Race and ethnicity in the United States Census - Wikipedia, the free encyclopedia2010 Census
The 2010 US Census included changes designed to more clearly distinguish Hispanic ethnicity as not being a race. That included adding the sentence: "For this census, Hispanic origins are not races." Additionally, the Hispanic terms were modified from "Hispanic or Latino" to "Hispanic, Latino or Spanish origin".
Although used in the Census and the American Community Survey, "Some other race" is not an official race, and the Bureau considered eliminating it prior to the 2000 Census. As the 2010 census form did not contain the question titled "Ancestry" found in prior censuses, there were campaigns to get non-Hispanic West Indian Americans, Arab Americans and Iranian Americans to indicate their ethnic or national background through the race question, specifically the "Some other race" category.
