United Nations: India, China and Brazil countries with young populations but lower fertility face the prospect of substantial population ageing before the end of the century, according to UN projections.
The world’s population will increase from today’s 7.3 billion people to 9.7 billion in 2050 and 11.2 billion at century’s end, UN Population Division director John Wilmoth told a session focused on demographic forecasting at the 2015 Joint Statistical Meetings (JSM 2015) in Seattle on Tuesday.
The UN projection suggests there will not be an end to world population growth this century unless there are unprecedented fertility declines in those parts of sub-Saharan Africa that are still experiencing rapid population growth. The UN estimated the probability that world population growth will end within this century to be 23%.
