compiles the causes of childhood accidental deaths. Of the major causes, death by firearm has fallen the fastest and furthest since the mid-1990s; so much so that children are less likely to be killed by gun accidents than by falls and drowning.
The vast majority of gun-owners are quite responsible, since during this same time the number of firearms in U.S. civilian hands has gone from 190,000,000 to around 320,000,000. I wish adults were as effective in taking measures to prevent falls and drowning.
