Which individuals belong to a racial group, and what determines membership? I argue that questions about membership are importantly different from questions regarding the ontology of racial categories and invite a distinctive line of inquiry. But there's a formidable challenge to providing determinate and consistent answers to membership questions: Many phenomena documented in sociology and psychology generate reasonable and systematic disagreement about membership that cannot be adjudicated by an influential variety of social constructionism. While the puzzle of racial identity remains, (...) we emerge with a new appreciation for how racial membership is a distinctive part of it. (shrink)

Race is one of the most common variables in the social sciences, used to draw correlations between racial groups and numerous other important variables such as education, healthcare outcomes, aptitude tests, wealth, employment and so forth. But where concern with race once reflected the view that races were biologically real, many, if not most, contemporary social scientists have abandoned the idea that racial categories demarcate substantial, intrinsic biological differences between people. This, in turn, raises an important question about the significance (...) of race in those social sciences: if there is no biological basis of race, why are racial categories useful to social scientists? More specifically, in virtue of what are racial categories a successful basis of informative, important social scientific generalizations? 2 We’ll call this social science’s race puzzle. (shrink)

In the United States, the racial and ethnic statistics published by the National Center for Health Statistics (NCHS) assume that each member of the U.S. population has a race and ethnicity and that if a member is black or white with respect to his risk of one disease, he is the same race with respect to his risk of another. Such an assumption is mistaken. Race and ethnicity are taken by the NCHS to be an intrinsic property of members of (...) a population, when they should be taken to depend on interest. The actual or underlying race or ethnicity of members of a population depends on the risk whose variation within the population we wish to describe or explain. (shrink)
