The Urbanisation
Wave
Africa will add 950 million urban residents by 2050 — more than Europe and North America combined. Lagos could reach 88 million by 2100. Fifty cities will exceed 5 million people. Most of the infrastructure for these cities does not exist yet. The largest construction project in human history is about to begin.

001 · The Megacities
Eight cities that will reshape the continent.
Lagos is adding roughly 800,000 people per year. By 2100, projections suggest it could be the world’s largest city at 88 million — larger than any country in Europe. Kinshasa is already larger than Paris and growing at 4% annually. Dar es Salaam is the fastest-growing major city on the continent. Cairo is building an entirely new administrative capital for $58 billion. Inner circles show current population. Outer dashed circles show 2100 projections. The scale of growth is visible in the gap between them.
002 · The Deficit
Cities growing faster than the infrastructure being built for them.
Africa needs 4.5 million new housing units every year. It builds roughly 500,000. Over half of sub-Saharan Africa’s urban population — 256 million people — lives in informal settlements. The deficit is not just housing: it is water, sanitation, power, transport, schools, hospitals. African cities are urbanising at 3.5% annually, the fastest rate globally, but infrastructure investment lags population growth by a decade or more. The opportunity is enormous — McKinsey projects African urban consumers will spend $1.4 trillion by 2030 — but it arrives in cities that are being built and lived in simultaneously.

Urban residents by 2050
Africa will add 950 million urban residents — more than the current populations of Europe and North America combined.
256M
Slum dwellers
Over half of SSA urban population lives in informal settlements. 256M people in slums as of 2020.
56M units
Housing gap
Sub-Saharan Africa needs 56 million new housing units. 4.5M units needed annually. Current production: ~500K.

Up from 7 today. Most infrastructure for these cities does not exist yet. Being built in real time.
003 · The Story
The cities of 2050 are being designed right now. Most of them don’t know it.
The urbanisation wave is the physical expression of every other trend in the Africa progression series. Demographics drive it — a population doubling from 1.4 billion to 2.5 billion means hundreds of millions moving to cities. Energy constrains it — you cannot build a modern city without reliable power. Infrastructure enables it — roads, rail, water, sanitation are the skeleton of urban life. Trade finances it — urban economies need markets.
The scale has no historical precedent. Africa will add more urban residents in the next 25 years than Europe added in the last 200. The cities being built will be among the largest human settlements ever constructed. Lagos at 88 million would be larger than Germany. Kinshasa at 58 million would rival France. Dar es Salaam would go from 8 million to 36 million in a single lifetime. These are not gradual transitions — they are urban explosions happening in real time.
The infrastructure that exists today was largely built for colonial-era populations a fraction of the current size. Lagos was designed for 300,000. Nairobi for 150,000. Kinshasa for 400,000. The gap between design capacity and actual population creates the familiar landscapes of African urbanism: gridlock, informal settlements, overwhelmed utilities, entrepreneurial chaos filling every gap the formal system leaves. What looks like disorder is actually adaptation — millions of people building their own infrastructure because the state cannot keep up.
The opportunity is inversely proportional to the deficit. Every housing unit needed is a construction job. Every road is an engineering contract. Every water system is an infrastructure investment. McKinsey estimates Africa’s urban consumers will spend $1.4 trillion annually by 2030. The question is not whether African cities will grow — that is guaranteed by demography. The question is whether they will grow with planning, infrastructure, and investment, or whether they will grow as they have been: faster than anyone can manage, creating both enormous wealth and enormous hardship in the same neighbourhoods.
Africa will add more urban residents in the next 25 years than Europe added in the last 200. The cities of 2050 are being designed right now.

Roads, rail, ports, power — the skeleton that urban life requires.
Population doubling drives urbanisation. The dividend depends on whether cities create jobs or just crowd.
Modern cities need reliable power. 600M Africans lack electricity. The urbanisation wave meets the energy paradox.
