• Fatal and nonfatal injury data use different coding rules for injury intent and mechanism. Compare estimates across these data sources with caution.
• The percentage displayed for each of the top 5 causes of injury death is calculated using the number of deaths due to each intent/mechanism combination in the selected age group divided by the total number of injury deaths in the selected age group. Injury deaths among infants aged <1 year and among persons of unknown age are not included in leading cause of death calculations when "All Ages" is selected.
• Age-adjusted rates are displayed for “All Ages” data. These rates are calculated using the direct method and the 2000 U.S. standard population. Age-specific crude rates are displayed when specific age group data are presented.
• Years of potential life lost (YPLL) is a measure of premature mortality.
• Cost estimates are in 2020 U.S. Dollars and include fatal and nonfatal injury (both hospitalizations and emergency department treat and release visits). Fatal costs account for medical care associated with the fatal injury and statistical life value; nonfatal injury costs include medical care, work loss, and quality of life loss.
• Persons of Hispanic ethnicity may be of any race.

Abbreviations: B=Billions ED=Emergency Department M=Millions NH=Non-Hispanic T=Trillions

Notations:
**indicates unstable value (<20 deaths);
-- indicates suppressed value of non-fatal data (i.e., if <20 unweighted count, <1,200 weighted count, or if the estimate coefficient of variation >30%)

ᵅ CDC does not recommend using NEISS-AIP data for nonfatal firearm injury prevalence estimates at this time. Firearm injuries have distinct geographic patterns, and estimates can be imprecise or change over time when based on a small number of facilities. CDC is working with CPSC to update and expand the NEISS hospital sample  (Go to "About Nonfatal Injury Data” to learn more).

• Fatal data are National Center for Health Statistics - CDC annual mortality data files.
• Nonfatal data are National Electronic Injury Surveillance System-All Injury Program emergency department visits based on a nationally representative probability sample of hospitals.
• Population estimates are from the U.S. Census Bureau.
• Cost data are from multiple sources.
