18Lagos, Nigeria

While Lagos is Nigeria’s financial hub and the most populous city in Africa, it’s notorious for its overcrowdedness, high crime rates, and inadequate public services.

Daily life in Lagos involves long traffic jams, unreliable electricity, and limited access to clean water. Its slum areas, where millions of residents live in poverty, face serious challenges related to sanitation, safety, and housing. Corruption within the local administration also hampers efforts to improve the city’s situation.
