Whether preventing future regrets, waiting to find the right partner or focusing on careers and financial stability first, more women over 40 are becoming first-time moms. While birth rates are down in the United States and across the globe, fertility rates have risen among American women 40 and older. From 2023 to 2024, birth rates declined for women aged 15-34, were unchanged for women aged 35-39 and rose 2% for women aged 40-44, according to the most recent data released in July of 2025.
Because some women are waiting longer to start having kids, America’s declining fertility rate “may not be as big as it seems,” said Emily Oster, an economics professor at Brown University and CEO of ParentData, a parenting research forum. There’s a chance the United States sees more births in the next several years, she said, though women who become first-time moms in their 40s still face barriers.
