Hispanic is considered an ethnicity, not a race, in the United States; therefore, Hispanics may also consider themselves Caucasian. Others may consider themselves ethnically Hispanic and racially black. The U.S. Census form lists “Hispanic, Latino or Spanish origin" as a separate question from the question asking about a person's race.
Hispanics, or Latinos, are people who have genealogical origins in Spain or Latin America. They are a group with a shared linguistic and cultural history, rather than a race. Instead, Hispanics are racially diverse and cannot be categorized into one race. As of 2015, Hispanic Americans are the second fastest-growing group in the U.S.
