Issues of Classification in Environmental Equity: How We Manage is How We Measure

This Article addresses how concepts of race and ethnicity have been operationalized as a basis for defining and locating subpopulations (either explicitly or implicitly) for the purpose of analyzing environmental equity issues, and recommends some future directions. Part II focuses on how subpopulations are currently defined and on some problems encountered to date. The implications of these inconsistencies on the accuracy of health and environmental risk measures for a given subpopulation are addressed. Part III focuses on how spatial areas have been defined to aggregate these subpopulations within confined geographic boundaries
