Childhood Family Instability and Young-Adult Union Experiences: Black-White Differences in Outcomes and Effects.

Today's young adults have diverse union experiences; some enter enduring marital or cohabiting unions at young ages, but many delay or dissolve their unions or remain single. Childhood family instability-defined as parents' transitions into or out of romantic coresidential unions-offers one explanation for why some people are more likely than others to enter and exit unions. We evaluate whether this family instability hypothesis-a union-specific version of the general hypothesis that instability affects people across multiple life domains-can explain Black and White young adults' union formation and dissolution. Using data from the Panel Study of Income Dynamics' Transition into Adulthood Supplement (birth cohorts 1989-1999), we find that the marginal effects of childhood family instability on cohabitation and marriage are weaker for Black than for White youth. Further, Black-White differences in childhood family instability's prevalence are small. Consequently, novel decompositions that account for racial differences in instability's prevalence and marginal effects reveal that childhood family instability contributes little to Black-White inequality in young adults' union outcomes. Our results challenge the generalizability of the family instability hypothesis across racialized groups in the union domain. Explanations for Black-White differences in young-adult marriage and cohabitation reside beyond childhood family dynamics.
