Federal data and new analyses show the Supreme Court’s 2023 rulings on affirmative action reshaped where underrepresented minority students enroll. Class Action’s report and federal figures found Black and Hispanic freshman enrollment fell sharply at the most selective private institutions but rose at many public flagships and less selective colleges — a 'cascade' effect as students redistribute across the higher‑education ecosystem. The pattern is pronounced at Ivy‑Plus campuses, where Black freshman enrollment dropped markedly, while institutions such as the University of Michigan and several state flagships saw sizable gains. The shifts are prompting admissions, financial‑aid and student‑support adjustments statewide as institutions respond to changing applicant pools and equity implications.
