Disease burden is enormous
— respiratory cases reported across the panel — concentrated in winter months and northern states.
Geography matters
districts across states cover the full range from Kerala (~25 µg/m³) to Delhi (~150 µg/m³).
Year-Over-Year Trend
Annual mean across all districts, 2013–2023. National PM2.5 has remained flat at ~59 µg/m³ despite GRAP, BS-VI, and crop-burning bans.
