<p>In terms of racial diversity, I would encourage you to also consider the number of minorities in leadership and teaching positions. Also consider if the deparment(s) you are planning to study is diverse, not only in terms of race, but also in terms of academic background and research/published material/etc. Additionally, if diversity is important to you, then you should also consider the support system that’s in place. If you have specific target schools, seek out different types of students and ask about their experience at the school, if they would encourage you to attend, etc. Regardless if a school is or is not diverse in a statistical sense, statistics won’t tell how the students interact with each other, if it’s a comfortable or tense atmosphere, etc</p>
