This is a great collection of data from 2008 giving survey data from many many thousands of US citizens, broken up by age, sex, and other demographics. I've been going through it today trying to see if the numbers help support the red pill models many of us believe in response to the 'Is the Cock Carousel Real?' post I first saw today. Topics such as the 80/20 rule and hypergamy.

Using the information about number of sexual partners, I was trying my best to figure out how to map the numbers are close as possible to reasonably approximate polynomials. This has proven difficult so far. All of the approximations I find are just wildly all over the place. If someone more statiscally savy than I has ideas on how to plot the data well, I'd love to see it.

While I don't think it can help prove the existence of hypergamy, I do think it paints a clear picture of the 80/20 rule (20% of the men are having 80% of the sex) in effect, but it's not actual 80/20. Pages 19 and 20 of the report show the percentage breakdown by age category, education category, marriage/cohabitation category, and race category. Two very important and consistent traits can be seen: the number of men in the 0 sexual partners range is significantly higher than the same in the females, and the number of men in the two higher partner count categories is significantly higher than the same in the females, and the median numbers for men are significantly higher than the females. In short, the higher value sexual active men have more sexual partners than the equivalent higher value, sexually active women, while the lower value men have less sexual partners than the equivalent lower value women. I have no idea how to derive the actual numbers that should be used in place of the 80/20 rule, but the disproportion appears obvious.

I believe there is a ton of useful data in this report, and wanted to make sure people were aware of it. There are some real gems in this.
