Brigham Young University (often referred to as BYU, or sometimes just the Y) is a private university located in Provo, Utah. It is owned and operated by The Church of Jesus Christ of Latter-day Saints (LDS Church), and is America's largest religious university and fourth-largest private university. Approximately 98% of the university's 34,000 students are members of the LDS (Mormon) Church, and one-third of its American students come from within the state of Utah. BYU students are required to follow an honor code, which mandates behavior in line with LDS teachings (e.g., academic honesty, adherence to dress and grooming standards, and abstinence from extramarital sex and from the consumption of drugs and alcohol). Many students (78% of men, 10% of women) take a two-year hiatus from their studies at some point to serve as Mormon missionaries. Many BYU students speak foreign languages during their Mormon missions, and approximately 31% of the student body enroll in foreign language courses, making it one of the most linguistic universities in the United States.
