 100,000 people is the 29th highest in the country, only
slightly lower than the national rate of 698 per 100,000.
110
In Michigan, expungement of criminal convictions is provided for by
a longstanding statute, M.C.L. 780.621. The law actually labels this
process a criminal record “set aside,” rather than using the more recog-
nizable term “expungement.” And indeed, as in most states, the
Michigan process does not entail a complete expungement of the record
(which is retained by the police for limited purposes mainly related to
criminal justice), but rather a sealing and an elimination of many of the
record’s legal consequences. However, to maintain consistency with the
terminology we adopt elsewhere in this Article, we will continue to use
the term “expungement” as a convenient and familiar shorthand.
M.C.L. 780.621 has been on the books since the 1960s,
111
although
expungements were very rare before a significant statutory change that
took effect in 1983.
112
It has undergone some recent amendments,
mostly expansions in its eligibility provisions.
113
Because of the time
range of our data, the most relevant version of the law is the one that
was in effect (with no material changes) from 1983 until mid-2011. Our
empirical analyses focus on people eligible under that law’s require-
ments, and on expungements granted before the law changed in 2011.
The fact that Michigan has had an expungement law for decades distin-
guishes it from the majority of other states,
114
and it makes the state a

(1981). Prior to the statute’s amendment, the limited availability of expungement in Michigan was
driven by the difficulties of accessing arrest records, see id. at 1394, and the narrowness of the
procedures available to seek expungement, see People v. Upshaw, 283 N.W.2d 778, 779 (Mich. Ct.
App. 1979). The statute was amended in 1982. See 1982 Mich. Pub. Acts 1887.

particularly useful subject for empirical study; Michigan’s long experi-
ence with record clearing can inform other states that have recently
adopted or are considering adopting similar policies. Cumulatively, tens
of thousands of people have received expungements under Michigan’s
law, and many received them long enough ago to allow us to observe
their post-expungement outcomes for a substantial period of time.
Michigan’s expungement law imposes a five-year waiting period,
115
which is in the middle of the range of the waiting periods that other
states’ statutes apply.
116
In the pre-2011 version, the five-year clock
began running at sentencing, unless the defendant served a term of in-
carceration after sentencing, in which case it ran from release.
117
Any
reconviction during this five-year period disqualified the individual
from an expungement.
118
Essentially, then, the law required five “clean”
years, excluding time behind bars. The statute covered (and still covers)
almost all types of crimes, including most violent felonies.
119
The prin-
cipal exceptions are traffic offenses, sex offenses that are subject to reg-
istration requirements, and the most serious class of felonies: those car-
rying potential life-imprisonment terms.
120
The wide range of crimes
otherwise covered is another advantage of Michigan’s law for research
purposes; it allows us to compare uptake rates and outcomes across
many important offense types and grades.

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2483
However, Michigan does impose stringent limitations on expunge-
ment eligibility based on the length of the individual’s record — that is,
the number of convictions (nonconviction records like arrests are not
relevant to eligibility).
121
While this has now been loosened slightly, in
the pre-2011 version, expungements were strictly limited to people with
exactly one conviction on a single charge.
122
Prior convictions, subse-
quent convictions, and simultaneous convictions — even multiple
charges stemming from the same incident — were all disqualifying. On
a policy level, this has incongruous results; for example, a person with a
single very serious felony may be eligible for an expungement, while a
person with two simultaneous misdemeanor counts arising from one in-
cident is not. However, the simple, bright-line nature of these eligibility
requirements offers advantages from a research perspective;
123
for ex-
ample, it makes it easier to code expungement eligibility and other var-
iables related to the nature of the criminal record.
For those meeting the eligibility requirements in Michigan, expunge-
ments are not automatic. Rather, the law requires the expungement
seeker to go through an elaborate application process, which we describe
in detail in section II.C. The court is not required to grant the requested
expungement — it “may” grant the request if doing so is warranted by
the applicant’s subsequent behavior and “consistent with the public wel-
fare.”
124
Still, grant rates are fairly high. Although our data do not
identify unsuccessful applications, the Michigan State Police (MSP),
which processes applications and also implements the expungements
once they are granted, shared figures for 2016 and 2017 that indicate
that approximately 75% of applications are successful.
125
To carry out our study, we entered into a data-sharing agreement with
multiple Michigan state agencies, which worked with us to develop a
merged and de-identified dataset. MSP provided comprehensive
Michigan criminal histories (RAP sheets) on almost every expunged crim-
inal conviction in Michigan history through March 2014,
126
amounting to

Email from Ted Kilvington, Court Reporting Coordinator, Mich. State Police, to Simmon
Kim, Research Assoc., Univ. of Mich. Empirical Legal Studies Ctr. (Feb. 22, 2019, 10:47 AM) (on
file with authors). Although the figures MSP provided cover more recent years than do the data
we use in our study, discussions with MSP and with expungement lawyers do not give us any reason
to believe there have been substantial changes in grant rates in the intervening years.
126
A small share of the most recent records was inadvertently dropped, as we discuss below.
2484 HARVARD LAW REVIEW [Vol. 133:2460
nearly 30,000 cases, plus a larger group of other criminal records meet-
ing requirements that we discuss below. These were linked to wage and
employment information for the same individuals from the state Unem-
ployment Insurance Agency and Workforce Development Agency.
Matching was based on Social Security numbers, so those without such
numbers are excluded from our analysis of wage data.
127
In addition to
the records for individuals who actually receive expungements, we ob-
tained records for a large group of people who were, at the time of their
convictions, potentially legally eligible for expungements in the future,
if they subsequently succeeded in meeting the five-clean-years require-
ment. This group consists of individuals with a first criminal offense
(occurring between 1999 and 2008) that was on a list of legally eligible
offense codes, which we developed using the expungement statute and
provided to the MSP for a data query.
128
Our data have other limitations. For our criminal record and em-
ployment outcome data, we lack information on out-of-state convictions
(affecting our coding of expungement eligibility and recidivism out-
comes) and out-of-state income (affecting our wage and employment
analysis). Our wage and employment information comes from the state
unemployment insurance system, which covers wage and salary employ-
ees quite comprehensively but misses the self-employed and individuals
employed “under the table.”
129
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
127
Michigan’s Department of Technology, Management and Budget carried out the matching
process, and then the department de-identified all records before it turned them over to us. In the
initial stages of our work on this project, in order to shape our records requests for MSP, we also
received and analyzed court records from Michigan’s Judicial Data Warehouse. However, because
of the incompleteness of these records, we did not include them in the ultimate data analysis.
128
Because MSP asked us to keep our request reasonable in size, we excluded from this list
certain common petty misdemeanors — such as dog-leash law and hunting and fishing violations
which are almost never expunged, even though they are legally eligible. We identified these as
among Michigan’s most common first offenses based on a preliminary analysis of court data from
the Judicial Data Warehouse, but these offenses are essentially not found at all in the complete
dataset on all expungements, perhaps suggesting that people do not bother to expunge records so
minor that they may impose no serious burdens. Some cases were also inadvertently excluded
because MSP formatted offense codes in inconsistent ways that did not match our list; these exclu-
sions seem substantively random. We also excluded minor-in-possession cases, which in Michigan were
(until the offense was decriminalized in 2016) often subject to a separate diversion process for youthful
individuals. We discuss the implication of these exclusions below, infra pp. 249293.
129
This means that our measured employment and wage levels will be biased downward relative
to total employment and wages. Although this is true to some degree both before and after ex-
pungement, it is possible that it is more true before expungement, if people with records are more
likely to seek under-the-table work. If so, we could overstate true wage gains. On the other hand,
there are reasons to focus on employment in the formal sector (as employment studies typically do).
There are distinct advantages to having formal labor market opportunities (for example, termina-
tion notice and other mandatory benefits). See Minhaj Mahmud et al., What Aspects of Formality
Do Workers Value? 3 (World Bank Grp., Knowledge and Strategy Team, Dev. Econ., Working Paper
No. 9108, 2020), http://documents.worldbank.org/curated/en/428331578944574540/
pdf/What-Aspects-of-Formality-Do-Workers-Value-Evidence-from-a-Choice-Experiment-in-
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2485
Our most serious data challenge involves missing records. The
state’s process for matching and de-identifying our criminal history and
employment outcomes data inadvertently dropped certain observa-
tions.
130
Fortunately, we were able to restore virtually all of the dropped
records that concern expungement recipients because we had already
received a complete version of that part of the dataset slightly earlier.
131
These drops only minimally affect our uptake analysis and should not
affect our employment analysis at all. However, the problem did lead us
to focus our primary recidivism outcome analysis on expungement recip-
ients alone, because the drops affect the accuracy of our recidivism
measures for nonrecipients.
132
Another data challenge relates to certain
missing dates in the criminal records data, a problem that requires us to
impute eligibility dates.
133
We believe this adds fairly minimal measure-
ment error. The imputation should not be far off, and should be correct
on average, so our resulting uptake estimates should not be biased, even
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Bangladesh.pdf [https://perma.cc/RM65-FDGY]. Indeed, to the extent that people do move from
under-the-table work to formal employment after receiving an expungement, it is presumably be-
cause the formal-sector option is more appealing. We discuss these issues as they pertain to our
analyses below.
130
Data patterns make clear that their procedure successfully identified duplicate records pro-
duced by overlapping data pulls by MSP but then mistakenly deleted both copies.
131
We were unable to restore some records for individuals who had not received expungements,
however. By the time we diagnosed the problem, our data-sharing agreement and grant period had
expired, and the state authorities informed us that they could not reconstruct the original dataset
for us or repeat the process. Through information from MSP, we were able to identify the number
of lost records (about 9% of the nonrecipients in the original data pull).
132
The dropped nonrecipient cases were individuals with at least two convictions, so omitting
them would have distorted our analysis. We requested data on people with certain kinds of first
convictions or second convictions within a ten-year period; people with first and second convictions
meeting these criteria were included as duplicates and then doubly dropped. The other set of du-
plicates dropped was the set of expungement recipients who also met the eligibility criteria for the
comparison group, but this was the set that we were able to restore.
133
When MSP effectuates an expungement, they change the disposition field in the record to
denote an expungement, but their data entry system does not have a separate field for the expunge-
ment date. Instead, MSP’s practice in most years was to change a field called “judgment date” to
the expungement date. This practice caused the information originally stored in the judgment date
field to be lost — specifically, the conviction date, which is what we use in most cases to calculate
the start date for the five-year expungement eligibility clock. Expungement eligibility in nonincar-
ceration cases runs from sentencing, which is usually a few weeks after the case disposition, Email

in the data. MSP informed us, however, that when they make their official determinations of ex-
pungement eligibility, they rely on the conviction date as a proxy for sentencing, so we do the same
here. See Email from Nick Romanov, IT Specialist, Mich. State Police, to J.J. Prescott, Professor
of Law, Univ. of Mich. Law Sch. (Nov. 7, 2018, 11:38 AM) (on file with authors). Because some of
our analyses (especially of uptake rates) require us to know both the expungement eligibility date
and the expungement grant date, we had to impute the lost conviction date based on the incident,
arrest, and charge dates.
2486 HARVARD LAW REVIEW [Vol. 133:2460
if we might get the date of eligibility wrong by a month or two for some
individual observations.
In a small subset of expungement cases, MSP changed the disposi-
tion code but did not change the judgment date field to the expungement
date, leaving no record of when the expungement occurred. These cases
are identifiable because the judgment date is too close to other key dates
in the case (for example, the arrest date) to be a plausible expungement
date given the required five-year waiting period. We eliminate these
cases from the recidivism and employment analyses, which require ex-
pungement dates; the lag time from other events in the case to expunge-
ment receipt is far too unpredictable to be imputed without introducing
significant measurement error. However, in our analyses of expunge-
ment uptake rates within certain periods of time, we cannot ignore these
cases or we would understate uptake, so instead we make assumptions
about their temporal distribution to estimate bounds on uptake rates.
Fortunately, the practical importance of this problem is small; there is
good reason to believe that most of these unknown-date expungements
occurred after June 2011, when we see a sudden drop in the number of
known-date expungements to virtually zero, reflecting a change in
MSP’s data-recording practice.
134
This date happens to coincide with
the substantive changes in the expungement law that (as we note above)
took place in 2011,
135
and the focus of our work is on expungements
taking place before that date anyway.

MSP confirmed that expungement dates are not recorded in their current data and that the
number of expungements granted has only increased since 2011. See Email from Ted Kilvington,
supra note 125 (stating that 2594 expungements were processed in 2017). Assuming expungement
frequency at least did not drop, we believe at least half the unknown-date expungements in the
earliest version of our complete expungement dataset (which ended in December 2012) must have
occurred between June 2011 and December 2012, which leaves at most 3000 occurring before then
(about 13% of the number of known-date expungements).

And a right
or opportunity that is too difficult for most people to exercise is effec-
tively empty. Accordingly, in this Part, we address several questions
surrounding expungement uptake (here defined as the successful receipt
of an expungement by someone who is eligible to receive one), which
have never previously been examined empirically.
138
In section A, we estimate the overall five-year expungement uptake
rate among those who are eligible for such relief. In section B, we turn
to the question of who successfully obtains expungements, presenting
descriptive statistics on recipients and regression analyses to assess
which individual and case characteristics predict expungement receipt.
We use these analyses in section C, along with qualitative insights pro-
vided by our interviews with expungement experts, to inform a discus-
sion of uptake hurdles and their implications.

