Most men expect to have children in their lifetime (FP-21-14), and the age men first become fathers has increased (FP-19-28). Less is known about when men stop having children. Using the 2015-2017 and 2017-2019 cycles of the National Survey of Family Growth (NSFG), this profile explores the median age at last birth among men at the end of their childbearing years (45 to 49 years old) by race/ethnicity, completed education, number of children, and age at first birth. Men start childbearing at older ages than women (FP-19-28; FP 21-05), and this profile shows that men also complete childbearing at older ages. The median age at last birth was 34 for fathers aged 45 to 49, and the median age at last birth for mothers aged 45-49 was 31 (FP 21-05).
