In Asia, population distribution is highly uneven, with the largest concentrations of people historically and currently found in the most fertile agricultural lowlands and river valleys of South and East Asia.12

Key Areas of High Population Density

River Valleys and Plains: The most densely populated areas include the North China Plain, the Yangtze River valley, and the Ganges and Indus river valleys. The Indo-Gangetic Plain and the Ganges-Brahmaputra delta are particularly notable for their high density.13
Coastal Regions: Coastal areas, such as those in Vietnam and the lowlands of Java, have long supported large populations.1
Urban Centers: Increasing urbanization has led to massive population concentrations in major metropolises. Cities such as Guangzhou, Shanghai, Tokyo, Delhi, Jakarta, and Mumbai serve as hubs for millions of people.45

In contrast, mountainous regions—such as the Himalayas—and desert areas, including the Thar Desert, typically have much lower population densities. Similarly, northern Asia remains a lightly populated frontier region.312
