According to a survey released by the Pew Hispanic Center, only 24% of "Hispanic" adults said they most often identified themselves as Hispanic or Latino. About half said they identified themselves most frequently by their family's national origin, e.g. Mexican, Cuban or Salvadoran. An additional 21% said they called themselves American most often, a figure that climbed to 40% among those born in the U.S.[1]
Many people are beginning to find it offensive to be called Hispanic or Latino and prefer to be called simply by their true ethnic group such as Mexican, Colombian, Bolivian etc.
