■ Abstract This review examines research on the assimilation of immigrant groups.We review research on four primary benchmarks of assimilation: socioeconomic status, spatial concentration, language assimilation, and intermarriage. The existing literature shows that today's immigrants are largely assimilating into American society along each of these dimensions. This review also considers directions for future research on the assimilation of immigrant groups in new southern and midwestern gateways and how sociologists measure immigrant assimilation. We document the changing geography of immigrant settlement and review the emerging body of research in this area. We argue that examining immigrant assimilation in these new immigrant gateways is crucial for the development of theories about immigrant assimilation. We also argue that we are likely to see a protracted period of immigrant replenishment that may change the nature of assimilation. Studying this change requires sociologists to use both birth cohort and generation as temporal markers of assimilation.
The literature on assimilation and ethnic identity formation largely assumes that the durability of ethnic boundaries is a function of the assimilation measures that sociologists commonly employ. But this literature fails to account adequately for the role of immigration patterns in explaining the durability and nature of ethnic boundaries. Using 123 in-depth interviews with later-generation Mexican Americans, this article shows that Mexican immigrant replenishment shapes ethnic boundaries and ethnic identity formation. The sizable immigrant population sharpens intergroup boundaries through the indirect effects of nativism and by contributing to the continuing significance of race in the lives of later-generation Mexican Americans. The presence of a large immigrant population also creates intragroup boundaries that run through the Mexican-origin population and that are animated by expectations about ethnic authenticity. The article illustrates the importance of immigrant replenishment to processes of assimilation and ethnic identity formation.
The United States is embroiled in a debate about whether to protect or deport its estimated 11 million unauthorized immigrants, but the fact that these immigrants are also parents to more than 4 million U.S.-born children is often overlooked. We provide causal evidence of the impact of parents’ unauthorized immigration status on the health of their U.S. citizen children. The Deferred Action for Childhood Arrivals (DACA) program granted temporary protection from deportation to more than 780,000 unauthorized immigrants. We used Medicaid claims data from Oregon and exploited the quasi-random assignment of DACA eligibility among mothers with birthdates close to the DACA age qualification cutoff. Mothers’ DACA eligibility significantly decreased adjustment and anxiety disorder diagnoses among their children. Parents’ unauthorized status is thus a substantial barrier to normal child development and perpetuates health inequalities through the intergenerational transmission of disadvantage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
