Why This Ranking Matters
Examining Pm2.5 Air Pollution across all countries reveals patterns that might not be obvious at the national level. Regional clusters, outlier nations, and historical trajectories all become clearer when the full global picture is assembled in a single ranking.
Global Range
Values range from 4.90 µg/m³ (Finland) to 85.12 µg/m³ (Niger) — a 17-fold difference across 200 countries.
Regional Patterns
African countries dominate this ranking, holding 14 of the top 20 positions. This strong regional concentration suggests shared economic, geographic, or policy factors that drive higher values across the continent.
Values are broadly distributed across countries, with the middle 50% ranging from 12.18 µg/m³ to 29.93 µg/m³. The overall spread from 4.90 µg/m³ to 85.12 µg/m³ reflects significant global variation.
Notable Outliers
The top of the ranking is competitive: Niger and Qatar are separated by only 13%, indicating that the leading positions could shift with updated data.
