Maybe league participation has gone down for youth bowling. I don't have any concrete data one way or the other. But it has been harped on and on how the sport of bowling has a bunch of old fogies who will be leaving the sport and then it will die. Less youth league bowlers means less future league bowlers....
But when I was young, most of the youth I bowled with didn't really care about the actual competition. They were interested in other sports also and those usually won out in the end. What I care about for the future of the sport of bowling is the number of youth who want to bowl competitively. Youth who want to continue and bowl in adult leagues. We do have some numbers that show those numbers increasing, and by a lot.
In 2011, Junior Gold had 1,647 participants. In 2015, there were 3,190 participants for a 94% increase in Junior Gold participation. I like the sound of that.
In 2009, the Youth Open Championships had 3,493 separate entries in Team, Doubles, Singles and All Events. Obviously there weren't 3,493 bowlers, but the number of entries is quite high. In 2015, there were 6,653 separate entries in Team, Doubles, Singles and All Events for a 90% increase in participation. Again, that is pretty good. And even better, there were twice as many participating as a scratch entry as compared to handicap.
The youth bowler of today wants to compete at the highest level. The youth bowler of today wants to compete on conditions tougher than the typical adult bowler. The youth bowler of today is the future of the sport of bowling.
