@theloniusmonk that’s admitted students, not enrolled. As I read it, anyway.
However Columbia says 14% black under the heading “Demographic Information for the Class of 2019” which should mean enrolled students. Just the one class though, still.

12% here, for first years: http://www.jbhe.com/features/61_enrollments.html <-2008 though
But “two or more races” and “other” can mess things up a bit also.
If the Ivies are in the single digits, not even high ones, I’m surprised. I thought they were all over 10% like Amherst
