(1) Total Population represents the at-risk populations in counties with PM2.5 monitors. (2) Those 14 and Under and 65 and Over are vulnerable to PM2.5 and are therefore included. They should not be used as population denominators for disease estimates. (3) Pediatric Asthma estimates are for those under 18 years of age and represent the estimated number of people who currently have asthma in 2002 based on national rates (NHIS) applied to county population estimates (US Census). (4) Adult Asthma estimates are for those 18 years and older and represent the estimated number of people who had asthma during 2002 based on state rates (BRFSS) applied to county population estimates (US Census). (5) Chronic Bronchitis estimates are for adults 18 and over who had been diagnosed with this disease within 2002 based on national rates (NHIS) applied to county population estimates (US Census). (6) Emphysema estimates are for adults 18 and over who have been diagnosed with this disease within their lifetime based on national rates (NHIS) applied to county population estimates (US Census). (7) CV Disease estimates are based on American Heart Association estimates of cardiovascular disease applied to county populations. (8) Adding across rows does not produce valid estimates, i.e. summing pediatric and adult asthma and/or emphysema and chronic bronchitis. (9) The Design Value is the calculated concentration of a pollutant based on the form of the national ambient air quality standard, and is used by EPA to determine whether or not the air quality in a county meets the standard. The source for the Design Values is EPA, at http://www.epa.gov/airtrends/pm25_design_values_2000-2002.pdf. (10) Grades are based on EPA's determination of attainment or nonattainment of the NAAQS for annual PM2.5 levels as of Sept. 2003. Counties in attainment received grades of "Pass"; counties not inattainment received grades of "Fail."
