It's difficult to find statistics of unreported sexual assault under 60%.
The Department of Justice claims 65% http://www.bjs.gov/content/pub/press/vnrp0610pr.cfm
The National Sexual Offender Public Website claims 70% are not reported:

RAINN (Rape, Abuse & Incest National Network) claims 68% of of sexual assaults are not reported:
https://rainn.org/statistics
The National Sexual Assault Hotline can be accessed through RAINN . I find this paragraph from their website very disheartening:
Why Will Only 2 Out of Every 100 Rapists Serve Time?
The majority of sexual assault are not reported to the police (an average of 68% of assaults in the last five years were not reported). Those rapists, of course, will never spend a day in prison. But even when the crime is reported, it is unlike to lead to an arrest and prosecution. Factoring in unreported rapes, only about 2% of rapists will ever serve a day in prison.
Although the stats are dismal there is always hope with public discourse and more education given to this topic at high schools, colleges and universities. I always believe in hope.
