Recent Studies on Gun Violence Prevention:

(2016) “Firearm legislation and firearm mortality in the USA: a cross-sectional, state-level study“ The Lancet, Mar. 10, 2016, finds that three measures would be most effective in reducing firearm deaths: universal background checks, ammunition background checks, and identification requirements for firearms such as microstamping ammunition.

(2017) "New Stanford study analyzes recent research on causes of gun violence," Stanford News, Stanford University,

"Consensus is growing in recent research evaluating the impact of right-to-carry concealed handgun laws, showing that they increase violent crime, despite what older research says."

(2017) “Firearm Laws and Firearm Homicides: A Systematic Review” JAMA Jan. 2017 “We 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.”

(2017) "More Guns Do Not Stop More Crimes, Evidence Shows" Scientific American, Oct. 2017. This narrative discusses various popular claims related to crime and gun ownership and how they compare to the evidence.


(2018) "What Do We Know About the Association Between Firearm Legislation and Firearm-Related Injuries?", Epidemiologic Reviews, "Evidence from 130 studies in 10 countries suggests that in certain nations the simultaneous implementation of laws targeting multiple firearms restrictions is associated with reductions in firearm deaths."

(2018) “What Science Tells Us About the Effects of Gun Policies,” RAND Corporation

This broad meta-analysis covers a number of studies related to specific gun policies and ultimately concludes that most policies lack solid supportive data. Still, three policies were found to have at least “moderate” supporting evidence of effectiveness in reducing gun injuries and deaths: child access prevention laws, improved background checks laws, and prohibitions associated with mental illness. One additional policy, stand-your-ground type laws were found to have moderate evidence of increasing gun related homicides and injuries.

(2019) “What Are the Most Effective Policies in Reducing Gun Homicides” Rockefeller Institute of Government, "Our analysis found three priority pieces of legislation that would have the greatest impact in reducing overall firearm homicide rates: 1. Universal background checks. 2. Prohibition of gun possession by people with a history of any violent misdemeanor, threatened violence, serious alcohol-related crime, or subject to a domestic violence restraining order. This must be accompanied by: (1) a requirement that firearms already in their possession be surrendered; (2) a procedure for confiscating guns if they are not relinquished voluntarily; and (3) procedures for confiscating guns in situations where a person becomes prohibited from owning firearms after having passed an earlier background check. 3. Laws that give discretion to law enforcement officials (“may issue” laws) in denying concealed carry permits to those who are at high risk for violence, especially those who have a criminal history of violence."

(2019) “State Gun Laws and Pediatric Firearm-Related Mortality, Pediatrics, Journal of the American Academy of Pediatrics, “We found that states with stricter firearm legislation had lower rates of firearm-related death in children. This association remained after population-based adjustment for sociodemographic factors and gun ownership. Furthermore, states with laws requiring universal background checks for firearm purchase also had lower rates of pediatric firearm-related deaths.”


(2019) Quinnipiac Poll, “There is no division, however, as Ohio voters support 90 - 8 percent, including 87 - 11 percent among gun owners, background checks for all gun buyers.”

(2020) RAND Corporation, "Gun Policy in America"

This comprehensive site explores a wide variety of gun violence issues and scientific studies, including analysis of which types of legislation have been shown, by well designed and executed scientific research, to be most effective. This is an excellent and impressive overall resource.
