Theindicatorpercentageofpopulationcoveredbyamobilesignal(2G/3G/4Gandabove)inurbanorruralareasindicatorisbasedon
theindicatorpercentageofthepopulationcoveredbyamobilesignal,whichiscollectedbyITUaspartofalargecollectionof
telecommunicationindicators.Dataarecollectedfromtelecommunicationsoperatorsand,formostcountries,aggregatedatthenational
levelbytelecommunication/ICTregulatorsandMinistrieswhoprovideinformationannuallytoITU.Theindicatoriswidelyavailablefor
bothdevelopedanddevelopingcountries.Dataarealsoavailableforanumberofyears,thusprovidingusefulinformationonassessing
theevolutionofmobilenetworksovertime.
Whilethesplitofthisindicatorintourbanandruralisnotcollectedbymostcountries,thedatawereestimatedbasedontheassumption
thatpopulationsinurbanareasareallcoveredbyamobilesignal.Usingthepercentageofpopulationlivingininurbanareaspublished
bytheWorldBank,the2020dataontheruralpopulationcoveragebymobilesignalwereestimatedbysubtractingtheurbanpopulation
fromthecountry’stotalpopulationcoveredbyamobilecellularsignal.
Finally,the2020dataontheproportionofruralpopulationcoveredbyamobilecellularsignal(2G/3G/4Gandabove)wereestimatedby
dividingthenumberofruralinhabitantswithinrangeofamobilecellularsignalbythetotalruralpopulationandthenmultiplyingby100.
