I wuld say so. If you look at the map below, you'll see that there are a few areas like parts of Toms River and Somerville that are starting to see a large number of Hispanics, and then you have areas like Freehold, North Plainfeld, Bound Brook, and some of the areas bordering Paterson (I guess you could call them Paterson's "suburbs" like Prospect Park) that have always had a Hispanic population, but are starting to become predominantly Hispanic. And then you have a few areas like Dover which have been predominantly Hispanic for a while now.
