Soccer records participation very differently to AFL (and NRL I think).
Soccer basically includes anyone who attended a promotional event or anything soccer related as a participant.
AFL and NRL only count those who are registered with a club or training program as participants.
In terms of actual registered players with a club or junior program the soccer numbers are far less than you think.
Soccer also has a lot of double accounting that significantly boosts numbers.
The number of participants in the teenage years is much more important than the total number of participants.
Auskick is important to the AFL as it leads into the teenage years with a pathway.
Junior numbers are not important to some sports like cricket that seem to start only in the teenage years.
Large junior numbers for baseball and soccer don't provide the throughput for professionalism.
