More than half of the global population growth by 2050 will come from sub-Saharan Africa, where fertility rates will persist at levels far higher than in the rest of the world, the United Nations predictions released on Wednesday show.
As a result, 26 countries in Africa are projected to at least double in size by 2050.
That trend came in spite of lower fertility rates in almost all regions of the world, including in Africa, where rates fell from 5.1 births per woman up to 2005 to 4.7 births in the five years following.
"The population in Africa is notable for its rapid rate of growth, and it is anticipated that over half of global population growth between now and 2050 will take place in that region", he said.
Nigeria, now the world's seventh largest country, has the fastest growing population of the 10 most populous countries worldwide, and the report projects it will surpass the US shortly before mid-century.
A quarter of Europe's population is already aged 60 or over, and that share is projected to reach 35 percent in 2050 then remain around that level for the rest of the century, the report said.
After 2050, India's population is likely to stabilise and begin to decline, going down to 1.5 billion by 2100, according to the report's projection.

"In 2024, both countries are expected to have roughly 1.44 billion", which will be an increase from 1.34 billion people in India now and 1.41 in China, the report said.
In terms of other population trends depicted in the report, the population of India, which now ranks as the second most populous country with 1.3 billion inhabitants, will surpass China's 1.4 billion citizens, by 2024.
The total fertility rate for India, measured as the number of children born to a woman, has fallen from 4.97 during 1975-80 to 2.3 for the current period of 2015-20. "In roughly seven years, the population of India is expected to surpass that of China", said the report, titled "World Population Prospects: The 2017 Revision".
However, the country's fertility rate remains below replacement level pointing to continuing greying of the population and rising dependency rates.
The concentration of global population growth is in the poorest countries, presenting a challenge as the world seeks to implement the 2030 Sustainable Development Agenda, which is aimed to end poverty and preserve the planet, according to the report.
