Estimated 7.58 Billion People in the World Today
The United Nations declared July 11 as World Population Day in 1989, two years after world population crossed the 5 billion mark.
According to the U.S. Census Bureau, from 10,000 BC through the early 1800s, the world population stayed below 1 billion globally. By the 20th Century, population totals soared, more than doubling between 1920 and 1980 from fewer than 2 billion people to almost 4.5 billion in 60 years.
Population records from 1988 - 2050 AD: The U.S. Census Bureau’s International Data Base shows that world population increased by more than 50% in the 32 years since the Day of Five Billion in 1987.
While this growth has been rapid, annual global population growth rate actually peaked in the early 1960s at 2.2%. It has since gradually begun to decline.
In fact, the Census Bureau’s International Data Base projects 2020-2021 to be the first year since 1950 where the annual population growth rate will drop below 1%. That number is expected to continue to drop.
