—The presence of one or more guns in the home has been associated with a 1.6-fold (95% confidence interval [CI], 1.2 to 2.2) increased risk of homicide1 and a 3.2-fold (95% CI, 2.4 to 4.4) increased risk of suicide.2 We investigated how many deaths in the United States might be attributable to guns in the home for the period 1988 through 1990.Using medical examiner, vital statistics, and survey3 data, we estimated that 46.7% (31092) of the 66578 homicides and 66.4% (60 786) of the 91 545 suicides during these 3 years occurred in the home and that 43.2% of homes had guns (95% CI, 41.4% to 45.0%).We used an attributable risk approach and the point estimates and lower and higher values of the CIs for the prevalence of guns in the home3 and the unadjusted gun-related risks of homicide and suicide
