Okay, so I know most people don't really know or *care* about the Mid-Con conference, even though my alma mater usually does some damage with the men's basketball team
The nine schools in the Mid-Con are:
Centenary
Chicago State
IUPUI
UMKC
Oakland
Oral Roberts
Southern Utah
Valparaiso
Western Illinois
There are 15 NPC organizations represented with 24 chapters open (that I found). Chicago State and Oral Roberts don't appear to have any NPC sororities, and Southern Utah's webpage wasn't opening for me, so if I'm incorrect, please let me know!
The NPC organizations represented are:
Chi Omega at 4/9 of the schools
Alpha Delta Pi at 3/9 of the schools
Delta Zeta, Gamma Phi Beta, Alpha Sigma Tau, and Phi Sigma Sigma at 2/9 of the schools
Sigma Sigma Sigma, Sigma Kappa, Kappa Kappa Gamma, Zeta Tau Alpha, Phi Mu, Pi Beta Phi, Delta Delta Delta, Alpha Phi, and Kappa Delta at 1/9 of the schools
