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.

Victims of gang-related homicides (total number of homicide victims; number of homicide victims - unknown gang-relation; number of homicide victims - known gang relation; number of gang-related homicide victims; percentage of gang-related homicide victims; rate (per 100,000 population) of gang-related homicide victims), Canada and regions, 1999 to 2024.

In 2024, there were 301,623 cases filed by the National Crime Information Center (NCIC) where the race of the reported missing person was white. In the same year, 17,097 people whose race was unknown were also reported missing in the United States. What is the NCIC? The National Crime Information Center (NCIC) is a digital database that stores crime data for the United States, so criminal justice agencies can access it. As a part of the FBI, it helps criminal justice professionals find criminals, missing people, stolen property, and terrorists. The NCIC database is broken down into 21 files. Seven files belong to stolen property and items, and 14 belong to persons, including the National Sex Offender Register, Missing Person, and Identify Theft. It works alongside federal, tribal, state, and local agencies. The NCIC’s goal is to maintain a centralized information system between local branches and offices, so information is easily accessible nationwide. Missing people in the United States A person is considered missing when they have disappeared and their location is unknown. A person who is considered missing might have left voluntarily, but that is not always the case. The number of the NCIC unidentified person files in the United States has fluctuated since 1990, and in 2022, there were slightly more NCIC missing person files for males as compared to females. Fortunately, the number of NCIC missing person files has been mostly decreasing since 1998.

Observera att detta dataset uppdateras varje månad i början av månaden. Data körs fram till slutet av månaden innan.

Metropolitan Police Service (MPS) har infört & nbsp;CONNECT, ett nytt brottsregistreringssystem som konsoliderar flera tidigare system till en integrerad plattform. Denna förändring syftar till att effektivisera processer och öka effektiviteten över hela linjen.

Med genomförandet av CONNECT har det gjorts smärre ändringar i registreringen av specifika brottskategorier, såsom hatbrott. Dessa justeringar kan leda till mindre variationer i brottsdata jämfört med tiden före CONNECT. För att ge en heltäckande bild av data har MPS regenererat hela rapporten för att täcka hela tidsperioden.

BCU- och Borough-data i CONNECT bestäms av incidentens geografiska läge, snarare än den stadsdel som hanterar ärendet, vilket var fallet med äldre system. Denna nya metod har tillämpats retroaktivt på äldre uppgifter för att ge en konsekvent och jämförbar analys.

Business Crime definieras av National Business Crime Forum (NBCF), inrikesministeriet och National Retail Crime Steering Group (NRCSG), som leds av ministern för brottsförebyggande som:

Ansatsen återspeglar de befintliga definitionerna av våld i hemmet och hatbrott. Det innebär att brottsoffret avgör om brottet har påverkat ett företag eller inte och därmed om det ska identifieras som ett affärsbrott. Detta undanröjer all tvetydighet om hur brottet ska registreras.

Inte alla affärsbrott kommer omedelbart att identifieras som sådana av offret eller andra. Till exempel kan ett övergrepp på en nattklubb inte identifieras som ett affärsbrott av offret eftersom de är mer benägna att uppfatta det som en personlig attack, t.ex. motiverad av våld i hemmet eller hatrelaterad fientlighet.

Oavsett brottets art, om brottet ägde rum i affärslokaler bör det dessutom registreras som ett affärsbrott. Detta beror på att alla typer av brott i affärslokaler kan ha en negativ inverkan på verksamheten, t.ex. höjda försäkringspremier eller, som i fallet med nattklubbsövergreppet, negativ inverkan på huruvida nattklubbens licens förnyas (t.ex. att alltför många överfall har ägt rum på den platsen).
