Following up on research on the post-1965 “new second generation,” we turn our attention to the “new third generation.” Using Census and Current Population Survey data, we compare family and household characteristics of post-1965, second-generation Latino and Asian children in 1980 to third-generation children in 2010. We also examine the relationship between household characteristics and three outcomes: intermarriage, ethnic/racial identification for children with intermarried parents, and multigenerational households.
