This again is inevitable when doing generic rankings. Other notable issues include that not everyone could even consider women’s colleges, and some of these colleges have things like business or engineering, but not others. And of course exactly how much any of these colleges will cost any given individual is sometimes a large variable.
But in a world where generic rankings exist, I think it is helpful to at least have different generic rankings available, which can then maybe help people reflect on the actual utility of any one generic ranking.
