Number of persons aged 65 years and over
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.