2488 HARVARD LAW REVIEW [Vol. 133:2460
A. Estimating Uptake Rates
The first step in estimating expungement uptake rates is identifying
which cases are legally eligible for relief. In our context, the relevant
eligible pool is defined first by the parameters of the records query that
we asked MSP to implement, as detailed in section I.D, and second by
some further sample refinements that we carry out thereafter. These
sample parameters are: (1) The individual has a first criminal conviction
on a single criminal count.
139
(2) The crime of conviction matches an
offense code on a list of offenses eligible for expungement (known as a
“set-aside” in Michigan).
140
(3) Sentencing for the eligible count took
place between January 1999 and May 2001.
141
(4) The individual is not
subsequently convicted for any crime within five years of sentencing.
142
(5) The individual was not sentenced to incarceration on the eligible
offense.
143
And (6) the individual has no out-of-state driver’s license
listed anywhere in their MSP arrest record.
144
The five-year uptake rate is the percentage of this eligible group that
receives an expungement within five years of the eligibility date (that is,
within ten years of sentencing). We make two further assumptions in
order to calculate this uptake rate, which relate to the data problems we
identify above in section I.D. First, we assume the distribution of
unknown-date expungements in our sample, in terms of the time elapsed
since the case’s disposition, is roughly similar to the distribution of
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
139
This was a pre-2011 eligibility requirement. See supra notes 119, 122 and accompanying text.
As we describe below, we are able to screen only for prior offenses that took place in Michigan.
140
We are confident that our offense list only contains offenses that are in fact legally eligible for
expungement. However, as we explain in section I.D and discuss below, our list is not inclusive of
all eligible offenses.
141
Thus, expungement eligibility kicks in between January 2004 and May 2006 in our uptake
sample. Our sample contains the most recent set of cases for which we can still track outcomes for
five years after eligibility accrues. The main estimates we give are five-year uptake rates, and we
treat May 2011 as the end of our tracking period because two important changes occurred in June
2011: the eligibility rules changed (making more people eligible but also rendering some formerly
eligible persons ineligible), and MSP ceased to record expungement dates. For cases receiving ex-
pungements, because of MSP’s data recording practices, we impute the sentencing date.
142
This is also a legal requirement, and again we implement this filter based on Michigan data
alone. See supra p. 2482. Our eligible pool consists of people who became eligible after five years,
and we estimate expungement receipt rates within the next five years. Some members of this sample
could have lost eligibility at some point during the second five-year period due to a subsequent
conviction, although as we will see in the recidivism analysis in Part III, this happens rarely.
143
We focus on nonincarceration cases (which, as we will see below, constitute the large majority
of all expungement cases) because we have a more accurate measure of the start date of the eligi-
bility clock, which runs from sentencing. In incarceration cases, the eligibility start date is based
on release from incarceration, and because our data tell us only the sentence and not the actual
release date, we cannot account for possible early release or credit for time served pretrial.
144
In our data, driver’s license numbers have been removed, but for most observations we know
whether the individual had a driver’s license and, if so, the state that issued that license. We exclude
individuals with out-of-state driver’s licenses to reduce the likelihood of miscoding eligibility on
account of unobservable out-of-state convictions, but we retain those observations of individuals
who had no driver’s license identified in our data. This restriction eliminates about 4% of our
sample.
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2489
known-date expungements. We show below that our empirical conclu-
sions are robust to — that is, unaffected by — alternative assumptions
about the unknown-date distribution. Second, we assume that the miss-
ing nonexpunged records would not have met the criteria for inclusion
in this sample, and thus we do not adjust our estimate to account for
them. We believe this latter assumption is largely correct; dropped cases
all had at least two convictions within the years covered by the pool of
eligible cases given to us by MSP (19992008), few of which would meet
the five-year nonrecidivism criterion. To the extent this assumption is
mistaken, we understate the number of eligible cases and thus overesti-
mate the uptake rate (but likely not by much).
In Table 1, we present our main uptake estimate, which is discour-
agingly low. Of eligible individuals, only 6.5% receive expungements
within five years of becoming eligible. The remaining 93.5% includes
people who do not apply for expungements and those who have their
applications denied by a judge. However, as we note above, we learned
from MSP that in 2016 and 2017 combined, 74% of the expungement
applications MSP received were ultimately granted by courts. If we
assume that all of these applicants were legally eligible and that the
same ratio applies during the relevant time period for our estimate
(200411), 6.5% of those eligible for expungement receive one within
five years, another 2.3% have their applications denied, and 91.2% do
not apply during the first five years of eligibility. This extrapolation may
actually overstate the share of eligible people who apply for expungement,
because some denials are based on ineligibility.
145
In section C, we discuss reasons for this poor uptake. But, first, how
confident can we be in our principal estimate? In particular, given that
our sample is both overinclusive and underinclusive in some ways, is
our main uptake estimate for this sample a good proxy for expungement
uptake for the full eligible population during these years?
146
To inform
this question, the remaining rows of Table 1 present estimates based on
alternative assumptions and sample definitions.
Given that we find very
low uptake, we use the term “conservative” below to refer to assump-
tions that likely lead to an overestimation of uptake.
First, in Rows 2 and 3 of Table 1, we alter our timing assumption
for the unknown-date expungements. Ninety such cases appear in this
sample. Our initial assumption that their timing distribution mirrors
that of known-date expungements is conservative; there is a strong rea-
son to believe that these expungements occur disproportionately after

May 2011 (and therefore after the five-year period), when MSP stopped
changing the disposition dates in their records. We estimate bounds on
the possible scope of any error from this assumption. If we assume that
none of the unknown-date expungements occurred within five years of
eligibility, or, instead, we apply the most conservative assumption (that
they all occurred within five years), the resulting uptake estimates range
from only 5.7% to 6.7%. Because our original approach is conservative,
we assume that the correct uptake rate (if all other assumptions are
valid, that is) lies somewhere between 5.7% and 6.5%.
In Row 4, we add to the sample all cases involving incarceration of
up to one year, testing the effect of our exclusion of these observations.
We assume that these individuals served their full term of incarceration,
commencing on the date of sentencing. This assumption is also con-
servative because it ignores credit for time served and possible early
release; it thus errs on the late side in estimating the release date and
may include slightly more than five years of eligible time in the “five-
year uptake” estimate. After adding these cases to the sample, the up-
take rate drops to 5.4%, indicating that people who have been sentenced
to incarceration receive expungements at lower rates than other eligible
people. Thus, focusing on nonincarceration cases has the effect of in-
creasing our main uptake estimate. We do not include a five-year esti-
mate for those serving longer incarceration terms because we do not
have a sufficient follow-up period for most of these cases. However,
given the evidence that those who were incarcerated for relatively short
terms have a lower uptake rate, it seems likely that including individuals
with longer incarceration terms would only lower the rate further.
There are a few uncertainties about our uptake estimates that we
cannot address directly with our data. In particular, we have no records

Receipt of Expungement Within Five Years of Eligibility
Notes: The uptake sample (n=9103) consists of all individuals who have a first conviction on a single
criminal count in Michigan for an expungement-eligible crime with a sentencing date between
January 1999 and May 2001, and who were not incarcerated, were not reconvicted for any crime
within five years of sentencing, and did not have an out-of-state driver’s license. The sample for Row
4 (n=14,223) adds individuals who were incarcerated for their expungement-eligible offense for up to
one year and were released by May 2001.
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2491
of out-of-state or federal convictions, and so our “eligible” pool probably
includes some people who are not in fact eligible due to such convictions.
Our exclusion of people with out-of-state licenses mitigates this problem
but does not eliminate it, as people can move or commit crimes across
borders. Including ineligible cases in the eligible pool will produce an
underestimate of the uptake rate.
However, back-of-the-envelope calculations suggest that this prob-
lem is minor. The Census Bureau estimates that about 1.8% of lower-
income Midwestern households (the best available proxy for our sample)
move across state lines each year.
147
When we apply this rate of attrition
to our sample and extrapolate from the within-Michigan reconviction
patterns in our data, we deduce that we might fail to observe disquali-
fying reconvictions within five years for about 1% of the purportedly
eligible population.
148
We have a similar problem with potentially dis-
qualifying prior adult convictions for people who might have previously
lived elsewhere; this problem might be twice as large or so as that of
subsequent convictions, given the age distribution of our sample. It is
also possible for Michigan residents to commit crimes in other states,
although the great majority of crimes are committed very close to home;
we estimate that we might miss prior or subsequent cross-border con-
victions for perhaps another 7% or 8% of the sample.
149
All in all, miss-
ing out-of-state convictions likely cause us to overstate the size of the
eligible group by no more than 10% to 12%, and therefore to understate

or below. Id. If we use individual-level Census data instead, the interstate mobility estimate is
even lower — closer to 1.5%. See id.
148
To make this calculation, we assume that, per the state issuing their driver’s licenses, our
sample members were Michigan residents at the time of their convictions. The mobility estimate
implies that 7.3% of our sample would have moved away from Michigan after five years; for that
subgroup, we would miss on average the last 2.5 years of their criminal history. In our sample,
those who are not reconvicted within 2.5 years have a reconviction rate of 13% over the next 2.5
years; 13% times 7.3% is about 1%.
149
A large body of research finds that the average distance from an individual’s home to the
location of their crime is around one or two miles. See Michael Townsley & Aiden Sidebottom, All

RIMINOLOGY
897, 899900 (2010) (reviewing literature). One piece of
evidence that most crimes are committed in-state comes from our own data: among arrestees with
driver’s licenses, 96% are from Michigan. If we make the conservative assumption that all of the
balance are out-of-state residents (not just people with old licenses from a state of previous resi-
dence) and we assume conversely that about 96% of the recidivism committed by Michigan resi-
dents is in-state (not a necessary inference but a plausible approximation), it would imply that we
overlook reconvictions before five years in about 2.7% of our sample. We could also miss prior
convictions over a somewhat longer period (eleven years on average in our sample), some of which
would presumably have involved the same individuals.
2492 HARVARD LAW REVIEW [Vol. 133:2460
the uptake rate by less than one percentage point. Meanwhile, the fed-
eral conviction problem is likely small enough to be ignored because
federal convictions are extremely rare relative to state convictions.
150
In addition, our eligible pool of people with records is defined by the
parameters of the data query that MSP conducted on our behalf, which,
as we discuss in section I.D, is itself limited by the list of statutory of-
fense codes of the eligible crimes that we provided.
151
This source of
error likely cuts in the opposite direction, causing us to overestimate
uptake, because the largest category of legally eligible offenses that we
exclude from the list are petty offenses that we know are very common
first offenses in Michigan but are almost never expunged.
152
If we were
to include them, the uptake rate we estimate would be lower. Although
we inadvertently omit some additional observations due to irregular for-
matting of statutory codes, these exclusions are very likely effectively
random — that is, there is no reason to expect that the observations
with irregular formatting have either higher or lower uptake rates com-
pared to the rates of those we include in the sample.
Overall, we are confident that our main five-year uptake estimate of
6.5% is quite accurate for our sample, and it is in the ballpark of the
correct figure for the true population of eligible individuals in Michigan
during the years in question (200411); our best guess is that the true
uptake rate is probably lower. While the lack of data from out-of-state
and federal courts may bias our estimate downward, these biases cannot
be very large. Meanwhile, the assumptions we make about the missing
cases and the unknown expungement dates are designed to bias our up-
take estimate upward, and our constraints on the statutory code and the
exclusion of cases with incarceration terms almost surely do so as well. In
any event, the substantive story on uptake from our data is clear: very

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2493
few of those who are legally eligible for expungements receive them
within five years of becoming eligible. Indeed, even if the true five-year
rate were 10% — substantially higher than any version of our esti-
mate — it would still be strikingly low.
What about after five years? Unfortunately, we cannot directly esti-
mate a longer-term uptake rate because of the time range of our data on
the eligible-group sample. However, we do have data on the full uni-
verse of expungement recipients in Michigan up through 2011. Among
nonincarceration cases in this more inclusive sample, at the time of ex-
pungement receipt, 44% have an elapsed time since eligibility of more
than five years.
153
Assuming the same pattern holds for the cases in our
eligible sample, extrapolating from our main uptake estimate would pre-
dict a lifetime uptake rate of 11.6% for those not sentenced to incarcer-
ation.
154
Even this rate means that 88% of those eligible will never
secure relief — and those who receive expungements after many years
still forfeit many years of potential benefits.
B. Who Receives Expungements?
Only a small minority of people with records in Michigan are eligible
for expungements,
155
and only a small minority of this eligible popula-
tion in fact receives them. What distinguishes eligible individuals who
receive an expungement from those who do not? To develop insight into
possible reasons for the low uptake rate we identify and to develop hy-
potheses about policies that might increase it, we assess the characteris-
tics of the individuals who do receive expungements and their cases, and
we investigate which of those characteristics are usefully predictive of
an eligible person receiving an expungement.
In Table 2, we provide descriptive statistics of the relevant popula-
tions for this exercise. The statistics in Column 1 refer to the complete
population of all Michigan expungement recipients with known dates
prior to June 2011 (when the law changed). Columns 2 and 3 report
summary statistics for the main sample we use in our uptake-rate anal-
ysis on display in Table 1. Column 2 covers individuals within that
sample who did receive expungements within five years of becoming
eligible, and Column 3 covers the entire uptake sample (most of whom
did not receive expungements). Columns 2 and 3 can be usefully com-
pared to one another to shed light on how expungement recipients differ
from the broader eligible group. We note that some of the figures for

That is, we simply assume that the 6.5% share of the uptake sample who receive expunge-
ments within five years constitute 56% of those who will eventually receive expungements in their
lifetimes: 0.065/0.56=0.116.
155
Establishing the number of people with criminal records is notoriously difficult. Expungement
advocates consistently emphasized to us in interviews that very few people are actually eligible, which
is intuitive, given the strict limitations in terms of numbers of convictions (especially during the pre-
2011 period). See infra notes 204212 and accompanying text for further analysis.

sample (n=9103) in Column (3) consists of all individuals who have a first conviction on a single criminal count in
Michigan for an expungement-eligible crime with a sentencing date between January 1999 and May 2001, and
who were not incarcerated, were not reconvicted for any crime within five years of sentencing, and did not have
an out-of-state drivers license. The phrases “at eligibility and “before expungement” refer to the quarter in
which an individual first becomes eligible for expungement and the quarter before expungement, respectively.

expungement recipients look a little bit different in Columns 1 and 2;
this may arise from the various constraints on the Column 2 sample.
While expungement recipients have diverse personal and case char-
acteristics, some patterns stand out in the data. Relative to the criminal
convictions of the entire eligible pool (as shown in Column 3), convic-
tions that are actually expunged (as shown in Column 2) are much more
likely to be felonies; they are more likely to be property offenses, less
likely to be drug crimes, and roughly equally likely to be violent offenses.
Although expungements are not limited to minor crimes under the law
we study, most expungement recipients were not sentenced to incarcer-
ation for their expunged offense. In fact, among all expungement recipi-
ents historically, only 28.6% were incarcerated for any time at all, and only
1.9% were incarcerated for more than one year.
156
Finally, compared to all
eligible individuals, expungement recipients are less likely to be male and
more likely to be black.

2496 HARVARD LAW REVIEW [Vol. 133:2460
We report employment measures for both the quarter that the recip-
ient became eligible for the expungement and the quarter before actually
receiving it, which may offer suggestive evidence about whether em-
ployment changes influence the timing of expungement applications.
157
Here, we discern notable differences between the uptake sample and the
full sample of expungement recipients: in the former, employment rates
and wages are far lower just before expungement than they were at the
time of eligibility, whereas in the full sample employment is modestly
lower and average wages are actually higher. This difference may re-
flect the fact that the uptake sample is narrowly defined temporally, and
the five-year observation period for the uptake outcome (ending between
2009 and 2011 for all members of the sample) includes a major economic
crash;
158
for this reason, these numbers may not actually suggest any
broader relationship between employment setbacks and expungement
timing. We explore that potential relationship in Part IV.
As Column 1 in Table 2 shows, at the time of expungement receipt,
the median time elapsed since sentencing is 9.6 years.
159
In Figure 1,
we show more detail on the distribution of elapsed time, focusing on
those not sentenced to incarceration, all of whom would have become
eligible after five years had transpired. Figure 1 makes clear that there
is wide variation in the time lag between eligibility and expungement
receipt. On the one hand, the single year with by far the most expunge-
ments granted is the first year after the five-year waiting period expires
(that is, the sixth year since sentencing — labeled “Year 6”), roughly a
quarter of the total. This flurry of expungement activity suggests a pent-
up demand effect: some expungement recipients likely anticipate becom-
ing eligible ahead of time and apply more or less as soon as they can.
160
The monthly rate, not shown in the graph, peaks at four months after
the date of eligibility; this too is consistent with the pent-up demand
theory, since expungements typically take a few months to process.

The annual rate declines continuously thereafter (the last two bars in
the graph are taller only because they represent periods of five or more
years). Still, more than 44% of expungements take place after more than
five years of eligibility (year 11 or beyond), and almost 25% occur after
more than ten years of eligibility (year 16 or beyond).

