body is international, representing 126 countries. In graduate and professional student population, non-Indiana residents occupy an overwhelming majority, about 75%. Almost all undergraduates and about 70% of the graduate student population attend full-time. The school's selectivity for admissions is "more selective" by USNWR: approximately 49% of applicants are admitted. Housing About one-third of the single undergraduate students on the West Lafayette campus live in university-owned buildings. The rest live in fraternities, sororities, cooperatives, or private off-campus housing. There are 11,844 spaces available for undergraduate students, graduate students, and student families who choose to live on campus. Sixteen percent of the undergraduate student body are members of the 40 fraternities and 20 sororities on campus. Purdue University operates seventeen separate residence halls for its undergraduate and graduate students, including Cary Quadrangle, Earhart Hall, First Street Towers, Frieda Parker Hall, Harrison Hall, Hawkins Hall, Hillenbrand Hall, Hilltop Apartments, Honors College and Residences, McCutcheon Hall, Meredith Hall, Meredith South Hall, Owen Hall, Purdue Village, Shreve Hall, Tarkington Hall, Wiley Hall, Winifred Parker Hall, and the 5 Windsor Halls: Duhme, Shealy, Warren, Wood, and Vawter.

There are 12 cooperative houses at Purdue (five men's houses and seven women's houses). The men's houses include Circle Pines, Fairway, Marwood, Chauncey, and Gemini. The women's houses include Ann Tweedale, Glenwood, Twin Pines, Maclure, Stewart, Devonshire, and Shoemaker. All cooperative houses are governed under the Purdue Cooperative Council which is led by Purdue University students who live in these houses. The cooperative system allows for a much lower cost of living than other types of housing, averaging $2900 annually with all-inclusive monthly rent ranging from $250–$625 varying by house. The members take an active role in sharing chores and cooking all meals themselves, as opposed to hiring out cleaning and cooking staff. Purdue University hosts one of the nation's largest Greek community, with approximately 6,000 students participating in one of the roughly 40 men's fraternities or 30 women's sororities. Several of Purdue's most distinguished graduates are members of fraternities and sororities. Purdue's Greek system is very strong and works together in various aspects, including the Inter-Fraternity Council, Panhellenic, and many very successful philanthropies. Every chapter has national philanthropy dedicated to a certain cause that many chapters also participate in. Besides philanthropy,
