The fertility rate in the United States fell slightly to a historic low in 2025 as fewer teenagers and young women had babies, according to federal data released Thursday.

Roughly 3.6 million babies were born in the U.S. last year, a 1 percent decline from 2024, the study by the National Center for Health Statistics found. The overall fertility rate dropped to 53.1 births per 1,000 women — also a decrease of 1 percent and a historic low since the government began keeping such records, officials said.
