Most people breathing unhealthy air in Serbia, 2024

1 city in Serbia measured at 2 or more places, ranked by how many people breathed unhealthy air on an average day over the 366 days. The most people breathing unhealthy air: Belgrade, Serbia, about 190K on an average day. 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 190K people in this city breathed unhealthy air on an average day of 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.
