Population data was downloaded using the tidycensus package in R for the 2019 ACS using summary variable B01001_001 and the geography flag corresponding to the census block group (CBG). The social distancing index was downloaded from SafeGraph, Inc., and read into R using the SafeGraphR package. The Area Deprivation Index (ADI) was downloaded using the sociome package in R (function get_adi) for census block groups. The SMR is calculated as the observed number of opioid-related overdose deaths divided by the age-adjusted expected counts and aggregated to the CBG
