Population Reference Bureau: 2016 World Population Data Sheet
PRB has produced its popular World Population Data Sheet 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 estimates the current world population at 7.4 billion and projects an increase to 8.5 billion in 2030 and 9.9 billion in 2050.
“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,” said Jeffrey Jordan, president and CEO of PRB. “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.”
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.
