Key PointsQuestionWhat are the effects of firearm laws on firearm homicides in the United States? FindingsWe found evidence that stronger firearm laws are associated with reductions in firearm homicide rates. The strongest evidence is for laws that strengthen background checks and that require a permit to purchase a firearm. The effect of many of the other specific types of laws is uncertain, specifically laws to curb gun trafficking, improve child safety, ban military-style assault weapons, and restrict firearms in public places. MeaningGiven the magnitude and gravity of firearm homicides in the United States, effective legal and public health policies and adequate funding to enable high-quality research are essential.
