How many babies are born in United States?

3.67 million babies born in United States in 2026. That is 2.77% of all births worldwide, and the 8th largest of any country. UN projection

2024–2100 uses the UN World Population Prospects 2024 medium scenario, based on assumptions about fertility, mortality and migration. These are projections, not observed births or guaranteed outcomes. Uncertainty increases further into the future; this site does not display prediction intervals.

What the numbers show

The highest annual births in United States among estimates through 2023 were in 1961, at about 4.38M. That is roughly 161 times the estimated ~27.2K births a year in 1 CE.

At 1.63 children per woman, fertility in United States is below the level of about 2.1 that would hold a population steady over the long run without migration.

How many babies are born in United States each year?

An estimated 3.67 million babies are born in United States in 2026, according to the UN World Population Prospects 2024 medium projection. That is about 10,100 a day and 2.77% of all births worldwide.

United States has an estimated 10.5 births per 1,000 people in 2026, and a total fertility rate of 1.63 children per woman.

Where these numbers come from

2026 figures are the UN World Population Prospects 2024 medium scenario. UN estimates cover 1950–2023; projections cover 2024–2100. Earlier years come from Gapminder’s reconstructions (1800–1949) and a model applied to HYDE population estimates (before 1800). The full chain is set out in the methodology, and every source is listed on the sources page.
