The U.S. Census data on race and ethnicity is constantly changing because of problems of definition and categorization. For instance, in the past, the Census allowed respondents to select only one race, but now they can select multiple races. Additionally, the categories used to define race have changed over time, making it difficult to compare data from different decades.
