Countries Ranked by PM2.5 air pollution, mean annual exposure (micrograms per cubic meter)

Showing every country with available data for 2020 • World Bank: EN.ATM.PM25.MC.M3

The indicator page shows only the leaders and the laggards — useful for headlines, but it leaves out the middle of the distribution, which is where most countries actually sit. This page lists every country with reported pm2.5 air pollution, mean annual exposure (micrograms per cubic meter) data for 2020, ranked from highest to lowest, so you can find any country's exact position rather than guessing whether it falls inside the top or bottom ten.

Of the 200 countries reporting, the median value is 20.03, meaning half the world sits above this line and half below. Use the search box below to jump straight to a country, or scroll the full table. Each country name links through to its detailed country × indicator page with the 20-year trend.
