The world population's growth to eight billion people in 2022 – up from five billion in 1987, six billion in 1999, and seven billion in 2011 – reflects positive developments across fields such asglobal health andpoverty eradication. Significant reductions inglobal infant andmaternal mortality rates, especially in the 21st century, have led to dramatic increases inglobal life expectancy – and therefore the overall population.[5][6]
“This is a success story,"UNFPA Executive Director Dr.Natalia Kanem said onWorld Population Day (11 July) 2022. "Our world, despite its challenges, is one where higher shares of people are educated and live healthier lives than at any previous point in history."[7]

Amid global challenges such asclimate change and theCOVID-19 pandemic, several observers, includingDavid Attenborough, have expressed concerns about the future of the planet and its inhabitants as the population grows.[8][9][10][11]
Throughout history, fears regardingoverpopulation have often referenced the work of 18th-century economistThomas Malthus, who predicted humanity's growth would outpace its ability to sustain itself with resources.[10][12][13]
Others have pointed to declining fertility as a potential harbinger of demographic disaster. However, demography experts have challenged these theories, highlighting the diversity of countries’ population trends and the unlikelihood of any doomsday scenarios.[14][15][16]
“Population growth is currently concentrated in the world’s poorest countries, while some of the richest countries are beginning to see population decline," UNFPA Senior Adviser of Economics and Demography Michael Herrmann wrote on 11 July 2022.[14]
Overall, theUN Department of Economic and Social Affairs projects the global population will continue to grow, potentially peaking at an estimated 10.4 billion people during the 2080s – and staying there until 2100.[4]
The United Nations stated that they "can’t predict which exact baby will push us into the next billion".[17]Nonetheless, the Philippines' Commission on Population and Development selected Vinice Mabansag, a baby girl born inManila, as the symbolic eight billionth person on Earth.[18][19]
