Sure, but that's a pretty blind metric. "If Harvard (6k undergrads) accepted as many students as Texas A&M (50k undergrads), it would be more diverse!" But then it wouldn't be selective; it wouldn't be Harvard. Presuming Harvard is interested in increasing enrollment at all, that alone doesn't help increase these percentages. If Harvard accepts 1 low-income student for every 10 people, and accepts 100 more people in total, the mix is still 10%. I don't think that's "increased access".
