Using four waves of panel data from 6,954 American young adults in the National Education Longitudinal Study, we compare the long-term socioeconomic consequences of growing up in two types of divorced families. Our findings show that the negative socioeconomic consequences of growing up in unstable postdivorce families are at least twice as large as those of staying in a stabilized postdivorce family environment through late adolescence. The study also finds that variations in parental resources during late adolescence partially explain the divorce effects on most attainment indicators. Further, parental divorce appears to affect the socioeconomic attainment of male and female offspring alike. Overall, the study underlines the importance of including postdivorce family dynamics in studying the effect of parental divorce.
