^^ I agree that you really can’t make any real judgments from my 32 data points from CC. However, every year The Journal of Blacks in Higher Education posts an interesting chart about African American acceptance rates at various colleges vs. the overall acceptance rate: https://www.jbhe.com/2016/01/black-first-year-students-at-leading-research-universities/
Depending upon the college, being a URM can boost an applicant’s chances, but by how much depends on the school. For example, at Cornell, the African American acceptance rate was 17% vs the overall acceptance rate of 15%. At the University of Chicago the African American acceptance rate was 10% vs the overall acceptance rate of 8%. However, at Northwestern, the African American acceptance rate was 23% vs the overall acceptance rate of 13%. So a URM’s milage will vary depending on the school.
