A 2024 study of nations with similar economics and political systems found that between 2000 and 2022, the U.S. accounted for 76 percent of mass shooting incidents and 70 percent of all fatalities with only 33 percent of the combined population. In that same period only four other countries—Canada, Finland, France, and Germany—had more than two incidents compared to 109 in the States. The U.S. tops the list of firearm homicide rates among 65 high-income countries with populations over 10 million. Guns outpace car accidents as the leading cause of death for U.S. children.
What sets the U.S. apart from all other nations?
A weak social safety net
Data from 2019 and 2020 showed counties with the highest levels of poverty saw a higher increase in firearm homicides compared to counties with the lowest poverty levels.
A 2025 study found an increase in the lack of affordable rental homes for low-income people was associated with higher firearm homicide rates.
Mental health is favored deflection by gun rights activists despite the fact that most people with mental health issues are not violent. The lack of investment in mental health care services and barriers to access, however, are a failing of our economic and health care systems. More than half of all U.S. counties have no practicing psychiatrists.
It’s the guns
The gun lobby claims “guns make us safer.” The truth is actually the opposite. More guns means more gun violence. A 2004 Harvard study found that gun availability increases risks of homicide in high-income countries. Estimates from the World Bank placed U.S. gun ownership at 45 percent of all civilian-owned firearms globally with only 5 percent of the population. A 2024 analysis found the U.S. has more than three times the civilian gun ownership than Canada. A recent report found there are likely over 500 million privately-owned firearms with at least 46 percent of American households with at least one firearm.
How are there so many guns in circulation?
Gun manufacturers saw a spike in production since 2019 in comparison from previous decades with 70 million firearm purchases—13 million more than the 2000s and 17 million more than the 1990s. Once a firearm is manufactured and sold, it stays in circulation for extended periods of time with a minimal estimated attrition rate of just 1 percent. The problem is not just legal guns, either. The use of ghost guns grew 1,000 percent since 2017, according to the Department of Justice. Studies of guns recovered from crimes in several major cities found that 87 percent of firearms used to commit crimes were trafficked from other states with weaker gun laws. It is a detail that underscores the need for federal action.
Research shows weaker gun laws contribute to higher rates of gun violence with a 19 percent increase in gun deaths since 1990. States with strengthened gun laws consistently saw declines in firearm-related death rates by 36 percent.
The expansion of open and permitless carry and stand your ground laws create an environment where situations can turn deadly within seconds.
Assault weapons ban expired in 2004
Under the Assault Weapons Ban, the risk of dying in a mass shooting was 70 percent lower.
Since its expiration in September 2004, mass shootings with six or more deaths increased by 347 percent and fatalities up 239 percent. If the ban were not left to expire, it may have prevented 314 of the 448 mass shooting deaths.
Mass shootings
The wide availability of guns, particularly weapons with large magazines, drive the mass shooting epidemic in the U.S. Mass shootings occur dramatically more frequently in the U.S. compared to other developed nations. It is a pattern that is unique to the United States.
Matt is fighting for reforms to reduce gun violence. It is clear the myriad of factors driving gun violence in the U.S. Matt is fighting for a future we can afford to lift families out of poverty, build millions of affordable homes, and expand access to mental health care. But that’s only part of the battle. The nation must confront the gun crisis to save lives.
