Key Takeaways
- Asia’s urbanization has been the most dramatic globally, with megacities like Shanghai, Delhi, and Jakarta expanding into vast metropolitan regions housing tens of millions.
- Much of Central and mountainous Asia remains sparsely built-up.
- Jakarta and surrounding areas now form one of the world’s largest megacity regions, with more than 30 million residents.
Asia has undergone one of the most significant urban transformations of the last half-century. Cities that were once mid-sized have expanded into megacity regions, with populations rivaling entire countries.
Today, Asia is home to many of the world’s largest metropolitan areas, from Tokyo and Delhi to Shanghai and Dhaka. While coastal corridors and river basins have become densely built-up, large inland regions remain sparsely urbanized, creating a striking contrast across the continent.

Asia Dominates the Global Megacity Rankings
Tokyo remains the world’s largest metropolitan area with more than 37 million people, followed closely by Delhi at roughly 35 million. Shanghai, Dhaka, Beijing, and Mumbai all exceed 20 million residents.

Jakarta and the Rise of Massive Urban Regions
Greater Jakarta now forms one of the world’s largest continuous urban regions, home to over 30 million people. This growth reflects decades of migration toward economic hubs in Indonesia.
Similar patterns appear in China’s Pearl River Delta and across major Indian corridors, where neighboring cities have fused into single metropolitan zones. These megaregions highlight a defining feature of modern Asian development: cities expanding outward until they merge with the next.
The Indo-Gangetic Plain Becomes a Continuous Urban Belt
From Lahore to Dhaka, the Indo-Gangetic Plain has evolved into one of the most densely populated urban corridors on Earth.
Cities like Delhi, Kolkata, Dhaka, and Lahore form a nearly unbroken chain of development supported by fertile land and major river systems. In contrast, mountainous regions such as Tibet, the Himalayas, and Central Asia remain lightly urbanized.
