Birth rates continue to be highest among women ages 25 to 29 and women ages 30 to 34 at over 90 births per 1,000 women. Women ages 40 to 44 saw the largest increase in birth rate at 12.5 births per 1,000 women, a 4% increase from 2021.

Among teenagers ages 15 to 19, the estimated birth rate declined to a record low of 13.5 births per 1,000 women. Teen birth rates have declined by an annual average of 8% every year since 2009. However, the teen birth rate only declined by 3% from 2021 to 2022.

"It definitely differs from the pattern that we have seen before, and certainly one of the things that we'll look at once we get the final data, looking at it in terms of the rates by state, and looking at it in detail in terms of race and Hispanic origin," Hamilton said.

In 2019 and 2020, almost all racial and ethnic groups saw a decrease in fertility rates. Since then, only a few groups have seen their fertility rates increase again.

In 2022, Hispanic women saw a 4% increase in fertility rates, reaching 66.1 births per 1,000 women. In addition, Asian women had a 3% increase, and Native Hawaiian and Pacific Islander women had a 6% increase. In comparison, Black and white women had slight decreases in their fertility rates from 2021.

According to CBS News, the current data is only provisional, and final estimates will be published later this summer. However, it is unlikely there will be significant changes in the finalized figures. Instead, the final report will include further details and analyses, including how trends vary by age and by state.

"There's never a very large difference in terms of the final data versus the provisional data," Hamilton said. "And in our report, we noted that we've collected roughly 99.99% of the records that we expect to see in terms of the final data, so it tracks well, and the general patterns you see should hold up."
