Play around with the year/school. Clicking on data points shows self-reported profile information. It's pretty clear there is a shifted standard in many cases.
Yes, they do. The university I attended for undergraduate studies, Tulane in New Orleans, had a minor blowup when I went there because they were very much trying to make the school less lilly white and explicitly declared they had a pro-diversity admissions policy. Now they can do whatever because it's a private school, but it was still very controversial. It was actually heavily based on the Yale policy.
