Most people breathing unhealthy air in Serbia, 2023
1 city in Serbia measured at 2 or more places, ranked by how many people breathed unhealthy air on an average day over the 365 days. The most people breathing unhealthy air: Belgrade, Serbia, about 155K 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 56 of these 365 days. Cities in the United States and Europe have them 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 155K people in this city breathed unhealthy air on an average day of 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.
