One thing - possibly the only thing - I learned in my long ago course in Philosophy of Science, is that it's fruitless to argue about definitions. Nonetheless, it is useful to see how various people use a word. Here are the ways some people define the word "Hispanic:"
The term Hispanic (Spanish: hispano or hispánico, Galician: hispánico, Asturian: hispanu, Basque: hispaniar, Catalan: hispà, hispàno) broadly refers to the people, nations, and cultures that have a historical link to Spain. It commonly applies to countries once colonized by the Spanish Empire in the Americas (see Spanish colonization of the Americas) and Asia, particularly the countries of Latin America and the Philippines. It could be argued that the term should apply to all Spanish-speaking cultures or countries, as the historical roots of the word specifically pertain to the Iberian region. It is difficult to label a nation or culture with one term, such as Hispanic, as the ethnicities, customs, traditions, and art forms (music, literature, dress, architecture, cuisine, and others) vary greatly by country and region. The Spanish language and Spanish culture are the main traditions.
Hispanic originally referred to the people of ancient Roman Hispania, which roughly comprised the Iberian Peninsula, including the contemporary states of Spain, Portugal, Andorra, and the British Overseas Territory of Gibraltar.
Today, organizations in the United States use the term as a broad catchall to refer to persons with a historical and cultural relationship with Spain, regardless of race and ethnicity. The U.S. Census Bureau defines the ethnonym Hispanic or Latino to refer to "a person of Cuban, Mexican, Puerto Rican, South or Central American, or other Spanish culture or origin regardless of race" and states that Hispanics or Latinos can be of any race, any ancestry, any ethnicity. Generically, this limits the definition of Hispanic or Latino to people from the Caribbean, Central and South America, or other Hispanic (Spanish or Portuguese) culture or origin, regardless of race. Latino can refer to males or females, while Latina refers to only females.
The U.S. Office of Management and Budget (OMB) requires federal agencies to use a minimum of two ethnicities in collecting and reporting data: Hispanic or Latino and Not Hispanic or Latino. OMB defines "Hispanic or Latino" as a person of Cuban, Mexican, Puerto Rican, South or Central American, or other Spanish culture or origin regardless of race.
People who identify with the terms “Hispanic” or “Latino” are those who classify themselves in one of the specific Hispanic or Latino categories listed on the decennial census questionnaire and various Census Bureau survey questionnaires – “Mexican, Mexican Am., Chicano” or ”Puerto Rican” or “Cuban” – as well as those who indicate that they are “another Hispanic, Latino, or Spanish origin.”
The 2010 Census question on Hispanic origin included five separate response categories and one area where respondents could write in a specific Hispanic origin group. The first response category was intended for respondents who do not identify as Hispanic. The remaining response categories (“Mexican, Mexican Am., Chicano”; “Puerto Rican”; “Cuban”; and “another Hispanic, Latino, or Spanish origin”) and write-in answers can be combined to create the OMB category of Hispanic.
Definition of Hispanic
1 : of or relating to the people, speech, or culture of Spain or of Spain and Portugal
2 : of, relating to, or being a person of Latin American descent living in the U.S.; especially : one of Cuban, Mexican, or Puerto Rican origin
Anyone wishing to discuss in these pages who is or is not Hispanic should cite one of these or else provide their own definition from a credible standard source.
