Global Population Projected to
Reach 11 Billion by 2100, U.N. Estimates
Global fertility rates
The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion by 2050, and 11.2 billion in 2100, according to a United Nations report
released today. The revised U.N. estimates counter previous projections, which had said that global population would peak at roughly 9 billion by 2050, then gradually decline. Most growth will occur in developing regions, the new report says, especially Africa, which is expected to account for more than half of the world’s population growth between 2015 and 2050. India is expected to become the most populous country, surpassing China around 2022. Nigeria could surpass the United States by 2050, which would make it the third-largest country in the world, the U.N. projects. “The concentration of population growth in the poorest countries presents its own set of challenges, making it more difficult to eradicate poverty and inequality,” said John Wilmoth, a director in the U.N.’s Department of Economic and Social Affairs.
