PM2.5 annual mean

Annual mean concentration of fine particulate matter under 2.5 micrometres, estimated as the arithmetic mean of validated EEA 1 km grid cells within 10 km of the reviewed city point.

The reference is the median of the 36 cities published here, not a European average. Eurostat's EU aggregates are not collected yet, and deriving one from these cities would invent a figure no source publishes.

Ordered best first

This measure has stated that a lower value is better for a household choosing where to settle, so the order and the colour follow from it. Cities with the same value share a rank. This orders one measure; it is not a ranking of cities.

Every value is published at the same geographic level: Point. Period 2024 annual mean. Confidence confidence grade B throughout.

Each bar grows from the median towards the side its value falls on. The two halves are scaled independently, so the lowest and highest values reach their ends even when the spread is uneven: a bar's length is comparable with others on the same side of the median, not across it.

How this measure is built

Definition
Annual mean concentration of fine particulate matter under 2.5 micrometres, estimated as the arithmetic mean of validated EEA 1 km grid cells within 10 km of the reviewed city point.
Calculation
unweighted arithmetic mean of the 313 valid 1 km cells whose centre lies within 10 km of the reviewed city point (47.38, 8.54), transformed to EPSG:3035 as (4210676.2, 2697353.8); no-data cells excluded, no station or wider-radius fallback
Limits
This is a model-assisted circular-area estimate, not a monitoring-station reading, municipality average or regulatory-compliance assessment. The 10 km radius, grid resolution, valid-cell count and confidence B must remain visible.
Position
The median, the gap and the rank are arithmetic over the values in this table and can be recomputed from it. They are not a score, carry no weighting, and combine with nothing else on the site.Read the method
