Universal Background Checks, Permit Requirements, and Firearm Homicide Rates.

ABSTRACT:

Importance

A loophole in US gun policy is that people can purchase guns from private sellers without going through any background check. Some states have addressed this loophole by requiring universal background checks for all gun sales, either at the point of sale or through a permit system; however, most studies on the effectiveness of universal background checks have not analyzed these 2 policy mechanisms separately.

Objective

To assess the association of point-of-sale background check law and gun permit law, separately, with firearm homicide rates from 1976 through 2022 using the same methods and model specification.

Design, setting, and participants

This cross-sectional study used a difference-in-differences, fixed-effects regression model to evaluate firearm law
