# World's Biggest Megacities 2025

Which cities are home to the most people on Earth? 🌆 This fast-paced ranking reveals the planet's 10 most populated megacities and how they stack up against each other.

Tokyo dominates the list with a staggering 37.2 million people, making it the world's largest megacity by a significant margin. But the competition is fierce. Delhi is rapidly closing in on the top spot, signalling a major demographic shift toward South Asian urban centres. Shanghai, Dhaka, and São Paulo complete the top five, each representing different continents and economic powerhouses.

The middle rankings showcase a diverse mix of global giants. Cairo, Mexico City, Beijing, and Mumbai all battle for prominence, reflecting the concentration of population in Asia, Africa, and Latin America. These cities represent vastly different cultures, economies, and urban challenges — from sprawling megacities in developing nations to established metropolitan hubs in developed economies.

What makes this ranking fascinating is the trajectory. While Tokyo has held the crown for decades, projections suggest Delhi could claim the #1 position within the next few years. This shift highlights how population growth patterns are reshaping the global urban landscape, with emerging economies driving unprecedented urbanisation.
