Why do the race and ethnicity totals sum to more than 100 percent for some studies?
The Pathways Clearinghouse strives to present a complete set of race and ethnicity data for each study, in accordance with the federal standards for classifying data on race and ethnicity. In practice, for most studies this means that an individual can fall only into single race or ethnicity category. For example, a person would identify as either Hispanic or Black, but not both.
