TY - JOUR AB - The 2023 Supreme Court decision Students for Fair Admissions v. President and Fellows of Harvard College (SFFA) effectively ended the explicit consideration of race in college admissions. This paper examines the impact of SFFA on the racial, ethnic, and socioeconomic composition of undergraduate populations across institutional sectors. Using 2018–2024 data from the Integrated Postsecondary Education Data System (IPEDS), I analyze changes in the shares of White, Asian, Black, and Hispanic students, as well as the proportion receiving Pell Grants, state and local aid, and institutional grant aid. I employ a difference-in-differences framework that leverages variation in institutional selectivity and pre-existing state affirmative action bans, incorporating group-specific linear time trends to address differential pre-treatment trends. Results indicate that, among more selective institutions, Black student shares decline while White shares increase, with the largest effects in highly selective private institutions and more broadly across public institutions. Hispanic shares also decline and Asian shares rise, although less consistently. Pell and state aid receipt decrease, suggesting that reduced racial/ethnic diversity leads to less socioeconomic diversity as well.
