Random roommate selection at the U

Does anyone know if the random roommate that the U assigns you for freshman year (if you don’t find one beforehand) is usually in the same college as you? Or is it truly random? It’s not important at all, I was just curious about this.

You could ask housing. My daughter is in CLA and was assigned to a Carlson student in the German LLC. There was an odd number of students in the LLC, the students were in doubles, and so one more student had to be assigned to the room with the last German LLC student. My daughter is a Spanish major in CLA and does not speak German. I suspect she ended up in the room because she applied for housing on the first day that housing opened. My understanding is that the LLC students are assigned first and then the students are matched in order of housing application. She did get her first choice in housing.
