As college students explore their campuses, they're likely to find a wide array of student groups that pertain to race: The Black Student Union, Asian-American groups, or Hispanic and Latino groups.
Universities say they're spending time and money on trying to increase the number of minority students, especially since the Supreme Court ban in 2006 on affirmative action.
But Ron Haskins of the Brookings Institution says the challenges for American colleges should be not only racial diversity, but also economic diversity.
Especially when universities, including elite schools, haven't upped their percentage of low-come students in generation.
Haskins says that's what happens when colleges maintain admission standards.
