About the National Data
Baseline: 17.1 deaths per 100,000 population were caused by traumatic brain injuries in 2018
Target: 16.9 per 100,000
Minimal statistical significance
The traumatic brain injury (TBI) definition is consistent with that used in the State Injury Indicators Report. These reports compile injury data voluntarily collected by state health departments. They consolidate data from hospital records, death certificates, and several national surveillance systems and provide the rates of various injuries and related factors. FOR SINGLE DATA YEARS: Death rates are calculated based on the resident population of the United States for the data year involved. For census years (e.g., 2010), population counts enumerated as of April 1 are used. For all other years, populations estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g., July 1, 2011, resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Intercensal population estimates are used in rate calculations for the years between censuses (e.g., 1991–1999, 2001–2009). Race-specific population estimates for 1991 and later use bridged-race categories.
