Annual population-weighted average concentration of fine particulate matter (PM2.5) in the air, measured in micrograms per cubic meter (µg/m³). Fine particulate matter (PM2.5) are particles with a diameter of 2.5 micrometers or less, which can pose significant health risks. This data excludes natural sources of PM2.5, such as dust and sea salt, to focus on human-caused pollution.
