African Cities
The fastest urbanisation in human history.
Full detail, evidence and debate
Africa is urbanising faster than any region ever has. By 2050 roughly 1.4 billion people — around 60% of Africans — are projected to live in cities, most of whose buildings, pipes and transport lines have not yet been built.
- Urban share 1950
- About 15%
- Urban share 2050
- About 60% (projected)
- Megacities by 2100
- Lagos and Kinshasa among the world's largest
- Informal employment
- Roughly 80% of urban jobs across the continent

Africa's urban record is long and it is indigenous. Jenne-jeno on the Niger inland delta was a functioning city of tens of thousands by the first millennium CE, notable for having no palace, no citadel and no evident central authority — an urban form archaeologists describe as a clustered, heterarchical settlement rather than a capital. Benin City's earthworks, built and maintained over centuries, enclose a length of rampart several times that of the Great Wall of China by some measures; Portuguese visitors in the sixteenth century compared its streets and lighting favourably with Lisbon. Kano's walls, Kilwa's coral-stone town, Aksum, Cairo, Gondar, Great Zimbabwe and the Swahili city-states each solved water, defence, trade and governance in their own way. African urbanism did not begin with colonialism; it was interrupted by it.
The colonial break
Supported by archaeology, written records and peer-reviewed research with broad agreement among historians.
Colonial cities were designed for extraction and control, not habitation. Ports and rail heads were sited to move minerals and cash crops seaward, which is why so many African national road and rail networks still run coastward rather than connecting neighbours. Residential segregation was written into planning law: European quarters with services, African locations without, often separated by a deliberate sanitary cordon justified by malaria theory. Pass laws in South Africa and Southern Rhodesia, and identity and vagrancy rules elsewhere, treated African urban residence as temporary by definition — cities were places to labour in, not to belong to. Independent governments inherited that spatial layout together with the assumption that urban growth was a problem to be reversed, and several spent their first decades trying to send people back to the countryside.
The scale of what is coming
Supported by archaeology, written records and peer-reviewed research with broad agreement among historians.
In 1950 roughly one African in seven lived in a town. By 2050 it will be around three in five, and the absolute numbers are what make the transition historically unusual: something in the order of 900 million additional urban residents within a single lifetime. Lagos, Kinshasa, Cairo, Dar es Salaam, Luanda, Abidjan, Nairobi and Khartoum are all on trajectories that would place several of them among the world's largest cities by 2100. Crucially, most of that growth is not happening in the megacities. Secondary cities of 100,000 to a million people are growing fastest, and they have the least planning capacity, the smallest tax base and almost no access to capital markets — which is where the decisions that will lock in the next century's urban form are actually being taken.
The infrastructure gap
Supported by archaeology, written records and peer-reviewed research with broad agreement among historians.
In most of the world, cities built roads, water, sewerage and power roughly in step with arrival. In Africa, arrival has come first. Somewhere around half of urban Africans live in settlements classified as informal, many without piped water, secure tenure or an address that a utility recognises. The consequences compound: households buy water from vendors at multiples of the utility rate, businesses run diesel generators because the grid is unreliable, and commuting absorbs hours and a large share of income. Kibera in Nairobi, Makoko in Lagos and Khayelitsha in Cape Town are also, however, dense economies with their own landlords, schools, transport and credit systems, and the upgrading programmes that work — in-situ tenure regularisation, incremental servicing, community-led enumeration of the kind Slum Dwellers International pioneered — start from that reality rather than from a bulldozer.
How Africans actually move
Supported by archaeology, written records and peer-reviewed research with broad agreement among historians.
The dominant urban transport system across the continent is privately owned and informally regulated: matatus in Nairobi, danfos in Lagos, trotros in Accra, taxis in Johannesburg, gbaka in Abidjan, plus motorcycle taxis — boda-boda, okada, zemidjan — which have exploded because they navigate congestion and unpaved roads that buses cannot. These networks are efficient at coverage and terrible at safety, emissions and labour conditions. Formal alternatives are arriving unevenly: Addis Ababa's light rail, bus rapid transit in Lagos, Dar es Salaam, Johannesburg and Cairo, and the electric two-wheeler fleets now scaling in Nairobi and Kigali. Digital mapping projects that recorded the matatu network route by route showed planners something they had never had: a map of the system that already worked.
Land, money and who decides
The broad outline is accepted but dates, numbers or details are actively argued by specialists.
Urban land is the deepest structural problem. Customary tenure, colonial-era titles, state ownership and speculative private holdings overlap in the same square kilometre, and where records are paper-based and contested, land disputes clog courts and deter investment. Municipal finance is the second constraint: African cities typically collect a fraction of the property tax they could, depend on central government transfers they do not control, and are rarely creditworthy enough to borrow. Dakar's attempt at a municipal bond and Johannesburg's more successful issuance are the exceptions that show the model is possible. The new-city projects — Eko Atlantic, Konza, Diamniadio, Tatu City — attract the most attention and answer the least of this, since they largely serve the population that already had services.
Climate exposure in the built environment
Supported by archaeology, written records and peer-reviewed research with broad agreement among historians.
African cities carry unusual climate risk because so many of them are coastal, low-lying and built on unprotected ground. Lagos, Alexandria, Abidjan, Dar es Salaam, Maputo and Cotonou face sea-level rise, storm surge and coastal erosion; Accra, Kampala and Durban have experienced lethal flash flooding when drains built for a smaller city met a heavier rainfall regime. Urban heat is compounded by dense corrugated-iron roofing and lost tree cover. The counterweight is that a continent still building most of its urban fabric can build it right the first time — Rwanda's green building code, Kenya's off-grid solar sector, Nairobi's and Cape Town's ecological drainage work and the widespread adoption of stabilised earth blocks and bamboo point to a low-carbon urban path that does not require retrofitting a mistake.
What is at stake
The broad outline is accepted but dates, numbers or details are actively argued by specialists.
How Africa builds this century's cities determines a large share of global emissions in construction materials and transport, the working lives of hundreds of millions of young people, and whether the demographic dividend materialises at all — since cities are where the jobs that dividend requires have to exist. The AU's Agenda 2063 and the New Urban Agenda both treat urbanisation as an asset to be managed rather than a crisis to be contained, which is the right frame. The practical tests are narrow and measurable: does a city government control land records, collect property tax, plan its expansion before people arrive, and give informal residents secure tenure? Where those four are true, African cities improve quickly. Where they are not, growth compounds the deficit.

Lagos
One of the fastest-growing megacities on Earth.
A metropolitan population in the tens of millions, an economy larger than several African countries put together, and a cultural output — film, music, fashion, software — with global reach. Lagos is also a low-lying coastal city built on lagoons and sandbars, growing faster than any authority can plan for, and it has become the place where the arguments about Africa's urban century are settled in practice rather than in theory.
NigeriaThe Youngest Continent
One in four humans will be African by 2050.
Africa's median age is around 19. Its population is projected to reach roughly 2.5 billion by 2050, and by 2100 the continent is expected to hold the world's largest working-age population — an advantage only if it is educated, healthy and employed.
ContinentalAfrica and Climate Change
Least responsible, most exposed, best positioned for what comes next.
Africa produces roughly 4% of global emissions and absorbs some of the sharpest climate impacts — while holding around 60% of the world's best solar resource and a large share of the critical minerals the energy transition needs.
