UN: World population to hit 7b in 2012
(Agencies)
Updated: 2009-03-12 10:13 UNITED NATIONS – The world's population will hit 7 billion early in 2012 and top 9 billion in 2050, with the vast majority of the increase coming in the developing countries of Asia and Africa, according to a UN estimate released Wednesday.
Hania Zlotnik, director of the UN Population Division, said that "there have been no big changes" from the previous estimate in 2006. "We are still projecting that by 2050 the population of the world will be around 9.1 billion," she said at a news conference. "The projections are based on the assumption that fertility that is now around 2.56 children per woman is going to decline to about 2.02 children per woman in the world."
Population growth will remain concentrated in the most populous countries through 2050. Nine nations are expected to account for half the projected increase: India, Pakistan, Nigeria, Ethiopia, the US, Congo, Tanzania, China and Bangladesh, the report said. In sharp contrast, the populations of 45 countries or regions are expected to decline at least 10 percent over the same period. Those include Russia, Japan, Italy, South Korea, Cuba, Ukraine and many other countries that were once part of the Soviet Union, the UN said. |
