More people, more cities: Africa’s demographic development (2017)

In our ima­gi­na­ti­on, Afri­ca may still be a con­ti­nent with a domi­nant­ly rural popu­la­ti­on and vast untouch­ed are­as of forest and savan­na. But the geo­gra­phi­cal space that is Afri­ca will be more and more urban. Let’s look at some figu­res and pro­jec­tions, most­ly taken from a stu­dy of the OECD published in 2017.

In our ima­gi­na­ti­on, Afri­ca may still be a con­ti­nent with a domi­nant­ly rural popu­la­ti­on and vast untouch­ed are­as of forest and savan­na. But the geo­gra­phi­cal space that is Afri­ca will be more and more urban. Let’s look at some figu­res and pro­jec­tions, most­ly taken from a stu­dy of the OECD published in 2017.[i]

Rapid growth and urba­nizati­on

Africa’s popu­la­ti­on is gro­wing rapidly—so rapid­ly that by 2050, one in three young peo­p­le (aged 15–29) will live in Afri­ca. And by 2100, the Afri­can con­ti­nent will be home to 40% of the world’s popu­la­ti­on.

At the same time, urba­nizati­on is pro­gres­sing rapid­ly — well over a bil­li­on peo­p­le (56%) will live in cities in 2050, com­pared to less than 500 mil­li­on (41%) today. By 2030, Afri­ca will have 95 cities with over a mil­li­on inha­bi­tants.

A clo­ser look at West Afri­ca

How this deve­lo­p­ment plays out, will vary a lot in the dif­fe­rent Afri­can regi­ons. Geo­gra­phy and spa­ti­al inter­ac­tions will be a key fac­tor in the ana­ly­sis of the­se urba­nizati­on pro­ces­ses. If we look at West Afri­ca, for exam­p­le, which has been the focus of the OECD stu­dy, the acce­le­ra­ting speed of urba­nizati­on is con­firm­ed. In 1950, just 5 mil­li­on peo­p­le lived in cities[ii] in West Afri­ca. By 2010, this figu­re had risen to 133 mil­li­on, spread across 1,939 cities. Of the­se, more than a quar­ter (566) were estab­lished bet­ween 2001 and 2010.

Thus, we look at a future of a West Afri­can mega­lo­po­lis with seve­ral hundred mil­li­on inha­bi­tants along a 2,000-kilometer cor­ri­dor bet­ween Abi­djan in the west, Lagos in the midd­le, and Dou­a­la in the east.

Urba­nizati­on – a boon or a bur­den?

This is an enorm­ous chall­enge. Can sta­tes and muni­ci­pa­li­ties keep up, at least to some ext­ent, with the needs for plan­ning, infras­truc­tu­re deve­lo­p­ment and its finan­cing? And what will be the impact on the demo­gra­phy its­elf? Some demo­graph­ers con­sider urba­nizati­on as an important fac­tor in demo­gra­phic tran­si­ti­on, that is the tran­si­ti­on to lower fer­ti­li­ty rates: access to edu­ca­ti­on, eco­no­mic oppor­tu­ni­ties, smal­ler fami­lies.

Howe­ver, avera­ge inco­mes in Afri­can cities remain very low, and endo­ge­nous popu­la­ti­on growth is high. The­r­e­fo­re, the­re is ano­ther view that Afri­ca is urba­ni­zing while remai­ning poor (this was the fin­ding of the World Bank in a report published in 2017). We don’t know – both rea­li­ties are likely, depen­ding in regi­on, loca­ti­on and eco­no­mic resour­ces, and cons­trai­ned by a gene­ral lack of resour­ces for tru­ly sus­tainable urban deve­lo­p­ment.
