Definition

What this measures

Population-weighted exposure to ambient PM2.5 pollution is defined as the average level of exposure of a nation's population to concentrations of suspended particles measuring less than 2.5 microns in aerodynamic diameter, which are capable of penetrating deep into the respiratory tract and causing severe health damage. Exposure is calculated by weighting mean annual concentrations of PM2.5 by population in both urban and rural areas. Source: Global Burden of Disease study, compiled by the World Bank.

Quality and confidence
Model-based estimates combining satellite retrievals, chemical transport models and ground monitors. Updates are infrequent and the series is re-estimated at each release.
Ingestion rejects values outside 0 to 500 micrograms per cubic metre.
34 periods with values for this geography, 1990 to 2023.
Revisions
Values reported for the latest period (2023) by each source revision ingested. Earlier rows are never deleted; the newest ingested row is shown as current.
