UN: World’s population hits 8 billion on Tuesday
Brad Dress, Tue, November 15, 2022
The United Nations said the world population hit 8 billion people on Tuesday, although overall growth rates in the total population are slowing.
The 8 billionth person was born somewhere in the world on Tuesday, according to U.N. projections.
The population milestone was reached owing to a gradual increase in the average human lifespan, accomplished through improvements in medicine and public health.
It took just 12 years for the world population to grow from 7 billion to 8 billion people, but the U.N. projects it will take 15 years to reach 9 billion people, a milestone expected to be reached by 2037. …
It took all of human history to reach 1 billion people in the early 19th century, and about 123 years to reach 2 billion and 33 years to reach 3 billion people in 1960.
But the global population is expected to decline toward the end of the century.
The U.N. estimated in a report this year the global population will peak at 10.4 billion around 2080, mostly because of declining birth rates.
