Is Nairobi Africa's next global city? The numbers behind the 'New York of Africa' claim
Nairobi produces more than a quarter of Kenya's economy, hosts two UN headquarters and is a 'Beta' world city. But floods, traffic and housing gaps hold it back. Here is the city by the numbers, its strengths and what it still needs.
- World Bank: Africa has about 33 times fewer city planners per person than the UK.
Nairobi is sometimes called the "New York of Africa": a centre for business, diplomacy, technology and culture. It is a catchy line. Here is what the numbers actually say.
Nairobi by the numbers
| Measure | Figure |
|---|---|
| Population (2019 census, city-county) | 4.4 million |
| Metro population (2024 estimate) | About 5.7 million |
| Share of Kenya's GDP | 27.5% (Nairobi County); about 40% for Greater Nairobi |
| Global city rating (GaWC, 2024) | Beta world city |
| UN headquarters | UNEP and UN-Habitat, the only UN global headquarters in the Global South |
| Altitude | 1,795m above sea level |
| Founded | 1899, as a railway depot |
Why people call it a global city
- Diplomacy. With the UN Office at Nairobi, dozens of embassies and regional headquarters, decisions for much of Africa are made here.
- Money and markets. The Nairobi Securities Exchange is Africa's second-oldest stock exchange. Regional banks, insurers and investors are based in the city.
- Tech. Known as the "Silicon Savannah", Nairobi is home to M-Pesa's parent Safaricom, tech hubs and global tech firms' African offices. See Kenya online.
- A unique setting. It is the only capital city with a national park, complete with lions and giraffes, inside its boundaries.
- Big projects. A new JKIA terminal, a 60,000-seat stadium, the NSSF twin towers and a CBD upgrade are changing the skyline.
What still holds it back
- Flooding. Blocked drains and building on riverbanks mean heavy rain quickly floods roads and estates. See the El Niño rains.
- Traffic. Commutes are long, and public transport relies mainly on matatus.
- Housing. Many residents live in informal settlements. The government's affordable housing programme had completed about 13,000 units nationally by October 2026.
- Building safety. The Eastleigh collapse showed gaps in approvals and inspections.
- Services. Water, rubbish collection and revenue collection remain contested issues ahead of the 2027 governor race.
A skills gap behind the skyline
A new World Bank report warns that African cities are growing faster than the professionals who plan them. In 2019, sub-Saharan Africa had about 0.01 urban planners per 1,000 people, compared with 0.33 in the UK, roughly 33 times fewer. It cites a 2015 UN-Habitat review that found the University of Nairobi's urban-planning master's course had changed little since 1971 (the report does not say whether it has been revised since). The bank's point: more planners alone is not enough; training quality has to improve too.
