Nationally, reports of forcible sexual offenses on campus rose from 3,443 in 2011 to 4,062, according to the Education Department. In New Jersey, the figure rose from 78 in 2011 to 83 in 2012, the most recent year available. That's because of increased reporting of crimes due to a culture change and greater support for victims, said Paul Shelly of the New Jersey Association of State Colleges and Universities. Indeed, only 13 percent of victims of forcible sexual assault reported the crime to police or campus authorities, according to a 2007 National Institute of Justice study.
