US births fell last year, marking an end to the late pandemic rebound, experts say
NEW YORK — 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.
Birth rates have long been falling for teenagers and younger women, but rising for women in their 30s and 40s — a reflection of women pursuing education and careers before trying to start families, experts say. But last year, birth rates fell for all women younger than 40, and were flat for women in their 40s.
Mark called that development surprising and said “there’s some evidence that not just postponement is going on.”
Rates fell across almost all racial and ethnic groups.
The numbers released Thursday are based on more than 99.9% of the birth certificates filed in 2023, but they are provisional and the final birth count can change as they are finalized. For example, the provisional 2022 birth count appeared to show a dip, but ended up being higher than 2021’s tally when the analysis was completed.
There could be an adjustment to the 2023 data, but it won’t be enough to erase the “sizeable” decline seen in the provisional numbers, said the CDC’s Brady Hamilton, the new report’s first author.
Experts have wondered how births might be affected by the June 2022 U.S. Supreme Court decision that allowed states to ban or restrict abortion. Experts estimate that nearly half of pregnancies are unintended, so limits to abortion access could affect the number of births.
The new report indicates that the decision didn’t lead to a national increase in births, but the researchers didn’t analyze birth trends in individual states or dissect data among all demographic groups.
The new data does raise the possibility of an impact on teens. The U.S. teen birth rate has been falling decades, but the decline has been less dramatic in recent years, and the drop seems to have stopped for teen girls ages 15 to 17.
