Living in Nagpur is the population-level health-equivalent of smoking 2.5 cigarettes a day — roughly 908 cigarettes a year. On average, that chronic exposure shortens life expectancy by about 4.9 years per resident.

Cigarette-equivalence (Berkeley Earth 2015) and life-years lost (EPIC AQLI) are peer-reviewed communication heuristics, not clinical diagnoses. Full sources linked on the methodology page.

What the numbers say

Overview

Living in Nagpur carries a daily PM2.5 dose that Berkeley Earth compares to 2.5 cigarettes a day. Over a year, residents absorb the equivalent of 908 cigarettes.

The data story

EPIC's AQLI research attributes about 4.9 life-years lost per person from this chronic exposure. The WHO Air Quality Guideline was met on just 11 of 1,844 days (0.6%); 339 days (18.4%) exceeded even the 75 µg/m³ Interim Target-1 threshold.

Why this pattern

The burden concentrates in December — when the average cigarette-equivalent climbs to 3.4/day — and eases in July (1.5/day). Globally, WHO attributes 68% of PM2.5 deaths to heart disease and stroke, with the remainder split across COPD, childhood ALRI, and lung cancer.

What to do with this

Cigarette-equivalence is a communication tool, not a medical verdict. Still, the direction is clear: time indoors with a HEPA unit and a good-fit mask outdoors during the 1,435 days (77.8%) above WHO IT-3 meaningfully lowers exposure — especially for pregnant residents and children under 5.
