Over at Polytical, there is a summary and discussion of a recent small, anonymous, survey of polyamorous people which may be interesting to people who are interested in such things.
UK Poly Mailing List Demographic Survey Results
I was interested to see that the largest segment of them were atheist/agnostic/humanist. Granted, it is the UK and not The US, but I like to see poly people who are also atheist/agnostic/humanist.
The overwhelming majority of people were white; 92%. This seems about on par with, if not slightly above, the demographics of the UK in general (at least from the census from 2001, which may be out of date). I would be interested to see the comparative demographics of polyamorous people in the US compared to the general population. My guess is that the percentage of white people in the poly community would be higher than the general population. That because while I don’t think polyamory is privileged, it is definitely easier to be polyamorous when you have privilege.
And, unfortunately, privilege and race often co-mingle. It’s part of why I care about social justice, and thus support the whole atheism+ thing.
In any case, take a look at the survey results if you like, and let me know if you see more similar surveys in other parts of the world.
