I found a much cheaper survey on participation on the sports for US140 dollars.

you can click on the sample to find out the number of participants.
Waste of time. These are cross-participants whose main sport is baseball. Also, the numbers are rubbish, and the reason would be immediately obvious to people who actually do the sport.
