These Are The World's 5 Largest Megacities
By 2050, 68% of the global population is projected to live in urban centers, up from 55% today.
The world’s largest megacity, when measured by the combination of satellite imagery and census data, is Guangzhou, China.
Strikingly, the population has boomed by nearly 20-fold in just 50 years driven by China’s rapid economic rise.
This graphic, via Visual Capitalist's Dorothy Neufeld, shows the growth of the world’s megacities, based on data from the European Commission via Our World in Data.
Below, we show the rise of the top five largest cities worldwide—using satellite imagery and census data—not administrative borders:
Since 1975, the population of Guangzhou has expanded by 40.9 million. It has the equivalent population of the entire country of Canada.
During the 1990s, the city’s population growth accelerated, driven by trade and industrial activity. Located on the Pearl River Delta, north of Hong Kong, it stands as a key port and transportation hub.
Jakarta, Indonesia’s capital and the economic hub of Southeast Asia’s largest economy, has undergone massive expansion. Its population has surged by 29 million over the past five decades, reaching 38.1 million today.
Meanwhile, New Delhi, India has grown 398%, supported by rising incomes and urban migration. By 2030, the city is expected to gain nearly two million more residents, spanning a population of 33.3 million.
