Census data reveal that 68% of American adults are non-Hispanic whites. Hispanics (14%) are the largest ethnic minority group, followed by African-Americans (12%) and Asians (5%). Among Affluents (those with a household income of at least $100,000), 77% are non-Hispanic whites, and the three major ethnic minorities are roughly equal in size, each comprising 7-9% of the Affluent population. In relative terms, Hispanics and African-Americans are underrepresented (less prevalent among Affluents than among the general population), while Asians are slightly overrepresented.
