ALLEGEDLY
apparently the Congo alone might account for that
A US report says 48 women and girls are raped every hour in DR Congo, a rate significantly higher than a previous UN estimate.
www.bbc.com
If an average rape lasts even as little as 2 minutes then 48 per hour definitely makes it 24/7 in the Congo.
Worldwide that'd probably be at least a dozen or even a score or 2dozen/2score rapes per hour. Maybe hundreds.
Of course you also have underreporting (women too scared to report) and overreporting (women making false accusations) that are going to fuck with the accuracy.
