The U.S. Census Bureau projects the U.S. population to reach 341,145,670 on New Year’s Day, an annual increase of 2,640,171 or 0.78% and with the addition of one international migrant entering the country every 23 seconds.
The combination of births, deaths and net international migration increases the U.S. population by one person every 21.2 seconds, according to the U.S. Census Bureau report released today. Population of a country is often associated as both a contributor for the growth of an economy and a burden especially if not productive enough.
“By comparison, just before the nation’s independence nearly 250 years ago, the 13 colonies had about 2.5 million residents. The projected world population on January 1, 2025, is 8,092,034,511, up 71,178,087 (0.89%) from New Year’s Day 2024. During January 2025, 4.2 births and 2.0 deaths are expected worldwide every second,” it said.
Since 1950, population growth rates in developing countries have averaged around 2 per cent per year, enough to double the size of a country’s population in 35 years. The calculation is not merely hypothetical; the population of the developing world (Africa, Latin America and Asia, except Japan) has in fact doubled between 1950, when it numbered 1.7 billion, and 1984, when it reached 3.6 billion.
World Population Projections
The Census Bureau’s International Database (IDB) created in the 1960s now produces population projections for 227 countries and equivalent areas, plus 16,919 subnational areas.
Population size (by single year of age and sex) and components of change (fertility, mortality and migration) are available for each calendar year through 2100. The IDB was last updated in November and is set to be updated again next November. The United States is expected to remain the world’s third most populous country in 2025.
As of July 2024, the top 10 most populous countries were India (1,409,128,296); China (1,407,929,929); the United States (336,673,595); Indonesia (281,562,465); Pakistan (252,363,571); Nigeria (236,747,130); Brazil (220,051,512); Bangladesh (168,697,184); Russia (140,820,810); and Mexico (130,739,927).
Population estimates from U.S. and World Population Clocks
The Census Bureau’s Population Clock displays simulated real-time growth of the U.S. and world populations The U.S. Population Clock shows the population by age (0 to 100+) and sex, as well as the highest-density states, counties and cities.
In January 2025, the United States is expected to experience one birth every 9.0 seconds and one death every 9.4 seconds. Net international migration is expected to add one person to the U.S. population every 23.2 seconds.
