From: Counterfactual time series analysis of short-term change in air pollution following the COVID-19 state of emergency in the United States

Figure 3

Median change in PM2.5 following the state-level emergency declaration for each state (\(\Delta_{j}\)). A negative estimated value of \(\Delta_{j}\) indicates that air pollution levels declined as a result of the state-level emergency declaration. This figure was created using open source software R 4.1.0 (https://cran.r-project.org/). The base US map was used by using the R package: rnaturalearthhires ().
