When people generally think of female porn stars, they tend to think of blonde hair like Kayden Kross up there, or they think of gigantic, cartoonish fake breasts and loads of makeup and plastic surgery. And while that may be true for some of the older actresses from your creepy uncle’s generation, today’s porn actresses have built an all new mold of their own. So much, in fact, that one man’s study of porn star demographics has revealed something quite shocking about the average adult film starlet.

The average adult film actress is a brunette with a B-cup named Nikki, at least according to blogger Jon Millward, who spent six months analyzing the demographics of 10,000 porn stars drawn from the Internet Adult Film Database. But what’s known about porn stars beyond their breast size? Remarkably little, thanks to practically zero research funding and a community wary of researchers.

“The average span of a performer’s career is usually only about six to 18 months, so the benefit of participating in these things isn’t usually apparent to the people who are in it at the time,” Kayden Kross, an adult film actress and writer, told LiveScience. (Via Mother Nature Network)

That’s an incredible revelation. Porn actresses are basically the running backs of adult films. So what else goes into this kind of “porn demographics” analysis? The results may blow you… … … r mind. Had you fooled there for a second.

The stereotypical porn actress — with enormous breasts and blonde hair — doesn’t match reality, Millward found. In fact, the most common bra size among porn stars is a 34B, compared with 36C for the average American woman. High obesity rates among the public may explain some of the discrepancy in breast size; porn actresses are also thinner than the average American woman. According to the numbers given on Internet Adult Film Database profiles, the average female porn star weighs 117 pounds (53 kilograms), which is 48 pounds (22 kg) less than the average American woman.

The average male porn star weighs 167.5 pounds (76 kg), 27 pounds (12 kg) less than the national average of 195.7 pounds (89 kg) for men.

Nor are blondes as dominant as might be expected. Only 32.7 percent of porn actresses have blonde hair, whether natural or dyed. About 39 percent have brown hair, 22.5 percent have black hair, and only about 5 percent are redheads.

That means that an actress like Faye Reagan is practically a unicorn. Wait, I mean, who is Faye Reagan? What’s this about again? What’s porn? Why aren’t I in church right now? Stop judging me, heathens.
