What do you mean by “black people”?  Are you referring to all people of African descent, or just some particular group of them?  Do you mean people who look black or dark-skinned, or who identify as black, or people who have some ancestry that’s mostly African?  Are you using the word “black” in the way it’s used in media about the African-American population?

Is the primary issue that you have here with the people who are the main focus of this phrase?  In other words, do you want to understand why they aren’t in college, or why people aren’t in college, or what the academic reality is for people of African descent?
