In what state do you have the most chapters?

[oldu]

I thought it would be interesting to see in which states each sorority has the most active chapters. The list is below. Some of the same states are near the top of several groups' lists because they have so many colleges, but some of the others may surprise you. The number after each sorority is the total number of states (plus D.C. & Canada) in which they have chapters. Please note, I could only do the NPC groups as I do not have accurate data on active NPHC chapters.

Alpha Chi Omega 40 California, Texas & Pennsylvania
Alpha Delta Pi 37 Texas, California, North Carolina & Tennessee
Alpha Epsilon Phi 22 New York & Massachusetts
Alpha Gamma Delta 36 Pennsylvania, Alabama & Michigan
