Gun Ownership Rates

Buried in this post about the correlation between guns and crime is an amazing statistic. Evidently, in 1993, 45% of Americans said they owned a gun. In 2009, 33% of Americans said the same thing.

If this is true, it's quite remarkable. That's a sea change decline in gun ownership. I don't know much about this issue so I have no sense of why that would have happened (certainly I wouldn't have predicted it). Are young people more adverse to guns? That's the best reason I can think of. But it may well not be the case.
