[W]hether you’re the firearm owner yourself or anybody who lives in the home [where] there’s a firearm present, their risk for death by suicide goes up three to five times.
And it’s not that the firearm makes them vulnerable to thinking about suicide. It’s just that if someone is thinking about suicide and they have quick and ready access to the most lethal method, then they’re at greater risk of dying. If you take all the other suicide attempts together in the United States to combine them, less than 5% of those attempts to result in death. There’s nothing that compares to firearms in terms of how deadly they are in a suicide attempt.
