One in four college women have survived either rape or attempted rape in their lifetime. The US Department of Justice published a study in 2006 of over 4,000 college women. In that survey, 3% of those women had survived rape or attempted rape in a 7 month academic year, alone. An additional 21% had survived rape or attempted rape at some point in their lives prior to that academic year. When you take those two figures and add them up – the 3 and the 21 – you get 24%, or roughly one in four.
