Models of population growth take trends in human development and apply projections into the future. These models use trend-based-assumptions about how populations will respond to economic, social and technological forces to understand how they will affect fertility and mortality, and thus population growth. The 2022 projections from the United Nations Population Division (UN) (chart #1) show that annual world population growth peaked at 2.2% per year in 1964, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% by 2100.
