In 2023, the FBI reported that there were 9,284 Black murder victims in the United States and 7,289 white murder victims. In comparison, there were 554 murder victims of unknown race and 586 victims of another race. Victims of inequality? In recent years, the role of racial inequality in violent crimes such as robberies, assaults, and homicides has gained public attention. In particular, the issue of police brutality has led to increasing attention following the murder of George Floyd, an African American who was killed by a Minneapolis police officer. Studies show that the rate of fatal police shootings for Black Americans was more than double the rate reported of other races. Crime reporting National crime data in the United States is based off the Federal Bureau of Investigation’s new crime reporting system, which requires law enforcement agencies to self-report their data in detail. Due to the recent implementation of this system, less crime data has been reported, with some states such as Delaware and Pennsylvania declining to report any data to the FBI at all in the last few years, suggesting that the Bureau's data may not fully reflect accurate information on crime in the United States.

Number, percentage and rate (per 100,000 population) of homicide victims, by racialized identity group (total, by racialized identity group; racialized identity group; South Asian; Chinese; Black; Filipino; Arab; Latin American; Southeast Asian; West Asian; Korean; Japanese; other racialized identity group; multiple racialized identity; racialized identity, but racialized identity group is unknown; rest of the population; unknown racialized identity group), gender (all genders; male; female; gender unknown) and region (Canada; Atlantic region; Quebec; Ontario; Prairies region; British Columbia; territories), 2019 to 2023.

In 2023, 8,842 murderers in the United States were white, while 6,405 were Black. A further 461 murderers were of another race, including American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. However, not all law enforcement agencies submitted homicide data to the FBI in 2023, meaning there may be more murder offenders of each race than depicted. While the majority of circumstances behind murders in the U.S. are unknown, narcotics, robberies, and gang killings are most commonly identified.

Number, percentage and rate (per 100,000 population) of homicide victims, by gender (all genders; male; female; gender unknown) and Indigenous identity (total; Indigenous identity; non-Indigenous identity; unknown Indigenous identity), Canada, provinces and territories, 2014 to 2020.

How many criminal homicides were there in the U.S.? In 2023, there were 19,252 reported cases of murder or non-negligent manslaughter in the United States, a decrease from 21,781 cases reported in the previous year. This figure has also decreased in comparison to 1991, when there were 24,700 reported murder and non-negligent manslaughter cases. Murder vs. Manslaughter While it is can be easy to confuse the two terms, murder and nonnegligent manslaughter are two different crimes. While there is some variation from state to state, murder is usually seen as having some planning or forethought involved in the crime, while manslaughter is considered to be a “crime of passion,” with the absence of forethought. Courts tend to differentiate between the states of mind of the accused when bringing manslaughter or murder charges against them. The victims In the United States, there were far more male murder victims than female murder victims, and Black victims made up a large proportion of the total number of victims. Additionally, many murders in the U.S. are perpetrated by either an acquaintance of the victim or a stranger.

OVERVIEW

2019 had the most mass killings since at least the 1970s, according to the Associated Press/USA TODAY/Northeastern University Mass Killings Database.

In all, there were 45 mass killings, defined as when four or more people are killed excluding the perpetrator. Of those, 33 were mass shootings . This summer was especially violent, with three high-profile public mass shootings occurring in the span of just four weeks, leaving 38 killed and 66 injured.

A total of 229 people died in mass killings in 2019.

The AP's analysis found that more than 50% of the incidents were family annihilations, which is similar to prior years. Although they are far less common, the 9 public mass shootings during the year were the most deadly type of mass murder, resulting in 73 people's deaths, not including the assailants.

One-third of the offenders died at the scene of the killing or soon after, half from suicides.

About this Dataset

The Associated Press/USA TODAY/Northeastern University Mass Killings database tracks all U.S. homicides since 2006 involving four or more people killed (not including the offender) over a short period of time (24 hours) regardless of weapon, location, victim-offender relationship or motive. The database includes information on these and other characteristics concerning the incidents, offenders, and victims.

