Lagos, the sprawling Nigerian mega-city, is on track to become the first city on Earth to reach 100 million residents by 2100, according to researchers from Ontario Tech University. The prediction, made by Daniel Hoornweg and Kevin Pope, highlights the city's explosive growth, which adds more than 600,000 people each year.
Current Population and Growth Rate
International estimates place Lagos's population at around 17.8 million in 2026, though local officials believe the true figure may already exceed 22 million. The city's population is increasing by approximately 4% annually, driven by high birth rates and massive inward migration. Lagos is widely regarded as the economic heart of Nigeria and much of West Africa, attracting people seeking work, education, and opportunities.
Challenges of Rapid Urbanization
This rapid growth brings significant challenges. Traffic congestion is a daily ordeal for residents, and housing shortages have led to the expansion of large informal settlements. Flooding is a persistent concern, as Lagos sits on the coast and is surrounded by lagoons and waterways. These issues are compounded by the city's young population, which fuels further growth.
Infrastructure Projects and Future Planning
Authorities are undertaking major infrastructure projects to prepare for the future. The Lagos Rail Mass Transit system is being expanded, and investments are being made in new roads, bridges, and ferry routes. Large-scale developments like Eko Atlantic are creating new space for homes, businesses, and investment. These efforts aim to manage the pressures of becoming the world's first 100-million-resident city.
Global Context
The United Nations projects the global population will rise from 8.3 billion today to about 10.3 billion by the mid-2080s before gradually declining. Lagos's trajectory reflects broader trends of urbanization in Africa, where cities are growing faster than anywhere else on the planet. While some recent studies suggest slightly lower figures, most experts agree that Lagos will likely become the world's largest metropolitan area by the end of the century.
