US births rose slightly last year, but experts don't see it as evidence of reversing a long-term decline, per the AP. Details, including the continued rise in the age of new mothers to 27 1/2:

  • A little over 3.6 million births were reported for 2024, according to Centers for Disease Control and Prevention preliminary data. That's 22,250 more than the final tally of 2023 US births, which was released Tuesday.
  • The 2024 total is likely to grow at least a little when the numbers are finalized, but another set of preliminary data shows overall birth rates rose only for one group of people: Hispanic women.

  • The overall rise—less than 1%—may just be a small fluctuation in the middle of a broader trend, said Hans-Peter Kohler of the University of Pennsylvania. "I'd be hesitant to read much into the 2023-24 increase, and certainly not as an indication of a reversal of the trend towards lower or declining US fertility," Kohler said.
  • US births and birth rates have been falling for years. They dropped most years after the 2008-09 recession, aside from a 2014 uptick. They also dropped in 2020, the first year of the COVID-19 pandemic, then rose for two straight years after that, an increase experts partly attributed to pregnancies put off amid the pandemic.
  • A 2% drop in 2023 put US births at fewer than 3.6 million, the lowest one-year tally since 1979. Vermont had the lowest birth rate that year, and Utah had the highest, according to Tuesday's 86-page report on 2023 birth data.
  • The report, based on a review of all the birth certificates filed in 2023, shows the average age of mothers at first birth has continued to rise, hitting 27 1/2 years. It was 21 1/2 in the early 1970s, before beginning a steady climb. Birth rates fell for women in almost all age groups in 2023, include women in their early 40s.
  • Preliminary birth rate data for 2024 shows a continued decrease among teenagers and women in their early 20s. But it also showed increases for women in their late 20s, due entirely to a rise in births to Hispanic women. Increases also were seen for women in their 30s, due to rises among Hispanic and white women, and those in their 40s, due to rises among white women.
