Research has shown that by the time they graduate, as many as one in three women and almost one in six men will have been sexually assaulted. Why is sexual assault such a common feature of college life, and what can be done to prevent it? Drawing on the Sexual Health Initiative to Foster Transformation (SHIFT) at Columbia University, the most comprehensive study of sexual assault on a campus to date, Jennifer S. Hirsch and Shamus Khan present an entirely new framework that emphasizes sexual assault’s social roots, based on the powerful concepts of ?sexual projects,? ?sexual citizenship,? and ?sexual geographies.? Empathetic, insightful, and far-ranging, Sexual Citizens transforms our understanding of sexual assault and offers a roadmap for how to address it.
