Comparison at the Average Block Group Level for the Total Population and for Race/Ethnicity and Poverty Strata of Nationwide (a) Proportional and (b) Absolute PM_2.5 Burdens (Tons per Year per Capita) Attributable to Fossil Fuels: United States, 2012–2016

Note. PM_2.5 = fine particulate matter. Absolute burdens from coal-fired electricity-generating units (EGU_cfs) in 2014 data (squares) and burdens calculated after omission of emissions from 92 EGU_cfs that retired operations between 2015 and 2017 (solid circles) are displayed in comparison with mean burdens from a Monte Carlo analysis in which 92 facilities were omitted at random (open circles). Also shown are 95% confidence intervals for the Monte Carlo simulations (gray boxes bounded by black lines).
