The world’s population is expected to shrink in the second half of the 21st century, according to researchers.
The research, which is published in The Lancet medical journal, forecasts mortality, fertility and migration for 195 countries worldwide.
The global population will peak at 9.7 billion in 2064, according to researchers at the University of Washington, falling to 8.8 billion by the end of the century. The current world population is around 7.8 billion. The study runs counter to the U.N.’s prediction that the world’s population will reach its peak at nearly 11 billion around 2100.
