Social Atmosphere at these schools?

First of all there is no “typical student”. Every college on your list will have a wide cross-section of students and every student will have a different take on a school. .

With a list this big try to look at books like Fiske, Princeton Review, Insiders Guide to get some ideas. Then I’d try to visit schools you are interested in to get a first hand view. You need to figure out what you are looking for in a college. The schools you listed all have the common denominator of being fine colleges, but other than that you are all over the map…LAC/mid-size university/large university… urban/suburban/rural…non-sectarian/Jesuit.
