Objective: We calculate the cumulative and age-specific probabilities of coresidence with grandparents during childhood. We stratify our analyses by types of grandparent-grandchild living arrangements (grandfamilies and three-generation households) and by race and ethnicity.

Methods: We use two data sets -- the pooled 2010-2015 American Community Surveys (ACS) and the 1997 National Longitudinal Survey of Youth (NLSY-97) -- and produce estimates using life tables techniques.

Results: Results indicate that nearly 30% of US children ever coreside with grandparents. Both three-generation and grandfamily living arrangements are more prevalent among racial and ethnic minority groups, with three-generation coresidence particularly common among Asian children. Black children are nearly two times as likely to ever live in a grandfamily as compared to Hispanic and white children, respectively. Children are much more likely to experience grandparental coresidence during their first year of life than in any other year.

Cross-sectional estimates show that the share of children living with grandparents has risen over the last two decades, yet little is understood about a child's likelihood of ever living with a grandparent. In this paper, we calculate the cumulative and age-specific probabilities of coresidence with grandparents during childhood. We used the American Community Survey and the National Longitudinal Survey of Youth to create multi-decrement period life tables to study the prevalence and instability of grandparent coresidence. We examine differences between three-generation and grandfamily arrangements and explore patterns by race and ethnicity. Our results indicate that up to 31.5% of children ever co-reside with grandparents in either arrangement. We also find striking racial disparities in the probability of co-residing with grandparents that vary by type of grandparent household. Grandparental coresidence most commonly starts during the child's first year of life. Three-generation arrangements are highly unstable and short-lived.

The transformation of the American family under the second demographic transition has created more opportunities for parents to have children with multiple partners, but data limitations have hampered prevalence estimates of multiple-partner fertility from the perspective of children. This study uses nationally representative data from the 1979 and 1997 cohorts of the National Longitudinal Surveys of Youth to examine cohort change in children's exposure to multiple-partner fertility. We find that one in five children in the 1979 cohort had at least one half-sibling by their 18th birthday, and the prevalence grew to more than one in four children by the 1997 cohort. A strong educational gradient in exposure to half-siblings persists across both cohorts, but large racial/ethnic disparities have narrowed over time. Using demographic decomposition techniques, we find that change in the racial/ethnic and socioeconomic composition of the U.S. population cannot explain the growth in exposure to half-siblings. We conclude by discussing the shifting patterns of fertility and family formation associated with sibling complexity and considering the implications for child development and social stratification.

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.
