Lehigh is currently trying to expand diversity. Right now, the majority of students are white males. The male to female to ratio when I applied was somewhere around 60:40. Lehigh is working to balance that out. Lehigh is also working to attract more diverse applicants with things like Umoja house, which is diversity housing, and I believe there is some sort of Islamic Studies facility in the works for years to come.
I personally have not had any experience with Lehigh's LGBT population, but I am familiar with a place called the Rainbow Room, where LGBTQA (Lesbian, Gay, Bisexual, Transgender, Questioning, Ally) students can go to feel safe and accepted should they ever feel otherwise. Many offices around campus also display the pink triangle sign, which means that the room is a safe zone for LGBTQA students if they ever need someone to talk to. There are also counseling services freely available in Johnson Hall, which is our Health Services headquarters. Another great feature at Lehigh is a group called Break the Silence, which is a student organization that exists to help students of all sexes, races, religions and sexual preferences. Break the Silence runs a hotline that students can call should they ever feel depressed, scared or oppressed and also if they were sexually violated in some way. Break the Silence is an invaluable part of Lehigh's community, a safety net for students should they ever feel alone or if something bad happens to them.
Most of the students I have met are from New Jersey, Pennsylvania, New England or Long Island. There is also a surprising (to me, anyway) number of Californian students as well. Lehigh is also host to a large population of international students. I have met students from Vietnam, Malawi and Jordan, and those are only the girls on my floor!
Based on the people I know, most Lehigh students come from middle- to upper-class backgrounds, but Lehigh is also very good about giving financial aid to those who need it. I have heard many students talk about money and how much of it they hope to make someday. I met one guy at the beginning of the year who said he wanted one house on the beach and another in India! He said he would have servants and everything. I would be lucky to get an apartment that didn't have water damage and some kind of infestation, but that doesn't really bother me. I honestly don't know how much the average journalist makes, but I'm willing to bet it's not enough for a mansion in New Delhi.
Students here are politically active on both sides of the political spectrum, though I would have to say that Democrats outweigh the Republicans by a decent margin. The political groups on campus are always active, hosting talks and events to raise awareness. Presidential candidate Barack Obama has a particularly active following here. Students for Barack Obama had tables set up all over the place, getting people to register to vote in the Pennsylvania primary.
