Yes, it is. Especially when both Columbia and Cornell are on the list. Which one was kicked out of the Ivy League recently?
25% of the schools in one conference being on a list of the top 2/3 of 1% of diverse campuses is hardly worth an “only” claim.
(Side note - this reminds me of a photo I posted once showing how “diverse” my team was. Me, a white male, and 28 Indian males, taken in our Mumbai office. I cringed whenever our firm published our “diversity” claims, given the lack of African-American, Hispanic, etc. HR didn’t appreciate my photo).
