World Population Day: July 11, 2025
World Population Day has been observed on July 11 every year since 1990.
The World Population Clock provides an estimate of the global population at a given moment as well as an indication of how fast it is growing.
The U.S. Census Bureau estimates the number of people in the world population by combining past population growth statistics with data for individual countries and areas from the International Database (IDB).
The world population reached 8 billion in 2023. It is projected to reach 8.1 billion this year, 9 billion in 2038, 10 billion in 2057 and peak at 10.9 billion in 2098 before declining, according to IDB projections.
The Census Bureau developed these estimates by analyzing available population, fertility, mortality and migration data. For most countries, adjustments to the data are necessary to correct for errors. Some available data for estimates may be several years old, so the population data used for our World Population Clock are projections from those earlier estimates. As new data become available, estimates and projections may change.
Observed on July 11 every year since 1990.
