Overall, in the eight years following Sandy Hook (official data on gun violence is only available through 2020), more than 25,000 children died from gun injuries. Most lost their lives to assault (64%), about a third to suicide (30%), and the rest to negligence, such as poorly stored guns in their homes.


Firearms kill so many American children that they are now the leading cause of mortality under age 19, ending the lives of 5.3 kids in every 100,000 and surpassing even motor vehicle deaths, which are 4.8 per 100,000.

Not only can no other peer nation claim guns as its top cause of child deaths, but firearms mortality rates for children are dramatically lower in other high-income countries, which all have much stricter gun control laws than the US. In Canada, which ranks second, the rate is 0.8 per 100,000; in France, it’s 0.5. On average, in comparable countries, it’s 0.3 per 100,000.
