(1) Cities are ranked by using the highest weighted average for any county within that metropolitan area.
(2)
Total Population represents the at-risk populations for all counties within the respective MSAs.
(3) Those
18 & Under and 65 & Over are vulnerable to ozone and are therefore included. They should not be used as population denominators for disease estimates.
(4)
Pediatric Asthma estimates are for those under 18 years of age and represent the estimated number of people who had asthma in 2003 based on national rates (NHIS) applied to county population estimates (US Census).
(5)
Adult Asthma estimates are for those 18 years and older and represent the estimated number of people who had asthma during 2003 based on state rates (BRFSS) applied to county population estimates (US Census).
(6)
Chronic Bronchitis estimates are for adults 18 and over who had been diagnosed within 2003 based on national rates (NHIS) applied to county population estimates (US Census).
(7)
Emphysema estimates are for adults 18 and over who have been diagnosed within their lifetime based on national rates (NHIS) applied to county population estimates (US Census).
(8) Adding across rows does not produce valid estimates, i.e. summing pediatric and adult asthma and/or emphysema and chronic bronchitis.
