In the financial aid section of a college’s description on College Navigator (feds’ website based on IPEDS data), it will indicate what percentage of students receive a Pell grant (or other federal grants) which might give you an idea of the kind of socioeconomic diversity a campus might have.
Of the schools already on your list to explore:
- Clark: 19%
- Muhlenberg: 21%
- Ursinus: 18%
- Wheaton: 20%
For some of the schools that have been mentioned, these are the Pell percentages. I bolded the ones that were at least 18% (the lowest from your list of Ursinus). I also added Brandeis & College of the Holy Cross to the list:
- American: 10%
- Bates: 9%
- Brandeis: 14%
- Brown: 14%
- College of the Atlantic: 29%
- College of the Holy Cross: 16%
- Connecticut College: 15%
- Dickinson: 12%
- Fordham: 23%
- Goucher: 27%
- Hamilton: 22%
- Skidmore: 12%
- Sarah Lawrence: 10%
- Susquehanna: 23%
- Tufts: 12%
- Vassar: 19%
- Wesleyan: 13%
- William & Mary: 12%
- Williams: 14%
Looking at the percentages for any other schools you choose to explore might help give you a sense of how your son might feel about the financial dynamics with the student body.
