Sexual assault is a serious concern on college and university campuses across the United States. However, the institutional factors that may make campuses more or less prone to rape are poorly understood. This study utilizes routine activities theory (RAT) to examine campus-related factors across 524 four-year campuses in the United States to determine what features of a campus community are most closely associated with increased reports of sexual assault. Results suggest that the type of athletic program, the number of students who live on campus, and the institution’s alcohol policy were all found to be related to reported sexual assaults. Implications for understanding campus communities and prevention of sexual assaults are discussed.
