The values were observed between 2021 and 2024. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify. ## Sources Annual AQ statistics (AirBase & e-Reporting merged) — https://discomap.eea.europa.eu/App/AQViewer/download?f=csv&fqn=Airquality_Dissem.b2g.AirQualityStatistics Swiss Federal Office for the Environment (FOEN/BAFU) and Empa NABEL — https://www.bafu.admin.ch/dam/de/sd-web/wl28-y2TXfSG/Partikelmessungen-NABEL-2024.pdf EEA Air Quality Statistics — PM2.5 annual mean — https://discodata.eea.europa.eu/sql?query=select+%2A+from+%5BAirQualityDataFlows%5D.%5Blatest%5D.%5BAirQualityStatistics%5D+where+component_code+%3D+6001+and+CountryCode+%3D+%27CH%27+and+DataAggregationProcessId+%3D+%27P1Y%27+and+YearOfStatistics+in+%282022%2C+2023%2C+2024%29&p=1&nrOfHits=1000&result=json cdn.who.int — https://cdn.who.int/media/docs/default-source/air-pollution-documents/air-quality-and-health/who_ambient_air_quality_database_version_2024_%28v6.1%29.xlsx?download=true&sfvrsn=c504c0cd_3 ## Cite This citation identifies the ImmigrationDB compilation/page.
