I dont think you can use hunting licensed sales to gauge the number of traditional archers vs compound archers. A very small number of the total numbers of all archers hunt. More than half of the members of both the archery clubs I belong to hunt. One club is trad only, one is open. I shoot trad only in both. Three other members of my household that shoot but dont hunt, and there numbers still figure in the equation. My son shoots in the JOAD group and they are non hunters (for now). Not to mention the scout groups that shoot regularly. Also, we have a local home school group that numbers in the 60's, plus the archery in schools programs. Fita groups, flight shooting, indoor 3-d, lots and lots of clubs that have absolutely nothing to do with hunting.
All that said, I hunt, I shoot alot to be a better game shot. I know I'm in a nation wide dwindling population and it sucks to know, considering how much I love the outdoors and archery.
