Data is not available for counties in 2000. The Census Bureau defines 'Hispanic or Latino' as someone who classified his or herself as Cuban, Mexican, or Puerto Rican, or someone whose origins are from Spain, the Spanish-speaking countries of South or Central America, or the Dominican Republic. This classification is independent from the person's race.
