This statistic shows the results of a survey among adult Americans on whether they think that new gun control laws will lead to less mass shootings. The survey was conducted in October 2017. During the survey, 21 percent of respondents stated they think that new gun control laws could reduce the number of mass shootings a great deal.
As of March 19, ***** school shootings were recorded in the United States in 2025, impacting K-12 school grounds and college campuses nationwide. In comparison, there were ** school shooting incidents recorded in 2024. In addition to schools, gun-related violence occurs in many public places within the United States, including workplaces, churches, restaurants, and nightclubs. The source defines school shootings as incidents of gun violence which occurred on school property and at least one person was shot, not including the shooter. School property includes, but is not limited to, buildings, fields, parking lots, stadiums and buses. Accidental discharges of firearms are included, as long as at least one person is shot, but not if the sole shooter is law enforcement or school security.
As of September 4, eight people were killed in mass shootings in the United States in 2024. A total 1,159 victims were fatally injured during mass shootings in the United States between 1982 and September 4, 2024.
In this paper, we investigate the economic consequences of mass shootings. We find that shootings have negative effects on targeted counties' economies. Estimates using three different comparison groups yield similar results. Examining the mechanisms, we find that residents of targeted areas: (i) develop pessimistic views of financial and local business conditions; and (ii) are more likely to report poor mental health, which hinders usual activities such as work, suggesting that shootings lead to decreases in productivity. Further, we find that greater national media coverage of shootings exacerbates their local economic consequences.

The statistic shows the number of victims of the worst mass shootings in western democratic countries from 1966 to 2012. On December 14, 2012, a gunman killed 26 people - 20 of them children aged 5 to 10 - in a shooting at an elementary school in Newtown, Connecticut. He committed suicide afterwards. Gun policy in the USA Over the last few years, mass shootings and accidents with children at shooting ranges have shaped national debates about the gun laws in the United States.
According to the Gallup survey across the United States in January 2014, 40 percent of the U.S. population stated they are totally satisfied with the existing gun laws in the United States, while 31 percent of the respondents stated they are dissatisfied, they want stricter laws.
The survey among American adults, which was conducted by the Pew Research Center in 2012 shortly after the Aurora movie theater shooting, on what they consider more important – the right to bear arms or controlling gun ownership, shows that 47 percent of the participants said the control of gun ownership is more important than the protection of the right to own guns.
The attitude towards gun control varies from generation to generation, 55 percent of the Millennials stated that controlling gun ownership is more important than protecting the gun rights, while 44 percent of the Silent generation stated the same.
The number of homicides by firearms has decreased over the last few years, 11,040 homicides by firearm were counted in 2003, while 9,960 homicides by firearm were counted in 2010. Homicide takes several forms, for example murder but homicide is not always a crime, it also includes affirmative defense, insanity, self-defense or the execution of convicted criminals.
America’s gun policy makes it possible for the American population to have a gun in their home on their own property, all U.S. states have imposed their own firearm restrictions. The percentage of Americans who have a gun in their home shifted from 40 percent in 1996 to 47 percent in 2011.
100 of the mass shootings in the United States between 1982 and September 2024 involved weapons which were obtained legally; a clear majority. Only 16 incidents involved guns that were obtained illegally. Legally owned firearms in the U.S. Within the United States, one must be at least 18 years old in order to purchase shotguns, rifles, and ammunition, and at least 21 years old to purchase all other firearms. Some people may be restricted from owning firearms, such as individuals who have been dishonorably discharged from the military or tourists. Guns must be sold through licensed dealers, and purchasers must undergo a background check. However, the much-discussed “gun show loophole” allows people to purchase firearms from a flea market, gun show, online, or from a personal collector without a background check. The national firearm conversation The right to own a gun in the United States is protected by the 2nd Amendment of the Constitution. While changing a part of the Bill of Rights (the first 10 amendments to the Constitution) would be extremely difficult, the issue of gun rights has become a highly controversial, and highly partisan, topic in the national conversation. For example, a majority of Republicans believe that if legal gun ownership is controlled, that there will not be a difference in the number of mass shootings. In contrast, most Democrats believe the number will decrease.
Handguns are the most common weapon type used in mass shootings in the United States, with a total of 167 different handguns being used in 117 incidents between 1982 and September 2024. These figures are calculated from a total of 151 reported cases over this period, meaning handguns are involved in about 78 percent of mass shootings. The involvement of semi-automatic rifles in mass shootings Owing to their use in several high-profile mass shootings, there has been much public discussion over the suitability or necessity of assault weapons for the purpose of self-defense. While any definition of assault weapon is contentious, semi-automatic rifles are generally the main focus of debates around this issue. Since 1982, there has been a known total 65 mass shootings involving rifles, mostly semi-automatics. This figure is underreported, however, as it excludes the multiple semi-automatic (and fully automatic) rifles used in the 2017 Las Vegas Strip massacre – the worst mass shooting in U.S. history, killing 58 and wounding 546. In fact, semi-automatic rifles were featured in four of the five deadliest mass shootings, being used in the Orlando nightclub massacre, Sandy Hook Elementary massacre and Texas First Baptist Church massacre. Mass shootings and gun control Despite evidence of strict gun control measures reducing the frequency and severity of mass shootings in countries like Australia, citizens in the United States remain deeply divided over the issue. According to a survey about the expected impact of gun laws on the number of mass shootings, a slim majority of Americans believe that gun control measures will have little-to-no effect. Most likely, this opinion is influenced by an underlying commitment among many in the U.S. to the greater importance of protecting gun ownership rights than limiting access to firearms. This sits in sharp contrast to many other developed countries. For example, most Canadians support a ban on civilian owned firearms.

