The source talks about people getting into rugby and registering. It would seem these numbers include anyone in any kind of registered league, professional or otherwise. This makes sense of the numbers a little, for example 0.5% of Americans you meet are not professional rugby players.
Professional rugby is popular in Argentina, that's the problem with these stats. The numbers would mostly be school grade sports. That's why USA has 1.5 million rugby players, and almost no International recognition.
You could also compare USA and Brazil for football. According to FIFA the US has a higher per capita player rate.
Both Argentina and Italy appear in the Top 20 when it comes to total numbers, but given their huge population figures, they (only) get a per-capita amount of 3.08 per 1000 (Argentina) or 1.46 (Italy) respectively.
I know JetPunk doesn't accept the individual parts of the United Kingdom as countries in their own right, but for the purposes of this quiz, it would interesting to see the numbers for Wales, England and Scotland separately. Especially since they have separate teams in international rugby. They never play as the United Kingdom.
I really, really doubt that 582/1,000 (58.2%) of Tongans play rugby, even with semi-pro. In fact, I think all of these numbers should be out of 10,000, since when I checked about 6,891 out of 103,197 (or 668/10,000) Tongans are in the Tongan Rugby Union. Just saying.

I thought there are only rich people. They play Golf, Tennis, and that stuff but rugby? Kinda weird
