Risk of Suicide Mortality among 1 Million Handgun Purchasers: A Cohort Study

The rate of suicides in households that have a firearm is higher than non-gun owning households. This is not a matter of differences in mental health or other known factors. To better understand this, comparing one million gun owners with nineteen million who do not own guns and analyses with linked data from voting and death records may shed some light. Lessons for community interventions and prevention strategies will be identified.
