  • Values in parentheses are standard errors estimated using the Taylor series linearisation method to account for the stratified, clustered sampling design; weights were applied to all prevalence estimates to adjust for differential probabilities of selection, non-response and differences between the sample and 2000 US census population estimates.

  • *Difference between firearm and non-firearm households within sex is significant at p<0.05 using the Rao–Scott χ2 test of proportions.
