involvement?

All sororities are involved on campus.
the most visible are DG KD and KKG in my opinion.
the least visible are XO AOPi and Pi Phi. Other than a small handful of XOs that want to run for miss ole miss or Homecoming queen you never see these 3 groups or notice any philanthropic events.

DG and KD are most involved. They dominate organizations. And no, I'm not in either but I can admire the hard work they put into involvement. I wish more members of my sorority cared about involvement as much as I do.
DDD and Phi Mu are very involved, lots of organizations but I guess not as much leadership positions or visible girls as DG and KD? Could easily change though.
Kappa and XO are similar (literally in only this way) that they have half of the girls involved in something but not running any organization, and the other half is invisible on campus. The ones involved really carry a lot of weight for the rest though.
AOPi is actually relatively involved, they could make a case for being with Kappa and XO, but their girls are more reserved and tend to not be stand outs in organizations. You don't see them around campus unless you already know they're AOPi because it's not as obvious/in your face as say KD, DG, DDD.
Pi Phi and Theta need to step it up. These 2 as a whole are probably least concerned about campus involvement and yes that contributes to their rank. The handful that are involved are great and trying to bring about some change, but a small number can only do so much.

I feel it's inaccurate to rank ADPi based on involvement at this point since they've only been here a year and haven't had time to get members involved yet, and people haven't had time to realize everyone on campus who is an ADPi.

I could agree with that list and reasoning.

accurate

KD and DDD are pretty much the most active. They REQUIRE participation in many events. DG and Phi Mu are also really active.
