Injuries may be divided into three broad groups – preventable (accidental), intentional, and undetermined intent. Most of Injury Facts presents data on preventable injuries, which account for about 70% of all injury deaths in the United States. This section investigates intentional injury trends and how they compare to preventable injuries.
Intentional injuries may be divided into four subgroups – intentional self-harm (suicide), assault (homicide), legal intervention, and operations of war.
Intentional self-harm includes suicide and attempted suicide resulting from purposely self-inflicted poisoning or injury. The most common methods of suicide are firearms, hanging, strangulation and suffocation, and poisoning. Suicide accounted for 47,511 deaths, or 19% of all injury-related deaths in 2019.
