Overview
- Provisional federal figures show 3,606,400 U.S. births in 2025 and a fertility rate of 53.1 per 1,000 women of childbearing age.
- Births increased for women in their 30s and 40s, yet larger declines among those under 30 point to later marriage and family formation.
- Teen birth rates fell 7% from 2024 to a new low, extending a long slide that has reduced teen births about 72% since 2007.
- Economists say fewer births and reduced immigration have slowed U.S. population growth to about 0.3% in 2025, which could weigh on medium‑term economic growth.
- Social Security’s trustees now expect the total fertility rate to reach about 1.9 children per woman around 2050, a slower recovery that worsens long‑range deficit projections.