The AP/USA TODAY/Northeastern database represents the most complete tracking of mass murders by the above definition currently available. Other efforts, such as the Gun Violence Archive or Everytown for Gun Safety may include events that do not meet our criteria, but a review of these sites and others indicates that this database contains every event that matches the definition, including some not tracked by other organizations.

This data will be updated periodically and can be used as an ongoing resource to help cover these events.

Definition of "mass murder"

Mass murder is defined as the intentional killing of four or more victims by any means within a 24-hour period, excluding the deaths of unborn children and the offender(s). The standard of four or more dead was initially set by the FBI.

This definition does not exclude cases based on method (e.g., shootings only), type or motivation (e.g., public only), victim-offender relationship (e.g., strangers only), or number of locations (e.g., one). The time frame of 24 hours was chosen to eliminate conflation with spree killers, who kill multiple victims in quick succession in different locations or incidents, and to satisfy the traditional requirement of occurring in a “single incident.”

Offenders who commit mass murder during a spree (before or after committing additional homicides) are included in the database, and all victims within seven days of the mass murder are included in the victim count. Negligent homicides related to driving under the influence or accidental fires are excluded due to the lack of offender intent. Only incidents occurring within the 50 states and Washington D.C. are considered.

Methodology

Project researchers first identified potential incidents using the Federal Bureau of Investigation’s Supplementary Homicide Reports (SHR). Homicide incidents in the SHR were flagged as potential mass murder cases if four or more victims were reported on the same record, and the type of death was murder or non-negligent manslaughter.

Cases were subsequently verified utilizing media accounts, court documents, academic journal articles, books, and local law enforcement records obtained through Freedom of Information Act (FOIA) requests. Each data point was corroborated by multiple sources, which were compiled into a single document to assess the quality of information.

In case(s) of contradiction among sources, official law enforcement or court records were used, when available, followed by the most recent media or academic source.

Case information was subsequently compared with every other known mass murder database to ensure reliability and validity. Incidents listed in the SHR that could not be independently verified were excluded from the database.

Project researchers also conducted extensive searches for incidents not reported in the SHR during the time period, utilizing internet search engines, Lexis-Nexis, and Newspapers.com. Search terms include: [number] dead, [number] killed, [number] slain, [number] murdered, [number] homicide, mass murder, mass shooting, massacre, rampage, family killing, familicide, and arson murder. Offender, victim, and location names were also directly searched when available.

This project started at USA TODAY in 2012.

Between 2021 and 2024, the homicide rate for people of the Black ethnic group was **** homicides per million population in England and Wales, far higher than that of the white ethnic group, which was *** victims per million population for the same time period.

Number, rate and percentage changes in rates of homicide victims, Canada, provinces and territories, 1961 to 2023.

In 2023/24 there were 570 homicides that took place in England and Wales, with 370 of these victims belonging to the white ethnic group. In this reporting year, 95 homicide victims were Black, with a further 89 belonging to other ethnic groups, and 16 not known.

In the United States, Black people have higher rates of gun homicide than White people across all age groups. As of 2022, gun homicide rates were highest among Black people aged between 15 and 24 years, at ***** gun homicides per 100,000 of the population. In comparison, there were only **** gun homicides per 100,000 of the White population within this age range. However, the risk for gun homicide was greatest among all adolescents and adults between the ages of 15 to 44 in that year. The impact of guns on young Americans In the last few years, firearms have become the leading cause of death for American children and teenagers aged one to 19 years old, accounting for more deaths than car crashes and diseases. School shootings also remain on the rise recently, with the U.S. recording ** times as many school shootings than other high-income nations from 2009 to 2018. Black students in particular experience a disproportionately high number of school shootings relative to their population, and K-12 teachers at schools made up mostly of students of color are more likely to report feeling afraid that they or their students would be a victim of attack or harm. The right to bear arms Despite increasingly high rates of gun-related violence, gun ownership remains a significant part of American culture, largely due to the fact that the right to bear arms is written into the U.S. Constitution. Although firearms are the most common murder weapon used in the U.S., accounting for approximately ****** homicides in 2022, almost **** of American households have at least one firearm in their possession. Consequently, it is evident that firearms remain easily accessible nationwide, even though gun laws may vary from state to state. However, the topic of gun control still causes political controversy, as the majority of Republicans agree that it is more important to protect the right of Americans to own guns, while Democrats are more inclined to believe that it is more important to limit gun ownership.

