> reasons to think the CDC undercounts DGUs, most notably that they only asked people who had a gun in the home if they had used a gun in self-defense.
Can you point me to something to back-up this claim? My gun-enthusiast friends often accuse the NCVS of under-counting, usually having to do with survey methodology flaws. But I've looked at the survey[1], and I can't find anything so substantiate their (or your) claim.
But, even still, the CDC numbers are _orders of magnitude_ lower than Kleck et al.--like 10x lower (afaik-not an expert here). So it's a tough pill to swallow that minor (or even substantial) survey errors would lead to that sort of discrepency.
