Fig. 2: Country-level estimated per person IQ loss attributable to PM2.5 exposure during neurodevelopment under 2023 air quality conditions.

Population-weighted mean PM2.5 concentrations are used. Darker blue shades represent areas with higher estimated IQ loss while lighter shades represent areas with smaller estimated losses. An equal interval classification scheme was used to represent the data distribution across countries. Map created using the Free and Open Source QGIS66. Basemap created using the Natural Earth dataset (Made with Natural Earth).
