Family Formation in an Era of Family Change (ICPSR 34478)

Principal Investigator(s):


Using data from Wave I, II, and III of the National Longitudinal Study of Adolescent Health (ADD Health), the goal of this research was to provide a comprehensive analysis of the family formation behavior of young men and women in the contemporary United States. In particular, this study examined cohabitation, childbearing (non-marital and marital), and marriage up to the age of 25. This study differs from most prior research on early family formation in four key respects. First, the conceptual framework brings together theories, perspectives, and methods from the fields of family demography and human development. Using theories drawn from both fields, the study analyzed the influence of individual and social environmental characteristics in adolescence on cohabitation, marriage, and parenthood in emerging adulthood. Second, the research focused both on specific family formation transitions and on the trajectories generated by the timing and sequencing of family formation behaviors, education, and employment. Third, in addition to analyzing the social demographic and developmental precursors of family formation behaviors, the study also explored the implications of family formation patterns for psychosocial well-being in emerging adulthood, including psychological and behavioral adjustment, psychosocial maturity, and intimate relationship quality. Fourth, this project paid rigorous attention to the roles of race/ethnicity and gender in the processes of early family formation and in the implications for well-being of divergent family formation patterns.
