<p>If you look at the % of freshmen who live on campus, that will give you somewhat of an idea as to the make up of the school. The overall % is not as helpful because there are schools where a lot of kids go off campus after freshman year. </p>
<p>The other thing that matter is the absolute number. If the school has 20,000 students even if 80% tend to live near enough to go home regularly, you are still talking about 4000 students hanging around which makes for a sizeable core. A school 10% of that size has numbers that can really affect getting any kind of student life going.</p>
