A little under 3.6 million babies were born in 2023, according to provisional statistics released by the Centers for Disease Control and Prevention. That’s about 76,000 fewer than the year before and the lowest one-year tally since 1979.

U.S. births fell last year, resuming a long national slide.

A little under 3.6 million babies were born in 2023, according to provisional statistics released Thursday by the Centers for Disease Control and Prevention. That’s about 76,000 fewer than the year before and the lowest one-year tally since 1979.

U.S. births were slipping for more than a decade before COVID-19 hit, then dropped 4% from 2019 to 2020. They ticked up for two straight years after that, an increase experts attributed, in part, to pregnancies that couples had put off amid the pandemic’s early days.

But “the 2023 numbers seem to indicate that bump is over and we’re back to the trends we were in before,” said Nicholas Mark, a University of Wisconsin researcher who studies how social policy and other factors influence health and fertility.
