H wants to be a good “Boston neighbor.” There are a lot of alumni and fac brats in the area. And, of course, their overall applicant pool is skewed to the northeast. You simply don’t know whether they “over favor” or “under favor” Massachusetts kids. Ditto, by the way, for Oklahoma kids. You don’t know if they over favor or under favor them either, just because relatively few are at H. It could very well be a function of how many / few applied.
