Quick answer

What does Cities with cleanest air in Finland show?

Raahe, Finland has the lowest pm2.5 — annual mean of the 30 cities compared: 2.98 µg/m³ (cdn.who.int, 2017-12-31).

How this list is built

Every row is a published pm2.5 — annual mean observation, ranked lowest first. The values were observed between 2017 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.

  • Compare the displayed value, unit, source date and geographic grain together.
  • A city label does not change a regional observation into a city measurement.
