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.
