Nairobi is set to become Africa's largest metropolitan area by 2050, overtaking megacities such as Cairo and Lagos, amid a surge in urbanisation, putting pressure on the capital’s infrastructure, housing and power to provide jobs.
Projections by Africapolis, a research and data visualisation tool developed by the Organisation for Economic Co-operation and Development (OECD), show Nairobi's population will hit 57.2 million by 2050, up from 15.95 million in 2025.
