I would say that outdoorsmen are a subset of the typical angler. I do not see the number of angler decreasing as I would say outdoorsmen. I also would not lump hunting and fishing into one group. They are distinctly different activities, though with a good deal of crossover. I don't hunt anymore, probably never will again. It's just not interesting to me, as fishing is these days. Based on the the number of advances made, the cost of much of the gear, and the shear level of online marketing done, I'd say there is growth in fishing. Seems like more and more companies fighting for a market share, and for higher and higher price points. The average guy that bass fishes with any seriousness has as much tied up in their hobby as many golfers. I've watched this shift for the past two decades. A 20' bass boat costs as much as membership to a private golf club, these days.
