Mental Health Gun Violence Statistics

Gun violence and mental health are intertwined, yet 79.6% of US gun deaths are suicides, highlighting why safe storage and crisis support matter as much as policy and enforcement. This page brings you up to date with how widely 988 is used and how effective interventions like safety planning can be, alongside stark cost and burden estimates from individual households to the global economy.

Firearm injury and suicide data can look like separate stories until you line them up. Even with mental health hotline use reported by 13% of U.S. adults in 2022, 79.6% of gun deaths were suicides in 2022, and that split drives very different prevention needs than most people expect. This post brings together the statistics behind firearm deaths, risk screening, crisis response, safety planning, and access patterns so you can see where mental health and gun violence intersect.
