Rust College is a historically black college, so the student body is predominantly black. However, there is a small percentage of Caucasian and Hispanic students that attend the institution. To broaden things up, Rust could use more ethnicity, but that might defeat the purpose of Rust being an HBCU.
Anyone of any race or gender can attend Rust, as there is no discrimination, but most African Americans choose to attend. And in terms of gender, more women than men attend Rust. Overall, though, everyone comes from different backgrounds.
