I believe you mentioned earlier that the figures do not take into account non-reporting.

Intra-family sexual abuse of children, a majority of whom are girls, has an extremely low reporting rate.

There is no evidence that such abuse is less common in high-income households than in low-income households; there is evidence to the contrary in fact, that socioeconomic status is not a relevant factor. The same is true for spousal sexual assault, obviously a severely under-reported offence.

On the other hand, socioeconomic status does have an influence on mobiity. As I pointed out, a large proportion of the high-income households in Brookline will not consist of people born and bred locally. They will probably have been born elsewhere and attended postsecondary institutions in a different place again, for example, settling in Brookline because of the employment opportunities, and women in university are at relatively high risk of "date rape", for example.

So the data as you presented them simply fail to take into account a lot of things that are directly relevant here.

I don't know why you are "assuming" that 20% of women in the US have been sexually victimized. That assumption is completely out of line with any estimates based on actual research.

In my own immediate circle, I was a victim of a "classic" stranger rape: abducted, choked into submission, escaped with my life but just by the skin of my wits. My best friend was a victim of date rape in university. My nephew's mother was abused by her father. I could go on. I'd be hard pressed to name a friend who has not been the victim of sexual assault -- and, like the Canadian Criminal Code, I don't distinguish between vaginally penetrative assault and other sexual assault. All forms of sexual assault can be equally traumatizing for the victim, all of them have chilling effects on women's presence and participation in all spheres of our society.
