<p>I don’t think the college has any way to distinguish between ‘living at Mom’s house’ and ‘living in an apartment across the street’. I think what you’ll need to do is some inference by seeing how many students live on-campus, which years those students typically are (ex: maybe most are first 2 years only), how many students are enrolled in those approximate years. You should be able to get this detail from the college’s website. This’ll give you a good idea of how many students moved out of Mom’s house to go to the college.</p>
<p>If a campus limits its on-campus housing to only the first 2 years, as an example, then there’s a good chance that after that point the students move off campus to adjacent and nearby apartments which are virtual dorms and although classified as ‘commuter’ at that point there’s little difference between living in the nearby apartments and living in the on-campus dorms so the term ‘commuter’ in this case is misleading. Some colleges have pretty well-developed private apartments nearby that are occupied mostly by students. You can usually see this if you visit the campus area (or Google street view the area).</p>
<p>Another factor is just the number of students living on campus regardless of the percentage. I think once the number hits a certain point, even if the percentage is smaller, there’ll be enough there to afford a decent ‘on campus experience’.</p>