Notes: The bars indicate the percentage of expungement recipients by county. The sample
consists of all individuals who have a first conviction on a single criminal count in
Michigan for an expungement-eligible crime with a sentencing date between January 1999
and May 2001, and who were not incarcerated, were not reconvicted for any crime within
five years of sentencing, and did not have an out-of-state driver’s license (n=9103).
In Figure 2, we present uptake rates by county for the six most pop-
ulous counties in Michigan (in descending order of population from the
left), and for Michigan’s other seventy-seven counties combined. The
figure reveals considerable local variation. Michigan’s largest counties
are primarily urban and suburban; five of the six (all but Kent) are in
Southeastern Michigan, within an hour of Detroit. Nevertheless,
Oakland County’s rate is more than triple that of Genesee County,
which it borders. All of the larger counties have higher uptake rates
than the rest of the state combined. However, by 2014, courts in every
county in Michigan had granted at least one expungement, and at least
ten had been granted in seventy-seven out of eighty-three counties (with
the remaining six all being among Michigan’s least populous).
Many of the individual and case characteristics listed in Table 2 are
correlated with one another, and with the county as well, which makes

inference from this table fraught. It could be, for instance, that the
higher uptake rate for black individuals can be entirely explained by
county-to-county variation; indeed, uptake rates are generally lower in
more rural, predominantly white Michigan counties. For this reason, in
Tabl e 3, we turn to regression analysis to test which individual and case
characteristics remain predictive of expungement uptake when we hold
other characteristics constant. We use logistic regression, a common ap-
proach for analyzing binary outcomes like expungement receipt.
162
We
present our results as odds ratios, which represent a multiplier of the
odds of the expungement occurring. An odds ratio greater than one
means that the variable is associated with increased odds of expunge-
ment receipt when other variables are fixed.
163
In Columns 1 through 3
of Table 3, we study the determinants of whether an individual receives
an expungement within five years of becoming eligible — the same out-
come we report in Table 1.
164
We estimate the following equation:
logit

𝑀𝑎𝑙𝑒

.
The outcome variable 𝐹𝑖𝑣𝑒𝑌𝑒𝑎𝑟𝑈𝑝𝑡𝑎𝑘𝑒 is an indicator for whether the
individual receives an expungement within five years of eligibility. 𝑀𝑎𝑙𝑒
and 𝐵𝑙𝑎𝑐𝑘 depict the individual’s reported gender and race; all nonblack
races are combined into one base category, which is 94% white.
𝐶𝑜𝑛𝑣𝐴𝑔𝑒 is the individual’s age in years at the time of the expungement-
eligible conviction. 𝐶𝑜𝑛𝑣𝑌𝑒𝑎𝑟 represents the year of that conviction.
𝐹𝑒𝑙𝑜𝑛𝑦 is an indicator for whether the crime of conviction is a felony,
and 𝐶𝑟𝑖𝑚𝑒𝑇𝑦𝑝𝑒 is a set of indicators for the type of crime: drug-related,
violent, and other, with property/economic crimes as the omitted refer-
ence category. Column 1 presents our baseline results. In Column 2
(and subsequent columns), we also control for county effects. In Column
3, we include individuals incarcerated for their crime for up to one year
and add an indicator for whether the individual was incarcerated.

162
However, linear (ordinary least squares) regression analysis produces substantively indistin-
guishable results when compared to the marginal effects from the logistic regressions.
163
Odds have a technical definition, and while they are not the same as probability, higher odds
do mean a higher probability. When probabilities are quite low (as they are here), the odds ratio is
a good rough approximation of the probability ratio. The odds that an event X (for example, an
expungement) occurs are equal to the probability that X occurs divided by the probability that X
does not occur. An odds ratio refers to the multiplier of these odds that applies with a one-unit
change in some explanatory variable.
164
For Columns 1 and 2 of Table 3, the sample is the same one we use for the main uptake
estimate in Table 1 (with constraints described in section II.A), and for Column 3, we add cases
with incarceration up to one year (the same sample we use in Table 1, Row 4). Our results are
robust to estimating Columns 1 through 3 on the same sample (in two different ways). The findings
in Column 4 are also unaffected by limiting the analysis to Column 5’s smaller sample. These
results are available upon request.
2500 HARVARD LAW REVIEW [Vol. 133:2460
The regression results in Column 1 show that, other things equal,
uptake rates are much higher among women and among people who
were relatively young at the time of their conviction. The impression
given in Table 2 of a higher uptake rate for black individuals completely
disappears in these regressions, implying that this racial difference is ac-
tually explained by other correlated characteristics. As for crime attri-
butes, the regressions all confirm that people with felony convictions
have, other things equal, more than twice the odds of receiving expunge-
ments. By contrast, people who have been incarcerated (even for short
periods) and people convicted of violent crimes have only about half the
odds of expungement receipt as otherwise similar individuals do; this pat-
tern is not apparent in the summary statistics in Table 2. A possible
theory for these results is that felony convictions make individuals much
more likely to apply (because felonies can trigger a wider range of col-
lateral consequences), but judges are less likely to grant expungements
in cases involving more serious or violent convictions.
165
Taken to-
gether, the pattern indicates that the people most likely to receive ex-
pungements are those with relatively minor felony convictions (espe-
cially women) — namely, felonies not resulting in jail time.
The regression results we present in Columns 4 and 5 also analyze
expungement receipt, but they replace the five-year uptake indicator
with a different outcome variable: whether an expungement is received
in any particular quarter. These analyses help us to understand the in-
fluences on expungement probability that vary over time — and in par-
ticular, to ask whether an individual’s immediate employment history
(such as a recent job loss) drives the decision to apply for an expunge-
ment. The dataset we use in these regressions has a panel structure,
meaning it contains separate observations for each quarter for each in-
dividual. The sample covers most of the people we include in the Col-
umn 3 analysis, depending on whether we have linked wage data for
them. The regression we estimate takes the following form:

The specifications underlying Columns 4 and 5 are similar to the
ones in the previous columns but also include variables that change over
time for a given individual. Column 4 includes whether an individual
was employed in the previous quarter (that is, whether any wages are
reported, which we discuss in greater detail in Part IV) and their re-
ported wages in the previous quarter, as well as the number of years
that have elapsed since the expungement-eligible conviction. We focus
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
165
See infra p. 2507.
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2501
on the role of the previous quarter in part because there is likely to be
at least a one-quarter lag between expungement application and receipt,
and we are interested in understanding the motivation for the applica-
tion. In addition, lagging this variable avoids the problem of reverse
causation: employment status and wages in the quarter of expungement
receipt could be affected by the expungement itself.
In Column 5, we focus on whether the individual recently experi-
enced an employment setback, which we proxy for with an indicator for
whether the individual’s wages had, in the quarter preceding the receipt
of the expungement, dropped by at least 20% compared to a year earlier
(denominated “Lost Wages” in Table 3). Our framework allows us to
assess the effects of wage loss on expungement receipt in a way that is
not confounded by the recession’s timing. The whole sample is affected
by the same economic trends, and the controls for year of conviction and
years since conviction (which together produce the calendar year) also
absorb those effects. The regression thus allows us to investigate whether,
among individuals subjected to the same broader economic conditions,
personal employment setbacks affect expungement probability.
We find, on the one hand, that being employed is a very strong pos-
itive predictor of expungement receipt in a particular quarter, increasing
the odds by a factor of 1.77 (Column 4). On the other hand, a recent
wage loss is an even stronger predictor, increasing the odds of expunge-
ment receipt by a factor of 2.27 (Column 5). Although these results are
in tension with each other, they each have plausible explanations: em-
ployed people may generally be more likely to have the resources, infor-
mation, and money to pursue an expungement; but people who have
experienced a recent employment setback may have more motivation to
pursue a new job. These results also help to inform our interpretation
of the wage and employment effects of expungement that we estimate
below; we refer back to these uptake findings in Part IV.
C. What Explains the Uptake Gap?
Given the many life disadvantages that come with a criminal record,
one might expect that most people who have records would jump at the
chance to leave their record behind. Yet strikingly few do so. Why?
Our quantitative data shed some light on this question but cannot really
answer it. To complement our data analysis, we sought out the insights
of experienced Michigan expungement lawyers and other advocates for
people with records, many of whom are actively involved with outreach
efforts (such as “expungement fairs”) that aim to encourage and facilitate
expungement applications.
166
We asked them for their perceptions of

the underlying mechanisms of limited uptake. Our discussions consist-
ently pointed to a set of likely explanations.
1
. Lack of Information. Every advocate we spoke to mentioned
this concern, and many thought it was the single most important uptake
barrier. Most people with records, even if they are eligible, lack the
information they need to pursue an expungement. As Tracey Brame,
who runs a law clinic that handles expungement cases, explained: “A lot
of people have absolutely no idea that they can do this.”
167
Many do
not know that the expungement law exists at all. Others may have a
vague idea that expungement is possible, but they do not know that they
are eligible or they are unfamiliar with what they need to do to pursue
one (or how to find out). Expungement law is complicated and not easy
for a layperson to grasp.
168
Many people do not understand their own
criminal records — for example, they may not know that their decision
to plead guilty to a traffic offense produced a criminal conviction. Sev-
eral advocates recounted running expungement fairs in which, even
though promotional materials identify the key eligibility requirements,
a substantial majority of those who turn up learn sometime after they
arrive that they are ineligible and walk out exasperated. It is certainly
plausible that there are just as many people who are eligible who assume
they are not. After all, the great majority of people with records are
ineligible for expungement, and in communities where many people
have records, to the extent that people know about expungement at all,
frustration with its stringent restrictions is common.
169
The shared im-
pression that “nobody is eligible” may be entrenched, including among
those who are actually eligible.
2
. Administrative Hassle and Time Constraints. Obtaining an
expungement requires a nontrivial amount of organization, effort, and
time. The process is drawn out and requires patience and ongoing re-
solve. A would-be applicant, after overcoming the basic informational
hurdles we describe above, must track down the official application
form, which is available on the website of the State Court

10. Mail a copy of the application packet to the correct prosecuting official
where the conviction occurred (county, city, or township) . . . .
11. On both copies of the application, fill in the Proof of Service on the back
of the form. After you fill out and sign the Proof of Service, mail or take
one of the remaining application packets with the completed Proof of
Service to the court. Keep the other copy for your records . . . .

It is easy to see how this list would be daunting and confusing to
potential applicants (and these steps do not end the process; a court
hearing follows, usually many weeks later).
172
Advocates confirm that
this is so; everyone we interviewed independently mentioned the admin-
istrative burdens facing applicants. As many elaborated, people with
records are usually struggling with a variety of life challenges. Taking
time away from work and childcare responsibilities to go to a police

station to be fingerprinted, to make several trips to a courthouse, to find
a notary, and to mail all these materials to the right addresses may be
simply impossible, or at least difficult enough to be strongly discourag-
ing.
173
This is especially so when prospective applicants do not live near
the court that convicted them, where their expungements must be pro-
cessed and the hearing must take place. And, finally, one experienced
expungement lawyer at a public interest organization pointed out that
many of her clients are already overwhelmed with paperwork, such as
the forms associated with receiving public benefits.
174
3
. Fees and Costs. Every expert we interviewed emphasized the
barriers erected by fees and other associated costs. The $50 expunge-
ment application fee cannot be waived, and it is not the only expense.
175
Michael Kiehne of Michigan Legal Help and Michigan Works estimated
that the total cost amounts to close to $100, including fingerprinting
($10–$20 at most local police stations), notary fees (up to $10), obtaining
a certified record of a conviction ($10–$12 if it is only one page), and
photocopies.
176
This does not include the costs of transportation and
possible loss of wages for time taken off work; Chioke Mose-Telesford
of Detroit’s Project Clean Slate emphasized that especially in a city with
poor public transit and low car ownership, the absence of transportation
options is a serious hurdle.
177
For applicants living in poverty, these accu-
mulated expenses are a serious financial impediment — consistent with
our finding that the unemployed are less likely to apply. In principle, one
could see the cost as an investment in future earnings; in Part IV, we
document average expected gains that would very quickly cover the
cost. But those without cash on hand may not have the liquidity or
ability to make such an investment or may be reluctant to do so when
the long-term benefits are speculative.

. Distrust and Fear of the Criminal Justice System. For many
potential expungement applicants, their prior experience with the crim-
inal justice system may well have been among the worst experiences of
their lives. According to several advocates, this often amplifies the
daunting nature of the expungement process; individuals with records,
at least five years removed from an earlier criminal justice ordeal, may

be strongly averse to returning to court or to a police station for any
reason.
178
This may be especially so if they expect the prosecutor or a
crime victim to come to court to contest an expungement petition, which
the law allows (and which sometimes happens).
179
In addition to fear
of the process itself, potential applicants may be pessimistic about the
likely outcome, even though most expungement applications are in fact
granted. As Kiehne explained:
Expungements are discretionary, and when you let people know that, they
tend to be pessimistic. We always try to tell people that many judges are
excited to grant these . . . . [But some] fear that it won’t work [for] them
an issue based on their past experience with the courts. . . . [S]o it is hard to
get this information through.
180
A potential applicant who fears that any request for an expungement
will be denied may be particularly reluctant to undertake the effort, cost,
and stress of pursuing record-clearing opportunities.
181
5
. Lack of Access to Counsel. Some of the obstacles above could be
overcome or rendered less discouraging with legal assistance. Although
expungement applications can be filed pro se, the process is far less diffi-
cult to navigate for an experienced attorney.
182
Yet, too often, none are
available. Criminal defense lawyers are typically long since out of touch
with their former clients by the time they become eligible for expunge-
ment, and most of the time defense lawyers do not advise their clients

A small survey of recipients of record clearance in California described respondents’ past

ences were ultimately far more positive. See id. (noting that, given their past bad experiences,
respondents were often surprised by the respect they received from judges and district attorneys
during the clearance process).

about the possible prospect of an expungement five years in advance,
either. Paid attorneys are out of reach for most people with records.
183
And legal aid or pro bono attorneys with time on their hands are too
rare. Although there have been some recent improvements on this front
(which we discuss below), one legal aid lawyer with extensive expunge-
ment experience explained to us that many legal aid organizations are
simply overwhelmed with the many other needs they are asked to serve,
which makes it “hard to ask them to take on a whole new area.”
184

. Insufficient Motivation to Pursue Expungement. Notwith-
standing the various hardships that tend to be associated with having
a criminal record, not everybody with a record is affected by it in the
same way. Virtually everyone with a criminal record would presumably
prefer not to have it, but not everybody necessarily experiences the re-
cord as a burden sufficient to motivate them to take on the investment
of time, money, and energy that an expungement demands. This may
be especially true for people with minor convictions — a theory sup-
ported by our finding that those with misdemeanors are less than half
as likely to obtain expungements as those with felonies are. It seems
implausible that judges would on average be less willing to grant ex-
pungements for misdemeanors, so the only credible explanation is that
people with misdemeanors are less likely to apply. This is intuitively
sensible. While misdemeanor records can certainly have nontrivial conse-
quences,
185
many collateral legal consequences apply only to felonies,
186
and some employment applications ask about only felony records.
187
It is
not surprising that those with felony records appear to be particularly
motivated to pursue expungement relief. In addition, motivation may
affect the timing of expungements; as Tracey Brame explained: “A lot of
people don’t prioritize it until [the conviction] is a problem,” such as
when they are trying to pursue an occupational license.

policies — including the common requirement that eligible individuals
file a petition — are embedded in a larger criminal justice context, one
rife with access-to-justice and punishment disparities along economic
and racial dimensions.
189
To those familiar with that context, the uptake
gap, while stark, may actually be unsurprising. The gap aligns with
Sarah Brayne’s finding that people involved in the criminal justice sys-
tem are more likely to engage in “system avoidance” by self-selecting
away from institutions that keep formal records or carry the mantle of
government because they fear the prospect of adverse state surveil-
lance.
190
The burdens of seemingly unrelated policies, therefore, may
help us understand the failure of uptake with respect to expungement.
Nevertheless, addressing the immediate barriers to uptake we de-
scribe above is critical, and various organizations have taken important
steps to improve matters. Over the past fifteen years, as the challenges
facing people with records have drawn more attention nationally and in
Michigan,
191
significant efforts in Michigan to increase support for peo-
ple seeking expungement have sprouted. The City of Detroit, for exam-
ple, recently adopted an initiative called Project Clean Slate to support
expungement activity,
192
and Michigan Works, a statewide workforce
development program, has become increasingly involved in the issue.
193
Michigan Legal Help, a nonprofit that provides do-it-yourself tools to
pro se litigants, has developed an online tool that allows applicants to
assess their eligibility and to fill out the application form, although they
must still go through the various steps to file it.
194
Many of these organizations have sponsored expungement fairs,
which have become perhaps the central outreach tool in this space.

