1. Almost half of gun owners own four or more guns
We analyzed a nationally representative household telephone survey of over 2,750 adults conducted in 2004. We found that 38% of households (45% of men and 11% of women) reported owning at least one firearm. Almost half (48%) of gun owners report owning four or more guns with a few possessing large numbers of guns; 64% of gun owners own at least one handgun. Gun ownership remains widespread, but a smaller percentage of gun owners possess an increasing percentage of the gun stock.

2. Owners of semi-automatic guns are more likely to binge drink than other gun owners
We analyzed data from a national random-digit-dial telephone survey. Owners of semi-automatic weapons are more likely than other gun owners to be male, own a gun for protection, and report binge drinking.

3-4. Gun ownership creates external psychic costs
We analyzed whether perceptions of safety might be affected if more people in a community acquired firearms using data from a national random-digit-dial survey of adults conducted under the auspices of the Harvard Injury Control Research Center. By a margin of more than 3 to 1, Americans would feel less safe, not safer, as others in their community acquire guns. Among women, but not among men, those who have been threatened with a gun are particularly likely to feel less safe.
