The bar chart shows the causes of injury that result in traumatic brain injury (TBI)-related deaths vary by age group.

In 2013, 77% of the TBI-related deaths among infants aged <1 year were from causes other than transportation, firearms, or falls, and primarily resulted from assault and maltreatment.

Transportation accounted for 53% of the TBI-related deaths among children aged 1-14 years. Firearm-related injuries accounted for 50% and 52% of the TBI-related deaths for persons aged 15-24 and 25-64 years, respectively. Most of the firearm-related TBI deaths in these two age groups were suicides (62% and 83%, respectively). The majority (61%) of TBI-related deaths for those aged ≥65 years resulted from falls.