In 2022, the state of Bahia reported the largest number of homicides in Brazil. That year, ***** homicides were recorded in this northeastern state. Bahia was followed by the state of Rio de Janeiro, with ***** murders reported. Despite that, the number of homicides in Brazil reached the lowest figure that year since at least 2006, totaling ******. Homicide targets Data shows that homicides affected men disproportionaly more than women in this South American country. Considering the over ****** homicides registered in Brazil in 2022, nearly ** percent had men as victims. Again, it is important to remember the deterioration of data quality, specially in the case of femicides: there was a woman victim of violent death with no clear cause for every woman victim of homicide in Brazil. In that regard, the Brazilian states of Mato Grosso and Rondônia had the highest femicide rates. At least ***** of every 100,000 women who lived in those territories were murdered on account of their gender in 2023. Not only women, but the number of black and brown people murdered in Brazil had been growing throughout the years up until 2017, revealing that minorities are increasingly becoming the targets of violence. In 2022, nearly ****** people of color were killed in Brazil, over ***** times the number of non-black or non-brown people. Police Violence Police brutality has been gaining attention from the media, especially after George Floyd violent death in 2020. In Brazil, police violence, particularly in poor areas, such as favelas, is an old and well-known problem that affects society as a whole. Figures have shown that the number of civilians killed by police officers in Brazil surpassed ***** in both 2021 and 2022. Coincidentally, Rio de Janeiro and Bahia, the Brazilian states with the highest number of homicides, are also the ones with the highest number of people killed by the police. In Rio, the state with the second-highest figure, people of color were the main victims of deadly police interventions.

Sadly, the trend of fatal police shootings in the United States seems to only be increasing, with a total 1,173 civilians having been shot, 248 of whom were Black, as of December 2024. In 2023, there were 1,164 fatal police shootings. Additionally, the rate of fatal police shootings among Black Americans was much higher than that for any other ethnicity, standing at 6.1 fatal shootings per million of the population per year between 2015 and 2024. Police brutality in the U.S. In recent years, particularly since the fatal shooting of Michael Brown in Ferguson, Missouri in 2014, police brutality has become a hot button issue in the United States. The number of homicides committed by police in the United States is often compared to those in countries such as England, where the number is significantly lower. Black Lives Matter The Black Lives Matter Movement, formed in 2013, has been a vocal part of the movement against police brutality in the U.S. by organizing “die-ins”, marches, and demonstrations in response to the killings of black men and women by police. While Black Lives Matter has become a controversial movement within the U.S., it has brought more attention to the number and frequency of police shootings of civilians.

Lynching in the United States is estimated to have claimed over 4.7 thousand lives between 1882 and 1968, and just under 3.5 thousand of these victims were black. Today, lynching is more commonly associated with racial oppression, particularly in the south, however, in early years, victims were more commonly white (specifically Mexican), and lynchings were more frequent in western territories and along the southern border. It was only after Reconstruction's end where the lynching of black people became more prevalent, and was arguably the most violent tool of oppression used by white supremacists. Nationwide, the share of the population who was black fluctuated between 10 and 13 percent in the years shown here, however the share of lynching victims who were black was almost 73 percent. North-south divide Of the 4.7 thousand victims of lynching between 1882 and 1968, over 3.5 thousand of these were killed in former-Confederate states. Of the fourteen states where the highest number of lynching victims were killed, eleven were former-Confederate states, and all saw the deaths of at least one hundred people due to lynching. Mississippi was the state where most people were lynched in these years, with an estimated 581 victims, 93 percent of whom were black. Georgia saw the second most lynchings, with 531 in total, and the share of black victims was also 93 percent. Compared to the nationwide average of 73 percent, the share of black victims in former-Confederate states was 86 percent. Texas was the only former-Confederate state where this share (71 percent) was below the national average, due to the large number of Mexicans who were lynched there. Outside of the south Of the non-Confederate state with the highest number of lynching victims, most either bordered the former-Confederate states, or were to the west. Generally speaking, the share of white victims in these states was often higher than in the south, meaning that the majority took place in the earlier years represented here; something often attributed to the lack of an established judiciary system in rural regions, and the demand for a speedy resolution. However, there are many reports of black people being lynched in the former border states in the early-20th century, as they made their way northward during the Great Migration. Between 1882 and 1968, lynchings were rare in the Northeast, although Connecticut, Massachusetts, New Hampshire and Rhode Island were the only states** without any recorded lynchings in these years.

