UNITED NATIONS, United States (AFP) — Sixty-eight per cent of the world's population will live in urban areas by the year 2050, the United Nation said Wednesday, up from 55 per cent at present.

The UN report predicted an extra 2.5 billion people living in ever-expanding cities in the next 30 years, with as much as 90 per cent of the urban growth centred on Asia and Africa.

The boom in city-dwellers will be concentrated in certain countries, with 35 per cent of urban expansion occurring in India, China and Nigeria alone between 2018 and 2050.

That will add up to an extra 416 people in towns and cities in India, 255 million in China and 189 million in Nigeria.

The number of people living in urban areas worldwide has risen rapidly from 751 million in 1950 to 4.2 billion in 2018. Despite its lower rate of urbanization, Asia contains 54 per cent of all urban residents in the world, followed by Europe and Africa with 13 per cent each.

The general migration from rural to urban areas, combined with overall population growth, will lead to the planet having 43 megacities by 2030, each home to more than 10 million people.

Tokyo is currently the largest city on the planet with 37 million inhabitants, followed by New Delhi with 29 million, Shanghai with 26 million and Sao Paulo and Mexico City with 22 million apiece.

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

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.
