here is the definition for hispanic
Hispanic, as used in the United States, is one of several terms used to categorize persons whose ancestry hails either from Spain, the Spanish-speaking countries of Latin America, or the original settlers of the traditionally Spanish-held Southwestern United States. The term is used as a broad form of classification in the U.S. census, local and federal employment, and numerous business market researches.
In Spain and Spanish-speaking Latin America, Hispano ("Hispanic") is ascribed as indicating a derivation from Spain, her people and culture. It follows the same style of use as Anglo indicates a derivation of England and the English. Thus, the Spanish-American War in Spanish is known as "Guerra Hispano-Estadounidense", the "Spanish-German Treaty" as "Tratado Hispano-Alemán", "Spanish America" as Hispanoamérica, etc.
