THE WORLD’S population may never grow as large as many had previously assumed. In a new paper, researchers at the Institute of Health Metrics and Evaluation at the University of Washington project that the global population will top out in 2064 and then fall steadily. Current estimates by the UN’s Population Division reckon it will continue to grow until at least 2100. As a result, the IHME estimates a total population of 8.9bn in 2100; the UN places the number at about 10.9bn.
