From The Commonwealth Fund announcement about its report, "Comparing Deaths from Gun Violence in the U.S. with Other Countries" (Oct. 30, 2024): 

Gun violence kills more people in the United States than in almost any other country. It also costs Americans an estimated $557 billion in 2022, an average of $1,700 per taxpayer. Gun violence — declared a public health crisis by the U.S. surgeon general in June 2024* — is also the leading cause of death for children and a contributor to rising preventable mortality rates.

In a series of charts, Commonwealth Fund researchers illustrate how gun-related deaths in the U.S. compare with other countries and territories around the world. They show that nearly every U.S. state has a higher firearm mortality rate than most other countries.

Explore the charts to learn more, including how the gun violence epidemic impacts children and adolescents, women, and people of color.

And from the CF report itself:

Highlights

Globally, the U.S. ranks at the 93rd percentile for overall firearm mortality, 92nd percentile for children and teens, and 96th percentile for women.

The U.S. has among the highest overall firearm mortality rates, as well as among the highest firearm mortality rates for children, adolescents, and women, both globally and among high-income countries.

Nearly all U.S. states have a higher firearm mortality rate than most other countries. Death rates due to physical violence by firearm in U.S. states are closer to rates seen in countries experiencing active conflict.

Black and American Indian and Alaska Native (AIAN) people have the highest firearm mortality rates of any racial or ethnic group. 

I've blogged on this public-health crisis before (here, here, and here), but I don't see a practical solution in part because we have dug an enormous hole for ourselves:

Based on NICS background data and manufacturing records, it is estimated that there are 500 million civilian-owned firearms in the U.S. Only 6.06 million firearms are registered in America (the U.S. does not require registration for all firearms). Estimates show that 82,880,000 people own at least one firearm in 2023. [source]

And the Supreme Court has mostly boarded up that hole with its hide-bound reading of the Second Amendment. Cf. Congressional Research Service, The Second Amendment at the Supreme Court: Challenges to Federal Gun Laws (updated July 8, 2024). 

And yet . . . something's got to change. As Justice Robert Jackson wrote (in dissent in Terminiello, a free-speech case), "There is danger that, if the Court does not temper its doctrinaire logic with a little practical wisdom, it will convert the constitutional Bill of Rights into a suicide pact."
