Abstract

After increases in the proportion of births occurring outside of marriage during the latter half of the 20th century into the early 2000s, the overall share has leveled off over the past decade, at roughly four in ten births (Martin et al., 2021). Much of the change in nonmarital childbearing was due to increases in births to cohabiting mothers (FP-15-03). Using data from several cycles of the National Survey of Family Growth (NSFG), this profile shows trends in the shares of births to single and cohabiting mothers under the age of 40 since the early 1980s, updating profiles FP-15-03 and FP-17-04.
