25% of South African women said they had been raped, but the study notes that only about 1 rape in 25 is reported.
"Rape is completely trivialized by a great number of men. It is seen as a legitimate activity," said Rachel Jewkes, a lead researcher on both studies.
Out of the 511 women surveyed, more than 51% said they'd experienced violence from men, while 78% of men said they have committed violence against women.
Jewkes also said that apartheid in South Africa has contributed to these stark rape statistics, noting that it destroyed family life, in addition to fostering violence and anti-social behavior.
