When you are trying to learn a new language, one of the things you look for in a neighborhood is a place where nobody speaks your mother tongue, so that you are forced to learn the language to survive. We call this kind of neighborhood, "language-rich". Ours is pretty good, in this aspect, although many people will proudly use the few English phrases they know when they find out that we are Americans. However, many others speak Arabic only, as evidenced by one young man in his 20's who had no idea at all that his new sweatshirt read, "GRANDMA is my name and Spoiling is my Game!" That's language-rich!
