Most Diverse Colleges
Colleges ranked by balance across eight stored race, ethnicity and international-student share categories
What this ranking measures
The score measures balance across eight stored race, ethnicity and international-student share categories. It is a normalized Simpson index from 0 to 100; a higher score means the reported shares are distributed more evenly across those categories.
Eligibility requires at least four positive known categories, at least 80% known coverage, no more than 20% unknown share, a reported total between 90% and 110%, and positive enrollment. Unknown share affects eligibility but is not counted as diversity. This metric does not measure inclusion, campus climate, socioeconomic diversity or an individual student's experience.
Methodology and source limits
Normalized Simpson balance index across eight known student-share categories; unknown share affects eligibility but is not scored as diversity. Source periods can vary by field and institution. Missing values are not proof of zero, and these lists are not universal judgments of educational quality.
Tie-breakers are known demographic coverage, then total enrollment, institution name and slug. The formula is 100 × (1 − Σp²) ÷ (1 − 1/8), where each p is a known category's normalized share.
