If the goal is to resegregate higher education, the efforts have largely worked. Amid budget cuts and attacks on affirmative action, elite public colleges are enrolling fewer black students than they were a generation ago. In a new report, “Social Exclusion: The State of State U for Black Students,” I take a look at the enrollment of black students across 67 selective public institutions—including each state’s flagship campus and other very selective public institutions like UCLA, Georgia Tech, Clemson, and William & Mary—across the past 20 years. I found that nearly half of these schools are enrolling a lower percentage of black students than they were in the mid-1990s. Nationally, one in six college-age people are black, but there is only one African-American among every 20 students at large, elite public schools.