Expungement fairs are designed at a minimum to provide information,
and many also provide concrete assistance: applicants have been encour-
aged to fill out applications on site, and some fairs have had sheriffs
present to do the fingerprinting, as well as notaries.
196
Depending on
the sponsoring organization’s funding, these fairs have sometimes been
able to defray the costs for applicants — for example, by offering fin-
gerprinting for free or paying for the certified record of conviction.
197
Expungement fairs in Detroit have reportedly been quite large, some
perhaps close to a thousand participants, although most attendees have
proven to be ineligible.
198
Fairs elsewhere in the state have generally
not had anywhere close to this kind of attendance.
199
Miriam Aukerman, who worked on expungement cases at Western
Michigan Legal Aid until 2010, told us:
When I started doing this work back in 2003 or 2004, nobody was doing it.
People didn’t think it was important. When I left in 2010, it was a thing.
Legal services offices had started doing it; there were self-help packets avail-
able . . . . Expungement fairs were starting to happen. Advocacy organi-
zations started spreading the word.
200
Aukerman’s recollection is borne out by data. In 2010, the last full year
for which we have complete data, the number of known-date expunge-
ments granted in Michigan was 2044, which is 67% higher than the
number in 2004 (1224). MSP reported to us that 2594 expungements
were granted in 2017; this number (although down slightly from 2016)

Telephone Interview with Miriam Aukerman, supra note 166.
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2509
represents another 27% growth since 2010.
201
These changes suggest
that efforts to help people surmount the various barriers to access ex-
pungement opportunities can successfully encourage applications.
That said, one should not be too sanguine; even if uptake doubled
from what we measure (for five-year periods ending between 2009 and
2011), it would still be only 13%. Expungement lawyers articulated to
us the frustration that many of their clients feel with the process, even
with legal help.
202
Rather than expect a massive influx of aid to help
people navigate the process, we should recognize that substantially clos-
ing the uptake gap will require legal changes to simplify that process.
We return to this point in the Conclusion.
Finally, it bears noting that, although our interviews focused mainly
on the problem of low uptake among eligible individuals, every advocate
we spoke to also stressed the stringency of the eligibility requirements,
which in each of their views exclude a great many worthy candidates.
203
Reforms in 2011 and 2015 slightly softened the requirements regarding
the allowable number of convictions,
204
but they are still strict and in
many ways quite arbitrary. Today, in Michigan, anyone with two felony
convictions is still excluded, even if they are low-level felonies and even
if they are two counts arising from the same incident.
205
Inexplicably,
people with three misdemeanors cannot seek expungements at all, even
though people with one felony plus two misdemeanors can seek to ex-
punge the felony.
206
Traffic misdemeanors cannot be expunged them-
selves but nevertheless count toward the limit and thus may disqualify an
individual from expunging another conviction.
207
These offenses are very
common in Michigan, accounting for more than half of all misdemeanor

convictions.
208
Petty misdemeanors, including violations of hunting and
fishing laws and dog-leash laws, likewise count toward the limit.
209
In
addition, the waiting period now runs five years from the completion of
all components of the sentence, which means that people with lengthy
probation or parole terms might actually have to wait out eight or ten
recidivism-free years in the community, not just five years as was re-
quired under Michigan’s old law.
210
All of these restrictions mean that the low uptake rate we estimate
is even starker when viewed in context: it is a very small fraction of a
very small fraction. For the past decade about 2000 expungements per
year have been granted in Michigan. Meanwhile, each year the Michigan
state courts add about 300,000 new criminal convictions.
211
On balance,
the population of people living with criminal records is continuing to
grow quickly; the existing expungement regime is like a bucket remov-
ing water from an ever-rising ocean.

ECIDIVISM
O
UTCOMES
Petition-based expungement is not very common — but what happens
when it does occur? Are there significant public-safety costs to granting
record-clearing relief? For example, does expungement increase the risk
of recidivism or conceal other substantial dangers from the public? Pub-
lic-safety concerns underlie the most common objections to expunge-
ment laws, the idea being that the public — especially people with par-
ticular interests at stake, such as employers and landlords — have a
right to know when people have criminal records because of their
heightened risk of committing future crimes.

us that it is common for her clients to believe they are eligible for an expungement because they do

sunnier picture. In section A, we estimate recidivism rates for expunge-
ment recipients, finding that reoffending is strikingly rare. In section B,
we consider the interpretation and policy implications of our findings.
In this discussion, we rely mainly on other criminological research for
guidance; as we explain below, the nature of the law and our data make
it difficult to directly assess the causal effect of receiving an expunge-
ment on criminal behavior.
A. Recidivism Among Expungement Recipients
In Table 4, we report two-year and five-year rearrest and reconvic-
tion rates for expungement recipients, starting from the date of receipt
of the expungement.
214
We analyze the criminal histories of the full
universe of individuals receiving expungements up through the begin-
ning of December 2010.
215
Most of the data concerns we raise with
regard to the “eligible” sample of individuals with records that we ana-
lyze in Part II do not arise here.
216
Our only significant data limitation

(stating that employers want access to criminal records so they can “protect employees, customers,

Recidivism rates are a complicated concept, see generally M

(1984), and one of the important questions in constructing estimates is the length of time over which
to consider an individual “at risk” of reoffending. At least within the domain of government statis-
tics, there is no real consensus on the appropriate at-risk period. See Bill Montgomery, We Have

https://www.bjs.gov/content/pub/pdf/18upr9yfup0514.pdf [https://perma.cc/YT9K-MAQ9]. Longer
time spans are generally more beneficial for studying patterns of recidivism and their attributes.
See id. We are readily able to offer a longer-term measure, too, because our data cover a more
extensive span than many other researchers have been able to observe. We opt to include both two-
and five-year measures to provide both points of comparison.
215
We rely for this analysis on an MSP criminal history dataset that ends on December 6, 2012.
To allow a sufficient follow-up period, our analysis sample accordingly includes nearly all individ-
uals receiving expungements in Michigan with known dates up through December 6, 2010 (for the
two-year rates), and December 6, 2007 (for the five-year rates). The only individuals we drop are
232 people identified in the data as having out-of-state driver’s licenses, to reduce any bias that
might result from unobserved out-of-state recidivism. The resulting numbers of observations for
our analysis are 20,955 for the two-year sample and 15,256 for the five-year sample.
216
The rates we report are not really “estimates” for these populations; there is no sampling error
in the results that we report for pre-2011 Michigan expungement recipients. We need not worry
about the representativeness of the sample in thinking about how expungement recipients fared in
Michigan during our study period. However, our calculations are “estimates” if we think of past
expungement recipients as a “sample” that is representative of future expungement recipients (or,

potentially, expungement recipients from other jurisdictions) about whom we wish to make predic-
tions. Accordingly, we include standard errors in Table 4, in parentheses; these show that our
estimates (if understood as such) are in any event quite precise.

Notes: Rearrest and reconviction data come from Michigan State Police criminal history files. The full sample consists of
all individuals with no record of an out-of-state driver’s license who receive a known-date expungement in Michigan
through December 6, 2010, for two-year rates and through December 6, 2007, for five-year rates. In Panel B, all rearrest
and reconviction rates are “overall” rates — that is, they count any new criminal arrest or conviction — except for Row 8,
which shows only the rearrest and reconviction rates for violent offenses. Standard errors are reported in parentheses.
Subsample sizes are available from the authors upon request.

is our inability to observe out-of-state and federal arrests and convic-
tions,
217
which may mean that we slightly underestimate true recidivism
rates. We do not believe this omission has a large effect, however, for
reasons we already discuss in detail in Part II: federal arrests and con-
victions are rare, and interstate moves and interstate travel to commit
crimes are not common either.
218
In Row 1 of Table 4, Panel A, we report the overall two-year and
five-year rearrest and reconviction rates, while in the remaining rows
we give specific rates for certain types of crime that may be of particular
public and policy concern: violent offenses and felony offenses.
219
All of
these rates show a consistent pattern: recidivism among expungement
recipients is low.
220
Overall, 3.4% are rearrested and 1.8% are recon-
victed for crimes within two years; 7.1% are rearrested and 4.2% are
reconvicted within five years. The numbers are even lower when we
focus specifically on the types of crimes that worry people most. For
example, within five years, only 2.6% of expungement recipients are
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
217
See supra notes 147150 and accompanying text.
218
Applying the assumptions we use in Part II that 1.8% of individuals move per year and 4%
of crime is committed across state borders, we expect we might be missing about 56% of the re-
arrests and reconvictions for our two-year outcome period and perhaps 78% in the five-year period
(when people have had more time to move). See supra notes 147150 and accompanying text.
Given the very low recidivism rates we report in Table 4, the effect of this problem is negligible in
percentage-point terms. Another useful source is a 2005 study from the Bureau of Justice Statistics,
which finds nontrivial rates of out-of-state recidivism over the course of five years (whether due to
cross-border crime or individuals changing their state of residence). See M

pdf [https://perma.cc/J2BP-WTKN]. But still, even that out-of-state recidivism rate (10.9%) is only
about one-seventh of the overall recidivism rate (75.4%) observed over the same period. Id. at 7
8. If we were to apply that same ratio here, our estimated recidivism rates would understate the
true rate by much less than a percentage point. Moreover, Michigan residents almost surely engage
in fewer cross-border crimes than residents in many states, simply because Michigan is surrounded
on most sides by water and has no interstate metropolitan areas.
219
Felonies are identified as such in the MSP records we use in our analysis; we classify an
offense as violent if it involves the use or threat of force according to its statutory definition. Stat-
utorily, a felony in Michigan is defined as an offense for which a person convicted of the charge
may be punished by death or imprisonment. See M
ICH
. C
OMP
. L
AWS
§ 750.7 (2020). Violent
offenses are a subset of both felonies and misdemeanors.
220
Recidivism risk varies by type of initial crime, age, poverty, and many other factors, but in
general, recidivism rates below 10% are relatively low. For example, in a recent multistate study
of prisoners released in 2005, over 60% are rearrested within two years, and 77% are rearrested
within five years. See A
LPER

(to more closely match our data), these numbers are 54.4% and 66.1%, respectively. See id. at 4

rearrested and 0.6% are reconvicted for violent crimes; 2.7% are rearrested
and 1% are reconvicted for felonies.
We emphasize that these rates are much lower than those found in
most studies of criminal recidivism.
221
Indeed, our statistics suggest that
expungement recipients pose a lower crime risk than the general popu-
lation of Michigan as a whole. Although no general-population data are
available that directly parallel the figures in Table 4, the state does re-
port annual arrest figures. For comparison purposes, in the two-year
period from 200910, Michigan police made about 6.6 arrests per 100
adults in the population.
222
In contrast, using cases from approximately
the same time period, we calculate only 4.7 arrests per 100 expungement
recipients within two years of their having received an expungement.
223
This comparison is particularly striking given that expungement recipi-
ents (like people with criminal records generally) tend to have other

We calculate this number for the cohort of those receiving criminal-record expungements be-
tween December 2006 and December 2010, running for two years from each individual’s expunge-
ment date and excluding those individuals known to have out-of-state licenses; this is the most
recent complete expungement-receiving cohort for which we have two years of subsequent criminal
history data. Total arrests per capita over two years are higher than the two-year arrest rates for
the same population (like those we report in Table 4) because some people are arrested more than
once. See Alexi Jones & Wendy Sawyer, Arrest, Release, Repeat: How Police and Jails Are Misused

the best metric to use for this comparison. We do not have a similarly authoritative source for the
number of convictions statewide. However, we can gain some insight into individuals who are
arrested multiple times from the Prison Policy Initiative: “Using nationally representative data from
the National Survey on Drug Use and Health (NSDUH), we find that at least 4.9 million individuals
were arrested and booked in 2017. Of those 4.9 million individuals, 3.5 million were arrested only
once in 2017; 930,000 were arrested twice; and 430,000 were arrested three or more times.” Jones
& Sawyer, supra.

characteristics that are generally associated with higher crime risk —
for example, they are more likely to be male and poor than the general
population is. In fact, if we compare expungement recipients to subsets
of the general population that look more like them in terms of observa-
ble characteristics such as age and gender, the comparison is even more
favorable to expungement recipients.
224
In Panel B of Table 4, we replicate the main results from Panel A,
Row 1 (overall arrest and reconviction rates) for subsets of the expunge-
ment population of particular interest. In Row 1, we examine individ-
uals who receive their expungements early, in their first year of eligibility
(that is, by the end of the sixth year since sentencing or release). The
waiting period for expungements in Michigan is five years, but the ac-
tual median elapsed time before receipt is nearly ten years after sentenc-
ing or release.
225
Because recidivism risk declines over time, this delay
should be expected to reduce expungement recipients’ recidivism
rates.
226
But policymakers might understandably wonder what would
happen if people did not wait those extra years — which would be the
consequence of a policy that made expungements automatic after five
years.
227
Row 1s estimate in Table 4.B is designed to inform the ques-
tion whether five years is enough of a waiting period — and what we
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
224
These calculations are available upon request. Age and gender are two of the characteristics that
most strongly predict arrest rates, so it is helpful to begin by considering their role. One might expect
that expungement recipients’ low recidivism risk could be explained by the fact that, by the time they
qualify for an expungement, they have already “aged out” of crime. But while this may sometimes be
true (and indeed there are few very young adults who obtain expungements), the overall age distribution
of expungement recipients is similar to, and actually a bit younger than, the general adult population;
a majority are still in their twenties and thirties, ages when arrest rates are still higher than average.

while, a majority of expungement recipients are male, see supra tbl.2, and males have higher arrest
rates, see S

, supra, at 2. If one reweights the general population arrest rates so as to mirror the
expungement-recipient pool in terms of its age and sex distribution, the projected general-population
rate becomes even higher: about 7.6 arrests per 100 people in each two-year period (compared, again,
to 4.7 for expungement recipients). General-population arrest data are not available broken down by
many other characteristics, but we can be fairly certain that populations that are comparable to ex-
pungement recipients across other demographic and socioeconomic dimensions would have even higher
arrest rates, since expungement recipients tend to be disadvantaged in various ways, as we explain in
Part II. See supra section II.B, pp. 24932501.

find in our data suggests that it is. Recidivism rates in all columns are
only very slightly higher than the main-sample numbers, indicating that
this subgroup remains low risk relative to the general public.
Meanwhile, Row 2 in Table 4.B shows rearrest rates for people who
receive expungements in the eleventh or twelfth year after sentencing or
release — a good proxy for the effect of providing for expungements
after ten clean years, as Pennsylvania’s new law does automatically for
minor offenses.
228
These recidivism rates are even lower than average
expungement-recipient rates (unsurprisingly, given the long clean rec-
ords of these individuals). All in all, though, the differences among these
various cohorts are quite small, suggesting that eligibility waiting-period
differences might not matter very much in terms of fostering lower post-
expungement recidivism rates.
In Rows 3 and 4 of Table 4.B, we show recidivism numbers for those
whose expungement conviction was a felony and a misdemeanor, respec-
tively. Recidivism rates are low for both groups, although slightly higher
for the felony group. In Rows 5 and 6 respectively, we compare the
behavior of expungement recipients who did and did not serve any time
behind bars, according to MSP records. One might expect recidivism
rates for the formerly incarcerated to be higher for two reasons: they
have more serious prior convictions,
229
and they may face additional
socioeconomic disadvantages arising from their period of incarcera-
tion.

Finally, in Rows 7 and 8 of Table 4.B, we present recidivism numbers
for people who have had violent-offense convictions expunged. In Row
7, we demonstrate that the overall rearrest and reconviction numbers
for this subsample are slightly higher than the average for the entire
sample, although still quite low. In Row 8, we report the rearrest and
reconviction numbers for new violent crimes alone (as we did in Table
4.A, Row 2). This comparison addresses the specific fear that employers,
landlords, and policymakers might have about people with a past vio-
lent offense: that they will commit another violent crime.

