According to a report by the Institute for Economics and Peace, Surat, Tehran, and London are some of the cities that will be the world’s next megacities by 2050.
The new report from the Institute for Economics & Peace (pdf below) predicts that by 2050, 70 percent of the world’s population—up from 54 percent in 2020—will reside in urban areas. Both population growth and the ongoing urbanisation trend, notably in so-called “megacities”—metropolises with a population of at least 10 million—are contributing to this rise.
Both push and pull factors contribute to urbanisation. The IEA details how issues with violence and a general lack of security, the existence of criminal organisations, a lack of policing, ecological degradation, and the fact that there are too many people for the available agricultural land are all factors driving people away from rural areas in Kinshasa, the capital of the Democratic Republic of the Congo. However, the attraction of a rise in the standard of living may operate as a pull force.
There are 33 megacities in the world right now. The most populous of these are Tokyo (37.3 million), Delhi (32.3 million), Shanghai (28.7 million), Dhaka (22.6 million), So Paulo (22.5 million), and Mexico City (22.1 million). 14 more cities are expected to join them by 2050, bringing the total population increase to 213 million. The new order will then become Delhi (49.6 million), Dhaka (34.6 million), Tokyo (32.6 million), Cairo (32.6 million), and Mumbai (32.4 million).
The populations of these cities will increase, and the economies of the countries will probably expand as well.

By the end of the decade, Bangalore in India and Manila in the Philippines are predicted to have GDP growth rates close to 150 percent.
According to the Pew Research Center, only one region of the world will continue to experience rapid population growth by the end of the century: Africa. All other countries growth rates will begin to slow down. Our chart illustrates this, showing that the highest population growth will be in the African megacities. Only three megacities will experience population declines, including Tokyo (-12%), Osaka (-3%), and the Russian capital, Moscow (-3%) (-12 percent). Tokyo’s population will continue to decline due to an aging population and a dropping birth rate. However, the city will still be the fourth most populated megacity in the world by 2050.
Delhi, Dhaka, Cairo, Tokyo, Mumbai, Shanghai, Kinshasa, Lagos, Karachi, Mexico City, So Paulo, Beijing, Kolkata, New York City, Manila, Lahore, Bangalore, Chongqing, Buenos Aires, Osaka, Hyderabad, Tianjin, Guangzhou, Los Angeles, Rio de Janeiro, Bangkok, Jakarta, Shenzhen, Lima, Paris, and Moscow are among the 33 cities that have already achieved megacity status.
It’s crucial to note that different sources use different statistics in this case and that circumstances can change, especially with forecasts. For instance, the United Nations’ original estimates that India would surpass China as the world’s largest country in 2027 has been revised to April of this year. According to UN data from 2018, a number of more cities, including Wuhan in China and Kuala Lumpur in Malaysia, will tie by 2035 in terms of megacity classification.
