Forecast World Population
The current (December 2022) world population is in excess of 8 billion, with a UN forecast median of approximately 10.4 billion by the year 2100. The forecast 95% probabilistic range for 2100 is a high of approximately 12.4 billion and a low of approximately 8.9 billion persons (United Nations Department of Economic and Social Affairs - Population Division, 2022). An alternative year 2100 population forecast is provided by Vollset et al. (2020) which includes a predicted value of 8.79 billion with a 95% Uncertainty Interval high of 11.8 billion and low of 6.83 billion. The lower forecast of Vollset et al. (2020) utilises a decreasing reproductive rate as a function of the number of years of education. This beneficial education-years relationship can serve as a reference tool in the design of birth reduction programs.
