I've heard that lifetime incidence of being raped for women is about 3% worldwide.

That's much lower than the estimates I usually see. E.g., the Wikipedia article Estimates of sexual violence quotes a self-reported rate of 14.8% lifetime incidence among U.S. women, not counting failed rape attempts. This refers to this study[1], which quotes two previous studies with similar results, and also estimates a 22% lifetime incidence rate under a broader definition of sexual assault.

There are whole countries out there where the rape incidence in any single year is far above 3%. Even putting "unstable" countries and temporary situations (those lasting one generation or less) aside, there are many societies where the structure of marriage is such that we ought to estimate a daily incidence of rape, perhaps far above 50%.

I wonder where I read 3% (it was very recent) - unfortunately all I can see now are order-of-magnitude higher estimates for what i presume is the broader category of "sexual assault".

You're right.

I found my "source" - it was a blog comment

the UN gives an annual incidence for rape per 100,000 people. If we assume rapes of men or of women outside ages 15-50 are (fairly) negligible, then the victim pool is only about a third of the total pop, if that – giving a rate of 0.03% * 3 = 0.09% for the victim pool. Since women are in the pool for 35 years, that gives a lifetime prevalence of about 3.15% (leaving out the correction for a few individuals being victimized more than once). 3% is high.

I've seen 4-10% elsewhere.

That comment uses the figure quoted by the previous comment. But look at the pdf linked there for the UN report - that's not a number of rapes, that's a number of "crimes recorded in criminal police statistics!" No wonder it's much lower than the real figure. (I don't even know if it includes all reports/accusations or just counts found guilty by a court.)

Incidentally that document is missing some of the more interesting statistics for the US, while it has them for other countries. "Rape average prison sentence served" is one.
