Abstract

Changes in the stability of cohabiting and marital unions, combined with changes in nonmarital childbearing, means many of today’s unions result in the formation of stepfamilies – unions in which one or both partners have a child from a previous relationship, regardless of whether those children live in the household. This profile combines new NCFMR analyses of the 2015-2019 National Survey of Family Growth (NSFG) data with published analyses of 1988 NSFG data (Guzzo, 2017), focusing on women under age 45 who lived with a partner (married or cohabiting) at the time of the survey. It examines shifts in the share of unions that are stepfamilies, shifts in the share of stepfamilies that are marriages versus cohabitations, and shifts in which partner has children from a past relationship (i.e., whether the female partner, male partner, or both have a child from a prior union). The 2015-2019 NSFG data represents the year 2017 when weighted.
