(1) Total Population represents the at-risk populations in counties with ozone monitors. (2) Those 14 and Under and 65 and Over are vulnerable to ozone 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) Adding across rows does not produce valid estimates, i.e. summing pediatric and adult asthma and/or emphysema and chronic bronchitis. (8) Orange: Unhealthy For Sensitive Groups (0.085-0.104 ppm ozone), Red: Unhealthy (0.105-0.124 ppm ozone), and Purple: Very Unhealthy (0.125-0.374 ppm ozone). (9) The weighted average was derived by adding the three years of individual level data (2000-2002), multiplying the sums of each level by the assigned standard weights, i.e. 1=orange, 1.5=red, 2.0=purple, and calculating the average. (10) Grades are as follows: A=0.0, B=0.3-0.9, C=1.0-2.0, D=2.1-3.2, F=3.3+. (11) Two states (KY & TN) expanded the length of their ozone monitoring season and 7 states (AL, CT, FL, MA, ME, VT & WA ) shortened the length of their season. Data from the 2004 report reflects the current ozone season by state. No grades were affected by the changed season lengths, although it may be inaccurate to compare weighted averages from this report with previous reports in those states.