Although
the rates of violent reoffense that we calculate are very slightly higher
in the subsample with violent crime convictions, they are still extremely
low in absolute terms.

Only 0.3% of those who have had a violent
offense expunged are reconvicted of another violent offense within two
years, and only 0.8% within five years.

2518 HARVARD LAW REVIEW [Vol. 133:2460
B. Interpretation and Implications
Our recidivism analysis should, at the very least, dispel any notion
that individuals who receive expungements under Michigan’s law pose
any particular risk of reoffending. And the same is likely to be true in
other states considering similar record-clearing laws. Employers and
landlords should rest assured that petition-based expungement laws
with comparable requirements and waiting periods are unlikely to deny
them access to information that they need to protect themselves or their
employees, customers, or tenants.
But what are the broader implications of this analysis for expunge-
ment policy, both in Michigan and beyond? In particular, do the data
allow us to say anything about the effects of broadening the availability
of expungement — either procedurally (for example, by rendering it au-
tomatic) or substantively (by loosening eligibility requirements)? Ex-
pungement recipients are, again, an unrepresentative sample of individ-
uals with criminal records. Primarily, they are self-selected — they had
the motivation to apply for expungement, the belief that their case could
be convincing to a judge, and the energy, money, and organizational
skills to complete the application process.
234
They are also filtered by
judges’ discretion, and judges presumably look for candidates who seem
to be at low risk of committing future crime. So we cannot assume that
subsequent crime rates for people who are not selected in the same way
would be as low. And if they were not as low, would the public-safety
objection then become legitimate?
To address these questions, we must consider two separate influences
on post-expungement recidivism rates. The first is baseline risk: the risk
of recidivism, absent expungement, of those same individuals.
235
The
second is the causal effect of expungement on these individuals’ subse-
quent criminal behavior.
236
Either or both could contribute to the low
recidivism rates that we see in our expungement sample — that is, re-
cipients could have been low risk regardless and/or the expungement of
their record could have lowered their risk. Unfortunately, we do not
have a good empirical technique for using our data to disentangle these
two theories. This is mainly because of the key legal requirement for

that many potential recipients do not apply for record-clearing relief because of various institu-
tional, psychological, and practical barriers).

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2519
expungement: nonrecidivism. Recidivism rates are by definition zero
before people become eligible for expungement and before they receive
one, which means that a study with a “pre-post” design cannot mean-
ingfully evaluate expungements effects on recidivism.
Accordingly, to inform a discussion of what seems most likely to ex-
plain the low post-expungement recidivism risk we estimate, we turn
for guidance to the criminological literature more broadly. Scholarship
in this area provides strong support for both explanations for our em-
pirical results. Expungement recipients probably have low baseline re-
cidivism risk at the time they receive an expungement, and the receipt
of an expungement probably lowers this risk further.
As to baseline risk, first, a key finding of the relevant research is that
most people who commit crimes do not continue to do so forever. Within
the large criminological literature on recidivism and patterns of de-
sistance from crime, a small but important subset of work focuses on
the extent to which older criminal records remain usefully predictive of
future offending.
237
In particular, it asks: When people have remained
crime-free for a given period of time, at what point do they become no
riskier, or at least not notably riskier, than the general population or
people without criminal records? Alfred Blumstein and Kiminori
Nakamura have labeled this concept “redemption” — suggesting that
the passage of some number of recidivism-free years should be under-
stood to “redeem” the individual in the eyes of society.
238
Estimated
times to redemption appear to vary across samples, crime types, age
cohorts, and methods, but they are usually in the range of four to ten
years, at least when juxtaposing individuals with records to the same
age cohort within the general population.

, supra note 237, at 8. This religiously derived language has
potential connotations (for example, the idea that those with records are “fallen”) that are probably
not intended by any of the scholars using it and that we do not endorse; still, we use the term here
in deference to the leading work on desistance from crime.
239
See generally Blumstein & Nakamura, supra note 237. If instead the contrast is drawn with
only people who have no prior criminal record (instead of the general population, which includes
people with records), then redemption studies tend to find that the recidivism risk of people with
records never converges completely to the risk levels posed by individuals without records, see id.
2520 HARVARD LAW REVIEW [Vol. 133:2460
One could easily interpret the low recidivism rates we find in section
III.A — and the favorable comparisons to general-population arrest
rates — as indications of redemption. Expungement recipients have all
gone at least five years without a subsequent conviction before receiving
their expungement; the median period between conviction and expunge-
ment is nearly ten years.
240
Moreover, by definition, expungement re-
cipients in our data were all individuals without any prior record when
they were convicted of their expunged offense — and recidivism studies
consistently find that the length of one’s existing criminal record is a
strong predictor of subsequent recidivism.
241
And, as we note above,
the group that receives expungements is self-selected and selected by
judges. Taken together, then, there are many reasons to believe ex-
pungement recipients may be at a low baseline risk for recidivism.
It is, however, also quite likely that receiving an expungement re-
duces a recipient’s recidivism risk below their previous baseline. This
possibility is supported by criminological research on the factors pre-
dicting recidivism.
242
Recidivism-related benefits of expungements are
likely to be mediated primarily by their effects on employment and wage
levels — which we assess below in Part IV. Unemployment is a moder-
ately strong predictor of recidivism.
243
Likewise, higher weekly wages
significantly reduce recidivism risk.
244
A study of women with records
indicates that “poverty status increases the odds of rearrest by a factor
of 4.6” and is a better predictor of rearrest than a recidivism-risk index

commonly used in corrections.
245
Homeless individuals with criminal
records are especially likely to recidivate,
246
while people who receive
educational programming while incarcerated are less likely to recidivate
upon release.
247
To the extent that criminal records limit access to qual-
ity housing, student loans, satisfying employment, and decent wages,
expungement should reduce recidivism by mitigating each of these soci-
oeconomic contributors to criminal behavior.
Another possibility is that expungement reduces recidivism by alle-
viating the social exclusion that is often associated with criminal records.
People with records face significant social stigma,
248
which is exacer-
bated by employers’ growing reliance on increasingly available online
criminal records databases.
249
Sociologists and criminologists have long
argued that social stigma and exclusion can contribute to criminal re-
cidivism.
250
Although little empirical support has been found for the
strongest claims of 1970s-era labeling theorists (for example, that label-
ing individuals renders criminal justice interventions actually counter-
productive on net),
251
stigma and exclusion may still be an important
part of the dynamic underlying recidivism.
252
All in all, it is highly plausible that expunging criminal records could
benefit public safety, given what we know from a large body of research
about recidivism patterns generally. In contrast, no similarly plausible
empirical support exists for the opposite claim, one that lies behind re-
sistance to expungement laws: that sealing records increases recidivism

risk. To our knowledge, those raising this objection have never pre-
sented evidence supporting it, and its rationale is not obvious.
The intuition seems to be that those who know an individual’s crim-
inal background can take steps to protect themselves — for example, by
choosing not to hire the person. And as the empirical evidence we dis-
cuss in section I.A indicates, many U.S. employers do exactly that. But
while such a step might be in an individual employer’s or landlord’s
self-interest, it is hard to see how it would be in society’s interest overall,
given that lack of employment, unstable housing, and social stigma are
all risk factors for recidivism. Even if a person with a record is at an
elevated risk of committing crime, the employer who declines to hire
that person simply shifts risks to others, or even amplifies those risks.
253
No empirical research shows that the collective effect of decisions not to
hire or rent to people with records makes society safer. Notably, the
purported public-safety case against expungement follows the same
logic as the purported public-safety case in favor of sex offender regis-
tries with public notification requirements — yet empirical research has
shown that these laws may actually increase recidivism.
254
With that in mind, let’s return to the question we raise at the begin-
ning of this section. Suppose that a state were considering making ex-
pungement more broadly available to those with records: making it au-
tomatic for some subset of individuals with records, shortening the
waiting period, or loosening eligibility requirements. If these new clas-
ses of recipients have a higher baseline risk of recidivism than current
recipients do, their post-expungement recidivism rates will also proba-
bly be higher — maybe substantially so.
But from a policy perspective, this possibility is a red herring. The
higher recidivism risk would not be caused by the expungements or by
the law change that allowed them; it is simply a baseline risk, which
would exist with or without expungements. A higher recidivism rate is
not relevant to the cost-benefit analysis unless it is an effect of the law
change or the resulting expungements. But there is no credible evidence
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
253
There is at least one plausible counterargument. There may be situations in which someone
with a history that includes a particular crime applies for a position that would put them in an
especially favorable position to recommit the same or a similar offense. Further, that criminal op-
portunity would not be available at another location or with another employer. Many employers
and landlords might prefer to use a public criminal record to reduce the likelihood that this person
reoffends in that place or in that situation. However, while theoretically possible, situations of this
sort in which crime is not simply displaced seem likely to be very few, and, more importantly, the
negative effect that employment and housing difficulties can have on general recidivism factors is
likely to overshadow any benefit. Cf. J.J. Prescott, Portmanteau Ascendant: Post-release Regulations

to support the idea that risk might grow because of the greater availa-
bility of expungement relief. Meanwhile, existing research provides firm
grounds to believe that, if anything, recidivism would fall. Put another
way, if expungement reduces recidivism, then granting it to a pool of
new recipients with higher underlying recidivism risk simply offers a
greater potential public-safety upside.

UTCOMES
Although record clearing can simultaneously address a range of col-
lateral consequences of criminal convictions, probably the most im-
portant motivation for most expungement applicants
255
— and the most
important policy rationale for expungement laws — is to improve access
to employment. As we discuss in Part I, well-developed theoretical ac-
counts convincingly explain why criminal record expungement should
have positive employment consequences for recipients, but the empirical
evidence on the question remains extremely limited.
256
This is a huge
problem as advocates and policymakers negotiate the future of expunge-
ment policies. In this Part, we hope to at least begin to resolve it. Sec-
tion IV.A presents estimates and figures comparing pre- and post-
expungement wage and employment trajectories for our large sample of
recipients; these show large gains in both employment rates and wages
following an individual’s receipt of an expungement. Section IV.B ad-
dresses the question whether these gains can be interpreted as causal

255
A sample of individuals who received record-clearing relief in California “expressed frustra-
tion with their inability to gain employment [with their criminal record], noting that the limited
jobs open to them predominantly involved poor working conditions and low pay . . . . They genu-
inely hoped record clearance would increase their employment potential and facilitate their success-
ful reintegration into society.” Adams et al., supra note 95, at 30. In another survey of people
seeking expungement of criminal records in Chicago, participants reported suffering ongoing stigma
from their record: “Even participants with extensive histories who had remained ‘clean’ for lengthy
periods reported criminal record related stigma and material hardship.” Ispa-Landa & Loeffler,
supra note 32, at 398. For example, “a 44-year-old man who had 12 arrests on his rap sheet [and]
had been convicted of drug possession and unlawful use of a weapon 19 years earlier” said that “he
could easily find several references who would vouch for his work ethic and skills, but even these
personal testimonies did not compensate for his criminal record.” Id.

effects of receiving an expungement, offering additional results to help
us come to grips with this important question of interpretation.
A. Employment and Wage Trajectories for Expungement Recipients
The outcome data we use in this work are quarterly Unemployment
Insurance Agency (UIA) wage data collected for expungement recipi-
ents. The data run from the third quarter of 1997 through the second
quarter of 2013. The sample inclusion criteria we use to conduct our
analysis are as follows: (1) The individual received an expungement on
a known date between January 1998 and May 2011.
257
(2) The individ-
ual did not possess a non-Michigan driver’s license identified in our
criminal history data. (3) The individual matched to the UIA data in at
least one quarter during the period from 1997 to 2013.
258
And (4) The
individual is of working age (eighteen to sixty-four) for the entire time
over which we observe their wages for a particular regression.
We examine both employment status and wages as outcomes. We
structure our dataset for the research in this Part as a panel — that is,
we follow the same individuals before and after they receive their ex-
pungement, and each observation is a person-quarter.
259
For each anal-
ysis, we use a balanced panel, meaning that for every individual in our
analysis (regardless of the date of receipt), we include the same number
of quarters before and after the expungement.
260
Essentially, we use
each individual as their own control; we compare an individual’s post-
expungement employment-related trajectories with that same individ-
ual’s pre-expungement trajectories.
In Table 5, we report estimated average changes in employment
trends before and after an individual receives an expungement. The
different columns of Table 5 present these estimated changes in trends
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
257
Within each column in Table 5, the sample is further constrained to ensure that outcome data
exist for all person-quarters in the analysis. For example, if we have only five quarters of pre-
expungement data for particular individuals, we include them in the sample for Column 2, which
considers two quarters of data before and after expungement, but we exclude them from the sample
for Column 3, which includes eight quarters of data on either side of the expungement.
258
For those individuals who do match, we interpret an absence of reported wage data for a
particular quarter as implying the individual has no employment in that quarter. By contrast, we
take the total absence of someone from the wage data to imply a failure in the matching process
(for example, a missing or incorrect Social Security number, or a non-Michigan resident).

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2525
over different time windows of various widths; we place the expunge-
ment at the center of each window. We estimate the following equation
using ordinary least squares:
𝐸𝑚𝑝𝑙𝑜𝑦𝑒𝑑

= 𝛼 + 𝛾𝐸𝑙𝑎𝑝𝑠𝑒𝑑

+ 𝛿𝐸𝑙𝑎𝑝𝑠𝑒𝑑

× 𝑃𝑜𝑠𝑡

+ 𝜃𝑇𝑜𝑡𝑎𝑙𝐸𝑚𝑝𝑙𝑜𝑦𝑚𝑒𝑛𝑡
+ 𝜗𝑈𝑅𝑎𝑡𝑒
+ 𝜖

.
Our main outcome of interest, 𝐸𝑚𝑝𝑙𝑜𝑦𝑒𝑑, is an indicator for whether
an individual has any positive wages reported to UIA by any employer
in the quarter.
261
𝐸𝑙𝑎𝑝𝑠𝑒𝑑 is a linear measure of time, increasing by one
for each quarter; it is set to zero in the quarter before the individual
receives their expungement.
262
The coefficient we estimate on 𝐸𝑙𝑎𝑝𝑠𝑒𝑑
represents the underlying linear trend in employment in the quarters
prior to the expungement — that is, it is the average change per quarter
in the employment rate for the sample. A negative coefficient on
𝐸𝑙𝑎𝑝𝑠𝑒𝑑 would indicate that the group’s average employment rate was
declining prior to expungement receipt, and a positive coefficient would
indicate that it was increasing.
Our primary variable of interest, 𝐸𝑙𝑎𝑝𝑠𝑒𝑑 × 𝑃𝑜𝑠𝑡, captures the
change in the linear employment-rate trend after expungement receipt.
A positive coefficient on 𝐸𝑙𝑎𝑝𝑠𝑒𝑑 × 𝑃𝑜𝑠𝑡 implies that the employment-
rate trend improves post-expungement, and a negative coefficient con-
versely means it gets worse.
263
We estimate changes in the employment
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
261
“Any positive wages” is a very minimal threshold for deeming an individual “employed,” as
there is no minimum number of hours or total compensation requirement. Furthermore, the wages
could come only from one part of the quarter; the wage data are not further broken down tempo-
rally. On the other hand, absence of employment/wages as measured in these data does not neces-
sarily mean that the individual is truly “unemployed” in the sense that economists use the term —
that is, actively looking for a job, but so far unsuccessful. Being unemployed in our data simply
means that the individual does not have a wage- or salary-paying job. Virtually all employers in
Michigan are required to report wages, but the data do not include people who are self-employed,
nor do they differentiate between unemployed people who are looking for work and people who are
out of the workforce. See M

