Death rates from air pollution are highest in low-to-middle income countries

Air pollution is a health and environmental issue across all countries of the world, but with large differences in severity.

In the interactive map we show death rates from air pollution across the world, measured as the number of deaths per 100,000 people of a given country or region.

The burden of air pollution tends to be greater across both low and middle income countries for two reasons: indoor pollution rates tend to be high in low-income countries due to a reliance on solid fuels for cooking; and outdoor air pollution tends to increase as countries industrialize and shift from low-to-middle incomes.
