Male enrollment and total enrollment was steady, so that's not it.
I can't control for socioeconomic factors, because that data isn't collected (except by financial aid, and I doubt I can get my hands on it). I can see that this could be caused if there was a sudden decline in the average student's wealth- poorer students can't afford to be Greek. I'm going to have to account for that.
It isn't geographic region of students- I've got those numbers, and they don't change over that period, so it's not like we were getting significantly more out of staters.
I'm trying to think of other things that could affect student body composition in a way that would cause this. We didn't get any new dorms. It's possible there was new apartment construction, which might reduce Greek involvement, that's easy to check. No new academic programs. We changed from Div II to I-A in football, but I'm not what affect, if any, that would have on this.
Please don't think I'm upset you're poking holes- I appreciate it, because it's what the people who read my article are going to do as well. Every theory needs a devil's advocate.
