Gun deaths among American school-age children are increasing sharply. A new study out of Florida Atlantic University found that in 2017, more kids between the ages of five and 18 were killed by guns than police officers or active duty members of the military. In that year alone, guns killed more than 2,460 children. Going back to 1999, there were almost 39,000 gun deaths among children, including 6,500 between five and 14. The majority of the deaths, 61%, were the result of assault. About a third were suicides. There were noticeable trends along race and gender lines. More than 40% of the deaths were black children and 86% were boys. The data was published this month in the American Journal of Medicine.
