Images and interpretations of the past, present, and future of the American racial and ethnic landscape are contradictory. Many accounts focus on the increasing diversity that results from immigration and differential natural increase as well as the proliferation of racial and ethnic categories in census data. Less attention has been paid to the formation and erosion of racial and ethnic identities produced by intermarriage and ethnic blending. The framers and custodians of census racial classifications assume a “geographic origins” definition of race and ethnicity, but the de facto measures in censuses and social surveys rely on folk categories that vary over time and are influenced by administrative practices and sociopolitical movements. We illustrate these issues through an in‐depth examination of the racial and ethnic reporting by whites, blacks, Asians, and Hispanics in the 2000 census. The emerging pattern, labeled here as the “Americanization” of racial and ethnic identities, and most evident for whites and blacks, is of simplified racial identities with little acknowledgment of complex ancestries. National origin is the predominant mode of reporting racial and ethnic identities among Asians and Hispanics, especially first‐generation immigrants. The future of racial and ethnic identities is unknowable, but continued high levels of immigration, intermarriage, and social mobility are likely to blur contemporary divisions and boundaries.

Five percent of typical oral contraceptive users experience an unintended pregnancy every year. Inconsistent use of oral contraception may be a leading contributor to the high rate of unintended pregnancy among oral contraceptive users. Previous medical research also suggests that anxiety may play a role in medication compliance, yet no known studies have examined the relationship between anxiety and oral contraceptive use. To test this relationship, the authors analyze data from the National Survey of Family Growth Cycle V (NSFG-V), restricting their sample to sexually active women currently taking oral contraceptives. They find that women who report multiple episodes of anxiety lasting at least 6 months have a greater probability of inconsistent use. The authors suggest goals for future research and discuss the role of health care professionals in addressing oral contraception compliance in light of their findings.

This article investigates the role of policing in both the genesis and development of racial rioting. In particular, the authors focus on several riots that occurred in two cities, Boston and San Francisco, which experienced different overall levels of rioting during the peak period of racial violence in thelate1960s. The amount and type of rioting that occurred in each city is consistent with the paradoxical yet frequent pattern in which direct repression, particularly when characterized by excessive or selective use of force, fails to subdue rioting and often escalates conflict. Despite this consistency, however, there are substantial differences between the two cities concerning the amount and severity of rioting that occurred. These differences are connected to variation in three primary characteristics of the civil authorities in the two cities: (a) police preparedness and training, (b) racial polarization in attitudes toward the police, and (c) underlying police-community relations. Implications are then discussed for further research on racial rioting and for policing practices.

This paper presents a residual methods approach to identifying social mobility across race/ethnic categories. In traditional demographic accounting models, population growth is limited to changes in natural increase and migration. Other sources of growth are absorbed by the model residual and can only be estimated indirectly. While these residual estimates have been used to illuminate a number of elusive demographic processes, there has been little effort to incorporate shifts in racial identification into formal accounts of population change. In light of growing evidence that a number of Americans view race/ethnic identities as a personal choice, and not a fixed characteristic, mobility across racial categories may play important roles in the growth of race/ethnic sub-populations and changes to the composition of the U.S. To examine this potential, we derive a reduced-form population balancing equation that treats fertility and international migration as given and estimates survival from period life table data. After subtracting out national increase and migration and adjusting the balance of observed growth for changes in racial measurement and census coverage, we argue that the remaining error of closure provides a reasonable estimate of net interracial mobility among the native born. Using recent Census and ACS microdata, we illustrate the impact that identity shifts may have had on the growth of race/ethnic sub-populations in the past quarter century. Findings suggest a small drift from the non-Hispanic white population into race/ethnic minority groups, though the pattern varies by age and between time periods.