§ 421.13(2) (West 2020). If our real outcome
of interest is total lawful employment (including self-employment) among the working-age popula-
tion, then presence in the UIA data is a rough proxy for it. UIA-reported wages may also understate
total earnings. That said, these issues affect the data throughout the study period, and we do not
think they should substantially affect our estimation of trend changes from before an expungement
to after its receipt. If anything, classical measurement error like this tends generally to bias regres-
sion estimates toward zero — specifically, it may cause us to understate the true effect size of ex-
pungement. See J

Positive values of 𝐸𝑙𝑎𝑝𝑠𝑒𝑑 represent the number of quarters since the individual received
their expungement. We count the quarters prior to the expungement, running from negative values
up through quarter zero, which is the last quarter unaffected by the expungement.
263
The sum of the estimated coefficients of 𝐸𝑙𝑎𝑝𝑠𝑒𝑑 and 𝐸𝑙𝑎𝑝𝑠𝑒𝑑 × 𝑃𝑜𝑠𝑡 represent the post-
expungement trend in the employment rate for this group; a positive sum means employment levels
are increasing, and a negative sum means they are declining.

trend, rather than a simple one-time change in the employment level, on
the assumption that the effects of an expungement may accumulate over
time rather than being instantaneous.
264
We estimate linear trends (as
opposed to more complicated curves) for simplicity of interpretation.
But estimating these trends over a variety of time windows can help us
to detect nonlinear patterns in the actual trajectory.
265
The remaining variables in our estimating equation are measures
for economic conditions during the calendar quarter of each observa-
tion. The time period of the analysis (19972013) includes considerable
economic fluctuations, most importantly the 2008 financial crisis and
subsequent deep recession; overall it was a period of economic decline
and rising unemployment in Michigan.
266
To account for these
changes in the labor market, we include Michigan’s quarterly unem-
ployment rate and the total number of people employed in the state as
reported by the Bureau of Labor Statistics.
267
We control for these
changing economic conditions because they could potentially affect the
pre- and post-expungement periods differently. In contrast, because of
the balanced-panel structure, fixed attributes of given individuals or
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
264
In addition, especially if there is an underlying trend over time before the expungement, esti-
mating changes in levels alone can be misleading. For example, if there is a continuous upward
trend throughout the sample period, the average level would be higher in the post-expungement
period even if the growth has nothing to do with expungement receipt; at the same time, if there is
a downward trend before the expungement that reverses after expungement receipt, the average
employment levels might look the same before and after, even though there may have been a dra-
matic change in trajectory.
265
The results are substantively similar if we use logistic regression for the binary outcome var-
iables, as we did in the Table 3 uptake analysis. Here, we prefer the linear probability model
because our key variable of interest is an interaction term, and interactions are notoriously difficult
to interpret in logistic regression. See Edward C. Norton et al., Computing Interaction Effects and
Standard Errors in Logit and Probit Models, 4 S
TATA
J. 154, 15456 (2004). Linear probability
models also tend to perform well in the middle of the probability distribution, a condition that is
satisfied here (but not in the Table 3 analysis). See Paul von Hippel, Linear vs. Logistic Probability

their prior criminal records can be safely ignored, since they are
equally present before and after the receipt of the expungement.
268
In each version of the regression results in Table 5,
269
we estimate a
substantial and statistically significant (p < 0.001) upward turn in the
employment-rate trajectory of expungement recipients after they receive
their expungements.
270
The coefficients, representing per-quarter gains,
decline in magnitude as the window gets larger (although they remain
significant), which intimates that the improvements are steepest in the
first two quarters and slowly become more gradual; this can also be seen
in the net gain and proportional net gain calculations we report in Table
5.
271
By the end of one year, after controlling for the pre-receipt trend
and other potentially confounding labor-market variables, expungement
recipients gain nearly eight percentage points in their employment rate;
proportionally, they are 1.13 times as likely to be employed. The net
gain following expungement is about the same in the two-year observa-
tion period and slightly lower in the three-year period, suggesting not
only that the employment improvements following an expungement
come relatively quickly, but also that they are largely sustained in the
following years.
In Panel B of Table 5, we show the same type of analysis, but sub-
stitute a different, less minimalist definition of the employment outcome
variable. Instead of requiring only that any wages have been earned at
any time in the quarter,
E
mployed
now requires individuals to have
earned an average of at least $100 a week ($1300 total for the quarter)
before they count as employed. This is still a threshold that falls well
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
268
The standard errors that we estimate for these regressions are clustered at the person level;
clustering in this way means that the reported precision of our estimates accounts for the fact that
our quarterly observations for each person are not independent of one another.
269
The “window” range we indicate at the top of each column in Table 5 reflects the number of
quarters before and after expungement receipt and thus the sample over which we estimate our
regressions; for example, “+/- 4” means that we observe individuals for one year before (four quar-
ters) and one year after the expungement.
270
The p-value represents the probability that a randomly drawn sample of the size used by the
researcher would produce the observed coefficient (or a more extreme one) if the true coefficient of
the relationship in the underlying population were zero. It is a way of expressing statistical impre-
cision due to sampling error. See B.S.

sidered statistically significant, though even lower is better. See Johnson, supra, at 19313, 19315.
271
Near the bottom of each Panel in Table 5, “net gain” and “proportional net gain” show the
estimated percentage-point and proportional gains in employment experienced by the average ex-
pungement recipient by the window’s end, relative to what would have occurred had they stayed
on their pre-expungement trajectory. We calculate “net gain” by multiplying the estimated
𝐸𝑙𝑎𝑝𝑠𝑒𝑑 × 𝑃𝑜𝑠𝑡 coefficient by the number of quarters observed in the post-expungement period in
the column. We calculate “proportional net gain” by dividing the net gain by the average employ-
ment level in the quarter before expungement receipt (which is 61.7%).
2528 HARVARD LAW REVIEW [Vol. 133:2460
short of representing full-time employment.
272
Even so, by using this
definition, we at least exclude truly trivial earnings that may be causing
people who are for all practical purposes unemployed to be coded for
our analysis as employed. And, importantly, it may allow us to pick up
on some differences that the main
E
mployed
coding misses.
And indeed, the results in Panel B show substantially larger trend
changes than we display in Panel A. The general pattern is the same —
steeper trend changes in the narrower windows — but the magnitudes
are larger. By the end of one year, we now see a twelve-percentage-
point net gain in employment relative to the pre-expungement trajec-
tory. This implies that expungement recipients are 1.23 times as likely
to be making at least $100/week as they would have been (53% are em-
ployed at baseline using this measure of employment). As before, the net
gains are similar in the two-year window and slightly lower in the three-
year window, indicating that the employment gains largely endure but
do not continue to increase after the first year.
In Panel C of Table 5, we estimate changes in the average wage tra-
jectory of individuals following expungement receipt. We find a similar
pattern, with a steep gain in the first year followed by a subsequent
plateau in gains. By the end of the first year, relative to the pre-receipt
trend, recipients gain an average of $1111 in quarterly wages (that is,
$4444 per year), which is a 23% improvement over the pre-expungement
average; the net gain increases to $1234 in the two-year estimate, a 25%
improvement. The proportional increase in wages is much larger than
the increase in the employment rate in Panel A, but very close to the
gain we calculate using the alternative employment measure in Panel B.
This pattern implies that the increase in average wages may substan-
tially be explained by unemployed people obtaining employment or by
very minimally employed people securing more hours or higher-paying
work following their expungement. In Figures 3A, 3B, and 3C, we
demonstrate visually the employment and wage patterns that underlie
these regression estimates.

Therefore, this measure of employment represents about fourteen hours of work per week at min-
imum wage, or less at a higher wage; $100/week is less than one-fifth of the median wage among
persons with any wage in our sample.
273
In these figures, we do not model changes in employment outcomes as linear trends during
the pre-expungement and post-expungement periods. We simply show the employment rate and
average wage for each quarter beginning two years before and ending two years after the expunge-
ment (including quarter 0, the quarter immediately preceding the expungement quarter, which is
marked with a vertical dotted line), and then we connect the dots. The sample we use to create the
graphs is the same that we use for Column 3 in Table 5, Panels A–C. The graphs all have similar
patterns — a clear V-shape immediately surrounding the expungement.

adjusted to control for economic trends in Michigan. And, notably, the
downward overall pattern in each of the graphs reflects the declining
state of Michigan’s economy over the course of our study period. But
what is important to understand for our purposes is not that underlying
decline but the change in the direction of the graph in the period imme-
diately after the expungement — the sudden, V-shaped upturn.
The results that we show here are robust; that is, similar patterns
consistently continue to appear even if we vary the details of the regres-
sion specification or the sample definition.
274
For example, there are
certain additional economic control variables that could potentially im-
prove our ability to account for the influence of economic fluctuations,
but which we do not add to the main specification because we do not
have the data for all years. These include the average quarterly earnings
for Michigan from the Quarterly Workforce Indicators series (available
from 2001) and average quarterly wages and employment rates for ex-
pungement nonrecipients in our own data (available from 2004). For
the years that they are available, adding these variables into our analysis
does not change the results. In addition, one might worry that, nonetheless,

introduced by the financial crisis and recession. But the same patterns
in our data persist if we simply drop that entire time period, such that
the windows for each analysis end before 2008 begins. The same sub-
stantive story also surfaces if we leave in the sample all of the individu-
als who do not match to the wage data at all; for our main sample def-
inition, we assume their absence was likely just a failure of the
matching process, but they could also be people who were not working
for the entire period. If we include them and count them as having
zeroes for all of the outcome variables, the employment rate and average
wages drop, and our point estimates decline proportionally, but the pro-
portional net gain estimates remain the same.
We also conduct these analyses separately for different subpopula-
tions to see whether expungement affects different groups of recipients
differently. We find substantial, and largely similar, trend changes in
every subgroup. The most conspicuous pattern we discover is that wage
and employment gains are much larger for women, at least in propor-
tional terms (women have lower baseline wages). For example, in the
one year after expungement, we estimate that men’s wages increase by
17%, while women’s wages appear to increase by 30%. We are unable
to explain the difference, as there are many possible explanations; for
example, perhaps women apply disproportionately to job types for
which a criminal record is a particularly serious barrier.
275
Studies of
other kinds of job-access interventions, like job training, also generally
find much larger effects for women, so the difference in our data may be
a byproduct of a more general phenomenon.
276
We also find larger ef-
fects for black expungement recipients than for white recipients, but
this difference is not as large (one-year wage gains of 25% versus 18%).
Among both men and women, people who expunge a felony see only
slightly larger gains than those who expunge a misdemeanor (one-year
wage gains of 33% versus 29% among women, and 18% versus 16% for
men). This difference seems surprisingly small, given that felonies carry
more collateral consequences and presumably more labor-market
stigma.
277
However, relatively few misdemeanors are expunged in the
first place, so they may represent a highly selected subset — for example,

perhaps the misdemeanors people choose to expunge tend to be partic-
ularly stigmatizing for them. In any case, the estimates for all crime
categories and for all categories of individuals are large and significant.
B. Interpretation: Expungement Effect, Motivation,
or Mean Regression?
Our analysis demonstrates that expungement is associated with large
improvements in the employment rate and wages on average — and, in
particular, a reversal of the pre-expungement downward trend that we
observe for recipients as a group. Can we conclude from this evidence
that expungements cause these improvements? The answer is not obvi-
ous. A causal interpretation of the trend-change estimates above de-
pends on the assumption that, in the absence of these individuals receiv-
ing expungements, their collective pre-expungement employment and
wage trajectories would have continued on the same path. But is that
true? Absent expungement, is there some other force that might reverse
the downward slide at about the same time as receipt and give rise to
the same V-shaped pattern we observe? The control variables in the
regression already account for the role of changing labor-market trends,
which would otherwise be one plausible explanation. But there is still
the possibility of omitted variable bias — there could be something else
going on that we cannot measure or observe that accounts for these pat-
terns, other than the receipt of an expungement.
278
The most likely candidate is motivation. As we detail in Part II, it
takes a lot of effort, as well as a financial investment, to obtain an ex-
pungement.
279
Moreover, most expungement recipients choose not to go
through this effort as soon as they become eligible — three-quarters wait
more than a year, and 44% wait more than five years.
280
So, what mo-
tivates people who have waited several years to decide that now is the
time to apply? From an inference perspective, it would be ideal if their
decision were random, but it probably is not. For many, it may be that
they are trying to get a job — perhaps because they have been laid off,
or because they are seeking out better pay.

some support in our findings in Column 5 of Table 3: People are more
likely to receive an expungement within a year of a job loss or substan-
tial decline in wages. And a person who is motivated to improve their
employment situation to the point that they are willing to go through
the burdensome expungement process is probably taking other steps to
better their prospects, too — like applying for jobs, obviously. So, if we
see a turnaround in their employment trajectory just after the receipt of
their expungement, could the change actually be due to these other steps,
with the expungement merely incidental?
A related causal-inference concern is the possibility that our empiri-
cal findings are simply the product of statistical regression toward the
mean.
282
Consider a classic example often used to explain the concept:
both very tall parents and very short parents tend, on average, to have
children who are a little closer to the populations average height than
they are.
283
Although height is substantially hereditary, people do not
turn out exactly like their parents; there is randomness involved in gene
mixing and in the operation of other influences on height. Parents who
are extremely tall or short are likely that way partly because of random
noise, and their children are unlikely to get the same roll of the dice.
284
Similar patterns are found in other real-world phenomena involving
random fluctuations — extreme outcomes tend to be followed by less
extreme ones
285
for the straightforward reason that most outcomes are,
by definition, not extreme.
286
A similar phenomenon could explain some of our results. Suppose
there is a certain amount of random variation in individual wages and
employment status (or as good as random for our purposes — uncorre-
lated with the other variables of interest in our analysis). Suppose fur-
ther that people tend to apply for expungement when they have recently

sion. Furthermore, because retail and service sector jobs involve extensive contact with the public,
employers may be especially reluctant to hire CJS-marked individuals.” (citations omitted)).

