campus overlap
 

OK, I know this is a weird question.

Has anyone done any kind of analysis to see if certain sororities tend to have chapters at the same campuses? For example, I'm guessing that AXD shares campuses with more chapters of Chi Omega than Sigma Delta Tau, but only because Chi O is larger - I haven't looked at the numbers.

I'm looking for something like, "If there is a KKG chapter on campus X, there is an X% probability that there is also a Tri-Delt chapter, but only a Y% probability there is an Alpha Xi Delta chapter."

Yeah, I'm way too lazy to do the research and build a database, so I was wondering if anyone else had this kind of data.

just from my observations, if there is an ASA chapter on campus, there more than likely will be a chapter of AST, Tri-Sigma, or both. it's the AES thang :D

I've noticed that Delta Phi Epsilon, Theta Phi Alpha, and Phi Sigma Sigma tend to be at the same campuses.

I agree with 33girl. Since AST isn't part of a "duo" or "triad", we got the "AES thang" going on!!

I would say that NPC would have the raw numbers (i.e. ABC, DEF, GH are on campus 1; ABC, GH, XYZ are on campus 2) but you would have to do the statistical formula probably. Dunno though, NPC may have actually done this in the past.

If you get any numbers from NPC let me know. I'm interested in looking at the data myself!

I'm also way to lazy to figure that out and even if I wasn't math is not my thing.

I had a similar question along those lines: Which sororities are in which tier, who has the most memebers. Basically stats nationally. I tried searching and I only come up with indvidual campuses.

Is there a web site with all of this on it, I tried www.npcwomen.com but couldn't find it there.

what is meant by the term "tiers"? i have heard it several times on GC

About overlaps...

...I've noticed that many schools that have or have had a chapter of Alpha Chi Omega tend to have a chapter of Kappa Alpha Theta, or vice-versa. I don't think it can be attributed to DePauw, though.

The only time I've heard "tier" regarding sororities is related to their "ranking," either nationally or locally. I hate tier talk--in my mind there is only one tier, and there are 26 sororities tied for first place. What can be the top house in one school can be the "worst" house in the school down the street.

Observation: If a school has Kappa, then it will likely have Pi Phi and/or Theta.

If a school has a D Phi E, it is more likely to have a Phi Sigma Sigma too. At least in my experience, but that's not always true :)

If you go to Ariesrising's site you can find a listing of chapters and numbers, but they aren't guaranteed to be accurate.

This same thing has occurred to me before, but I didn't really give it much thought. My school had no Phi Sigma Sigma, Theta Phi Alpha, ASA, AST, or D Phi E...however, we did have Kappa, Theta, and Pi Phi (as per KappaKittyCat's observation). I don't know where you'd get any statistics about this, but I'd like to see them just for the heck of it.

Thanks, it was very interesting, not necessarily accurate

I don't think we could really get accurate numbers - even if you called an IO to get a number of initiates, you don't know how many of those have deactivated. I think the most important statistic would be the percentage of active members, active meaning financial and involved. I don't care if you initiated 300,000 people if only 10,000 are active, but if you initiated 30,000 people and 10,000 are active, you're doing something right.

My school has all three! (Out of five sororities - the other two are Gamma Phi Beta and Alpha Phi)

Alpha Phi and ADPi seem to be at the same campus on a lot of occasions.

I notice SAE and Sigma Chi tend to be at the same campuses, same with Delta Sig and Theta Chi.
