Diversity at IU has evolved and continues to adapt with the times. While there is still an obvious white majority on campus, the numbers are slowly shifting to include more students from various backgrounds. Everyone is considered equal here, whether you're the only student from your particular background or one of 3,000. Everybody has the same opportunities, and it is up to the individual to go after the opportunities offered.
IU still has a long way to go to catch up with the diversity found in other schools, but the University is trying awfully hard to overcome the single-mindedness of some of the locals here and elsewhere in the nearby Bible Belt. Overall, though, minority students should feel just as comfortable here as anyone would, and there are plenty of organizations to reinforce that feeling.
