Most polluted cities in Gyeonggi-do, South Korea, November 2024

26 cities in Gyeonggi-do, South Korea ranked by their average PM2.5 over the 30 days. Worst: Pubal at 26.7 µg/m³, #82 of 2,572 cities in the world. Cleanest: Gapyeong at 9.9. A city needs measurements on 70% of the days to be ranked.

About 359K people in these 20 cities breathed unhealthy air on an average day of November 2024.

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.
