How Do Affirmative Action Bans Affect the Racial Composition of Postsecondary Students in Public Institutions?

Abstract

This study investigates the associations between statewide affirmative action bans and the racial composition of undergraduate students at public 4-year colleges and universities in five states, that is, Arizona, Michigan, Nebraska, New Hampshire, and Oklahoma. I use the Integrated Postsecondary Education Data System data from 1999 to 2017, and find that despite having few selective postsecondary institutions, public four-year institutions in these five states experienced an average decline of 0.42 percentage points in the enrollment of underrepresented racial-ethnic minority students following bans on affirmative action. Further, the bans also decreased the enrollment of underrepresented racial-ethnic minority students at four state public flagship universities.
