Sororities more common in one area?

[IowaHawkeye]

i would have to disagree - while it may not hold true for all sororities, where youre founded and where youre heavily concentrated could be related because the closer you are to nationals, the more suport you could recieve from them and all of the alumnae that are in that area. Of course all of the chapters that were established there may ceases to exist b/c chapters close for reasons beyond anyone's control.
