Census Bureau data show that about 70% of people who live in Alabama were born there. "People tend to be very place-based in the South. They have strong kinship ties. They try to stick with their network," said Bobby Wilson, a geography professor at the University of Alabama. While having many native-born residents can lead to strong social ties, it may also lead to "less of a diversity of ideas coming in from other states," said Richard Fording, also of the University of Alabama.