experienced an employment setback, so they are more likely to seek re-
lief when they are on the downside of one of these random fluctuations.
Then, even leaving to one side any broader job-search motivation that
may be correlated with an individual interest in expungement, one
might expect that downward trend to reverse itself at around the time
an individual receives an expungement. Our analysis assumes that an
existing downward trend in employment outcomes observed across a
sample should be expected to continue without some clear reason for it
to change — like receiving an expungement. Such an expectation is
sensible when the underlying trend is driven by durable, real-world fac-
tors. But if the trend is not substantive but rather the product of ran-
dom noise, then such an expectation can confound causal inference and
lead one astray, especially when a trough in employment circum-
stances activates an understandable tendency among those eligible to
apply for an expungement, inducing a spurious correlation.
Unfortunately, there is no entirely clean way to unravel these causal
conundrums in our data. In truth, it is likely that all of these factors
contribute to the large apparent employment effects we find — that is,
expungements do bring about employment gains, but the gains caused
by expungement receipt are not quite as large as those we estimate
above. Indeed, the effects of motivation spillovers and record clearing
might be expected to be mutually reinforcing: perhaps the motivation
drives the job search, but the expungement makes the search more likely
to be successful (and that prospect in turn may increase motivation),
suggesting an even more reticulated causal story.
Fortunately, our data do provide a couple of reasons to believe that
causal effects of expungements probably explain at least a large part of
the trend changes we observe. The first reason concerns the exact tim-
ing of the upturn. The motivation and mean-regression theories both
hinge on the idea that people apply for expungements at particular times:
when they are motivated to seek work and/or when they have recently
experienced the loss of a job or wages. But there is a significant period
of time between application and receipt, and our analysis focuses on the
date of receipt of the expungement. It takes at least a few months to
receive an expungement,
287
and this time lag implies that, in our quar-
terly wage data, any motivation or mean-regression effects should begin
to be visible even two quarters before and definitely one quarter before
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
287
Lamentably, we do not know the date of the application for expungement in the great ma-
jority of observations in our data, and the time lag between application and receipt reportedly
varies by a fair amount, depending on geography and so forth. But our conversations with ex-
pungement lawyers in Michigan and with representatives of the Michigan State Police suggest
that it is very hard to complete the process in less than two months, and that (while some jurisdic-
tions have recently achieved efficiency improvements) three to six months was a more common lag
during the years covered by our study. See supra note 161 and accompanying text.
2536 HARVARD LAW REVIEW [Vol. 133:2460
expungement receipt. We might expect to detect motivation effects even
earlier because the impetus to seek a job might often be around for a
while before any expungement application.
But what we see in the data does not seem to match this alternative
story — or at least, it matches it at best only weakly. In Figures 3A, 3B,
and 3C, the first quarter in which there is a change in trajectory — an
upswing from the prior quarter — is quarter 1, the quarter in which the
individual actually receives the expungement.
288
In that quarter, we
spot a very slight improvement from the previous quarter — which does
represent a substantial change, stopping the previous downward trajec-
tory — and a much steeper upward pivot between quarters 1 and 2 for
the first employment curve (Figure 3A), and between quarters 2 and 3
for Figures 3B and 3C. This type of pattern is very much what we
would expect to observe if expungement receipt (and not other factors
correlated with an expungement application) drives the change in tra-
jectory.
289
If the shift in the trend were instead triggered by something
happening a quarter or two earlier (e.g., the motivation accompanying
the choice to apply for an expungement), we would likely see a similar
pattern, only shifted a quarter or two to the left. But we see no trend
change until quarter 1 in any of these graphs.
290
It is possible that what
occurs between quarter 0 and quarter 1 includes some component of the
mean-reversion or motivation effect — we cannot rule this out. But the
pattern is more consistent with changes being driven at least quite sub-
stantially by expungement receipt.
Second, we provide a further test of this causal theory in Table 6 by
analyzing a specific subset of our sample: those who receive expunge-
ments within one year of becoming eligible to apply. As we explain
above, we consider these cases (accounting for 25% of all expungements,
and 19% of the wage-linked sample) to be primarily “pent-up demand”
cases — people just waiting to become eligible.
291
These individuals are
obviously motivated to obtain an expungement, but there is no reason
to believe that this motivation would have materialized just at the time
of their application or, alternatively, as a consequence of some recent

289
We only discern about half of the trend change in the partial post-expungement quarter
(quarter 1); the trend change appears in the figures in full bloom beginning only in the first quarters
that fall fully in the post-expungement period.
290
Indeed, in the wage graph (Figure 3C), the fall between quarters –1 and 0 is particularly
steep.

employment setback.
292
Motivation that is longer term rather than spe-
cific to the particular time around the expungement is unlikely to con-
found our results because it would not explain a turnaround in the trend
at the time of expungement receipt. Likewise, we worry less about re-
gression to the mean when we study this sample because there is less
reason to believe that an individual’s choice to apply at the culmination
of the waiting period is motivated by finding themselves at the bottom
end of a random fluctuation in their employment outcomes; rather, they
are simply applying the first chance they get.
The regressions in Table 6, Panels A–C, directly parallel those in
Tabl e 5, Panels A–C; we carry out the same analyses on the smaller
pent-up” sample. Table 6 demonstrates very strong gains in employ-
ment and wages after receiving an expungement — changes that remain
statistically significant (p < 0.001 for almost all estimates) despite the
loss of power accompanying the sample’s smaller size.
293
Early ex-
pungement recipients become, by two years after expungement receipt,
1.12 times as likely to be employed at all using our “any wages” measure
(a seven percentage point gain) and 1.2 times as likely to be employed
for at least $100 per month (ten percentage points), and they earn 1.24
times their prior wages on average.
The most important difference between these results and our Table 5
findings concerns the pre-expungement underlying trend, which is nega-
tive in all Table 5 specifications. By contrast, the early-expungement
group exhibits no significant prior trend for most windows and outcome
variables, consistent with our theory of pent-up demand.
294
In other
words, the arrival of the five-year threshold for these individuals is ef-
fectively random; it does not coincide with any particular pattern in pre-
expungement employment outcomes. Thus, mean regression cannot ex-
plain the subsequent trend changes because there is no prior downturn
from which to regress. It is also hard to explain by a job search — there
is no prior setback to explain its arrival, and moreover, the timing of the
expungement for early recipients seems to be driven mechanically by the

that under the Rubicon model for analyzing motivation, a persons course of action may be sepa-
rated into phases that include a predecision phase — where a person begins setting goals — and a
preaction phase — where a person begins goal-directed behaviors).
293
The timing of the largest gains is slightly later (the curves are slightly less steep in the six-
month window), but by the end of two years, the net gain in proportional terms is essentially
identical to what we observe for the broader group in Table 5.
294
Table 6 offers evidence in support of our causal account of expungement receipt: the flat prior
trend, which is followed by a steeply positive post-expungement trend, is inconsistent with early-
expungement recipients applying for expungement in the wake of an employment downturn. Ad-
mittedly, a few of our specifications hint at a small negative pretrend in employment outcomes,
but others actually produce positive coefficients on 𝐸𝑙𝑎𝑝𝑠𝑒𝑑, our trend variable.

eligibility clock.
295
Perhaps the absence of mean regression and motiva-
tion effects slightly dampens the immediate effects we estimate in the
shortest time window, but by two years the gains are just as large. This
result provides quite good reason to believe that the employment and wage
gains are substantially caused by expungement.
In Figure 4, we present a variant of the wage graph from Figure 3C;
this version, perhaps, provides more compelling visual evidence of the
causal explanation of our results. This analysis is limited to the early-
expungement sample, and it is also residualized — that is, we use re-
gression analysis to remove the underlying downward trends attributa-
ble to secular changes in the economy. This graph shows little evidence
of any downward trajectory for individual wages before expungement.
Rather, it presents a noisy but essentially flat pattern, which abruptly
turns upward after expungement receipt.
296
The results from the early-expungement sample are encouraging in
another sense as well: they suggest that similar employment benefits
might accrue in states that make expungements automatic after a fixed
period of time post-conviction.
297
One might otherwise worry that the
employment gains depend on the fact that expungement recipients like
those in our data are a self-selected group who choose to apply just
when they are hunting for a job. Even if the expungement does help
(that is, it has a causal effect) in obtaining employment or better wages,
one would not necessarily expect a similar effect to emerge if a recipient
is not job hunting in the first place.
298
But in the early-expungement sample, the timing of the expunge-
ment is less likely to be determined by an individual’s search for better
employment circumstances; rather, for most of this group, expungement
timing is dictated by the arbitrary five-year waiting period. And that
perhaps explains why the gains for this group are slightly slower to ar-
rive — but still, they arrive fully within two years of the expungement.
If expungement kicked in automatically after five years (or some other
time threshold), presumably most recipients would not happen to be
looking for a job (or a better-paying job or one with more hours) at that

296
For space reasons, we show only the wage graph here and not the other outcome variables.
The graphs of the employment measures, when we construct them using the early expungement
sample and residualized, do show a slight decline in the quarters before expungement receipt, but
it is much smaller than what we observe for the full sample.
297
For a list of states that have led this policy shift, see supra section I.B, pp. 247276.
298
In other words, we worry that receipt of an expungement might have heterogeneous effects
on employment outcomes, depending on whether someone is hunting for a new job, which might
be unobservable. Cf. Patrick Arni & Amelie Schiprowski, Job Search Requirements, Effort
Provision and Labor Market Outcomes, 169 J.

Notes: Quarter 1 (immediately after the dotted line) is the quarter of expunge-

expungement between January 1998 and May 2011, did not have an out-of-

the period from 1997 to 2013, and were of working age (eighteen to sixty-four).

almost everyone looks to improve their employment situation eventu-
ally — and probably more frequently among people with records, who
tend to be in lower-paying jobs with higher turnover.

In sum, the causal interpretation of our results is on all fours with
many patterns in our data that are otherwise difficult to explain — and
with what we should expect based on extensive research showing that
criminal records pose substantial hurdles to employment success.

findings are consistent with the intuition that expungement of those rec-
ords should help to reduce those hurdles.
Notably, our analysis is based entirely on expungements received in
the age of the internet.
301
Thus, our results suggest that it is possible
for record clearing to generate substantial benefits for individuals with
records notwithstanding the search tools currently available to employ-
ers. And this, perhaps, should not be surprising. Many arrests and
convictions are not especially newsworthy and do not create a long trail

Employers, after all, overwhelmingly pay to
carry out background checks using criminal records databases; they do
so presumably because they believe that the database they patronize will
provide them with much more comprehensive and reliable information
than they could otherwise obtain for free.
303
And Michigan’s experience demonstrates that expungement can, in
fact, succeed in excising convictions from these databases.

is probably to be expected under the circumstances. Companies that
manage these databases obtain their records from the state and update

based background research had become pervasive.

and thus failing to observe this requirement potentially ex-
poses them to criminal prosecution.
307
In all of our conversations with
expungement advocates in Michigan, none mentioned any concerns
about the practical effectiveness of expungements at limiting employer
access to records, even though similar concerns have been raised often
in the course of debates about expungement reform elsewhere.
308
To be sure, our data do not establish that expungement works per-
fectly in all cases to hide records from the public eye; it is likely that
some individuals really cannot escape the digital trail of their prior con-
victions, and mistakes could well persist for some individuals who have
had their records cleared in some criminal history databases.
309
More-
over, a clean record obviously does not automatically translate into a
new or better job; the search for employment involves many other fac-
tors, and not every expungement recipient will end up experiencing em-
ployment benefits (although some will presumably experience benefits
in other areas of life as well). The employment and wage gains that we

Roberts mentions that some states do have their own credit reporting acts, and these are a way of
“limiting access to and use of sealed and expunged records.” Roberts, supra note 97, at 345. Mug-

Haber argues that digital access to records poses a constant threat to record clearing, Haber, supra
note 97, at 356, and expungements “must be revisited and revised to address the challenges of digital
technology to rehabilitation,” id. at 384. “‘Mugshot’ websites post photos from the day’s arrests,
often free of charge except to those who must pay to get expunged charges taken off the site. Web-
sites like ‘Instant Checkmate’ encourage a quick check of criminal records and social media before
a date.” Roberts, supra note 97, at 329 (footnotes omitted). Roberts argues that sealing and ex-
pungement laws can be made more effective by “ensuring the accuracy of records, restricting ways
in which decision makers with access can use records, and effective regulation of background
screening companies and private companies that sell mugshots and other arrest and conviction
information.” Id. at 344. Clay Calvert and Jerry Bruno argue that journalists are positioned to
balance the competing interests of expungement laws and the First Amendment guarantee of a free
press: “[I]f a newspaper publishes a story regarding the arrest of an individual, then it takes on an
ethical obligation to subsequently report on the expunction of that same individual’s record should
such a resolution occur.” Calvert & Bruno, supra note 97, at 14344.

This Article does not seek to address comprehensively all policy con-
cerns surrounding reform of expungement laws. Some arguments raised
by both proponents and opponents do not depend on empirical claims
and are not subject to evaluation by data-driven studies like ours. For
example, expungement advocates often argue that people who have com-
pleted their sentences following a conviction deserve a second chance and
should not be punished and stigmatized forever.
310
The case for a “clean
slate” is sometimes framed in terms of forgiveness and redemption, lan-
guage that, as we note above, alludes to various religious traditions.
311
The affirmative case for expungement reform can also be framed in terms
of equality, as seeking to help people with records escape the permanent
form of second-class citizenship that effectively results from the collateral
consequences of convictions.
312
At the same time, some expungement
opponents contend that sealing records (and allowing people who have
been convicted of crimes to explicitly state the opposite) is dishonest and
at odds with freedom of information, government transparency, and the
public’s right to know.

2544 HARVARD LAW REVIEW [Vol. 133:2460
These arguments essentially involve questions of principle, values,
and preferences, not data or empirics, and fully engaging them is beyond
our Article’s scope. Instead, in this Part, we briefly address two other
possible objections to expungement laws that do connect more directly to
the substance of our evidence and argument: the crime and labor-market
consequences of expungement laws.
A. General Deterrence
When evaluating the effects of expungement on crime, one might ob-
ject that our focus on subsequent recidivism rates of expungement recip-
ients is incomplete. Record-clearing policies can influence crime rates
through other channels — in particular general deterrence, especially of
those who do not presently have records. Perhaps some people are de-
terred from committing crimes by the knowledge of the many ways in
which having a criminal record might harm them, such as embarrassing
them in their communities or interfering with their future employment
and housing prospects.
314
The concern, therefore, is that expanding ex-
pungement opportunities (especially through a much broader and/or au-
tomatic expungement policy) may conflict with general deterrence —
that is, deterrent effects on the population as a whole — and do so in a
way that produces a net increase in crime.
Such a consequence is theoretically possible, but once we inspect the
argument’s basic premises, we are skeptical of it. Our study does not
evaluate general deterrence effects, nor has any study of expungement
laws.
315
But other existing research provides many reasons to expect
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
(“First Amendment purists and open government advocates . . . argue that when it comes to combatting
crime, criminal justice agencies and courts do a better and fairer job of preventing and solving crime

EV
. 88, 88 (2016) (“Crim-
inalizing an act that provides weak signals about a person’s productivity and character can dilute
the stigma attached to having a criminal record.”). Indeed, this possibility has been raised in the
context of sex offender community notification laws, and there is at least some evidence that concern
over being publicly labelled as a “sex offender” might reduce the number of first-time offenses,
although the evidence, even in this context, is mixed. See Prescott & Rockoff, supra note 254, at
181 (finding some evidence that community notification may reduce the frequency of first-time sex
offenses but also that it may exacerbate recidivism among those subject to it).
315
Recently, there has been some experimental research on record expungement, however. See
Romain Espinosa et al., The General Versus Specific Deterrence Effects of Expungements:
Experimental Evidence 13 (George Mason Univ., Law & Econ. Research Paper No. 19-10, 2019),
https://ssrn.com/abstract=3379701 [https://perma.cc/LGF7-9C6J] (reporting results from a lab ex-
periment on expungement and its influence on criminal behavior and suggesting that the effect of
expungements on general deterrence varies based on cost but that “[t]here is no effect of expunge-
ments on specific deterrence,” id. at 1).
2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2545
such effects to be minimal (at least when the record-clearing laws in ques-
tion are similar to those most states have in place or are presently consid-
ering). If anything, they are very likely to be outweighed by salutary spe-
cific deterrence effects on those who already have records.
First, general deterrence effects are relevant only if potential offend-
ers are not only aware of the collateral consequences of criminal convic-
tions,
316
but also cognizant of the availability of expungement. But even
people who already have criminal records and are legally eligible for ex-
pungement under existing record-clearing laws rarely know about or un-
derstand the opportunity. We doubt that — even if broader laws were
enacted — general public knowledge of it would be particularly wide-
spread, especially prior to a criminal conviction.
317
Similarly, studies of
the effects of other legal shocks on general criminal deterrence emphasize
that deterrence depends on perceived consequences, not actual ones,
318
and they stress that most people do not have a very good understanding
of the law that governs them, a phenomenon that tends to undermine
deterrence effects.
319
Even in a world without record clearing, individu-
als considering committing crimes may be overoptimistic when thinking
about potential labor-market and other collateral consequences. They
may be unaware of many of those consequences and also dismiss the like-
lihood of getting caught.
Second, the existence of waiting periods ought to almost completely
eliminate general deterrence concerns. This is especially so for fairly long
waiting periods, like Michigan’s current five years, and even more so for
the up-to-ten years the new Pennsylvania and Utah automatic expunge-
ment laws require.
320
It might be less true where waiting periods are
shorter, such as under California’s new law, but even in that case, the law
requires an individual to at least complete their sentence, delaying the
availability of expungement.

