It’s no secret that I’m a data nerd.  I also enjoy roller derby. Recently I was asked the question…  How many roller derby leagues are there?  Well, I couldn’t give a definitive answer because the most often quoted resource for this sort of info hadn’t been updated in months.

So I set out to update it the best I could.  The resulting comprehensive list of roller derby league can be found here.  Granted, with a sport that is growing as fast as roller derby it’s impossible to stay ahead of it all, but I do my best.
