Urban residents don't know their neighbors. They are basically "me" people. Unlike rural folks who have strong social interactions usually over long periods of time with several generations of families.
You forgot to mention that rural dwellers tend to be the most stuck up, cliquish people on the face of the earth. I lived in a tiny East Texas town for almost 10 years, and never did fit in. Moved back to my element, Dallas, and was amazed at how friendly the people are.
