Trends and differentials in the age at first birth are well-documented (FP-20-06). Given shifts and variation in completed family size (FP-20-04), it is also important to look at the age of last birth – that is, when do women stop having children – which has received very little attention. This profile investigates the median age at last birth among women at the end of their childbearing years, at 45-49 years old. Using the 2015-2019 cycles of the National Survey of Growth, this profile investigates the median age at last birth for mothers aged 45-49 by race/ethnicity, completed education, parity, and age at first birth.
