Let's have some more fun with math. For some reason I can't seem to find any estimates on the percentage of men that commit sexual assault. LOT's of stats about their victims, but, so far, I can't seem to find anything that says X% of men commit Y.
I have been able to find percentages on college males, however, so
those will suffice:
A 1987 national survey found that among college men, 4% reported they had committed completed rape, 3% attempted rape, 7% sexual coercion, and 10% unwanted sexual contact since age 14 years (Koss, Gidycz, & Wisniewski, 1987). Similar rates have been found in more recent studies, with 11-14% of male students reporting some form of SA over the preceding year (Abbey & McAuslan, 2004; Monson & Langhinrichsen-Rohling, 2002; Thompson, Kingree, Koss, Goree, & Rice, 2011; White & Smith, 2004).
Because self-reporting of criminal behavior is notoriously low, we can comfortably take the 24% total from the 1987 survey and add another 10% at the very least for a general estimate as to how many men commit varying degrees of severity of sexual assault--ranging from "unwanted sexual contact" to penetrative rape--at 34%.
There are around 150,000,0000 men in the US, so, using the college numbers as an indicator, that's about 51,000,000 who are full-on
active predators; i.e., those who have
already committed some form of sexual assault since the age of 14.
Further, we have
this to consider:
Only two studies of college men had large enough samples to investigate what percentage of rapists are repeat rapists, one a study of typical 18-22 year old men at large university and the other of older men at a commuter school. Both studies found that two-thirds or more of college rapists are repeat rapists who have raped four or more times on average, even within a single year of college.
Due to simple math, those two-thirds of college rapists who average four or more rapes each account for the vast majority of college rapes, around 90% or more. A study of college-aged Navy recruits had the same findings, which suggests that these statistics are not determined by whether men are college students or not. Finally, in the study of typical college men about 25% of rapists, the majority of whom are repeat offenders, admitted to raping in more than one year of college. However, that 25% statistic depends on rapists, including repeat rapists, being equally honest, year after year, on survey questions about rape.
From this we have the fact that a certain large percentage--two-thirds--of college rapists rape
four or more times per year. Now, some may argue that college affords more opportunities for predators, but that's irrelevant to
intent.
So, two-thirds of the 51M that commit some form of assault is about 34 Million men in America that would commit at least four or more
rapes (full-on penetrative) per year, so it's safe to assume the number of "lesser" assaults would be much much higher for those other 17 million, so let's say it's on the order of five times more? Per year.
Again, at least in regard to intent, if not execution. Iow, if the circumstances present themselves, 2/3's of active predator males would rape four or more times, while 1/3 would sexually assault (in a "lesser" severity sense) twenty or more times. Per year.
So, again, conservatively, 34 M times 4 would be 136 M full-on rapes per year; 17 M times 20 would be 340 M "lesser" severe assaults per year for a grand total of some 476 Million sexual assaults--potentially, as a condition of very general estimates on the lowest end of the scale and in the sense of the "pool" of possible incidents just as a factor of
active predators and their intent--per year.
Now throw into that pool a woman like Carroll, who swims in the higher risk end of that pool (i.e., she is a celebrity who worked and lived primarily in large cities with higher percentages of such predators and interviewed/mingled with people in positions of power and industries that would attract such predators, etc).
Iow, swimming in the deep end of the 476 million yearly potential sexual assaults pool for seventy five years, only having a list of 21 "hideous men" (i.e., predators that she met along that way) is nothing.
