10 most populated cities in the world; 2 Indian cities make the cut

With the world moving more and more towards urbanization, mega-cities control significant economic power, culture and population. By 2025, the ranking of the globe's top cities will take into account not just rising birthrates but also urbanizing refugee populations, exurban settlements and metropolitan growth. This data is as per World Population Review.
Here’s a look at the top 10 most populated cities in the world in 2025—urban mammoths where millions live, work, commute, and create the future of humanity every single day.

With this much population, Tokyo tops the list. More famous for its unparalleled mixture of tradition meets innovation, the greater Tokyo metro area is a city where transport logistics are second to none; housing can be cramped, but it is orderly and systematic in function like Japan itself, and above all, work culture abides by Japanese discipline.

Delhi, whose population has exploded over the past both decades, following hot on Tokyo's heels. Booming population growth has been accompanied by strains, as pollution, traffic congestion and stresses on public services attest.

Shanghai is China’s economic juggernaut and its most populous city in 2025. A global financial center, it boasts some of the world’s most impressive skylines and urban infrastructure. While growth has steadied in recent years, migration from inner provinces continues to push the numbers higher.

One of the fastest-growing cities on the planet, Dhaka is an urban explosion. Its population has ballooned due to rural migration, with people drawn by job opportunities in the garment industry and informal sector. The city grapples with housing shortages, waterlogging, and transportation chaos—but remains the beating heart of Bangladesh’s economy and politics.

Cairo, the largest city in Egypt combines ancient civilization with modern sprawl; still growing as its population increasingly swells. But the city is feeling the strain: congestion, pollution and a housing crisis are rife. In Egypt, the government is even constructing a brand-new administration capital to lighten Cairo.

Sao Paulo, although recognized for its skyscrapers and art scenes, the city has also a notorious reputation for traffic jams and wealth disparity. São Paulo, with almost 23 million inhabitants in its metropolitan area, is still a Latin American city that grows and grows.

Mexico City, once the world’s largest urban area,continues to be a dynamic and densely packed metropolis. Nestled in a high-altitude valley, it juggles ancient Aztec history with modern-day sprawl. The metro area’s population keeps growing, albeit more slowly now, and its geographic constraints make expansion a continual challenge.

The political heart of China, Beijing is a city of contrasts, imperial palaces, hyper-modern infrastructure, and booming tech districts. Though second to Shanghai in population, it plays an outsized role in governance, innovation, and cultural identity.

Mumbai remains India’s financial capital, a city of extreme contrasts where billionaires live beside sprawling slums. With over 22 million residents, its vertical growth has been essential, but pressure on housing, transport, and sanitation is unrelenting. Yet Mumbai’s spirit, fast pace, and Bollywood dreams continue to attract people from across the country.

Completing the top 10 is Osaka, another Japanese powerhouse. While Tokyo often gets the spotlight, Osaka is a massive economic and cultural hub in its own right. Known for its street food, commercial centers, and easygoing charm, it still maintains a high population despite Japan’s overall demographic slowdown.
