Summary note
This paper explores the effects of the Affordable Care Act (ACA) Medicaid expansions on crime. Using data on all part I criminal offenses from the National Incident-Based Report System and information on health insurance from the American Community Survey, I first run a Differences-in Differences model and then I use a Synthetic Control Approach. I compare crime rates in states that chose to expand Medicaid versus those that chose not to expand, before and after implementation. I find that Medicaid expansions are associated with a significant increase in total crime rate by 0.0734 cases per 1,000 residents among young black adults. I find no significant relationship between Medicaid expansions and crime rates among young black adults below poverty line, young white adults, or young female adults.
