"Rape statistics by country
This table indicates the number of, and per capita cases of recorded rape by country. It does not, and indeed cannot, include cases of rape which go unreported or unrecorded.[142][306] It does not specify whether recorded means reported, brought to trial, or convicted. Each entry is based on that country's definition of rape, which varies widely throughout the world. The list does not include the estimated rape stats of the countries, per year, such as South Africa having 500,000 rapes per year,[307] China having 31,833 rapes a year,[308] Egypt having more than 200,000 rapes a year,[309] and the United Kingdom at 85,000 rapes a year.[259]"
Just a cursory look through the stats of per capita rape in 2010, (the last year shown), of the countries where there are ANY statistic quoted, shows that:
The following countries show a higher rate than the US:
Botswanna
Grenada
St Kitts
Nicoragua
Panama
Sweden
Belguim
Australia
South Africa.
Of the 110 countries listed, 63 did not have ANY stats for that final year, and (as noted in the WIki page, countries have VERY different ways of finding those stats, including in the middle east and africa, where female children of 12 or 13 (or even 9 and 10), being married off to middle aged men is NOT considered rape, even when it is against their "consent". (Not that I think that a child is capable of "consenting" to sex).
I'm not sure that you are reading your own sources very carefully when you keep on quoting the US as #4...
