What the numbers say

  • 양양군, South Korea leads at 9.06 µg/m³.
  • 서귀포시, South Korea sits at the other end with 12 µg/m³.
  • The middle of this ranking is 11.15 µg/m³, across 30 places that publish the metric.
  • The spread between first and last is 2.94 µg/m³.

What this measures

Every row is a published pm2.5 — annual mean observation, ranked lowest first. The values were observed in 2024. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value.

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