We've known for the last 20 years the number of hunters has been in decline. This is very old news. I think a lot of it is due to the unfettered access to our children that the anti-gun and anti-hunting forces are allowed in public schools, and the active opposition to allowing pro-gun or pro-hunting views being made available to them. Young people are being taught hunting is wrong and older hunters are... well, doing what we all do, eventually. They're not around any more.
