About: Countries by Average PM2.5 Air Quality 2024
Overview of the data behind this chart
Countries ranked by annual mean concentration of PM2.5 fine particulate matter in micrograms per cubic metre in 2024, according to IQAir World Air Quality Report data. Bangladesh and Pakistan consistently record the world's worst average air quality — with annual PM2.5 concentrations exceeding 70 micrograms per cubic metre, more than 14 times the WHO guideline of 5 micrograms. The health burden of this pollution — measured in reduced life expectancy, respiratory disease, and cardiovascular mortality — represents one of the most significant preventable public health crises in both countries.
