The number of fatal firearm accidents, or unintentional firearm fatalities, have been falling for more than 50 years. At the same time, the number of firearms in the United States has been steadily rising. The cause of fatal firearm accidents is not correlated to the number of firearms in society . . .
The red line is the number of private firearms in the United States, in units of 100,000. At the end of 2013, the estimate was 363.3 million. The green line is the number of fatal firearm accidents, or unintentional firearm fatalities, in the United States. The number in 2013 was the lowest recorded, 505. The absolute numbers are important, but the rate of unintended firearm fatalities per 100,000 population is a better measure of safety.