From 1966 to January 2024, ** percent of mass public shooters who carried out the shooting at K-12 schools in the United States identified as White, followed by ** percent who were Native American and * percent who were Latinx. For mass public shootings occurring at colleges and universities, the shooter was most likely to identify as Asian, at ** percent, followed by ** percent who were White. In addition, Black and Middle Eastern shooters each made up ** percent. The source defines a mass public shooting as a multiple homicide incident in which 4 or more victims are murdered with firearms—not including the offender(s)—within one event, and at least some of the murders occurred in a public location or locations in close geographical proximity (e.g., a workplace, school, restaurant, or other public settings), and the murders are not attributable to any other underlying criminal activity or commonplace circumstance (armed robbery, criminal competition, insurance fraud, argument, or romantic triangle). Mass shootings attributable to gangs, as well as most domestic homicides, are therefore excluded from this definition.

The term "lynching" is believed to derive from the name of Charles Lynch, a Virginia planter who presided over an irregular and unofficial court during the Revolutionary War. Lynch's use of extralegal measures to punish those loyal to the British crown, helped to inspire mobs in later years to administer their own form of vigilante justice outside of the courts. Eventually, the term came to describe cases where supposed offenders were executed through mob violence without a proper trial and outside of legal jurisdiction. The most famous examples of these executions in the U.S. were those where the victim was hanged (due to the relatively large amount of photographic evidence); however, there were also cases where the victims were shot, burned or tortured and dismembered, among others. Lynching before Jim Crow In the early years of U.S. independence, lynching was most common along the frontier and in western territories, due to the lack of established or immediate judicial systems, and most studies suggest that these victims were mostly white and Mexican. Possibly the largest case of lynching (and largest case of mass hanging) in the United States, was in Texas in 1862, in what is known as the "Great Hanging at Gainsville"; this was where local slaveholders organized the mob hanging of 41 white men and shot three others, due to their supposed allegiance to the Union. Following the American Civil War, however, lynching became inextricably linked with racial inequality and white supremacy in the southern states of the U.S., and black Americans comprised the vast majority of lynching victims from 1886 onwards. Lynching of black Americans The Compromise of 1877 coincided with the emergence of the Jim Crow era in the southern states; it saw the removal of Union troops from the south and established political structures based on white supremacy and the oppression of minorities. Gradually, many of the rights and protections that were granted to black Americans following emancipation were stripped away. This period also saw a vast increase in the number of lynchings in the country, with the majority of these cases taking place in the south. Within ten years of Reconstruction's end, the number of black lynchings exceeded those of white lynchings, and over the next century it is estimated that there were over 4,700 lynchings across the country. Of the 4,740 lynchings estimated to have taken place between 1882 and 1965, 3,445 of the victims were black; this equates to over 72 percent of the total victims of lynching, despite black Americans making up just 10 to 13 percent of the total population. Of these 4,700 lynchings, around 3,500 took place in former Confederate states, where the share of black victims increased to 86 percent. As the years progressed, organized lynchings became more infrequent and were publicized less, and the implementation of the death penalty is thought to have replaced the sense of justice that lynching brought to its perpetrators. Nonetheless, it was not until 1952 where the U.S. went a full year without any known cases of lynching, and the final lynching cases were recorded in 1964 (although some have classified a number of murders after 1964 as lynchings, due to their connections with race and civil rights).

