No Guns

Child and Teen Firearm Mortality in the U.S. and Peer Countries The United States has by far the highest rate of child and teen firearm mortality among peer nations. In no other similarly large, wealthy country are firearms in the top four causes of death for children and teens, let alone the number one cause. U.S. states with the most gun laws have lower rates of child and teen firearm deaths than states with few gun laws. But, even states with the lowest child and teen firearm deaths have rates much higher than what peer countries experience.
