The global urban landscape is dominated by a handful of megacities, whose immense populations shape culture, drive economies, and influence global migration patterns. According to the latest data from the World Population Review, several of these urban agglomerations have now surpassed the 20 to 30 million resident mark. Here is a detailed look at the ten most populated cities on the planet, with two Indian metropolises securing prominent positions.
The Titans of Population: Top 3 Megacities
Tokyo, Japan, continues to hold the title of the world's most populated city, with a staggering 37 million people calling its metropolitan area home. This vast urban agglomeration serves as Japan's political, financial, and cultural heart. It is renowned for its incredibly efficient public transportation, high-density neighbourhoods, and profound global economic significance, maintaining its top position for years.
In second place is Delhi, India, with an estimated population of 34.67 million. The Indian capital's explosive growth can be attributed to rapid urbanisation, significant migration from other states, and the continuous expansion of its suburban zones into the National Capital Region (NCR). As a major hub for government, business, education, and transportation, Delhi has become one of the largest continuous urban areas worldwide.
Taking the third spot is Shanghai, China, housing approximately 30.48 million residents. As China's primary financial capital, Shanghai is a powerhouse of global trade and business. Its iconic skyline, bustling port, and dense population are direct reflections of its status as a leading economic centre in East Asia.
Global Hubs of People and Power
Dhaka, Bangladesh, follows with a population of 24.65 million, earning its reputation as one of the fastest-growing megacities. This rapid expansion is fueled by large-scale migration from rural areas and its role as the nation's political and economic nucleus, supported significantly by its massive garment industry.
Cairo, Egypt, the sprawling capital on the Nile, is home to around 23.07 million people. It stands as one of Africa's largest and most influential cities, acting as a central hub for the continent's political administration, culture, and economic activities.
In South America, São Paulo, Brazil, makes the list with an estimated 22.99 million residents. Recognised as the economic engine of Brazil, the city's strong industrial and financial sectors continue to attract migrants from across the country and the wider region.
Completing the Top 10 List
Mexico City, Mexico, follows closely with a population of about 22.75 million, making it one of the most populous urban areas in the Western Hemisphere. It is the undeniable centre of Mexico's political, cultural, and economic life.
China makes another appearance with its capital, Beijing, which houses roughly 22.60 million people. As the seat of China's government and a centre for historic sites and a booming tech sector, Beijing's growth mirrors the nation's broader economic ascent.
Mumbai, India, claims the ninth position with an estimated 22.09 million residents. Known as India's financial capital, Mumbai is the heart of the country's finance, media, trade, and entertainment industries. Its coastal location and immense economic opportunities continue to draw people from every corner of India.
Rounding out the top ten is Osaka, Japan. Including its surrounding metropolitan region of Kobe and Kyoto, Osaka has a population of around 19 million. It remains a major commercial and manufacturing hub, known for its vital port activity and strong economic influence within Japan.
This list underscores a significant global trend of urban concentration, with Asian cities, particularly those in India, playing a leading role in this demographic transformation.
