Top 10 Largest Cities in the World by Population in 2025

By 2025, the global population is projected to reach 8.2 billion, with rapid urbanisation leading to the growth of megacities across Asia, Africa, and Latin America. India, which overtook China in 2023, is now the world’s most populous country with 1.42 billion people. Urban hubs are absorbing more residents than ever, and cities like Tokyo, Delhi, and Shanghai dominate the global rankings.

Asia leads the list with India, China, Bangladesh, and Japan contributing multiple megacities.

Africa’s Cairo is one of the fastest-growing cities, reflecting strong demographic expansion.
