"I didn't even attempt it," he told LiveScience. Griffith conducted his study on pornography without the benefit of outside money. Add to that short career spans, a reluctance to be put under the microscope and a population of performers centered in Los Angeles County, where many researchers don't have the luxury of spending time, and it's a recipe for lack of research.Īnother barrier is funding. Part of the reason is that there just aren't that many porn stars - about a thousand working at any given time, Kross said. Meanwhile, academic research on the porn star population is lacking. "It's just that those stars have never been as big as the blonde stars." "There have been more brunette stars than blonde stars," she said. (Millward plans to make his methods available on his website.) Kross, however, said the results didn't surprise her. Millward's data is not published in a research journal or peer-reviewed by experts, so scientists like Griffith take it with a grain of salt. Nikki is the most common name for female porn stars, Millward found, and David is the most common name for men. About 39 percent have brown hair, 22.5 percent have black hair, and only about 5 percent are redheads. Only 32.7 percent of porn actresses have blonde hair, whether natural or dyed. Nor are blondes as dominant as might be expected. 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.
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. 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.
In fact, the most common bra size among porn stars is a 34B, compared with 36C for the average American woman. The stereotypical porn actress - with enormous breasts and blonde hair - doesn't match reality, Millward found. Stereotypes were the motivation for Millward, whose analysis of porn stars includes a facial composite of the "average" actress. Ultimately, the findings could lead to better understanding of sexual health, sexual identity and other aspects of the high-grossing porn business. Though it's hard to know for sure without more extensive studies, early explorations have found these stereotypes fail to hold up. This lack of research is notable given the number of stereotypes about porn actresses, particularly that they have high rates of childhood sexual abuse and psychological problems.
