Change in population = 100,000 – 80,000 +1,000 – 200 = 20,800. Population growth rate = (20,800 ÷ 1,000,000) x 100% = 2.1%. Zero population growth for a country occurs when the sum of these four numbers – births minus deaths plus immigration minus emigration - is zero. To illustrate, suppose a country begins the year with one million ...

(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 growth rate is 0.1% as estimated for 2021. [81] The birth rate is 11.0 births/1,000 population, as of 2020. [42] This was the lowest birth rate since records began. There were 3,613,647 births in 2020, this was the lowest number of births since 1980. [42] 11.0 births/1,000 population per year (final data for 2020).
The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975, peaking at 2.1% between 1965 and 1970. [3] The growth rate declined to 1.1% between 2015 and 2020 and is projected to decline further in the 21st century. [4]
