They ask women if they have ever experienced sex under such and such a condition, or in certain circumstances, and anyone who says "yes" counts as a rape victim for the purposes of the study. In the study that produced the "25% of female college students" figure, over 70% of the "rape victims" did not think they had been raped, and over 40% of them had sex again with the supposed rapist. If you're going back for seconds, either it is not rape, or rape is not a sufficiently serious crime to expend all this bother preventing and prosecuting.
