The 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and projected that it could drop even further to minus 0.1% by 2100. 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. Models of population growth take trends in human development and apply projections into the future. These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. Population projections are attempts to show how the human population statistics might change in the future. World population growth 1700–2100, 2022 projection
