What was the Day of Eight Billion?
The UN identified 15 November 2022 as the milestone when the global population reached 8 billion. The milestone reflects long-term changes in survival, health and fertility; it is not a count of everyone alive on that date. The UN also noted that the time from 7 billion to 8 billion was about 12 years, while its 2022 projection placed 9 billion around 2037. See the UN’s original overview for the historical context and its definitions.
