Data notes & caveats
The measure is age-standardized deaths attributed to household and ambient air pollution per 100,000 people. The World Health Statistics annex can publish comparable estimates or primary reported data; modeled values may include adjustment and uncertainty, and country series can differ from national publications.
Methodology
The ranking uses the World Health Statistics 2026 Statistical Annex measure for age-standardized mortality attributed to household and ambient air pollution in 2021. Regional and global summary groups are excluded, and countries and reporting areas are ordered from highest to lowest. Equal values retain tied ranks. Compact labels are rounded consistently for readability.
Source consistency notes
All entries use the same WHO measure, 2021 reference year, total-population grouping and measurement unit (deaths per 100,000 population).
