The Census Bureau uses the U.S. Office of Management and Budget's (OMB) standards for race, and uses their five categories: white, black or African-American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. They also use the sixth category of "some other race." The 2010 Census was the second time people were able to identify in more than one of the five main categories.
