UNITED NATIONS (AP) — The world's population will likely reach 9.2 billion in 2050, with virtually all new growth occurring in the developing world, a U.N. report said Tuesday.
According to the U.N. Population Division's 2006 estimate, the world's population will likely increase by 2.5 billion people over the next 43 years from the current 6.7 billion — a rise equivalent to the number of people in the world in 1950.

Hania Zlotnik, the division's director, said an important change in the new population estimate is a decrease in expected deaths from AIDS because of the rising use of anti-retroviral drugs and a downward revision of the prevalence of the disease in some countries.

The new report estimates 32 million fewer deaths from AIDS during the 2005-2020 period in the 62 most affected countries, compared with the previous U.N. estimate in 2004.

This change contributed to the slightly higher world population estimate of 9.2 billion in 2050 than the 9.1 billion figure in the 2004 estimate, the report said.
