State-by-State Firearm Law Data
About the State Firearms Laws Database, 1991-2020
The State Firearm Laws project aims to provide researchers with the data necessary to evaluate the effectiveness of various firearm laws. By carefully monitoring how gun legislation impacts firearm-related violence, we can provide policymakers with the evidence they need to make gun ownership safer for everyone.
The database has recently been updated so that it is current through 2020.
