Hispanic or Latino?
They are multilingual but Hispanics may not identify with being Latino, not the same way in reverse.
Latinos I know have no problem being identified as Hispanics, but that is not always the case in reverse. Latinos refers to geography and Hispanics to the language, try explaining that to a Hispanic and insist they are Latinos.
US now has more Spanish speakers than Spain and the second most in the world, according to a recent study.
