Conceptual and Methodological Issues in the Use of Race As a Variable: Policy Implications
Conceptual and Methodological Issues in the Use of Race as a Variable: Policy Implications DORIS Y. WILKINSON and GARY KING University of Kentucky; Westat, Inc. he classification of populations into discrete categories based on phenotypic or genotypic criteria is an accepted Tpractice in the physical and social sciences. In attempting to explain diverse physical characteristics and sociogeographical experiences among populations, the term “ race** has been employed for taxonomic purposes. In most scientific research, however, controversy and confusion have surrounded its use (Fortney 1977). For many scientists such as biologists, geneticists, and physical anthropologists, definitions have consisted primarily o f biological subject matter (e.g., gene pools, blood type, skin color). Social scientists, in contrast, have used the term to refer to behavioral practices (e .g ., cultural patterns, language), social factors (e.g., stratification, income status, discrimination) as well as phenotypic characteristics (e.g. hair texture, skin color, facial features). Yet, neither the biological nor sociological approach to racial classification is devoid o f serious theoretical and methodological shortcomings. Depending on the contextual application, the classification, definition, and recording o f data by race have important implications for health research and health policy. The social science translation has involved considerable complexity and varied theoretical and empirical emphases. Although the concept permeates social and behavioral science as well as epidemiologic research, its meaning is rarely specific or precise with respect to its components and the possible consequences of defining it in a particular way.
