Injury Prevention & Control

The data source for WISQARS Fatal Injury Data is the National Vital Statistics System (NVSS) operated by the National Center for Health Statistics. WISQARS provides death counts and death rates for the United States and by state, county, age, race, Hispanic ethnicity, sex, leading cause of death, injury intent, and injury mechanism categories.

WISQARS can be used to query death data for the years 1999 - 2020, of which the underlying cause of death is specified using ICD-10 codes. The National Center for Health Statistics (NCHS) in an agreement with the National Association of Public Health Statistics and Information Systems (NAPHSIS) has implemented a new, more restrictive rule for reporting state- and county-level death data for years 2008 and later from NVSS in order to avoid inadvertent disclosure of a decedent's identity. Therefore, the Statistics, Programming and Economics Branch, Division of Analysis, Research, and Practice Integration, NCIPC has modified WISQARS to accommodate the new data suppression rule; i.e., no figure, including totals, should be less than 10 in tabulations for sub-national geographic areas, regardless of the number of years combined with the 2008 and later data. Tabulations, charts, and maps produced by WISQARS using only NVSS death data for years prior to 2008 are not affected by this new rule. Therefore, queries of state-level data for years 1999 through 2007 will remain unrestricted; queries of state-level data that include 2008 or later are restricted.
