Unfortunately, Auburn University is not the multicultural hub that some think it is. The majority of students are overwhelmingly white, with just a fraction of minorities. Don't let that intimidate you, though. Auburn students all claim to be right at home in Auburn and praise the efforts of the administration to help diversify the University.
AU offers many different organizations that cater to almost every type of person and background. Of course, there have been incidents in the past concerning racial and political issues. You should do thorough research on these issues before deciding on a school. Tensions between majority and minority groups are not frequent at all, but cases do arise sometimes. Auburn has a welcoming and friendly atmosphere, but as with any school, it's best to visit the school before making a decision to see if you think you'll be happy.
