In demographics, the world population is the total number of humans currently living, and was estimated to have reached 7.8 billion people as of March 2020.[2] It took over 200,000 years of human history for the world's population to reach 1 billion,[3] and only 200 years more to reach 7 billion.[4]
The world population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was near 370 million.[5] The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975—peaking to 2.1% between 1965 and 1970.[6] The growth rate declined to 1.2% between 2010 and 2015 and is projected to decline further in the course of the 21st century.[6] However, the global population is still increasing[7] and is projected to reach about 10 billion in 2050 and more than 11 billion in 2100.[8]
Total annual births were highest in the late 1980s at about 139 million,[9] and as of 2011 were expected to remain essentially constant at a level of 135 million,[10] while deaths numbered 56 million per year and were expected to increase to 80 million per year by 2040.[11] The median age of the world's population was estimated to be 30.4 years in 2018.[12] In mid-2019, the United Nations estimated that the world population had reached 7,713,468,000.[13]
If we do not STOP reproducing fast, the viruses will wipe out Homo Sapiens eventually.
Covid-19 is just the beginning.
