The rise of African cities.

The fastest urban growth in human history is happening right now, across Africa. Twenty-two of the world's twenty-eight fastest-growing cities are African. The continent's urban population will double to 1.4 billion by 2050 — and the metros, railways and rapid-bus lines being built to move them are one of the defining infrastructure stories of the century.

The continent's giants

Africa already has three megacities of over ten million — and by 2050 it will have seven. Figures vary by where the city boundary is drawn, so these are best read as the scale of the metro region, not a precise headcount.

Growth without precedent

No region has ever urbanised this fast. It is reshaping the map of the world's cities in a single generation.

Africa's cities are growing at about 3.5% every year — the fastest rate on the planet. Lagos alone is projected to add roughly 77 new residents every hour. Kinshasa has already overtaken Paris to become the largest French-speaking city on Earth. Across the continent, more than 60 cities already hold over a million people — on par with Europe — and that number is set to reach 159 by 2050. Eighty percent of Africa's coming population growth will happen in cities, doubling the urban population from 700 million today to 1.4 billion by mid-century.

The fastest, everywhere

Of the 28 cities the UN expects to grow more than 5% a year this decade, 22 are in Africa — led by satellites of Abuja and cities across DR Congo, Angola and Tanzania.

Secondary cities surging

Much of the growth is in mid-sized "secondary" cities of 100,000+ — regionally vital hubs expanding even faster than the megacities themselves.

A young engine

Around 70% of Africans are under 30. Cities are the magnet — drawing young people toward jobs, education and opportunity.

New cities rising

From New Cairo in the desert to purpose-built districts across the continent, governments are building entirely new urban centres to absorb the growth.

Why this is a transit story

Cities this size only work if people can move through them. That is the century's build — and it is already underway.

A city of twenty million cannot run on road traffic alone. The math forces the answer: mass transit. That's why Cairo built Africa's first metro and is now adding driverless monorails; why Lagos opened electric Blue and Red Lines and a unified Cowry Card; why Addis Ababa, Nairobi, Dar es Salaam and dozens more are building light rail and bus rapid transit at pace. The rise of African cities and the rise of African transit are the same story — and mapping it, accurately and currently, is exactly what Met Road exists to do.

By 2050, moving 1.4 billion urban Africans will be one of the largest infrastructure undertakings in human history.

The rails, lines and networks being laid now are the arteries of that future — and the everyday reality for the people already living it.
