<p>Papa:</p>
<p>The USNEWS database has percentage of need-based aid as well. Look under the tab for "financial aid". Also, the USNEWS "white" number includes everyone who has not self-reported as an Af-Am, Latino, Asian-Am, Native Am, or International, so it's an easily referenced "diversity index". Look under the "student body" tab.</p>
<p>Numbers that I have found useful in this kind of analysis are:</p>
<p>Percentage of non-white and non-US students
Percentage qualifying for need-based aid
Percentage of Pell Grant recepients
Percentage of public school students</p>
<p>All of these except the last one are easy to find. In total, they present a fairly complete statistical snapshot of "diversity".</p>
<p>When you find a school that lacks diversity, there are four potential contributing factors:</p>
<p>a) Geographic location. Most college students still go to school within a few hours of home, so the ethnicity of the underlying regional population plays a role.</p>
<p>b) Financial strength. Diversity is very expensive for a college. If the financial structure of a school relies heavily on tuition revenue, the school must emphasize attracting full-fare customers in admissions. This reduces the ability to attract a diverse student body.</p>
<p>c) Selectivity. The higher the academic standards of a school, the more difficult it is to attract a diverse student body (economically and ethnically), simply because poor, non-white students tend to not have high SATs and the like. This highlights how hard the most selective colleges work at enrolling a diverse class and the intense competition for high-stat minority applicants. For example, of the acceptance letters Swarthmore mailed for this year's class, only 45% were to white US citizens. Yet, by the time they battled with other schools over the minority students, 57% of the actual enrolled class was white, US students.</p>
<p>d) Institutional culture. Some schools are just more institutionally committed to diversity than others. For example, Davidson faces many challenges in enrolling a diverse class (endowment, high percentage of full-fare customers, geographic location). However, the fact that they did not change their by-law preventing Jewish or Hindu or Buddhist or Muslim alumni from serving on the board of directors until last year indicates an historically less robust embrace of diversity than some of the other schools on your list. Ways of examing instutitional commitment include looking at the the percentage of minority faculty, the presence of minorities on the dean's staff, and the percentage of minority students in leadership positions (student council, RAs, etc.).</p>
