Fig. 7: Decomposition of changes in marginal health benefits of PM2.5 mitigation.
From: Reversal of trends in global fine particulate matter air pollution

The sensitivity of PM2.5 attributable mortality to 1 μg/m3 difference in PM2.5 (normalized to 2011) over each region during 1998–2019 are decomposed to changes from (a) PM2.5 exposure, (b) population age structure, (c) baseline mortality rate, and (d) population growth. Dotted lines are the time series of population-weighted PM2.5 (also normalized to 2011) on a flipped Y-axis.
