I ran across an old post on the Freakonomics blog that talks about how NHL players tend to have their birthdays during the first three months of the year. A Canadian hockey commentator comments (…heh) on the post:
Most elite hockey players from North America are born in the first three months of the year. In fact, approximately 3/4 of the players in the Hockey Hall of Fame were born in January, February or March.But it’s an entirely different case among elite level European players, especially those from the old Eastern Bloc. Why? Because unlike North America, hockey programs in those nations are part of the school system, and thus use the school calendar as their basis. When looking at the highest scoring European players, we find mostly September, October and November birthdates.
I thought it was interesting.
