Not a peer reviewed study, but here is the new york times article that it is from: https://www.nytimes.com/interactive/2017/09/29/sunday-review/100000005462919.embedded.html
And here is a link to the book that was referenced for the data: https://www.amazon.co.uk/Dataclysm-When-Think-Ones-Looking/dp/0008101000
Is that good enough, or does every piece of information on the internet have to be peer reviewed for it to be acknowledged?
Dataclysm is an interesting read in case you haven't read it. Written by the creator of OKCupid.
For those who enjoy the OKCupid style data check out their co founders book 'Dataclysm', I am currently on the last chapter and have loved it, great book on data.
