forȱAfrica.ȱȱ Africa’sȱ urbanȱ growthȱ isȱ inȱ lineȱ withȱ theȱ trendsȱ observedȱ inȱ mostȱ emergingȱ andȱ developedȱ countries.ȱ Inȱ theȱ lastȱ 10ȱ years,ȱ theȱ region’sȱ economiesȱ grewȱ rapidly—aboveȱ 5ȱ percentȱ aȱ yearȱ (IMFȱ 2012)—andȱ theȱ outlookȱ forȱ theȱ nearȱ termȱ isȱ largelyȱ positive.ȱ Findingsȱ fromȱ economicȱ geographyȱ tellȱ usȱ thatȱ densityȱ isȱ neededȱ forȱ economicȱ prosperityȱ andȱ thatȱ urbanȱ growthȱ isȱ aȱ necessaryȱ conditionȱ forȱ acceleratedȱ growthȱ andȱ sharedȱ prosperityȱ (Worldȱ Bankȱ 2008;ȱ Hendersonȱ 2005,ȱ 2010;ȱ Venablesȱ 2010).ȱLongȬrunȱgrowthȱneedsȱanȱefficientȱsystemȱofȱurbanȱcentersȱthatȱ produceȱ industrialȱ goodsȱ andȱ highȬvalueȱ services,ȱ alongȱ withȱ transportationȱ networksȱ toȱ linkȱ nationalȱ economiesȱ withȱ regionalȱ andȱ globalȱmarketsȱ(Spenceȱetȱal.ȱ2009;ȱWorldȱBankȱ2009).ȱȱ Alongȱ theȱ broadȱ spectrumȱ ofȱ developmentȱ patterns,ȱ Africaȱ

characteristics.ȱ Althoughȱ Africaȱ andȱ Asiaȱ haveȱ similarȱ urbanȱ ratesȱ(aroundȱ40ȱpercent),ȱperȱcapitaȱGDPȱinȱAfricaȱwasȱoneȱthirdȱthatȱofȱ Asianȱ countriesȱ inȱ 2012.ȱ Inȱ addition,ȱ Africa’sȱ literacyȱ ratesȱ andȱ institutionalȱ developmentȱ indicesȱ areȱ muchȱ lowerȱ thanȱ Asianȱ counterparts,ȱandȱAfrica’sȱinfrastructureȱlagsȱbehind.ȱȱ Recentȱpopulationȱcensusesȱareȱ providingȱmoreȱaccurateȱdataȱthanȱ hasȱbeenȱavailableȱinȱtheȱpast.ȱAmongȱotherȱissues,ȱthisȱnewȱinformationȱ willȱ shedȱ lightȱ onȱ suchȱ questionsȱ asȱ (a)ȱ theȱ sizeȱ andȱ sourceȱ ofȱ urbanȱ growthȱ acrossȱ Africanȱ countriesȱ (Pottsȱ 2012;ȱ Gollinȱ etȱ al.ȱ 2013);ȱ (b)ȱ theȱ roleȱ ofȱ ruralȱ migrationȱ versusȱ naturalȱ growthȱ inn ȱ urba ȱ expansionȱ (Foxȱ 2012);ȱ andȱ (c)ȱ theȱ usefulnessȱ ofȱ growthȱ modelsȱ inȱ explainingȱ theȱ longȬ termȱ patternȱ ofȱ urbanization.ȱ Theȱ typicalȱ modelsȱ ofȱ structuralȱ transformationȱexplainȱurbanȱexpansionȱthroughȱtheȱmovementȱofȱlaborȱ fromȱruralȱtoȱurbanȱareasȱthatȱfollowȱtheȱtransformationȱfromȱagricultureȱ toȱ industryȱ andȱ services.ȱ Urbanizationȱ wouldȱ beȱ aȱ resultȱ ofȱ eitherȱ aȱ “push”ȱfromȱagriculturalȱproductivityȱgrowthȱorȱaȱ“pull”ȱfromȱindustrialȱ productivityȱ growthȱ leadingȱ toȱ “productionȱ cities,”ȱ withȱ aȱ mixȱ ofȱ workersȱinȱtradableȱandȱnonȬtradableȱsectors.ȱȱ However,ȱthisȱmodelȱofȱdevelopmentȱdoesȱnotȱseemȱtoȱexplainȱtheȱ urbanizationȱ patternȱ ofȱ moreȱ thanȱ aȱ dozenȱ Africanȱ countries—thoseȱ whoseȱ economicȱ growthȱ hasȱ beenȱ associatedȱ withȱ naturalȱ resourceȱ exploitationȱ butȱ notȱ withȱ increasedȱ manufacturingȱ sharesȱ ofȱ GDPȱ (Collierȱ2009;ȱGollinȱetȱal.ȱ2013).ȱInȱtheseȱcountries,ȱurbanizationȱisȱlikelyȱ toȱ haveȱ beenȱ drivenȱ byȱ theȱ incomeȱ effectȱ ofȱ naturalȱ resourceȱ endowments.ȱ Assumingȱ thatȱ tradableȱ goodsȱ areȱ more ȱ likelyȱ associatedȱ withȱ increasesȱ inȱ productivityȱ thanȱ nonȬtradableȱ goods,ȱ theȱ lackȱ ofȱ manufacturingȱ developmentȱ couldȱ hinderȱ longȬrunȱ economicȱ potentialȱ forȱAfricanȱcities.ȱThisȱargumentȱmeritsȱfurtherȱempiricalȱresearch.ȱȱ Understandingȱ Africanȱ urbanizationȱ isȱ highlyȱ relevantȱ inȱ otherȱ domainsȱ asȱ well.ȱ Extremeȱ povertyȱ continuesȱ toȱ beȱ moreȱ prominentȱ inȱ ruralȱ thanȱ inȱ urbanȱ areasȱ (atȱ leastȱ threeȱ timesȱ higher).ȱ Therefore,ȱ urbanizationȱwouldȱseemȱtoȱbeȱaȱsuperiorȱwayȱtoȱprovideȱbetterȱservicesȱ andȱ livelihoodsȱ toȱ millions,ȱ asȱ wellȱ illustratedȱ inȱ theȱ caseȱ ofȱ Chinaȱ (Taylorȱ 2008).ȱ Oneȱ mayȱ expectȱ thatȱ overȱ time,ȱ theȱ gapȱ betweenȱ urbanȱ andȱ ruralȱ earningsȱ willȱ declineȱ andȱ eventuallyȱ disappear,ȱ asȱ surplusȱ laborȱ shrinksȱ andȱ theȱ ruralȱ sectorȱ modernizes.ȱ Butȱ itȱ beȱ quiteȱ aȱ whileȱ 2 Maria Freire, Somik Lall, and Danny Leipzigerȱ untilȱthisȱoccurs.2ȱAsȱpartȱofȱtheȱprocess,ȱoneȱmightȱstressȱtheȱimportanceȱ ofȱ governmentsȱ providingȱ basicȱ servicesȱ toȱ smallerȱ citiesȱ andȱ intermediateȱ townsȱ thatȱ canȱ facilitateȱ theȱ transitionȱ betweenȱ ruralȱ andȱ nonȬruralȱ activitiesȱ (Ferreȱ etȱ al.ȱ 2010),ȱ theȱ
