There have been 1,516,863 gun-related deaths since 1968, compared to 1,396,733 cumulative war deaths since the American Revolution. That’s 120,130 more gun deaths than war deaths -- about 9 percent more, or nearly four typical years worth of gun deaths. And that’s using the most generous scholarly estimate of Civil War deaths, the biggest component of American war deaths.It's suicide by gun that accounts for most of these deaths:
In fact, homicides represent a minority of gun deaths, with suicides comprising the biggest share. In 2013, according to CDC data, 63 percent of gun-related deaths were from suicides, 33 percent were from homicides, and roughly 1 percent each were from accidents, legal interventions and undetermined causes.
