Sources: Own estimation with data from Coneval (2017), SEDESA (2020), SSA (2020), Dingel and Neiman (2020), INEGI (2015), SEDEMA (2020) and Hammer et al. (2020). The MCMA is comprised of 76 municipalities in the states of Hidalgo, Mexico, and Mexico City. All municipalities (16) from Mexico City are part of the MCMA and are included in the MCMA sample. The Mexico City sample only considers the 14 municipalities for which we have PM2.5 for 2019 and 2020. PM2.5–2019 and PM2.5–14 are calculated from the weighted average of the daily concentrations from 7:00 am to 7:00 pm based on all monitors located within a 7 km radius from each municipality centroid, with weights given by the inverse of the distance between the municipality centroid and each monitor.
