Residents in Monroe County, Pennsylvania (70 miles), Coconino County, Arizona (68.6), and Parker County, Texas (66.7) travel the most daily miles per person among counties with more than 100,000 residents.

The U.S. cities with the worst air quality in 2023 — mostly in the Midwest — had particle pollution levels two to three times higher than what the World Health Organization (WHO) recommends, according to a new report.
