Do you know of any studies or reviews that try to characterize what demographics are more or less attracted to polyamory, or more or less likely to practice it?

Related, but different: Most people who are or would be poly likely wouldn't know it or do it if they're not exposed to the idea, and even more so, if they don't see it modeled in their society - and I think are more likely if they see it modeled in their social group. So if you take a population somewhere that has had little exposure to polyamory or are unaware of it, and mix them into a group where polyamory is commonplace, some of the people from the original group will themselves be poly, and it will be right for them, even though they may not have thought of it or seriously considered it before. But of course many people in the original group would stick with monogamy.

Are there any studies that try to find what factors make someone more or less likely to be open to polyamory or have that tendency, even if it's not expressed? Related to the demographics of polyamory I asked about in the first paragraph, it may be that some groups of people have less predilection for polyamory, but other groups may have a lower proportion of poly people mostly because it's less common in those groups and people don't see it around them as much.

So, that's really what I'm looking for: Any studies that explore those ideas and have figured out ways to get real world data about them?
