The average red states’ air is 10 percent cleaner than the average blue state, according to Environmental Protection Agency (EPA) data analyzed by The Daily Caller News Foundation.
The EPA data tracks average exposure to small particulates, which kill roughly 5.5 million people globally every year and cause most asthma. Particulate emissions have fallen by 35 percent since the year 2000, mostly in states that voted for Republicans.
The state with the cleanest air in America was Wyoming, which had a population-weighted average exposure to particulates of five. California’s air was the nation’s dirtiest, with an average weighted exposure of 12.5. The average red state had a weighted exposure of 8.31 while the average blue state had an exposure of 9.05. Adjusted for scale, this means that red states have air that is 9.87 percent cleaner than blue states.
