This data is sourced from the "big kink survey" (more results here). You may think: "how on earth is this pervert survey representative?"

Obviously no online sex survey is truly nationally representative of any country, but the overwhelming majority of respondents were White Westerners.

Respondents came from a variety of sources (twitter, tiktok, reddit, etc.) and the sample is weighted to make it more representative of the US population.

It also has a colossal sample size of n=980,000, which you can heavily filter to explore results from specific subpopulations, excluding certain sample sources, races, and so on.

Respondents were mostly left-wing, hence the "very liberal white women" sample size being ten times larger than the "very conservative" sample size, but this doesn't really matter when there are still thousands and thousands of non-leftist samples.
