Methodology Notes

FOR MULTIPLE DATA YEARS: Emergency department visit rates are calculated based on sum of July 1 estimates of the civilian noninstitutionalized populations for each of the data years involved (e.g., the denominator of a rate for 2005-2007 combined is the sum of the population estimates for 2005, 2006, and 2007). The population estimates are from the Vintage matching the data year for the postcensal period based on the 2000 census (e.g., July 1, 2005 civilian noninstitutionalized population estimates from Vintage 2005). July 1, 2010 population estimates based on the 2000 census are used for 2010.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

The original baseline was revised from 21.0 to 21.9 due to a revised programming error. The target was adjusted from 13.2 to 13.8 to reflect the revised baseline using the original target-setting method. The target was revised a second time from 13.8 to 13.7 due to a change in the rounding rules for target calculations of Minimal Statistical Significance.
