The University of Oregon prides itself on having a diverse campus, yet white students clearly make up the majority of the population—over three-quarters—and most minority students are either Asian or Pacific Islander. Only about 20 percent of the total student body in recent years has come from a non-white background. While this rate of diversity is lower than that of the United States as a whole, it is in line with the population of the state of Oregon, and native Oregonians will probably not be surprised. This is typical of the Pacific Northwest.
Although you'll be faced with a fairly homogenous ethnic population if you find yourself at UO, the saving grace of the school is the liberal atmosphere both on campus and in the town of Eugene. Students say that they're exposed to people from many different walks of life, and the atmosphere is characterized by acceptance and tolerance of others. You probably won't find a lot of discrimination based on race, sex, religion, or other personal differences during your time at UO.
