It appears RHDs don't exist anywhere on this planet.
I actually wonder how many Crazy Hockey Dads are giving their kids right-handed sticks when they first start to play for this reason.
On a whole, there's not many right handed players any more. Probably 2 or 3 to 1, Lefties to Righties on any team I've every coached. Out of 15 skaters this past season I had 2. Both forwards. The year before I had 3. All defence.
I've heard it said that the earlier a kid starts the more likely they are to be left handed. It has something to do with younger kids preferring their dominant hand at the top and older kids naturally putting it mid stick, and most people are right hand dominant.
The study was done to understand why traditionally Canada produces more lefties and the rest of the world always had more righties. That's changing now though, even in Canada kids are starting earlier than they used to. Most people I know started their kids at 3 years old. Mine started at 4 and even that seemed earlier than necessary. I started at 5 when I was little, but there's real pressure to get them going as soon as they can.
