Washington D.C., Aug. 25 (ANI
): According to projections included in the latest World Population Data Sheet from the Population Reference Bureau (PRB), the world population will reach 9.9 billion in 2050, up 33 percent from an estimated 7.4 billion now.
The world population would hit the 10 billion mark in 2053 if the assumptions underlying PRB's 2050 projections are applied to subsequent years.
"Despite declines in fertility rates around the world, we expect population gains to remain strong enough to take us toward a global population of 10 billion. Significant regional differences remain, though. For example very low birth rates in Europe will mean population declines there while Africa's population is expected to double," said Jeffrey Jordan, president and CEO of PRB.
PRB's projections show Africa's population will reach 2.5 billion by 2050, while the number of people in the Americas will rise by only 223 million to 1.2 billion.
Asia will gain about 900 million to 5.3 billion, while Europe registers a decline from 740 million to 728 million. Oceania (which includes Australia and New Zealand) would rise from 40 million to 66 million.
PRB's widely referenced Data Sheet has been produced annually since 1962. This year's edition provides the latest data on 19 key population, health, and environment indicators for the world, major regions, and more than 200 countries.
PRB also added six indicators and analytical graphics that explore the balance between providing for human needs and sustainably managing the natural resources on which people depend.
