will there ever be a new NPC member?

I counted based on the "black" chapters on Irishpipes list, so it doesn't include anything beyond this spring. Here we go!

Chi Omega 178
Delta Zeta 161
Alpha Phi 161
Kappa Delta 154
ADPI 150
ZTA 163
DG 146
Kappa 141
Tri Delta 138
AChiO 136
Pi Phi 136
Theta 134
Gamma Phi 131
AOPi 132
AGD 122
AXiD 123
Phi Mu 120
Sigma Kappa 113
Phi Sig 109
Tri Sigma 107
ASA 89
AST 89
DPhiE 89
SDT 58
Theta Phi 55
AEPhi 52

I thought it was also interesting to see the concentration of some sororities. The sororities represented in the most states or provinces (including DC) are

DG in 46
Theta, Kappa and Pi Phi in 45
Alpha Phi in 44
Chi Omega in 43
AGD in 41
AXiD, AOPi, AChiO and DZ in 40
ADPi,Tri Delta and KD in 38
Gamma Phi in 37
Sigma Kappa and ZTA in 36
ASA in 31
Tri Sigma in 29
Phi Mu in 27
AST in 26
Phi Sig in 24
DPhiE in 23
AEPhi in 22
SDT in 18
Theta Phi in 16

I also looked at which sororities are the largest regionally. These sororities have an average of 4 chapters or more per state or province:
Gamma Phi (4)
DZ (4)
ZTA (4.7)
KD (4.1)
Phi Mu (4.4)
Phi Sig (4.5)
Chi O (4.14)

And just to be clear, this is not stating anything approaching which sorority is best or even the largest. This only says how many currently active chapters a sorority has.

eta/feel free to post corrections. Thanks Just interested! But I won't add new additions. I'm not Irishpipes!
