(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]
If this trend continues, the rate of growth may diminish to zero by 2100, concurrent with a world population plateau of 10.9 billion. [4] [66] However, this is only one of many estimates published by the UN; in 2009, UN population projections for 2050 ranged between around 8 billion and 10.5 billion. [108]
