(1) Counties are ranked by weighted average. See note 9 below.
(2) Total Population represent the at-risk populations in counties with PM2.5 monitors.
(3) Those 18 & under and 65 & over are vulnerable to PM2.5 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 2004 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 2004 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 2004 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) CV disease estimates are based on American Heart Association estimates of cardiovascular disease applied to county populations.
(9) Diabetes 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).
(10) Adding across rows does not produce valid estimates, i.e. summing pediatric and adult asthma and/or emphysema and chronic bronchitis.
(11) The weighted average was derived by counting the number of days in each unhealthful range (orange, red, purple) in each year (2002-2004), multiplying the total in each range by the
assigned standard weights (i.e., 1 for orange, 1.5 for red, 2.0 for purple), and calculating the average.
(12) Grades are assigned by weighted average as follows: A=0.0, B=0.3-0.9, C=1.0-2.0, D=2.1-3.2, F=3.3+.
