(1) 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). (2) 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). (3) 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). (4) 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). (5) CV Disease estimates are based on American Heart Association estimates of cardiovascular disease applied to county populations. (6) 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. (7) Total Population represents the at-risk populations in counties/cities with ozone or PM2.5 pollution monitors; it does not represent the entire states' sensitive populations. (8) Adding across rows does not produce valid estimates, i.e. summing pediatric and adult asthma and/or emphysema and chronic bronchitis.
