AI-assisted data.
Analysis
The top three in Annual PM2.5 (μg/m³) in 2024 are Bangladesh (79.9), Pakistan (73.7) and India (54.4). The 8 entries in Annual PM2.5 (μg/m³) cover a range of 37.2, from 79.9 down to 42.7. First and second are separated by 6.20, so the leader sits inside the field rather than apart from it. The other 6 are bunched between 42.7 and 54.4 Annual PM2.5 (μg/m³).
