Tools and Data from the Gun Policy in America Initiative

The Gun Policy in America initiative developed tools and resources to help advance research on the effects of gun policies. These include a new data set of state laws and their variants, and an online tool exploring expert views on how different combinations of policies are likely to affect outcomes.

  • State Firearm Law Navigator

    Research on the effects of gun laws requires good data on when and where different types of laws have been implemented.
