Where the data comes from

Mortality Data

The mortality data reported in WISQARS comes from death certificate data reported to CDC&s National Center for Health Statistics (NCHS). NCHS collects, compiles, verifies, and prepares these data for release to the public. The process takes approximately 13 months after the end of a given year.

Population Estimates

WISQARS's population estimates of the resident population of the United States for a given year are produced by the U.S. Census Bureau under a collaborative arrangement with the NCHS.

Please note that postcensal population estimates are updated annually, which means that fatal injury rates from WISQARS prior to the update may be different.

Race and Ethnicity

From data year 2001 to 2020, WISQARS used bridged race categories: White, Black, American Indian/Alaska Native, and Asian/Pacific Islander.

Beginning with data year 2018, WISQARS' fatal injury modules include data for the current U.S. Census Bureau's six single race categories: White, Black or African American, American Indian or Alaskan Native, Asian, Native Hawaiian or Other Pacific Islander, and More than One Race.

When exploring fatal data, users have the option to choose one of the following categories depending on the data year(s) and race categories they wish to view:

No Race Categories (available for data years 2001-present):

Bridged Race Category (available for data years 2001-2020):

Single Race Categories (available for data years 2018-present):

The numbers of deaths by external cause of injury were determined using the underlying cause of death codes from the annual mortality data file of CDC' National Vital Statistics System.
