Trends in Firearm Mortality, Suicide, and Homicide and Demographic Breakdown of Firearm Mortality in 2018

All rates, with the exception of age-specific rates, are age-standardized with regard to the 2000 Census. Total firearm mortality includes all intents or manners of firearm death: homicide, including legal intervention homicide (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10]: X93-X95, Y35.0, U01.4), suicide (ICD-10: X72-X74), unintentional (ICD-10: Y22-Y24), and undetermined intent (ICD-10: W32-W34). The urbanicity categorization is based on a condensed version of the 2013 National Center for Health Statistics (NCHS) county urban-rural categorization (https://www.cdc.gov/nchs/data/series/sr_02/sr02_166.pdf). We used the same 4-group categorization used in prior data briefs (https://www.cdc.gov/nchs/products/databriefs/db151.htm) and adopted the labels urban (NCHS: large central metro), large suburban (NCHS: large fringe metro; described as a large suburban area in data briefs), smaller suburban (NCHS: medium metro and small metro), and most rural (NCHS: micropolitan and noncore).
