Gun Policy Analysis

Rand Corporation reviewed thousands of studies to identify all available evidence for the effects of 13 gun policies in the USA on eight outcomes. Updated regularly.

The primary focus of this analysis is the systematic review of 13 broad classes of gun policies in the USA and their effects on eight outcomes. For each class of policies, a synthesis presents and rates the available evidence and describes what conclusions, if any, can be drawn about outcomes. Overall, the authors found statistically significant evidence that seven of the 13 policies affect four of the main outcomes. For the remaining policies, either the policies had inconclusive effects on outcomes or no research about the policies met  inclusion criteria.
