For economic diversity, a respectable 21% of UMD students are Pell Grant recipients. 14% of Vandy students are Pell Grant recipients, sandwiching it between elite public universities like UVA (12%) and Michigan (15%).
Vanderbilt wins handily in geographic diversity. 90% of students are from out-of-state, and 63% come from outside the South. Only 23% of Maryland students are from out-of-state.
The two are pretty comparable in racial/ethnic diversity.
