Over the past decade, the Hispanic population has grown in areas with little to no history of recent immigration. Prior research comparing Hispanics in new and established destinations has chiefly focused on differences in socioeconomic indicators of assimilation. Our article departs from this work by shifting the focus to sociocultural outcomes. Specifically, we use data from Los Angeles and North Carolina to examine differences in the strength of family obligation (N = 552). We find that demographic characteristics explain all of the geographic difference in family obligation between these locations. However, we also find that co-ethnic concentration is positively correlated with adolescents’ endorsement of future family support, once ethnic identity is included in the analysis.
