Methodology Notes

FOR SINGLE DATA YEARS: Emergency department visit rates are calculated using the July 1 estimates of the civilian noninstitutionalized population from the Vintage matching the data year for the postcensal period based on the 2000 census. For example, July 1, 2007 civilian noninstitutionalized population estimates from Vintage 2007 are used as the denominator for 2007 rates. Rates for 2010 are also calculated using the July 1 estimates based on the 2000 census.

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 79.6 to 81.7 due to a revised programming error. The target was adjusted from 55.2 to 57.3 to reflect the revised baseline using the original target-setting method. The target was revised a second time from 57.3 to 56.8 due to a change in the rounding rules for target calculations of Minimal Statistical Significance.
