A summary of the numbers from all the surveys and studies I’ve taken note of in this thread is below, ranked from highest to lowest rate for similar events. Note the wide range of different numbers and different survey conditions. Some common sources of variation including number sample group (for example 1st year vs 4th year, or college A vs college B), types of incidents included in reported total (for example without consent via “continual arguments and pressure” rather than force or incapacitation), and wording of questions (vague wording like “sexual assault” leads to underrporting).
