How unusual is it that I have only lived in two places, twelve miles from each other?

I typically look at someone’s fluther before I respond to a question, and as I looked over the places I’ve lived section, it hit me. I live one county over from where I was born. I’ve traveled some, but how unusual is it to live in such a small area? It is New York State, so that may change, as bad as this state is governed. How many others have only lived in a few places?
