Behind the numbersOpen
CDC/NCHS reports mean age at first birth from the National Vital Statistics System. CDC FastStats lists 24.9 in 2000 and 27.5 in 2023. A 2025 National Vital Statistics Report found the mean age of mothers at first birth increased from 26.6 in 2016 to 27.5 in 2023. BGSU’s National Center for Family & Marriage Research summarizes the 2010-to-2023 increase from 25.4 to 27.5. This is not proof that people want fewer children; it shows first births are happening later, which changes fertility windows, career timing, grandparents’ ages, and family planning risk.
