I'd imagine this pattern would depend on locality. For example, I live in CT and went to school in RI. I chose to live at home to save taking out additional loans for room and board, but I wasn't really separated from campus life, or even college towns for that matter (My parents lived by an art school and a state college).
However, were I do to the same in an area with fewer educational institutions per sq. mile, I may not have had that experience.
