Honestly, I feel that diversity is lacking at RPI. I would say that we have student from many different places, but there are not MANY students from many different places. I recently read that the Class of 2014 has students from 42 of the 50 states, all four territories (I believe) and from 14 countries. However, only 27% of the students are from outside of the northeast. I tried to find specific numbers for the student body, but couldn’t.
However, the students that we do have from diverse backgrounds are pretty active. We have a ton of multicultural student organizations which you can see here: http://home.union.rpi.edu/landings/view/1# . I would say many, but not all, of them are active.
