The values were observed between 2014 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 official validated air-quality station bulk; no exact target station-period input found — https://aqportal.discomap.eea.europa.eu/download-data/ European Environment Agency — https://air.discomap.eea.europa.eu/arcgis/rest/services/AirQuality/AQ_Statistics_WM/MapServer/0/query EEA air quality statistics — PT PM2.5 annual mean 2024 (station Joaquim Magalhães) — https://air.discomap.eea.europa.eu/arcgis/rest/services/AirQuality/AQ_Statistics_WM/MapServer/0/query?where=Country_ISO%3D%27PT%27%20AND%20AirPollutant%3D%27PM2.5%27%20AND%20YearOfStatistics%3D2024&outFields=AirPollutant,AirPollutionLevel,Country_ISO,StationName,YearOfStatistics,UnitOfAirpollutionLevel,ReportingMetric,LatitudeOfMeasurementStation,LongitudeOfMeasurementStation,DataCoverage,Preliminary&returnGeometry=false&f=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 Annual AQ statistics (AirBase & e-Reporting merged) — https://discomap.eea.europa.eu/App/AQViewer/download?f=csv&fqn=Airquality_Dissem.b2g.AirQualityStatistics ## Cite This citation identifies the ImmigrationDB compilation/page.
