The Impact of Granting Undocumented Immigrants Driver's Licenses on Fatal Crashes

This dataset contains the data and code used to replicate the empirical results in the paper:“The Effect of Granting Driver’s Licenses to Undocumented Immigrants on Fatal Crashes.”

The paper examines the causal impact of granting undocumented immigrants driver's licenses on fatal vehicle crashes. Using county-level crash data from the Fatality and Injury Reporting System Tool (FIRST) and exploiting the staggered adoption of driver’s license policies across states, the analysis finds that such reforms increase fatal crashes by approximately 5%, with stronger effects in states with larger undocumented populations. The mechanism analysis suggests that increased risky driving behavior among licensed undocumented immigrants may explain the rise in crashes.
