In general, is it more common for college dorms to be co-ed (not necessarily the rooms but the dorm as a whole) or for dorms to be exclusive to one gender or the other?

My D22 is looking at 5 colleges. 2 are women’s colleges, so there’s that. Her #1 school, a small LAC, has pretty much every configuration of dorms including all male and all female as well as themed dorms like LGBTQ and Eco-living and Wellness (substance free).
