African Cities: The Next Frontier of Global Growth

The center of gravity of global economic growth is quietly shifting southward. This year, the African continent will surpass Asia to become the world's fastest-growing region—a trend unlikely to reverse in the foreseeable future, as demographic momentum slows elsewhere. For investors, policymakers, and multinational corporations, the instinct is to ask which countries will lead this rise. However, that may be the wrong question: the true engine of Africa's economic transformation will be its cities.

This is not new. Throughout history, great cities have stood at the center of national and continental prosperity. Manchester drove industrial Britain, New York anchored global finance, and Shenzhen powered China's rise. But in Africa, this dynamic will unfold on an entirely different scale. The continent is already urbanizing at an unprecedented pace and scale. By mid-century, it will also be the only region with a growing working-age population. Few other forces will shape the 21st-century global economy as profoundly.

Yet not long ago, Africa's megacities were viewed with anxiety rather than optimism—swelling populations were thought to overwhelm weak institutions, disrupt social order, and herald broader chaos. My city, Lagos, was once seen as the epitome. In 1994, writer Robert Kaplan famously described it in his article as "a prime example of a Third World city's dysfunction."

History did not unfold as predicted. Military rule once allowed dysfunction to pile up. But when uniforms gave way to the ballot box in 1999, determined reformers—spurred by democracy and public support—began the long work of rebuilding order from years of neglect.

Today, Lagos is Africa's largest city. If it were an independent economy, its size would rank fifth on the continent—ahead of Kenya. Dealroom recently ranked Lagos as one of the world's top emerging tech ecosystems. It is home to about two-thirds of Africa's unicorns. The city is still restless, occasionally chaotic, but in many ways, this is inseparable from the unique energy that drives its economic vitality and capacity for reinvention—qualities that have long defined the world's great commercial cities.

It is in cities like Lagos that Africa's demographic dividend must be captured. The same phenomenon once transformed Asia—when the number of workers far exceeded children and the elderly. But a demographic wave rises only once in a nation's life. Once it recedes, the challenges common to developed countries—aging, rising dependency ratios, slower growth—become inevitable. History will not forgive those who miss the opportunity.Scale alone does not bring prosperity. Without opportunity, a population advantage can turn into frustration. Africa cannot afford a future where youthful energy is blocked by economic exclusion. However, neither national governments nor city governments create jobs; businesses do. The task of government is to focus on giving urban scale economic momentum: connectivity — connecting talent with opportunity, ideas with capital, and businesses with suppliers and markets. In practice, this means reducing congestion in transportation networks, planning for density rather than sprawl to allow efficient clustering of businesses and workers, and digital and physical infrastructure that reduces the friction of doing business. This is how cities become engines of productivity and prosperity.

The urgency is pressing. By 2050, Africa's cities will absorb about 900 million new residents — the equivalent of adding the total urban population of Europe and America in just one generation. If urbanization outpaces governance, it could revive past anxieties about African urbanization. Yet opportunities grow alongside challenges. The African Continental Free Trade Area — bringing together 54 countries into the largest free trade area by population — will only expand the economic horizons of its cities. No longer limited by domestic demand, they will increasingly serve regional and continental markets — supporting deeper specialization, stronger supply chains, and more complex service economies.

The next phase of Africa’s growth will no longer be purely national, but urban. The question is no longer who will rise, but which cities can organize themselves most effectively to lead the process.
