During the 1970s, the United States Government defined the term "Hispanic" to identify Latin American individuals, and their descendants, living in the U.S., regardless of race.
The ethnic label Hispanic was the result of efforts by a New Mexican U.S. Senator, Joseph Montoya, who wanted a label that could be used to quantify the Spanish-speaking population for the US Census. The label Hispanic was chosen in part because in New Mexico, people of Spanish descent such as Montoya referred to themselves as hispanos which was anglicized as "Hispanic".
The U.S. Office of Management and Budget currently defines "Hispanic or Latino" as "a person of Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race".
