See how US gun culture compares to the world in 5 graphics
From CNN's Kara Fox, Krystina Shveda, Natalie Croker and Marco Chacon
Ubiquitous gun violence in the United States has left few places unscathed over the decades. Still, many Americans hold their right to bear arms, enshrined in the US Constitution, as sacrosanct. But critics of the Second Amendment say that right threatens another: The right to life.
America's relationship to gun ownership is unique, and its gun culture is a global outlier.
As the tally of gun-related deaths continue to grow daily,
here's a look at how gun culture in the US compares to the rest of the world.
How firearm ownership compares globally
The United States is the only nation in the world where civilian guns outnumber people.
The US has the highest firearm homicide rate in the developed world
In 2019, the number of US deaths from gun violence was about 4 per 100,000 people. That’s 18 times the average rate in other developed countries. Multiple studies show access to guns contributes to higher firearm-related homicide rates.
Almost a third of US adults believe there would be less crime if more people owned guns, according to an April 2021 Pew survey. However, multiple studies show that where people have easy access to firearms, gun-related deaths tend to be more frequent, including by suicide, homicide and unintentional injuries.
It is then unsurprising that the US has more deaths from gun violence than any other developed country per capita. The rate in the US is eight times greater than in Canada, which has the seventh highest rate of gun ownership in the world; 22 times higher than in the European Union and 23 times greater than in Australia, according to Institute for Health Metrics and Evaluation (IHME) data from 2019.
The gun-related homicide rate in Washington, DC -- the highest of any US state or district -- is close to levels in Brazil, which ranks sixth highest in the world for gun-related homicides, according to the IHME figures.
Globally, countries in Latin America and the Caribbean suffer from the highest rates of firearm homicides, with El Salvador, Venezuela, Guatemala, Colombia and Honduras topping the charts.
Drug cartel activities and the presence of firearms from old conflicts are both contributing factors, according to the 2018 Global Mortality From Firearms, 1990-2016, study.
But gun-related violence in Latin America and the Caribbean is also exacerbated by weapons that come from the US. About 200,000 firearms from America cross Mexico's border every year, according to a February 2021 US government accountability office report, citing the Mexican government.
In 2019, about 68% of firearms seized by law enforcement in Mexico and sent to the ATF for identification were traced back to the US. And around half of guns the ATF checked after they've been seized in Belize, El Salvador, Honduras and Panama were manufactured in or officially imported to the US.
While personal safety tops the list of reasons why American gun owners say they own a firearm, 63% of US gun-related deaths are self-inflicted.
Over 23,000 Americans died from self-inflicted gunshot wounds in 2019. That number accounts for 44% of the gun suicides globally and dwarfs suicide totals in any other country in the world.
At six firearm suicides per 100,000 people, the US rate of suicide is, on average, seven times higher than in other developed nations. Globally, the US rate is only lower than in Greenland, an autonomous Danish territory with relatively high gun ownership (22 guns per 100 people).
Multiple studies have reported an association between gun ownership and gun-related suicides.
One of those studies, conducted by researchers at Stanford University, found that men who owned handguns were almost eight times as likely to die of self-inflicted gunshot wounds as men who didn't own a gun. Women who owned handguns were 35 times as likely to die by firearm suicide, compared to those who didn't, according to the 2020 study, which surveyed 26 million California residents over a more than 11-year period.
No other developed nation has mass shootings at the same scale or frequency as the US
Half of the world’s developed countries had at least one public mass shooting between 1998 and 2019.* But no other nation saw more than eight incidents over 22 years, while the United States had over 100 — with almost 2,000 people killed or injured.
Number of mass shooting casualties, by year
Gun-related deaths reduced after the introduction of stricter laws in these countries
Shortly after a mass shooting in Tasmania, Australia banned rapid-fire rifles and shotguns and tightened licensing rules. Over the next decade, gun deaths dropped by 51%.
A decade of rising gun deaths in South Africa prompted the government to pass new laws prohibiting certain firearms, mandating background checks and tightening licensing requirements, which capped gun ownership numbers.
A mass shooting in 1996 prompted the UK Parliament to further tighten the country's gun laws and ban private gun ownership.* Gun-related deaths fell by a quarter over the decade that followed.
Three mass shootings in three years prompted Finland to overhaul its gun laws in 2011. Gun deaths were already falling, yet there was an additional 17% drop between 2011 and 2019.
After a 2002 shooting by a 19-year-old, Germany's parliament passed gun restrictions for young people, including banning large-caliber weapon sales and requiring psychological evaluation before
Meanwhile, countries that have introduced laws to reduce gun-related deaths have achieved significant changes.
A decade of gun violence, culminating with the Port Arthur massacre in 1996, prompted the Australian government to take action.
Less than two weeks after Australia's worst mass shooting, the federal government implemented a new program, banning rapid-fire rifles and shotguns, and unifying gun owner licensing and registrations across the country. In the next 10 years gun deaths in Australia fell by more than 50%. A 2010 study found the government's 1997 buyback program -- part of the overall reform -- led to an average drop in firearm suicide rates of 74% in the five years that followed.
Other countries are also showing promising results after changing their gun laws. In South Africa, gun-related deaths almost halved over a 10-year-period after new gun legislation, the Firearms Control Act of 2000, went into force in July 2004. The new laws made it much more difficult to obtain a firearm.
In New Zealand, gun laws were swiftly amended after the 2019 Christchurch mosque shootings. Just 24 hours after the attack, in which 51 people were killed,
Prime Minister Jacinda Ardern announced that the law would change. New Zealand's parliament voted almost unanimously to change the country's gun laws less than a month later, banning all military-style semi-automatic weapons.
Britain tightened its gun laws and banned most private handgun ownership after a mass shooting in 1996, a move that saw gun deaths drop by almost a quarter over a decade. In August 2021, a licensed firearms holder killed five people in Plymouth, England, marking the worst mass shooting since 2010. After the incident, police said the gunman's firearm license had been returned to him just months after it was revoked,
due to assault accusations. The British government then asked police to review their licensing practices and said that they would be bringing forward new guidance to improve background procedures, including social media checks.
Many countries around the world have been able to tackle gun violence. Yet, despite the thousands of lost lives in the US, only around half of US adults favor stricter gun laws, according to the recent Pew survey, and political reform remains at a standstill. The deadly cycle of violence seems destined to continue.
