Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
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.
This Indicator uses Age-Adjustment Groups:
Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.
In 2013, rates for 2007–2009 were revised using intercensal population estimates based on the 2000 and 2010 censuses instead of the postcensal estimates for the denominator. Thus, the original baseline was revised from 17.3 to 17.4. The target was adjusted from 15.6 to 15.7 to reflect the revised baseline using the original target-setting method.
