India will take China’s spot as the world’s most populous nation in 2050 with its population projected to increase to 1.6 billion, a new study has revealed.
The French Institute of Demographic Studies (INED) said there would be nearly 10 to 11 billion people in the world by the end of the century from the current 7.1 billion.
INED’s bi-annual report ran parallel to the United Nations’s projection that the global population would swell to 9.6 billion in 2050. The number of people aged 60 and above would balloon to 2 billion in 2050 from the current figure of 841 million, the UN report said.
By 2050, Asia’s population will reach 5.2 billion from 4.3 billion at present, according to Ined, while Africa would be home to 2.5 billion people, or a quarter of the world’s population.
The Americas will breach the one-billion mark in 2050 with 1.2 billion people from 958 million at present.
India is projected to overtake China, the current most populous nation in the world, with 1.3 billion people.
Currently the second most populous nation with 1.2 billion, India is followed by the United States with 316.2 million, Indonesia with 248.5 million and Brazil with 195.5 million.
Nigeria, Africa’s most populous country, will surpass the United States with a population of 444 million against a projected 400 million Americans in the middle of the century.
Fertility rate in Africa remains the highest in the world at 4.8 children per woman, says Gilles Pison, the author of the report.
In contrast, Japan’s low fertility rate will cause the nation’s 127.6 million population in 2012 to drop to just 95 million in 2050.
