Recent reports reveal Jakarta has become the world's most populous city, surpassing Tokyo with a population of 42 million. This dramatic shift highlights the rapid urban growth happening across Asia, driven by migration, environmental factors, and changing methodologies in population estimates. Curious about what’s fueling this urban transformation? Below, we explore the key reasons behind Jakarta's rise and what it means for future megacities.
-
Why did Jakarta overtake Tokyo as the most populous city?
Jakarta's population growth is mainly due to rural migration, urban sprawl, and environmental challenges like flooding and sinking land. Changes in how the UN estimates city populations also played a role, revealing Jakarta's rapid expansion that was previously underestimated.
-
What factors are driving rapid urban growth in Asia?
Asia's urban growth is driven by rural-to-urban migration, economic opportunities, and population increases in developing countries. Climate change and environmental pressures are also pushing people toward cities, especially in countries like Indonesia and Bangladesh.
-
Will Dhaka become the largest city by 2050?
Yes, projections suggest Dhaka could become the world's largest city by 2050 due to high birth rates, rural migration, and limited urban infrastructure. Its rapid growth reflects broader trends of megacity development in South Asia.
-
How do climate change and migration influence city populations?
Climate change causes environmental issues like flooding and land sinking, prompting migration from affected areas. Many people move to cities seeking safety and better economic prospects, fueling urban population growth and creating new challenges for infrastructure and sustainability.

What are the environmental challenges of rapid urbanization?
Rapid urban growth often leads to environmental problems such as pollution, deforestation, and sinking land. Cities like Jakarta are also facing climate-related issues like flooding, which threaten their sustainability and require innovative solutions.
