Hispanics or Latinos are those people who classified themselves in one of the specific Spanish, Hispanic, or Latino categories listed on the Census 2010 questionnaire -"Mexican," "Puerto Rican", or "Cuban"-as well as those who indicate that they are "another Hispanic, Latino, or Spanish origin." People who do not identify with one of the specific origins listed on the questionnaire but indicate that they are "another Hispanic, Latino, or Spanish origin" are those whose origins are from Spain, the Spanish-speaking countries of Central or South America, or the Dominican Republic. The terms "Hispanic," "Latino," and "Spanish" are used interchangeably.
Origin can be view as the heritage, nationality group, lineage, or country of birth of the person or the person's parents or ancestors before their arrival in the United States.
People who identify their origin as Spanish, Hispanic, or Latino may be of any race. Thus, the percent Hispanic should not be added to percentages for racial categories.
Non-Hispanic White alone persons. are individuals who responded "No, not Spanish/Hispanic/Latino" and who reported "White" as their only entry in the race question. Tallies that show race categories for Hispanics and non-Hispanics separately are also available.