In 2022, there were slightly more female victims of violent crime than male victims in the United States, with about ********* male victims and ********* female victims. These figures are a significant increase from the previous year, when there were ********* male victims and ********* female victims. What counts as violent crime? Violent crime in the United States includes murder, rape, sexual assault, robbery, and assault. While violent crime across all areas has been steadily falling over the past few decades, the rate of aggravated assault is still relatively high, at ***** cases per 100,000 of the population. In 2021, there were more property crimes committed in the U.S. than there were violent crimes. Keep your enemies closer It is usually said that most victims know their attacker, and the data backs this up. In 2021, very few murders were committed by strangers. The same goes for rape and sexual assault victims; the majority were perpetrated by acquaintances, intimate partners, or relatives.

In 2023 in the United States, 12 people were murdered by their employer. However, 3,527 people were killed by an acquaintance compared to 1,674 who were killed by a stranger. A ranking of the total number of murders by U.S. state can be found here.

Between 1982 and September 2024, 82 out of the 151 mass shootings in the United States were carried out by White shooters. By comparison, the perpetrator was African American in 26 mass shootings, and Latino in 12. When calculated as percentages, this amounts to 54 percent, 17 percent, and eight percent respectively. Race of mass shooters reflects the U.S. population Broadly speaking, the racial distribution of mass shootings mirrors the racial distribution of the U.S. population as a whole. While a superficial comparison of the statistics seems to suggest African American shooters are over-represented and Latino shooters underrepresented, the fact that the shooter’s race is unclear in around nine percent of cases, along with the different time frames over which these statistics are calculated, means no such conclusions should be drawn. Conversely, looking at the mass shootings in the United States by gender clearly demonstrates that the majority of mass shootings are carried out by men. Mass shootings and mental health With no clear patterns between the socio-economic or cultural background of mass shooters, increasing attention has been placed on mental health. Analysis of the factors Americans considered to be to blame for mass shootings showed 80 percent of people felt the inability of the mental health system to recognize those who pose a danger to others was a significant factor. This concern is not without merit – in over half of the mass shootings since 1982, the shooter showed prior signs of mental health issues, suggesting improved mental health services may help deal with this horrific problem. Mass shootings and guns In the wake of multiple mass shootings, critics have sought to look beyond the issues of shooter identification and their influences by focusing on their access to guns. The majority of mass shootings in the U.S. involve firearms which were obtained legally, reflecting the easy ability of Americans to purchase and carry deadly weapons in public. Gun control takes on a particular significance when the uniquely American phenomenon of school shootings is considered. The annual number of incidents involving firearms at K-12 schools in the U.S. was over 100 in each year since 2018. Conversely, similar incidents in other developed countries exceptionally rare, with only five school shootings in G7 countries other than the U.S. between 2009 and 2018.

The killing of Tyre Nichols in January 2023 by Memphis Police Officers has reignited debates about police brutality in the United States. Between 2013 and 2024, over 1,000 people have been killed by police every year. Some of the most infamous examples include the murder of George Floyd in May 2020 and the shooting of Breonna Taylor earlier that year. Within the provided time period, the most people killed by police in the United States was in 2024, at 1,375 people. Police Violence in the U.S. Police violence is defined as any instance where a police officer’s use of force results in a civilian’s death, regardless of whether it is considered justified by the law. While many people killed by police in the U.S. were shot, other causes of death have included tasers, vehicles, and physical restraints or beatings. In the United States, the rate of police shootings is much higher for Black Americans than it is for any other ethnicity, and recent incidents of police killing unarmed Black men and women in the United States have led to widespread protests against police brutality, particularly towards communities of color. America’s Persistent Police Problem Despite increasing visibility surrounding police violence in recent years, police killings have continued to occur in the United States at a consistently high rate. In comparison to other countries, police in the U.S. have killed people at a rate three times higher than police in Canada and 60 times the rate of police in England. While U.S. police have killed people in almost all 50 states, as well as the District of Columbia, New Mexico was reported to have the highest rate of people killed by the police in the United States, with 8.03 people per million inhabitants killed by police.

In the United States, more men than women are shot to death by the police. As of October 22, the U.S. police shot 904 men and 44 women to death in 2024. In 2023, the police shot 1,107 men and 48 women to death.
