You could take a look at my alma mater, the University of Maine. They currently have 7 sororities and 17 fraternities, with 10 closed chapters. All the fraternities have houses. Most of the sororities do not, and I don't believe they get houses unless a fraternity leaves. Alpha Omicron Pi occupied one of the now inactive fraternity houses (I think it was Tau Epsilon Phi if I remember right) for a few years but they are back in their chapter room in Penobscot Hall. Chi Omega currently has a house but they are the only sorority that does.
What is really surprising to me is that Delta Delta Delta and Alpha Chi Omega are no longer there. I have no idea what happened because they were popular when I was in school.
