There is large amount of gender and sexual diversity (majority female students, probably a large number who identify outside of the binary system that the statistics do not cover). Much art and discussion and politcs is devoted to this; I am a very left-wing person so I am completely cool with this stuff. Religion is rarely discussed, mostly atheist/agnostic if I am a reliable observer. Among American-born students the vast majority seem to be white and from suburbs/wealthier regions of liberal metropolises (New York, Seattle, Chicago, etc); there are a lot of international students, mostly from East Asia but also Europe and Latin America (most spanish speakers seem to be international rather than American Hispanics like me).
Where the school fails miserably is in economic background; I'd estimate the median income for a student's household to sit no lower than $80,000 a year; class is not really discussed as much, the school benefits financially from being closely aligned with both industry and the aflfuent families of suburbia and gentrified neighborhoods across the country. Positively, it seems possible to make friends despite class boundaries anyway, but it affects the art-making and the ability to go out often.
