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?

D20 attends a school that employs what they call “gender inclusive housing”. Their description is students can live on campus with whomever they choose, regardless of biological sex, gender, gender identity, or gender expression. Her floor last year was mixed gender floor with 3 bathrooms (one communal male, one communal female, and one individual). This year she lives in a suite that is mixed, mostly because a gay friend felt more comfortable living with females. Options exist for pretty much anything.
