Do Gun Laws Save Lives? A Global Review of the Evidence

What is it about?

This study reviewed 35 research articles published over a decade to understand what causes firearm violence and what prevents it. We compared the United States, where nearly 47,000 people died from firearms in 2023 alone, with countries like Australia, Canada, and members of the European Union that have implemented stricter gun laws. We examined which policies are most effective at reducing deaths, which populations are most at risk, and what behavioral factors contribute to firearm violence. The review found that laws such as universal background checks, permit-to-purchase requirements, and comprehensive national reforms are consistently associated with significant reductions in gun deaths. It also found that men account for the vast majority of both perpetrators and victims, and that intimate partner violence is a major but underreported dimension of the crisis.

Why is it important?

Firearm violence is often treated as a uniquely American political debate, but the evidence shows it is a global public health problem with proven solutions. Countries that have enacted comprehensive reforms have seen mortality reductions of over 60%. The United States ranks in the 93rd percentile globally for firearm deaths, alongside nations experiencing humanitarian crises, despite being one of the wealthiest countries in the world. This review brings together a decade of international evidence to demonstrate that the high rate of gun deaths in the US is not inevitable. It provides a clear, evidence-based blueprint for policymakers, clinicians, and community organizations working to reduce violence and promote peace.
