World Bank’s Urban Awakening Reveals Africa’s Uneven Population Boom by 2050

The World Bank projects that Sub-Saharan Africa will gain 748 million urban residents by 2050, taking its urban population to approximately 1.7 billion.

Its October 29, 2026, Sub-Saharan Africa’s Urban Awakening report identifies substantial differences in how that growth will be distributed across the region’s cities and towns.

Luanda is projected to overtake Lagos in population, reaching 20.3 million residents by mid-century. Kinshasa and Dar es Salaam are also expected to expand considerably, while established commercial centres will account for different shares of the region’s urban growth.

The projections point to changes in the relative size of major cities, with implications for the geographical distribution of workers, households and consumer demand.

The World Bank also identifies differences in economic activity and access to employment across urban settlements. Population gains will therefore need to be assessed alongside the locations of businesses and existing commercial networks.

For companies planning long-term expansion, the report’s city-level projections offer an indication of where future labour pools and consumer markets will be concentrated.

Africa’s Fastest-Growing Cities Reshape Urban Population Rankings

Bamako is projected to grow from approximately 4.2 million residents in 2025 to 7.6 million by 2050, an increase of about 81%. The Malian capital would add 3.4 million people, compared with a projected increase of 3.1 million in Onitsha, southeastern Nigeria, where the population is estimated to rise from 5.6 million to 8.7 million.

Mogadishu’s population is projected to reach 7.2 million by mid-century, up from approximately 4.4 million in 2025. That represents growth of nearly 64%, adding another 2.8 million residents to Somalia’s capital.

These projected increases would place greater population concentrations in cities beyond the region’s largest established commercial centres.

Johannesburg presents a different growth pattern. Its population is projected to increase from 7.1 million to 8.9 million, a gain of approximately 25%.

Although the South African metropolitan area would remain a major population centre, its growth rate would be substantially below those projected for Bamako and Mogadishu.

Kinshasa and Dar es Salaam are also important to the region’s changing urban population distribution. Their positions in the 2050 rankings require comparable city-level estimates, using consistent geographical boundaries.

The available projections show that several secondary and capital cities are gaining residents at different rates, with absolute population increases and percentage growth producing different measures of urban expansion.

Urban Expansion Pushes African Cities Beyond Existing Boundaries

Sub-Saharan Africa’s urban footprint is projected to expand by approximately 90% by 2050, with nearly half the urban space required by mid-century yet to be developed.

Much of the additional settlement area will emerge around existing cities, extending residential development beyond today’s built-up boundaries.

The World Bank identifies metropolitan outskirts as an important part of the region’s urban expansion. Land surrounding established cities provides space for new housing and commercial development, while population growth within existing neighbourhoods increases residential density. The balance between these forms of growth will differ across metropolitan areas.

Peripheral settlements are not necessarily separate towns. As development spreads, formerly rural land can become part of a larger continuous urban area, changing the distribution of residents without altering the population of the wider metropolitan region. Administrative city boundaries and the physical extent of development may therefore describe different areas.

For businesses assessing future labour and consumer markets, these distinctions affect where population growth will be recorded and where residents will live. City-centre population figures alone will not capture the full extent of settlement growth around Africa’s expanding metropolitan areas.

Africa’s Smaller Towns Face Uneven Economic Growth Prospects

The World Bank identifies more than 15,000 towns across Sub-Saharan Africa, many outside the region’s largest metropolitan areas. Their locations vary considerably, from settlements near established commercial centres to towns separated from major transport routes and markets.

Towns situated along economic corridors have access to trade routes connecting larger cities and production centres. Those near metropolitan areas can also serve businesses and workers operating across adjoining settlements. The Bank identifies geographical access to economic activity as an important factor in assessing their development prospects.

More isolated towns face different conditions. Greater distances from commercial centres restrict access to larger customer markets and employment opportunities. Local economic activity is consequently more dependent on businesses and services operating within the surrounding area.

The report distinguishes between towns with access to established economic networks and those where opportunities remain limited. These differences are relevant to the distribution of Africa’s future urban population, particularly as smaller settlements accommodate residents outside the continent’s principal metropolitan centres.

Africa’s Population Boom Confronts Uneven Urban Productivity

Sub-Saharan African cities generate nearly 50% less economic activity, measured by nighttime lights, than similarly sized cities at the global frontier, according to the World Bank. The difference shows how far economic output varies between urban centres with comparable populations.

The Bank also finds that urban households spend more per adult than rural households with similar education levels. However, purchasing power differs across cities according to employment opportunities, earnings and access to commercial activity. Larger populations do not necessarily translate into equivalent consumer spending.

Transport restrictions affect access to employment. Approximately 25% of firms identify transportation as a major or very severe obstacle, while only 32% of Africans live within walking distance of public transport. The location of jobs relative to residential areas therefore affects the number of workers businesses can realistically recruit.


About 15 million young people enter Sub-Saharan Africa’s labour markets annually. Their employment prospects will depend on the capacity of growing cities and towns to support productive businesses and provide access to work.

The World Bank’s projections identify where urban populations are expected to expand, while differences in employment and economic activity will influence which centres develop into larger commercial markets.
