<p>The overwhelming majority of kids attend college within a 5 hour drive of home. Convenience, cost, familiarity and lots of other reasons for that. So it is pretty DUH obvious that Stanford will have more western kids and Harvard more northeast kids. </p>
<p>The correct way to look at this would be to compare Harvard’s geographic distribution to that of other colleges located in the NE region. From this perspective, Harvard would look massively more national and less parochial as compared to, say, UMass or Northeastern.</p>
<p>It would be highly unusual for any school to not have some amount of over-representation from its home region. To get an even spread, the school would need a few characterisitcs. First, it has to be private to avoid the in-state tuition effect. Second, it needs to have a brand and other features (reputation, specific academic programs, price/value proposition, etc.) that makes it worthwhile for remote kids to apply and enroll. Why go 1,000 miles away when you can get the same thing at the same price 100 miles away? Third, the school has to be located in a region that does not produce a high volume of kids that match the demographics of the school’s enrolled population.</p>
<p>From that list, I’d guess schools like the following would have less regional enrollment than most: Duke, Vandy, Tulane, West Point, Annapolis.</p>
