We examine how recent immigration to the United States has affected African Americans. We first review the research on the growing diversity within the black population, driven largely by the presence of black immigrants from the Caribbean and Africa. As their children and grandchildren come of age, relations between immigrants and African Americans are complicated by the fact that a growing portion of the African American community has origins in both groups. We then review literature on both new destinations and established gateway cities to illustrate the patterns of cooperation, competition, and avoidance between immigrants of diverse races and African Americans in neighborhoods, the labor market, and politics. We explore the implications of the population’s increasing racial diversity owing to immigration for policies that aim to promote racial equality but that are framed in terms of diversity. We conclude with suggestions for new areas of research.

Current theories conceptualize return migration to New Orleans after Hurricane Katrina as an individual-level assessment of costs and benefits. Since relocation is cost prohibitive, return migration is thought to be unlikely for vulnerable populations. However, recent analyses of longitudinal survey data suggest that these individuals are likely to return to New Orleans over time despite achieving socioeconomic gains in the post-disaster location. I extend the “context of reception” approach from the sociology of immigration and draw on longitudinal data from the Resilience in the Survivors of Katrina Project to demonstrate how institutional, labor market, and social contexts influence the decision to return. Specifically, I show how subjective comparisons of the three contexts between origin and destination, perceived experiences of discrimination within each context, and changing contexts over time explain my sample’s divergent migration and mobility outcomes. I conclude with implications for future research on, and policy responses to, natural disasters.

As greater numbers of non-white immigrants enter the country, our racial justice policies are leaving behind longstanding racial minority populations.

The number of human cadavers available for medical research and training, as well as organ transplantation, is limited. Researchers disagree about how to increase the number of whole-body bequeathals, citing a shortage of donations from the one group perceived as most likely to donate from attitudinal survey data—educated white males over 65. This focus on survey data, however, suffers from two main limitations: First, it reveals little about individuals' actual registration or donation behavior. Second, past studies' reliance on average survey measures may have concealed variation within the donor population. To address these shortcomings, we employ cluster analysis on all whole-body donors' data from the Universities of California at Davis, Irvine, Los Angeles, and San Francisco. Two donor groups emerge from the analyses: One is made of slightly younger, educated, married individuals, an overwhelming portion of whom are U.S. born and have U.S.–born parents, while the second includes mostly older, separated women with some college education, a relatively higher share of whom are foreign born and have foreign-born parents. Our results demonstrate the presence of additional donor groups within and beyond the group of educated and elderly white males previously assumed to be most likely to donate. More broadly, our results suggest how the intersectional nature of donors' demographics, in particular, gender and migration status, shapes the configuration of the donor pool, signaling new ways to possibly increase donations.

Migrant networks—webs of social ties between migrants in destination and individuals in origin—are a key determinant of the magnitude and direction of migration flows, as well as migrants’ adaptation outcomes. The increasing emphasis on migrant networks represents a new approach to migration research, which until the late 1980s, had been dominated by economic or political explanations of migration.  This entry summarizes findings on migrant networks from relevant areas of research in anthropology, sociology, demography and economics; identifies the promising lines of inquiry recently undertaken; and points to key issues for future research, such as understanding how migrant networks impact migration behavior and migrants’ experiences. Such research into the specific mechanisms of social transmission will need to engage with the on-going discussions on networks effects and their identification in the social science literature at large, and will necessarily require the interdisciplinary collaboration of researchers.

Scholars have long noted how migration streams, once initiated, obtain a self-feeding character. Studies have attributed this phenomenon, called the cumulative causation of migration, to expanding social networks that connect migrants in destination to individuals in origin. Studies have often disagreed, however, on how social networks influence migration decisions. While many studies established a positive association between individuals’ ties to prior migrants and their migration propensities, only few acknowledged that multiple social mechanisms – as well as exposure to common environmental factors – might account for these interdependencies. To address this issue, we adopt a typology developed by DiMaggio and Garip (2012) and consider three mechanisms by which social ties may influence individuals’ migration choices. We study the prevalence of these mechanisms in the Mexico-U.S. migration context using a mixed methods approach. First, we analyze data from more than 90,000 individuals surveyed by the Mexican Migration Project (MMP), and establish the presence of network effects in migration. Specifically, we test how prior migrants in the family or community increase individuals’ migration propensities. We then analyze qualitative data from 120 in-depth interviews with migrants and their family members in Mexico to adjudicate among the different mechanisms that lead to interdependencies in individuals’ migration choices. We thus provide a deeper understanding of migration as a social process, which we contend is crucial for anticipating future flows and policy responses.

Scholars have long noted how migration streams, once initiated, obtain a self-feeding character. Studies have connected this phenomenon, called the cumulative causation of migration, to expanding social networks that link migrants in destination to individuals in origin. While extant research has established a positive association between individuals’ ties to prior migrants and their migration propensities, seldom have researchers interrogated how multiple social mechanisms—as well as exposure to common environmental factors—might account for these interdependencies. This article uses a mixed-methods strategy to identify the social mechanisms underlying the network effects in Mexico–U.S. migration. Three types of social mechanisms are identified, which all lead to network effects: (a) social facilitation, which is at work when network peers such as family or community members provide useful information or help that reduces the costs or increases the benefits of migration; (b) normative influence, which operates when network peers offer social rewards or impose sanctions to encourage or discourage migration; and (c) network externalities, which are at work when prior migrants generate a pool of common resources that increase the value or reduce the costs of migration for potential migrants. The authors first use large-sample survey data from the Mexican Migration Project to establish the presence of network effects and then rely on 138 in-depth interviews with migrants and their family members in Mexico to identify the social mechanisms underlying these network effects. The authors thus provide a deeper understanding of migration as a social process, which they argue is crucial for anticipating and responding to future flows.

Although a substantial literature examines the relationship between culture and health in myriad individual contexts, a lack of comparative data across settings has resulted in disparate and imprecise conceptualizations of the concept for scholars and practitioners alike. This article examines medical scholars and practitioners’ understandings of culture in relation to health interventions. Drawing on 142 interviews with officials from three different nongovernmental organizations working on health issues in multiple countries—Partners in Health, Oxfam America, and Sesame Workshop—we examine how these practitioners’ interpretations of culture converge or diverge with recent developments in the study of the concept, as well as how these understandings influence health interventions at three different stages—design, implementation, and evaluation—of a project. Based on these analyses, a tripartite definition of culture is built—as knowledge, practice, and change—and these distinct conceptualizations are linked to the success or failure of a project at each stage of an intervention. In so doing, the study provides a descriptive and analytical starting point for scholars interested in understanding the theoretical and empirical relevance of culture for health interventions, and sets forth concrete recommendations for practitioners working to achieve robust improvements in health outcomes.
