Penn is a pretty diverse place, with attendees from places like Kenya and Switzerland as well as across the country. Racially it is also diverse, but Caucasian students are the majority--and many of them are Jewish. The campus is overall friendly to different nationalities, ethnicity, and sexual orientations; most have specific groups on campus for members to gather if they wish. The most underrepresented groups are Native American Indians, African Americans, and Hispanics, but their presence on campus is still visible. Many Penn students do come from affluent backgrounds, and some students may find that extracurricular activities strain their budget. There is some self-segregation, facilitated by campus groups with a special focus (Black Whartonites, Chinese a Capella, Indian dance, etc) but also interaction between different people. Classes, dorms, and other groups serve to bring different people together, so the interaction is as extensive as students want.
Penn students are generally well-put-together, but are hardly formal for classes. There is always a fair share of PJs/sweatpants, especially during crunch times, but there is not an overwhelming style that dominates.

I studied amongst a diversity of affable students that came from wealthy, educated origins.

The typical Penn student is white (or Asian), upper-middle class, and from a suburban public high school on the East or West coast of the US. Many people are on financial aid of some kind, including work-study. There is little to no socio-economic snobbery; Penn tuition is a substantial expense for all but a tiny number of students.
The financial aid rules leave a window of well-to-do students who are ineligible for work-study but still short of cash, and many of them work in the cafeteria ("dining services"), which is a non work-study job. They include some foreign students who are absurdly wealthy in their home countries but work for spending-money during the school year.

My peers at the University of Pennsylvania inspired me to think creatively and challenge everything I thought and knew; each person I met was unique and I learned a little bit from each person. It was like opening a giant box of crayons and seeing all of the different colors, each one brighter than the last. It was intimidating, at times.

Many people here are relatively humble given their exceptional backgrounds., with the person next to you in line or in class most likely fitting one of these descriptions: valedictorian, athlete, entrepreneur, genius, hard worker, among others; but don't imply from friendly smiles that they will hold back from you in competition.
Elizabeth
Highly focused, academically accomplished, many from very affluent families, well connected, very diversed in ethnicity, from all over the world.
