The population growth rate estimates (according to the United Nations Population Prospects 2019) between 2015 and 2020 [1] This article includes a table of countries and subnational areas by annual population growth rate.
Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. [1] According to the most recent United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide.
(2011) World population growth rates between 1950 and 2050. The world population growth rate peaked in 1963 at 2.2% per year and subsequently declined. [11] In 2017, the estimated annual growth rate was 1.1%. [30] The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.86%, 0.78%, and 1.08% respectively. [31]
The UN Population Division report of 2022 projects world population to continue growing after 2050, although at a steadily decreasing rate, to peak at 10.4 billion in 2086, and then to start a slow decline to about 10.3 billion in 2100 with a growth rate at that time of -0.1%.
The current world population growth is approximately 1.09%. [7] People under 15 years of age made up over a quarter of the world population (25.18%), and people age 65 and over made up nearly ten percent (9.69%) in 2021. [7] The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.
Population of the present-day top seven most-populous countries, 1800 to 2100. Future projections are based on the 2024 UN's medium-fertility scenario. Chart created by Our World In Data in 2024. The following is a list of countries by past and projected future population. This assumes that countries stay constant in the unforeseeable future ...
In 1975, Sebastian von Hoerner proposed a formula for population growth which represented hyperbolic growth with an infinite population in 2025. [141] The hyperbolic growth of the world population observed until the 1970s was later correlated to a non-linear second-order positive feedback between demographic growth and technological development.
