SmogRank / World / United States / Georgia / July 2023
Most polluted cities in Georgia, United States, July 2023
15 cities in Georgia, United States ranked by their average PM2.5 over the 31 days. Worst: Candler-McAfee at 14.9 µg/m³, #132 of 1,375 cities in the world. Cleanest: Augusta at 10.4. A city needs measurements on 70% of the days to be ranked.
OpenAQ's archive, where our readings come from, has almost none for one of these days. Cities in the United States and Europe have it from the EPA's and the European Environment Agency's own records of the same monitors; elsewhere a city's average is over its other days. Why.
About 37K people in these 2 cities breathed unhealthy air on an average day of July 2023.
Ranked by people: each city's population times its share of unhealthy days, those with a daily mean over 35.4 µg/m³ (US AQI 101+). That is how many people living there breathed unhealthy air on an average day. Only cities measured at 2 or more places at least 3 km apart are ranked: one monitor shouldn't speak for a whole city. Population is the city itself, not its wider metro area.
