TWO out of every three people will live in cities by 2050, giving rise to the creation of megacities predominantly in China, India and Nigeria, according to a United Nations report released Wednesday. Tokyo will be a fairly second with 36 mn with its population likely to decline a little from 37.3 mn in 2015. Most of this growth is expecting to be concentrated in just a handful of countries.

Elsewhere, countries are considering slicing up their larger cities into more manageable parts.

Not all cities will see growth, the report highlights Nagasaki and Busan, in Japan and South Korea respectively, as having undergone population decline since 2000, as have several cities in eastern Europe. For those surprised that Kozhikode rather than Kochi enters the list from Kerala, here is even more surprising news.

Today, 55% of the world's population is urban, a figure which is expected to grow to 68% by 2050, with the addition of 2.5 billion new city residents, according to projections by the Population Division of the UN Department of Economic and Social Affairs.

The UN study, carried out by the world body's Population Division, predicts that Tokyo's population will start to decline in the coming two years and that it will be surpassed as the world's largest city by New Delhi towards 2028.

Tokyo is now the world's largest city with 37 million people, followed by Delhi with 29 million, Shanghai with 26 million, and Mexico City and São Paulo, each with around 22 million inhabitants.

Cairo, Mumbai, Beijing and Dhaka are all closing in on the 20-million inhabitant mark.




As of 2018, there are 33 megacities and by 2030, 43 megacities are projected, mostly in developing countries. Most of these are located in the low-fertility countries of Asia and Europe where overall population sizes are stagnant or declining.

Delhi will become the world's largest city in a decade, according to the UN. Also, urbanisation will play a huge role as there will be a gradual shift in the residence of the human population from rural to urban areas in Asia and Africa.

The organisation further said: "Many countries will face challenges in meeting the needs of their growing urban populations, including for housing, transportation, energy systems and other infrastructure; as well as for employment and basic services such as education and health care".

"It is projected that India will have added 416 million urban dwellers, China 255 million and Nigeria 189 million." .

The report recommends governments adopt better integrated policies on infrastructure and social services to improve the lives of urban and rural dwellers.

The News Agency of Nigeria (NAN) reports that DESA in earlier report said: "By 2050, the third most populous country will be Nigeria, which now ranks seventh, and which is poised to replace the United States".
