Young Adults' Roles as Partners and Parents in a Context of Family Complexity.

This article uses data from the 1979 and 1997 cohorts of the National Longitudinal Survey of Youth to estimate the proportions of young men and women who will take on a variety of partner and parent roles by age 30, as well as to describe how these estimates have changed across cohorts. It then draws from identity theory and related theoretical work to consider how the multiple family roles which young adults are likely to occupy-both over their life course and at a single point in time-may influence inter- and intra-family (unit) relationships in light of current trends in family complexity. This discussion highlights four key implications of identity theory as it relates to family complexity, and proposes several hypotheses for future empirical research to explore, such as the greater likelihood of role conflict in families with greater complexity and limited resources. Implications for public policy are also discussed.
