At my school (MIT), we have:
5 sororities
5000 undergrads, about 40% of whom are women
About 150 women rushing in any given fall
Chapter total of 80
Quota between 28-31
4 sororities are consistently close to or over total after formal fall rush. The fifth (AEPhi) is much smaller - I think there are around 30 active sisters right now.
Usually 3 of the 4 big sororities make quota and the 4th gets around 25 new members; and AEPhi gets between 7 and 12. AEPhi also generally gets 1 or 2 new members through informal spring rush.
I simply can't get my head around the idea of a chapter total of 230 and new member classes almost as large as our chapter total. I deliberately chose not to join one of the "big 4" in part because I thought I would get lost. Imagine having 70 *pledge sisters*. Wow.
