The “other” category is defined as any firearm death that is not defined by the CDC as a homicide or a suicide. This could include unintentional, undetermined, and legal intervention.

Fewer than 20 firearm suicides were reported during this time period for the following races and Hispanic Origin category and therefore are omitted from the above chart: American Indian/ Alaska Native females and males, Asian/ Pacific Islander females and males, and Hispanic/Latina females.


  • The most recently available CDC data is 2018; as such, 2018 data is used where appropriate.
  • Unless otherwise specified, statistics reflect 5-year averages (2014-2018).
  • All rates listed are age-adjusted in order to allow for accurate comparisons between populations with differing age distributions.
