Multiple-partner Fertility and the Growth in Sibling Complexity Presented: Montreal, QC, American Sociological Association Annual Meeting, August 2017 Cohort(s): NLSY79, NLSY97 Publisher: American Sociological Association Keyword(s): Fertility, Multiple Partners; Siblings Permission to reprint the abstract has not been received from the publisher. The transformation of the American family, fueled by cohabitation, divorce, and nonmarital childbearing, has created opportunities for parents to have children with more than one partner. Family scholars have documented the extent of maternal and paternal multiple-partner fertility in the US population, but we know less about these processes from the perspective of children, for whom parental multiple-partner fertility manifests as the presence of half-siblings. This paper uses the 1979 and 1997 Cohorts of the National Longitudinal Surveys of Youth to examine cohort change in children’s exposure to sibling complexity. We find that the probability of having a half-sibling increased by 30 percent between the two cohorts, with over one in four children now having at least one half-sibling by their 18th birthday. A strong educational gradient in sibling complexity persists across both cohorts, but large racial-ethnic disparities in sibling complexity have narrowed over time. Using demographic decomposition techniques, we find that the shifting racial-ethnic and socioeconomic composition of the U.S. population cannot explain the growth in sibling complexity. We conclude by discussing the shifting relationship contexts that have fueled sibling complexity and considering the implications for child development and social stratification.
