ASIATODAY.ID, JAKARTA — Asia is entering the most decisive demographic phase in modern history.
Home to more than half of the world’s population, the continent is not only adding millions of people each year but is also accelerating toward an era of extreme urbanization—a transformation that could redefine global economic growth, social stability, and climate resilience.
New Worldometer 2026 data confirms a historic shift: India has officially surpassed China as the world’s most populous country, while Indonesia remains firmly in third place. At the same time, the United Nations warns that nearly half of humanity now lives in cities—with Asia at the center of the global urban explosion.
India Surpasses China, Indonesia Holds the Third Spot
According to Worldometer’s 2026 population projections, Asia’s demographic hierarchy is undergoing a dramatic realignment:
India: 1.476 billion (+0.87%)
China: 1.412 billion (−0.22%)
Indonesia: 287.8 million (+0.76%)
India is not only larger in absolute terms but continues to grow by more than 12.7 million people annually, while China is losing over 3 million people per year, driven by aging, low fertility, and shrinking birth cohorts.
Indonesia, with a fertility rate of 2.1 and an urban population exceeding 60 percent, now stands at a demographic crossroads—poised between a prolonged demographic dividend or mounting social and infrastructural strain.
South and Southeast Asia Drive Global Population Growth
Population momentum remains strongest across South and Southeast Asia:
Pakistan: 259 million (+1.6%)
Bangladesh: 177 million (+1.21%)
Philippines: 117 million
Vietnam: 102 million
In contrast, much of East Asia faces a demographic slowdown. Japan, South Korea, Taiwan, and China are all recording population decline, driven by ultra-low fertility rates and rapidly aging societies.
Half of Humanity Now Lives in Cities
This demographic surge is inseparable from a larger structural shift: rapid global urbanization.
According to the UN World Urbanization Prospects 2025, released by the UN Department of Economic and Social Affairs (UNDESA), around 45 percent of the world’s 8.2 billion people now reside in urban areas—a share that continues to rise sharply.
“Urbanization is a defining force of our era. When managed inclusively and strategically, it can unlock transformative pathways for climate action, economic growth, and social equity,” said Li Junhua, UN Under-Secretary-General for Economic and Social Affairs, in November 2025.
Jakarta Emerges as the World’s Largest City
The UN report highlights a fourfold increase in megacities—urban areas with more than 10 million residents—since 1975:
– 8 megacities in 1975
– 33 megacities in 2025
– 19 of them located in Asia
At the top of the list stands Jakarta, now recognized as the largest metropolitan area on the planet, with nearly 42 million inhabitants, surpassing Dhaka and Tokyo.
Top global megacities:
Jakarta, Indonesia
Dhaka, Bangladesh
Tokyo, Japan
Notably, Cairo is the only non-Asian city to appear in the global top ten.
By 2050, the number of megacities is projected to rise to 37, with cities such as Kuala Lumpur, Addis Ababa, Dar es Salaam, and Hajipur expected to cross the 10-million threshold.
Small Cities, Not Megacities, Are Growing the Fastest
Despite the global focus on megacities, UNDESA finds that small and medium-sized cities are expanding at a far faster rate—especially across Asia and Africa.
From an analysis of more than 12,000 cities worldwide:
– 96% have fewer than 1 million residents
– 81% have fewer than 250,000 residents
– The total number of cities has more than doubled since 1975
By 2050, the global urban count could exceed 15,000 cities, driven largely by smaller urban centers that often lack adequate infrastructure, planning capacity, and climate resilience.
A Demographic Paradox: Growing Nations, Shrinking Cities
The UN report also identifies a striking paradox:
– Some cities are shrinking even as national populations grow
– Others continue to expand despite overall population decline
More than one-third of shrinking cities are located in China, with India accounting for 17 percent. Even major urban centers such as Chengdu and Mexico City are now experiencing population losses.
Rural Areas in Retreat—Except in Africa
Globally, rural populations are rapidly diminishing:
– In 1975, rural areas dominated in 116 countries
– Today, that number has fallen to 62
– By 2050, it is projected to decline further to 44 countries
Sub-Saharan Africa remains the only region expected to see continued rural population growth, while Asia accelerates toward near-total urban dominance.
Asia at a Historic Crossroads
The convergence of population growth and urban expansion places Asia at the epicenter of the world’s future—as both a potential engine of innovation and a flashpoint for inequality, environmental stress, and climate risk.
For Indonesia and the broader Asian region, the question is no longer whether cities will grow, but whether governments can manage people, space, and ecosystems at a scale unprecedented in human history. (AT Network)
