Leading Causes of Death

Note Regarding Unintentional Firearm Deaths in 2014

There was a coding error in the 2014 file that increases the number of unintentional firearm deaths (W32-W34: Accidental discharge of firearms) substantially in some states. The error was not technically isolated to any particular state, but because of the nature of the error, data from some states (TN, NC) were affected more than others in 2014. Results for 2014 unintentional firearm deaths should be interpreted with caution.

*New Restrictions for Reporting State-level Death Counts for 2008 and Later

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 National Vital Statistics System (NVSS) state- and county-level death data for years 2008 and later, in order to avoid inadvertent disclosure of cases. Therefore, the National Center for Injury Prevention and Control (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.