2546 HARVARD LAW REVIEW [Vol. 133:2460
Intuitively, we have a hard time imagining the potential offenders
who would (absent expungement) avoid committing a crime out of fear
of social stigma, job loss, or other collateral consequences, but who would
decide to commit the crime after all if they became aware that five or ten
years later they might, if they keep their record clean and are otherwise
eligible, be relieved of some of those consequences.
322
This possibility
seems especially unlikely under a petition-based regime involving uncer-
tain judicial discretion. What is far more likely to be salient to these po-
tential offenders is the immediate consequence of losing the job they have
now, or embarrassing themselves or their families now (in addition to the
sentencing consequences). The possibility of expungement many years
down the road is comparatively remote and indefinite, and even at best
it does not undo many of those consequences; it simply stops them from
continuing to accrue over time.
Support for this intuition derives from the substantial literature ad-
dressing the effects of differences or changes in expected sentences on
crime rates.
323
In general, this research finds that criminal behavior is
not particularly sensitive to changes in the expected sentence, especially
not to additional years of incarceration beyond the first few.
324
Research
instead indicates that deterrence is best achieved through certainty and
celerity of punishment — for example, by visibly increasing policing.
325
Partly, this failure of deterrence is a function of people not understanding
the relevant laws, but it is also because most people have high, even hy-
perbolic, “discount rates” — we simply do not care nearly as much about
things that will happen to us years from now as we do about things that

In support of our conjecture, research indicates that individuals living in states that decrimi-

will happen today.
326
This basic feature of human psychology, which
may be even more present in lawbreakers,
327
has been documented in
wide-ranging contexts.
328
And its pervasiveness strongly implies that the
possibility of an expungement years later is unlikely to sway a person’s
decision to commit a crime today.
329
Furthermore, even beyond the ef-
fects of the waiting period’s implicit delay, scholarship on general deter-
rence suggests that people are simply less responsive to the consequences
of being caught for a crime in the first place than one might expect based
on traditional economic theory.
330
Third, if one broadens the analysis to encompass general deterrence
effects, it also makes sense to take into account yet another channel by
which expungement might influence crime: the specific deterrence of po-
tential expungement recipients. That is, one must consider how the pos-
sibility of expungement affects the incentives of the many people who
already have criminal records, not just those who are contemplating the
commission of first offenses.
331
After all, most crime is committed by re-
peat offenders. And these effects, intuitively, cut in the opposite direction
— and not just after expungement, which is the subject of our recidivism
discussion in Part III. Just about every state that makes expungement
available conditions it on some period of good behavior — which creates
incentives for good behavior before the waiting period expires.
332
To be
sure, such effects have not been studied either, and they too depend on
potential offenders knowing about the expungement law and caring
about the consequences of a clean record. But even though knowledge
of expungement laws is limited even among this subpopulation, people
who are already convicted and potentially expungement-eligible are, in-
tuitively, at least somewhat more likely than members of the general pub-
lic to be aware of such policies and to consider their benefits germane to

J.J. Prescott and Jonah Rockoff, supra note 254, do find some evidence that the possibility of
becoming a publicly registered sex offender many years in the future can deter first-time sex of-
fenses, see id. at 181. However, inclusion on a sex offender registry is an unusually well-known and
widely feared collateral consequence; Prescott, supra note 253, observes that other collateral conse-
quences (and even sentencing consequences such as those we discuss here) are likely less salient to
potential offenders, see id. at 1040.

their decision making. After all, these people are living at that moment
with the often-significant collateral consequences of their records; if they
are struggling to find a job or housing, the possibility that another clean
year or two could entitle them to an expungement might be much more
salient to them than expungement opportunities are to the general public.
Finally, it bears noting that the theoretical possibility that general de-
terrence of criminal behavior might decrease in a world with expunge-
ment is an argument that, at its logical extreme, can be deployed against
any reform meant to reduce the harshness of the criminal justice system’s
consequences. But it cannot be the case that anything that makes the
lives of people with records worse is better; this notion is at odds with all
reentry efforts and all policy-based limits on punitiveness. At some point,
the costs of such an approach to individuals and communities outweigh
the benefits. In this case, the purported general deterrence concern is
purely theoretical, tentative at best, and fragile on its own terms. Absent
strong evidence supporting its practical importance in the expungement
context, policymakers ought to give the general deterrence argument
very little weight.
B. Statistical Discrimination or Stereotyping
A different objection relates to the potential unintended labor-
market consequences of expungement laws. The precise worry is that if
employers really do not want to hire people with criminal records, wall-
ing off information about applicants’ records will simply cause them to
pursue that objective in other, potentially more pernicious ways. Specif-
ically, employers might instead rely more heavily on perceived proxies for
criminal records, such as race — which could amplify racial disparities
in employment.
333
This phenomenon is referred to as statistical discrim-
ination, or — if employers’ assumptions about who has criminal records
are inaccurate or exaggerated — stereotyping.
334
The strongest empirical support for this concern comes from recent
research by one of us on the effects of Ban-the-Box laws. In a large, ran-
domized field experiment that varied the race of fictitious job applicants,
Agan and Starr find that after Ban-the-Box went into effect in two

jurisdictions, white applicants’ advantage in receiving callbacks from af-
fected employers skyrocketed by more than a factor of six.
335
These find-
ings suggest that large numbers of employers appear simply to assume
that most or at least many black applicants have criminal records. Un-
derstandably, we are often asked whether we ought to expect expunge-
ment laws to have a similar effect.
This question is legitimate and worthy of study in the future; we are
aware of no empirical evidence on this concern yet. But we believe that
at least under the vast majority of current and proposed expungement
policies, there is little reason to fear a substantial increase in racial dis-
crimination. An important difference between expungement and Ban-
the-Box restrictions is that Ban-the-Box explicitly takes away all crimi-
nal record information on all applicants, at least during the early stages
of the hiring process, when significant screening occurs.
336
Employers
reviewing applications are left completely in the dark as to who has a
criminal record — even as to very serious, very long, and very recent
criminal records. Expungement policies, in contrast, are much more tar-
geted in their approach; most conviction records will never be expunged,
and recent (and thus much more informative) records categorically can-
not be expunged under the law in most states. Moreover, in a jurisdiction
with an expungement law, employers can collect information on criminal
records, and anybody with a non-expunged record can be required to
provide that information.
So employers under an expungement policy still have access to a lot
of information about criminal history; this should reduce their incentive
to rely on factors like race as a proxy for it. In Michigan, for instance, if
an employer sees that an applicant reports having no record, it is vanish-
ingly unlikely at present that the applicant actually has an expunged rec-
ord; there are ten million people in Michigan, and only around thirty
thousand expungement recipients. Even if expungement were made au-
tomatic, expanding the size of the latter group substantially, it would still
be fairly unlikely for any particular applicant to have received an ex-
pungement.
337
Moreover, even if the applicant does have an expunged
record, at worst, it would be an old and likely less serious one, followed

quirements.
338
This possibility provides little incentive for employers to
engage in statistical discrimination.
What’s more, all of this assumes employers know expungement laws
exist at all. Ban-the-Box laws have been very salient to employers, who
were forced to change their applications and were mandated to refrain
from asking about something that had always been a traditional part of
their process.
339
Expungement law is not salient in the same way. Em-
ployers need do nothing, and they can continue to ask the questions (and
run the background checks) that they always have. And, if most people
with expungeable records are unaware of record-clearing opportunities,
it seems very likely that many employers will be in the dark about them
as well.
All of that said, there can be no doubt that the landscape of expunge-
ment reform is changing, and the more sweeping expungement policies
become, the more reason there will be to worry about the possibility of
statistical discrimination by decision makers. If an expungement policy
is so broad that it leaves employers effectively without much useful crim-
inal record information at all, they might indeed react much as employers
do to Ban-the-Box policies. Among current expungement laws, Califor-
nia’s may come closest to raising this concern, since it appears to apply
to a broad swath of criminal offenses, albeit relatively minor ones, and
has (for some crimes) no post-sentence waiting period.
340
Therefore, the
effect of this and similarly expansive laws on racial discrimination is
worth assessing via future research.
C
ONCLUSION
As states throughout the country continue to debate the adoption and
expansion of expungement laws, it is important for their decisionmaking
to be guided not by hype or supposition, but by empirical evidence. Prior
to the work we present in this Article, policymakers have had very little
at their disposal. Fortunately, Michigan’s experience with expungement
provides a great opportunity to evaluate how these laws work in practice
and what their consequences are likely to be. The challenges faced by
people with records in Michigan are fundamentally similar to those faced
by their counterparts in other states, and many features of Michigan’s
law — for example, its coverage of felonies and violent crimes and its

middle-of-the-road waiting period — make the state’s experience with
expungement particularly relevant to assessing the likely effects of re-
forms nationwide. We hope the findings we document in this study, the
first of its kind, will provide helpful guidance for those crucial policy
decisions.
Taken together, our findings strongly support increasing the availa-
bility of expungement — and particularly efforts to make expungements
automatic, or at least procedurally easy to obtain. Those whose records
are expunged experience large gains in employment rates and wages —
and while some of these gains may have their source in other factors such
as underlying motivation, expungements very likely cause a substantial
portion of these improvements. The expungement effects we uncover
imply that record clearing compares favorably as a strategy to other pol-
icy interventions that seek to improve employment outcomes. Take, for
example, job training — a common public investment. A meta-analysis
of thirty-one studies covering fifteen different publicly funded job-train-
ing programs finds average unweighted gains in annual wages of $832
for women and $471 for men.
341
Like expungement recipients in
Michigan, participants in these programs were self-selected; they pur-
sued the programs because they thought they would benefit from them.
And they did benefit — but not nearly as much as expungement recipi-
ents do (annualized, the wage gains for our sample come to $4594 for
women and $4295 for men).
342
Meanwhile, the average cost of these job-
training programs to the government was $6600 per person.
343
Expunge-
ment, in contrast, has comparatively minimal costs (running a back-
ground check, holding a court hearing, processing the paperwork),

2552 HARVARD LAW REVIEW [Vol. 133:2460
these could very likely be reduced much further if the process were sim-
plified or automated. As an employment intervention, therefore, ex-
pungement appears superior to job training in terms of both its effective-
ness and its price tag.
The arguments of expungement opponents do not typically focus on
program expenditures, of course, but rather on public safety.
345
Fortu-
nately, our findings on the crime front are equally encouraging. Subse-
quent offending rates after expungement are extremely low. Ninety-nine
percent of those who receive expungements in Michigan are not con-
victed of a felony anytime in the next five years; 99.4% are not convicted
of any violent crime; and 95.8% are not convicted of any crime at all,
even a petty misdemeanor. In fact, expungement recipients appear to be
lower risk than the general public. To be sure, recidivism rates would
not be as low if states made expungement available immediately follow-
ing the completion of a sentence, removed judicial discretion, or extended
it to a generally riskier pool, such as people with more extensive criminal
records. But even in those scenarios, there is still no evidence to suggest
that access to expungement would increase the recidivism risk of those
groups; if anything, due to the benefits we find in terms of employment
outcomes (and possible benefits in other areas), one should probably ex-
pect their recidivism rates to decline.
The discouraging element of our findings is that, despite the apparent
benefits of expungement, very few people — even among those who are
eligible — actually obtain them. Our best estimate is that 6.5% of people
who meet the legal requirements for expungement in Michigan obtain
one within five years — a small fraction of what is already a small frac-
tion of all those living with records, given the tight eligibility require-
ments. This low uptake rate is troubling, but not shocking, given the
procedural hurdles and expenses involved, the lack of legal counsel, the
dearth of public information, and the fact that most people with records
have limited resources for overcoming these challenges. Unfortunately,
all but a handful of states with expungement laws require individuals to
apply for relief and give judges the discretion to deny them, so the situa-
tion is unlikely to be better in other states.

2020] EXPUNGEMENT OF CRIMINAL CONVICTIONS 2553
The policy upshot of our research is clear: the process of obtaining
expungement should be made as simple as possible, or ideally automatic
once an individual’s record meets the legal requirements. The path-
breaking Pennsylvania automatic-sealing law, while still at the forefront
of developing legislation, has illustrated a way forward; indeed,
California’s, Utah’s, and New Jersey’s newly adopted automatic ex-
pungement policies are further dramatic advances.
347
With luck, the
next wave of Clean Slate legislation will continue to move in this direc-
tion.
348
Pennsylvania’s law is a watershed in terms of expungement proce-
dure, but it is unfortunately quite limited in its substantive scope (that is,
in terms of its eligibility rules): automatic expungement applies only to
people with minor, nonviolent misdemeanors after ten crime-free
years.
349
Other earlier adopters are less limited on a few dimensions, but
not on many and not by much. Presumably, Pennsylvania clean-slate
advocates concluded that the bill’s substantive constraints were politi-
cally necessary to secure automatic process.
350
Likely, this limitation was
meant to defuse the concern that people with more substantial or more
recent convictions posed a greater public-safety risk. But our findings

orderly records system that transmits records easily from judicial districts to a central office. See

feasible, given that misdemeanor sealing had just been introduced by Act 5 earlier in 2016.” Id. District
attorney support was vital to the passing of the law, leading to more exclusions in the bill: “Critical
stakeholders we needed on board — or at least to remain neutral — were the district attorneys, from
whom opposition on a record-clearing bill in Pennsylvania was likely enough to kill it. One major area
of focus for them and others was which criminal records would be eligible for sealing both through
Clean Slate and through expanded eligibility for filing by petition, and the list of exclusions became
longer as we brought them and other key parties on board.” Id.
2554 HARVARD LAW REVIEW [Vol. 133:2460
indicate that these concerns are unfounded; people who receive expunge-
ments after just five years pose a very low recidivism risk, even though
Michigan does not exclude people with felonies or violent offenses.
351
The somewhat broader approaches now being pursued in states like
California — and perhaps soon in Michigan as well — are more ambi-
tious, and studying their effects will help us to learn more about what
happens when expungement is granted broadly and automatically, and
not to a narrow, self-selected sample.
For now, however, it is likely that most states will continue to require
an application-based, discretionary procedure for at least some subsets of
expungement applicants. Where this is so, policymakers should consider
how to at least render that process as easy and accommodating as possi-
ble. Courts, public defenders’ offices, or prosecutors’ offices could auto-
matically notify individuals, after the requisite waiting period, that they
may be eligible for expungement, and provide them with links to online
tools for determining eligibility. Court hearings should not be necessary,
especially when prosecutors and victims do not oppose expungements.
Online applications should be permitted. Serving the application on mul-
tiple entities (the court, the prosecution, the police) should not be re-
quired, given that the information could be passed along automatically
via computerized processes. Fingerprinting may be essential for back-
ground checks (although this too perhaps could be done via touchscreen),
but there is no reason an applicant should have to make a fingerprinting
visit to a police station and multiple courthouse visits, not to mention a
possible visit to a notary. For example, the court clerk’s office should be
set up to provide whatever records are necessary, provide the form or a
computer terminal, take the fingerprints, and collect the forms all at once.
Fees should be eliminated; they are minor in their impact on the public
fisc (especially given the cost-effectiveness of expungements at improving
employment outcomes), but they remain substantial barriers for many
people with records.
Long after they have served their sentences, tens of millions of
Americans and their families face the serious challenges of life with a
criminal conviction record, and this number increases daily. Collectively,
these challenges contribute to many significant public policy concerns,
making it harder for these families to avoid poverty and contributing to
racial disparities in employment and other domains. Our empirical re-
sults suggest that expungement is a powerful policy lever for redressing
these negative consequences, without risk (and possibly with benefits) to
public safety. But expungement will only realize its full potential and
