This information was taken from the most recent edition (2002) of
Son of the Stars the pledge manual for Beta Theta Pi. It was current probably as of the end of the 2001-2002 academic year. Obviously the numbers have inevitably gone up slightly but again it is very current. I apologize right now for the difficulty in reading this, but previous posts of this material hasn't accepted formating either. see this list on another
post.
The fraternity with the most chapters is Tau Kappa Epsilon with 279. The fraternity with the most members is Sigma Alpha Epsilon at about 248,000 members.
Largest sorority based on both chapters and members is Chi Omega with 174 chapters and about 225,000 members.
I'm not even going to try to figure out most members per chapter...sorry OPrime.
