There is a lack of consensus on how to define a mass shooting. Most terms define a minimum of three or four victims of
gun violence
Gun-related violence is violence committed with the use of a firearm. Gun-related violence may or may not be considered criminal. Criminal violence includes homicide (except when and where ruled justifiable), assault with a deadly weapon, and ...
(not including the shooter or in an inner city) in a short period of time, although an Australian study from 2006 required a minimum of five; and added a requirement that the victims actually died as opposed to being shot and injured but not necessarily killed.
In the United States, the ''Investigative Assistance for Violent Crimes Act of 2012'' defines mass killings as three or more killings in a single incident, however the Act does not define mass shootings. Media outlets such as CNN and some crime violence research groups such as the

s and are not included in mass shooting statistics.
The motive for mass shootings (that occur in public locations) is usually that they are committed by deeply disgruntled individuals who are seeking revenge for failures in school, career, romance, or life in general or who are seeking fame or attention with at least 16 mass shooters since Columbine citing fame or notoriety as a motive.
Fame seekers average more than double the body counts, and many articulated a desire to surpass "past records".
If multiple people are shot in a robbery or killed in a group's terrorist attack, that type of violence is usually not included under the definition of mass shootings.

*Though there are several different definitions of a mass shooting, there are also certain inclusions and exclusions. University of Pennsylvania says no matter how many people are killed, if a shooting occurs by a foreign terrorist that is not included. Another exclusion is if 10 people are shot but only 2 die. Also if 5 people are run over by a car that does not count because no firearm was used. Some inclusions are multiple deaths caused by an armed robbery. Deaths as a result of
gang wars are also sometimes included.
There are also differing definitions of the term mass killing:

The United States has had the most mass shootings of any country.
In a 2016 study published by criminologist Adam Lankford, it was estimated that 31% of all public mass shooters from 1966 to 2012 attacked in the United States, although the U.S. had less than 5% of the world's population. The study concludes that "The United States and other nations with high firearm ownership rates may be particularly susceptible to future public mass shootings, even if they are relatively peaceful or mentally healthy according to other national indicators."

also raised objections to Lankford's methodology and refusal to share his data. He speculated that Lankford had overlooked a significant number of mass shootings outside the US, which if accounted for would adjust the nation's share closer to 2.88%; slightly below the world average. Lankford has since followed up on his research, publishing his data and clarifying that the United States from 1998 to 2012 did in fact have more than six times its global share of public mass shooters who attacked alone, which is almost always the case with mass shooters. Using the data from Lott and Moody's 2019 study of mass shootings, Lankford explains that "41 of all 138 public mass shootings by single perpetrators worldwide were committed in the United States. That represents 29.7%. Because America had in those years approximately 4.5% of the world's population (according to Lott and Moody's calculations), this indicates that based on their own data, the United States had more than six times its global share of public mass shooters who attacked alone (29.7/4.5 = 6.6). In a subsequent study, Lankford criticized Lott and Moody for including "attacks by terrorist organizations, genocidal militias, armed rebel groups, and paramilitary fighters" in their data and suggested they "misrepresent approximately 1,000 foreign cases from their own dataset" in other ways.
Mass shootings have also been observed to be followed by an increase in the purchase of weapons, but does not seem to create an increased feeling of needing guns in either gun owners or non-owners.

Mental health and criminal records
In a study of 55 mass shooters from Mother Jones' mass shooting database, researchers found that 87.5% of perpetrators had misdiagnosed and incorrectly treated or undiagnosed and untreated psychiatric illness.
According to a study by The Violence Project, 42% of all mass shooters experienced physical or sexual abuse, parental suicide, or were victims of bullying. They also found that 72% of perpetrators were suicidal.
In a study of 171 mass shooters who attacked in the United States from 1966 to 2019, researchers Adam Lankford and Rebecca Cowan found that although the vast majority of people with mental illness are not violent, "almost all public mass shooters may have mental health problems." They suggest the frequency of mental health problems among mass shooters is sometimes underestimated because "many perpetrators have never been formally evaluated by a psychiatrist or mental health practitioner...and others deliberately avoid doctors, conceal their mental health problems, or lie about their symptoms due to shame, stigma, or fear of other consequences." However, Lankford and Cowan also emphasize that mental illness is not the sole cause of mass shootings and many other factors play an important role in perpetrators' decisions to attack.
Criminologist James Allen Fox said that most mass murderers do not have a criminal record, or involuntary incarceration at a mental health centre, although an article in ''The New York Times'' in December 2015 about 15 recent mass shootings found that six perpetrators had had run-ins with law enforcement, and six had mental health issues.

who is participating in the construction of a database on mass shooters, noted that two phenomena surface repeatedly in the statistics: hopelessness and a need for notoriety in life or in death.
Notoriety was first suggested as a possible motive and researched by Justin Nutt. Nutt stated in a 2013 article, "those who feel nameless and as though no one will care or remember them when they are gone may feel doing something such as a school shooting will make sure they are remembered and listed in the history books."

, Peterson and Densley found mass shooters had four things in common: (1) early childhood trauma and exposure to violence at a young age; (2) an identifiable grievance or crisis point; (3) validation for their belief system, have studied past shootings to find inspiration; and (4) the means to carry out an attack. This new framework highlights the complexity of the pathway to a mass shooting, including how each one can be "socially contagious," but also provides a blueprint to prevent the next mass shooting. Each one of the four themes represents an opportunity for intervention. By reducing access to firearms (means), slowing contagion (validation), training in crisis intervention de-escalation (crisis), and increasing access to affordable mental healthcare (trauma), a mass shooting can be averted.
In considering the frequency of mass shootings in the United States, criminologist Peter Squires says that the individualistic culture in the United States puts the country at greater risk for mass shootings than other countries, noting that "many other countries where gun ownership is high, such as Norway, Finland, Switzerland and Israel . . . tend to have more tight-knit societies where a strong social bond supports people through crises, and mass killings are fewer."

Social science and family structure

Moynihan said that "almost all school shooters come from families where the parents are either divorced or alienated," and Cook argued that "perhaps they wouldn't need more gun control if they had better divorce control."
Responses
Media
Some people have considered whether media attention revolving around the perpetrators of mass shootings is a factor in sparking further incidents. In response to this, some in law enforcement have decided against naming mass shooting suspects in media-related events to avoid giving them notoriety.

, support for gun law reform varies considerably by political party, with Democrats generally more supportive and Republicans generally more opposed. Some in the U.S. believe that tightening gun laws would prevent future mass shootings. Some politicians in the U.S. introduced legislation to reform the background check system for purchasing a gun. A vast majority of Americans support tighter background checks. "According to a poll by Quinnipiac University in Connecticut, 93 percent of registered voters said they would support universal background checks for all gun buyers."
Others contend that mass shootings should not be the main focus in the gun law reform debate because these shootings account for less than one percent of the U.S. homicide rate and believe that these shootings are hard to stop. They often argue that civilians with concealed guns will be able to stop shootings.
According to British criminologist Peter Squires, who has studied gun violence in different countries, mass shootings may be more due to the "individualistic culture" in the U.S. than its firearm laws.
