The #1 cause of death among American children

Not cancer or any disease presented in public service announcements...

"The previous analysis, which examined data through 2016, showed that firearm-related injuries were second only to motor vehicle crashes (both traffic-related and nontraffic-related) as the leading cause of death among children and adolescents, defined as persons 1 to 19 years of age. Since 2016, that gap has narrowed, and in 2020, firearm-related injuries became the leading cause of death in that age group. From 2019 to 2020, the relative increase in the rate of firearm-related deaths of all types (suicide, homicide, unintentional, and undetermined) among children and adolescents was 29.5% — more than twice as high as the relative increase in the general population. The increase was seen across most demographic characteristics and types of firearm-related death."

Several of the countries in that list have compulsory military service, which results in weapons being kept at home.
