— About 90 percent of rapes occur between people who already knew each other.
— A 2001 study by the Bureau of Justice and National Institute of Justice found that about 3 percent of college women experienced a completed and/or attempted rape during the current college year.
— However, many claim less than 5 percent of completed and attempted rapes were reported to law enforcement officials. In about two-thirds of the rape incidents, however, the victim did tell another person about the incidents.
