Value-added panel of the World Bank's World Development Indicators (keyless API v2, CC BY 4.0): population-weighted mean annual exposure to ambient PM2.5 fine-particulate air pollution for ~215 economies, 1990-2023, with a WHO 2021 guideline (5 ug/m3) exceedance layer, trailing 1-year and 10-year changes and within-year exposure ranks. Joins on economy_code with the catalog's other World Bank panels.

Column	Type	Description
economy_code	string	ISO 3166-1 alpha-3 economy code (World Bank API field countryiso3code).
economy_name	string	Economy name as published by the World Bank API.
region	string	World Bank region (API field region.value).
income_group	string	World Bank income group (API field incomeLevel.value).
year	integer	Reference year (1990-2023).
pm25_ug_m3	float	Population-weighted mean annual exposure to ambient PM2.5 fine-particulate air pollution (WDI indicator EN.ATM.PM25.MC.M3): the average level of exposure of the nation's population to suspended particulate matter under 2.5 microns in aerodynamic diameter, weighted by population. (unit: micrograms per cubic meter)
pm25_vs_who_guideline_ratio	float	Connector-derived: pm25_ug_m3 divided by the WHO 2021 annual PM2.5 guideline (5 ug/m3). A value of 2.0 means twice the guideline. (unit: ratio)
exceeds_who2021_flag	integer	Connector-derived: 1 where pm25_ug_m3 exceeds the WHO 2021 annual PM2.5 guideline (5 ug/m3), else 0.
pm25_change_1y_pct	float	Trailing 1-year percent change of PM2.5 exposure; null when the base year is absent or zero. (unit: %)
pm25_change_10y_pct	float	Trailing 10-year percent change of PM2.5 exposure (the structural cleanup lens); null when the base year is absent or zero. (unit: %)
pm25_rank	integer	Rank of PM2.5 exposure within the year (1 = highest exposure); null where pm25_ug_m3 is null. (unit: rank)
row_hash	string	Deterministic 12-hex row identity hash (economy_code\|year).