Incidence and death rates of mass homicide by weapon type and sex.
In 2022, there were ****** fatalities caused by injuries related to firearms in the United States, a slight decrease from the previous year. In 2021, there were ****** firearm deaths, the highest number of gun deaths ever recorded in the country. However, this figure has remained relatively high over the past 25 years, with ****** firearm deaths in 1990, and a slight dip in fatalities between 1999 and 2002. Firearms in the United States The right to own firearms in the United States is enshrined in the 2nd Amendment of the U.S. Constitution, and while this right may be seen as quintessentially American, the relationship between Americans and their firearms has become fraught in the last few years. The proliferation of mass shootings in the U.S. has brought the topic of gun control into the national spotlight, with support for banning assault-style weapons a particularly divisive issue among Americans. Gun control With a little less than **** of all Americans owning at least one firearm and the highest rate of civilian gun ownership in the world, it is easy to see how the idea of gun control is a political minefield in the U.S. However, public opinion has begun to shift over the past ten years, and a majority of Americans report that laws governing the sale of firearms should be stricter than they are now.
In 2024, there were a total of 2,532 shootings registered in Rio de Janeiro, Brazil. March was the month with the most shootings in each of the given years, except for 2024 - in that year, there were 254 occurrences, or about 10 percent of the year's total. The lowest number of shootings in the given period occurred in August 2023 when 153 cases were recorded. Police violence in Rio In 2022, the Supreme Court ordered the state government of Rio de Janeiro to come up with a plan to reduce police lethality, as the level of violence in police actions was deemed unacceptable, due to high numbers of casualties and human rights violations. The number of civilians killed as a result of police intervention more than quadrupled between 2013 and 2019, reaching a record number of 1,814 that year. Despite the decrease in comparison to 2019, every year from 2020 to 2022 saw more than 1,200 civilians being killed. Furthermore, it is deemed that there is structural racism in the actions of security forces. For instance, 80 percent of the deaths caused by police interventions in the state during 2023 were of people of color. Shootings and massacres in Rio Civil society and public institutions have made proposals to alleviate this situation. One of them is the ADPF 635 (Allegation of Violation of a Fundamental Precept), also known as ADPF Favelas Case, presented by the Brazilian Socialist Party, and whose preliminary approval took place in June 2020. The measure restricted unplanned police operations in the favelas during the pandemic. Despite its frequent violations, it showed evident results. Shootings fell from 7,368 in 2019 to less than 3,000 in 2024. Over one third of documented shootings in 2024 were due to police operations, while 288 were motivated by murder or attempted murder, the second most common reason. In March 2022, the government of Rio de Janeiro published a plan to reduce deaths during police operations. That year, the State of Rio de Janeiro recorded 92 fewer deaths than the previous year, and the number has fallen every year since.

Incidence rate ratios of firearm to non-firearm post intervention.
The highest number of gun deaths in Romania was reported in 2000, totaling ** deaths. From that moment on, the number of deaths decreased, amounting to ** in 2018.
The share of American households owning at least one firearm has remained relatively steady since 1972, hovering between ** percent and ** percent. In 2024, about ** percent of U.S. households had at least one gun in their possession. Additional information on firearms in the United States Firearms command a higher degree of cultural significance in the United States than any other country in the world. Since the inclusion of the right to bear arms in the Second Amendment to the Constitution of the United States, firearms have held symbolic power beyond their already obvious material power. Despite many Americans being proud gun-owners, a large movement exists within the country in opposition to the freedom afforded to those in possession of these potentially deadly weapons. Those opposed to current gun regulation have sourced their anger from the large number of deaths due to firearms in the country, as well as the high frequency of gun violence apparent in comparison to other developed countries. Furthermore, the United States has fallen victim to a number of mass shootings in the last two decades, most of which have raised questions over the ease at which a person can obtain a firearm. Although this movement holds a significant position in the public political discourse of the United States, meaningful change regarding the legislation dictating the ownership of firearms has not occurred. Critics have pointed to the influence possessed by the National Rifle Association through their lobbying of public officials. The National Rifle Association also lobbies for the interests of firearm manufacturing in the United States, which has continued to rise since a fall in the early 2000s.
Despite fluctuations, namely during the COVID-19 pandemic, the number of homicides in Portugal has generally decreased. In 2024, the Portuguese police registered 89 homicides consummated in the country, down from 97 manslaughter cases reported two years earlier. There were 322 involuntary homicides due to traffic accidents in Portugal, and 24 homicides that happened under other circumstances, such as negligence. Manslaughter cases and incarceration rates in Portugal Portugal had one of lowest homicide rates in Europe as of 2022, at 0.72 homicides per 100,000 inhabitants. The county of the nation’s capital, Lisbon, registered 23 voluntary manslaughter cases in 2024, which represented an increase in comparison to the previous year, but a decrease when compared to pre-pandemic times. In Portugal, the incarceration rate has also overall been on a downward trend. In 2023, there were 118 people incarcerated per 100,000 inhabitants. This rate, however, has risen since the end of the COVID-19 pandemic, but it was in 2015 that the incarceration rate peaked at 137.1. Despite decreasing homicide numbers, domestic violence is increasing in Portugal Domestic violence, which triggers multiple manslaughter cases in Portugal, has been increasing over recent years. In 2023, there were almost 30,500 recorded incidences of domestic violence, which represents a rise compared to pandemic and pre-pandemic years. This type of crime takes place in the domestic environment and between people with a degree of kinship. In 2023, 28 percent of cases occurred between spouses or partners, while seven percent of recorded occurrences concerned ex-spouses or ex-partners. In the same year, 27 percent of domestic violence victims were children or stepchildren of the accused, while the parents or stepparents of the alleged criminals were the victims of domestic violence in over seven percent of cases.
