Diversity has been a favorite buzzword at American colleges for decades, and calls to make it a reality have recently reached a fevered pitch.
Across the country, student protesters have demanded that administrators do more to oppose racism and bias. In response, some schools have agreed to drop traditional course requirements in favor of diversity classes, or to require a diverse and inclusive attitude to be a factor in a professor’s consideration for tenure. Meanwhile, Bernie Sanders campaigned on a promise to make college education free and therefore more accessible.
As diversity in higher education becomes increasingly emphasized, we were curious about just which schools have the most diverse student bodies.
Using data from College Scorecard –in a partnership with data-titan Priceonomics— we looked at the makeup of each school’s student body by race/ethnicity. We classified the level of diversity using the Herfindahl-Hirschman Index (HHI), a calculation that is used to measure diversity in a variety of settings–such as the competitiveness of a business market or the biological makeup of an ecosystem.
The index ranges from 1 (the least diverse: a population of all one type) to 1/N (the most diverse), where N is the number of different categories being analyzed. A student body that is entirely White would have an HHI of 1. A student body that is equally made up of people from five different racial groups would have an HHI of 0.2.
To quantify the ethnic/racial diversity on college campuses, we used five racial/ethnic categories identified in the government’s College Scorecard data: White, Black, Hispanic, Asian, and Other. (The Other category includes anyone who identified as more than one race/ethnicity, a race/ethnicity not included in the list, or did not identify their race/ethnicity.) We excluded any colleges that were not geared towards undergraduates, had fewer than 500 students, or for which the College Scorecard did not have data on the racial composition of their student body.
We then created an index for all schools. A lower index number reflects a more diverse student body.
We found that universities in California, like Stanford, UCLA and UC-Berkeley have particularly diverse student bodies, while schools in the Midwest are typically less diverse. Stanford University, the top school in terms of diversity, is three times more diverse than the lowest ranking schools like Yeshiva University and SUNY Environmental Science and Forestry.
The Top 100 Universities Ranked by Diversity
We also found that larger universities tend to have more diverse campuses than smaller colleges, and that the very best schools, as rated by U.S. News and World Report, tend to be particularly diverse.
We began our examination of campus diversity by looking at universities ranked in the top 100 for academics by U.S. News and World Report. Schools are ranked from most to least diverse by HHI.
The 100 Largest Universities Ranked by Diversity
Stanford, with an HHI of .249, has the most equal mixture of racial/ethnic groups of any top 100 school. Clemson, SUNY College of Environmental Science and Forestry, and Yeshiva University receive the lowest diversity scores; they are predominantly White. In fact, almost every school ranked near the bottom in terms of diversity has a predominantly White student body.
The University of California (UC) campuses are particularly diverse by HHI, accounting for seven of the top twenty most diverse colleges in this ranking. The California schools have high percentages of both Asian and Hispanic students, which fits the historical trend of immigration to the Golden State. UC-Irvine ranks twentieth overall, but has the lowest overall percentage of White students at 17%.
Next, we measured diversity by HHI for the 100 largest universities by student population in the United States. Thirty-one of these schools were also listed U.S. News and World Report’s top 100 list.
The Top 100 Colleges Ranked by Diversity
Notably, California State University-LA (HHI = .404, ranking #41) is the only school in this ranking to actually perform worse on diversity due to a lack of White students. Just 8% of the California State University-LA student body identifies as White.
Overall, the 100 largest universities are less diverse than the U.S. News and World Report’s top 100. The median score for a top 100 university was .395, whereas the median score for these 100 largest schools is .451.
Finally, we examined diversity at liberal arts colleges. These small colleges are often known for being ethnically homogenous. We wanted to know if the data would support this notion. This next chart displays the diversity numbers for the U.S. News and World Report’s top 100 liberal arts colleges.
The 100 Most Diverse Schools (All Universities)
Out of the top 10 most diverse liberal arts colleges on this list, four of them are all women’s colleges (Wellesley, Bryn Mawr, Smith, and Mount Holyoke). This trend may seem surprising, but it is supported by these school’s founding ideologies. Women’s colleges were created to provide education to those who were normally barred from the ivory tower, and although this initially meant women, administrators applied the same inclusive attitude to admitting minorities.
These rankings call tell us which colleges have diverse student bodies, but it can’t tell us which colleges are achieving all their diversity goals.
Diversity has more meanings than just racial background, and admitting a diverse student body does not guarantee that a college will also hire a diverse faculty, create a supportive environment, and meet expectations for a diverse curriculum.
Yet for college applicants wondering whether colleges’ glossy brochures, which feature smiling groups of racially diverse students, actually reflect reality, these rankings are a guide. Students who prize racial/ethnic diversity as part of their education should look at larger universities, especially those in the University of California system. And students seeking a more intimate setting should consider standout liberal arts colleges like Amherst, Swarthmore, and America’s women’s colleges.
