Since the White House has been bitterly complaining about the conservatives/NRA/et al, blocking the accumulation of any gun statistics other than commercial sales totals, I'd take these stats with a grain of salt.

The move away from hunting by the younger crowd isn't surprising, many can't be bothered to even get a drivers licence... wussies.
The increasing density of the burbs, would discourage many guns that were formerly bought for plinking or shooting sports. Towns like mine have instituted no discharge of firearms(outdoors) ordinances, although the 3200 member gun club, a few hundred yards from my house, is busy.

One thing I have noticed is less comment by owners about their own collections, in groups other than close friends who already know. It's become a polarizing subject like abortion.

I'd suspect the supposed drop in Wyoming can be attributed to a large population of survivalists that don't tell nobody nothin' nohow, about their preparations for the apocalypse.

I think first and foremost we need more data, which Obama has attempted to institute. Both sides(see, polarizing) are using outdated, incomplete, and downright wrong information to back their arguments. Even neutral, impartial parties, simply don't have enough valid, and current data.

Of course even with good data the emotional content will still be strong, and I think a majority imposing their will on a minority, which the constitution was supposed to prevent, will always be as bad an idea as the other way round.
