<P> 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 . 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 . The growth rate has declined to 1.18 % between 2010 and 2015 and is projected to decline to 0.13 % by the year 2100 . Total annual births were highest in the late 1980s at about 139 million , and are now expected to remain essentially constant at their 2011 level of 135 million , while deaths number 56 million per year and are expected to increase to 80 million per year by 2040 . The median age of 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 . </P>
