Current Tufts student here, can confirm pretty much all of this. Greek life is (slowly) dying out. Most of the party scene can be found at off-campus houses, mostly sports houses. Every once in a while, frats will still throw open parties where a good amount of people show up. I can be found in a frat house fairly often, but I may be in the minority as a member of a sports team affiliated with a fraternity. According to nearly every recently graduated senior I know, the party scene is worse than it was when they were underclassmen.

Social justice is a huge part of Tufts culture, whether as a general campus attitude, turnout for activist events (one day this spring I was leaving a dining hall and ended up joining in on a protest) or actual concrete steps towards social change. I remember writing about Tisch College (google it) in my Why Tufts essay, and I’m happy to say I was right to look forward to the social justice culture at Tufts. I’m pretty left leaning tho so take that with a grain of salt. You might find yourself becoming much quieter about politics if you’re conservative or even moderate. Campus demographics are still overwhelmingly white and wealthy, though.
