Every hour, 77 people are added to Lagos.
That's 1,848 per day. 56,000 per month. Roughly the entire population of Greenland arriving every 30 days.
Lagos is the fastest-growing city in Africa and one of the fastest on Earth. Its population has exploded from 325,000 in 1950 to over 17.8 million today — a 55x increase in 76 years.
By 2050, it's projected to reach 36.9 million, making it the 3rd largest city on the planet.
Where are they all coming from?
Strong economic growth — led by Nigeria's oil boom — has pulled the rural poor toward the city for decades. Lagos generates 25% of Nigeria's entire GDP despite occupying less than 0.4% of the country's land. Add high birth rates and the return of Nigerians from abroad, and the result is a city that simply cannot stop growing.
The infrastructure gap is brutal.
Lagos was built for a few hundred thousand people. It now holds 17.8 million. The consequences:
- The road system is nearly paralysed — average commute times in Lagos are among the worst in the world
- Electricity supply is unreliable across most of the city
- Roughly 60-70% of the population lives in informal settlements
- Clean water access remains inconsistent in many neighbourhoods
But there's a different side to the story.
Lagos is also a city of extraordinary energy and enterprise. It has more millionaires than many European capitals. Nollywood — the world's second-largest film industry — is based here. The tech startup scene is among the most dynamic in Africa. And $50 billion in new infrastructure is planned, including a rapid-transit system and Africa's first suspension bridge.
The Africa urbanisation story is just beginning. Africa's urban population is growing at 2.3% per year — the fastest rate in the world. Six Nigerian cities alone rank among Africa's 30 fastest-growing. By 2050, Africa will have added 950 million new urban residents.
Lagos isn't just a city growing fast. It's a preview of what's coming across the continent. The question isn't whether the growth will continue. It's whether the infrastructure can keep up.
Right now, another 77 people just arrived.
