In 2015, the United Nations predicted that the global population could surpass 11 billion by the end of the century.
Last year, the UN revised these estimates, but the numbers it came up with were still well above 10 billion. These regular projections from the UN have been the status quo—until now.
Plenty of signs have pointed to there being a population plateau, but recent research from the Institute for Health Metrics and Evaluation (IHME), published in The Lancet, suggests that the number of people on this planet may actually start to shrink well before the year 2100.
This visualization takes a closer look at these complex projections.
