I did [1], 2015-2016 saw 51895 reported "crimes of sexual nature". There seems to be a giant amount of unreported rapes though: While women's groups in South Africa estimate that a woman is raped every 26 seconds, the South African police estimates that a woman is raped every 36 seconds and In 1998, one in three of the 4,000 women questioned in Johannesburg had been raped, according to Community Information, Empowerment and Transparency (CIET) Africa and It is estimated that over 40% of South African women will be raped in their lifetime and that only 1 in 9 rapes are reported. draw a drastic image.
Looking at US stats the homicide rate is 0.007% and sexual assault 0.1% per year.
