My question would be this: Do these statistics show "new" chapters among the statistics.
What I mean is that when I return to Ohio University, there are some houses that weren't there when I was a student way back when.
So, do the statistice identify new groups that have failed as well as more established ones?
There can be a number of reasons for a chapters failure -- not always having to do with relative strength of the system as a whole on campus.
Specifically, in terms of OU, the "new" president (of about three years) is a BGLO member, whereas the former president was not particularly supportive of GLO's.
Also, when was the list compiled.
Here's a link to a list of active GLO's and Colonies at Ohio:
