World population to hit 10.9 billion by 2100

The world’s population will hit 7.2 billion next month and is projected to reach 10.9 billion by 2100, powered by births in poor countries, the United Nations said June 13. With the number of future global dwellers linked to fertility, the number at the end of the century could be as high 16.6 billion or even fall to 6.8 billion, the UN said in its “World Population Prospects.” The population of developing countries is projected to rise from 5.9 billion in 2013 to 8.2 billion in 2050 and 9.6 billion 2100, the report said. The poorest are projected to double in size from 898 million inhabitants of what the report defines as less developed countries this year to 1.8 billion in 2050 and to 2.9 billion in 2100.
