A white paper released by Experian Marketing Services reports that three-quarters of Hispanic adults prefer to speak at least some Spanish
Among all Hispanics, there is about an even split between the percentage who prefer to speak mostly or only English versus only or mostly Spanish.
However, when we look at Hispanics by generation, those born outside the U.S. (first generation) favor speaking Spanish by a wide margin. Among second generation Hispanics, those born in the U.S. to at least one foreign-born parent, a clear majority prefer to speak either all or mostly in English.
Even though 55% of third generation Hispanics, those born in the U.S. to American-born parents, say they prefer to speak only in English, the remainder says that they still prefer to speak Spanish at least some of the time.
