World Population Day: July 11, 2022

Observed on July 11 every year since 1989.

The populations displayed on the clock at Population Clock: World (census.gov) are not intended to imply that the population of the world is known to the last person. Rather, the clock is the Census Bureau's estimate of the world population size and an indication of how fast it is growing. According to current estimates, the world population reached 7 billion in 2011 and the new projections indicate that the 8 billion markers will be reached in 2023.

In the U.S. alone the Census Bureau estimates the population size to be around 332 million and counting, with one birth every 8 seconds, one death every 11 seconds, and one international migrant every 130 seconds.
