Jon Millward deosn’t watch porn like the average man: instead, he sees it as a heaving data set to analyse and graph. No, really. That’s why he’s visualised porn star demographics to work out what the typical, ahem, actress look like.

Having scraped the Internet Adult Film Database for physical attributes—hair colour, race, sizes, and so on—he set to work analysing the data. (It’s worth noting that his website doesn’t contain any NSFW images, but there may be some terminology there that could raise your boss’ eyebrew.) Millward explains his findings:

[T]he most common bra size for a female porn star is a surprisingly handleable 34B. Not double-D, not even a D. Double-D actually came in 4th, behind B, C and D. The most common set of measurements for the women was 34–24-34.

So, if the average female porn star is a 5’5″ woman who weighs 117lbs and has B-cup breasts, what color is her hair? Blonde, presumably, if my friends’ guesses were anything to go by.

Apparently not. Dark-haired porn stars outnumber blonde ones almost 2-to-1.

Sadly, there’s no temporal data—he doesn’t look at how those figures have changed, quite literally, with time—but if WIRED’s Playboy playmate BMI analysis was anything to go by, you can be sure they haven’t remained constant. [Jon Millward via Flowing Data]
