![]() The total number of deaths is currently 57 million/year and is projected to grow steadily to 121 million/year by 2100. The total number of births globally is currently (2015–2020) 140 million/year, which is projected to peak during the period 2040–2045 at 141 million/year and then decline slowly to 126 million/year by 2100. ![]() Other demographers predict that the human population will begin to decline in the second half of the 21st century. The UN Department of Economics and Social Affairs projects between 9 and 10 billion people by 2050 and gives an 80% confidence interval of 10–12 billion by the end of the 21st century, with a growth rate by then of zero. The global population is still increasing, but there is significant uncertainty about its long-term trajectory due to changing fertility and mortality rates. The growth rate declined to 1.1% between 20 and is projected to decline further in the 21st century. The highest global population growth rates, with increases of over 1.8% per year, occurred between 19, peaking at 2.1% between 19. The human population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was nearly 370,000,000. It took around 300,000 years of human prehistory and history for the human population to reach one billion and only 222 years more to reach 8 billion. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. In world demographics, the world population is the total number of humans currently living.
