I can't tell you how many people play snooker and darts worldwide. I would suspect that more people watch it on TV than play it. According to World Snooker, 361 million people watched at least 5 minutes of the 2011 World Snooker Championship. 361,000 people didn't watch the World Chess Championship on YouTube. The Candidates on Livestream didn't appear to reach 3,610.

How does this compare with darts and snooker? Or you could reflect the longer active lifetimes of chess players by using active > 2500 as the proxy.
That's very arbitrary. Snooker and darts don't really have the concept of a GM or an IM at all. I can count people who make a living with just prize money. I've defined that as people who earn £20,000/year in prize money, not including appearance fees, sponsorship, or any other commercial activity. That makes 39 for darts (PDC) and 57 for snooker. How many of the top chessplayers earn £20,000 in prize money per year? I don't know how this would compare with chess, but Luke McShane is ranked 60 (December 2013), and he's not a professional player. I suspect the £20,000 criterion isn't very far away from the 39-57 range.
