That seems to track. The top countries are the places with the desire and the wealth to maintain a population of pro dommes. One simply cannot have a dedicated playspace and the investment in the craft where people cannot spend more than 200 an hour for a session.

A consideration is traveling dominas. While I was in Barcelona I was once a month, touring the Middle East. Because of different standards and marketing I had a whole separate website and social media for my tours there. Then you would have counted me twice, once for Spain and once for the UAE. Almost no one is based in the UAE--I can think of 2. The elevated tribute rates do attract a lot of touring dommes.

Actually there are a lot of things that would consider with who is a pro-domme. I think that this would take a MASSIVE amount of effort and you would probably come up with similar results.
