World population percentage by country
In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7.6 billion as of December 2017.[1] Estimates of the total number of humans who have ever lived range from 106 to 108 billion as of 2007.[2][3][4]Though the population is currently growing quite rapidly, future changes are influenced by difficult-to-predict factors such as economic development, cultural changes, migration, and natural disasters. Various mathematical models show that by 2100 the global population could be either rising or falling depending on how these factors affect birth and death rates.
World population has experienced continuous growth since the end of the Great Famine of 1315–17 and the Black Death in 1350, when it was near 370 million.[5] The highest population growth rates – global population increases above 1.8% per year – occurred between 1955 and 1975, peaking to 2.06% between 1965 and 1970.[6] The growth rate has declined to 1.18% between 2010 and 2015 and is projected to decline to 0.13% by the year 2100.[6] Total annual births were highest in the late 1980s at about 139 million,[7] and are now expected to remain essentially constant at their 2011 level of 135 million,[8] while deaths number 56 million per year and are expected to increase to 80 million per year by 2040.[9] The median ageof the world's population was estimated to be 30.1 years in 2016, with the male median age estimated at 29.4 years and female at 30.9 years.[10]
