<p>^The quoted data doesn’t indicate the total number of applicants of each subgroup who sought admission, nor the relative qualifications of each. Among other possible explanations for the results, Stanford may have received a significantly greater proportion of competitive applications from Hispanic applicants than from Black applicants in the past few years. It may additionally, or alternatively, be the case that Stanford was more successful in getting Hispanic students to matriculate there during the time period in question. In either (or both) cases, the numbers cited above wouldn’t represent the admission of more students of one group “at the expense of” another, as the OP stated. Statistics 101: correlation doesn’t imply causation.</p>
