Violence is often defined as the use of physical force to cause harm to people, or non-human life, such as pain, injury, death, damage, or destruction, but some definitions are somewhat broader, such as the World Health Organization's definition, as "the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation."
A school shooting is an armed attack at an educational institution, such as a primary school, secondary school, high school or university, involving the use of a firearm. Many school shootings are also categorized as mass shootings due to multiple casualties. The phenomenon is most widespread in the United States, which has the highest number of school-related shootings, although school shootings take place elsewhere in the world. Especially in the United States, school shootings have sparked a political debate over gun violence, zero tolerance policies, gun rights and gun control.
A violent crime, violent felony, crime of violence or crime of a violent nature is a crime in which an offender or perpetrator uses or threatens to use harmful force upon a victim. This entails both crimes in which the violent act is the objective, such as murder, assault, rape and assassination, as well as crimes in which violence is used as a method of coercion or show of force, such as robbery, extortion and terrorism. Violent crimes may, or may not, be committed with weapons. Depending on the jurisdiction, violent crimes may be regarded with varying severities from homicide to harassment.
Psychological abuse, often known as emotional abuse or mental abuse or psychological violence, is a form of abuse characterized by a person subjecting or exposing another person to a behavior that may result in psychological trauma, including anxiety, chronic depression, clinical depression or post-traumatic stress disorder amongst other psychological problems.
School violence includes violence between school students as well as attacks by students on school staff and attacks by school staff on students. It encompasses physical violence, including student-on-student fighting, corporal punishment; psychological violence such as verbal abuse, and sexual violence, including rape and sexual harassment. It includes many forms of bullying and carrying weapons to school. The one or more perpetrators typically have more physical, social, and/or psychological power than the victim. It is a widely accepted serious societal problem in recent decades in many countries, especially where weapons such as guns or knives are involved.
Rape by gender classifies types of rape by the sex and gender of both the rapist and the victim. This scope includes both rape and sexual assault more generally. Most research indicates that rape affects women disproportionately, with the majority of people convicted being men; however, since the broadening of the definition of rape in 2012 by the FBI, more attention is being given to male rape, including females raping males.
Statistics on rape and other acts of sexual assault are commonly available in industrialized countries, and have become better documented throughout the world. Inconsistent definitions of rape, different rates of reporting, recording, prosecution and conviction for rape can create controversial statistical disparities, and lead to accusations that many rape statistics are unreliable or misleading.
Intimate partner violence (IPV) is domestic violence by a current or former spouse or partner in an intimate relationship against the other spouse or partner. IPV can take a number of forms, including physical, verbal, emotional, economic and sexual abuse. The World Health Organization (WHO) defines IPV as "any behavior within an intimate relationship that causes physical, psychological or sexual harm to those in the relationship, including acts of physical aggression, sexual coercion, psychological abuse and controlling behaviors." IPV is sometimes referred to simply as battery, or as spouse or partner abuse.
Domestic violence occurs across the world, in various cultures, and affects people across society, at all levels of economic status; however, indicators of lower socioeconomic status have been shown to be risk factors for higher levels of domestic violence in several studies. In the United States, according to the Bureau of Justice Statistics in 1995, women reported a six times greater rate of intimate partner violence than men. However, studies have found that men are much less likely to report victimization in these situations.
Teen dating violence is the physical, sexual, or psychological / emotional abuse within a dating relationship among adolescents. Intimate partner violence (IPV) has been a well examined and documented phenomenon in adults; however, there has not been nearly as much study on violence in adolescent dating relationships, and it is therefore not as well understood. The research has mainly focused on Caucasian youth, and, as of 2013, there are no studies which focus specifically on IPV in adolescent same-sex relationships.
School bullying, like bullying outside the school context, refers to one or more perpetrators who have greater physical strength or more social power than their victim and who repeatedly act aggressively toward their victim. Bullying can be verbal or physical. Bullying, with its ongoing character, is distinct from one-off types of peer conflict. Different types of school bullying include ongoing physical, emotional, and/or verbal aggression. Cyberbullying and sexual bullying are also types of bullying. Bullying even exists in higher education. There are warning signs that suggest that a child is being bullied, a child is acting as a bully, or a child has witnessed bullying at school.
Estimates of sexual violence are surveys of victims of sexual violence crime that have been undertaken to estimate the prevalence of sexual violence. The prevalence of sexual violence differs from the reported sexual violence statistics according to the law enforcement agencies due to the dark figure of crime. The surveys use a common methodology to aid comparability.
Victimisation is the state or process of being victimised or becoming a victim. The field that studies the process, rates, incidence, effects, and prevalence of victimisation is called victimology.
Crime statistics in the United Kingdom refers to the data collected in the United Kingdom, and that collected by the individual areas, England and Wales, Scotland and Northern Ireland, which operate separate judicial systems. It covers data related to crime in the United Kingdom. As with crime statistics elsewhere, they are broadly divided into victim studies and police statistics. More recently, third-party reporting is used to quantify specific under-reported issues, for example, hate crime.
Campus sexual assault is the sexual assault, including rape, of a student while attending an institution of higher learning, such as a college or university. The victims of such assaults are more likely to be female, but any gender can be victimized. Estimates of sexual assault, which vary based on definitions and methodology, generally find that somewhere between 19–27% of college women and 6–8% of college men are sexually assaulted during their time in college.
Domestic violence against men is violence or other physical abuse towards men in a domestic setting, such as in marriage or cohabitation. As with domestic violence against women, violence against men may constitute a crime, but laws vary between jurisdictions. Intimate partner violence (IPV) against men is generally less recognized by society than intimate partner violence against women, which can act as a further block to men reporting their situation or otherwise seeking help.
Violence against men comprises violent acts that are disproportionately committed against men or boys. Men are overrepresented as both victims and perpetrators of violence. Violence against women is the opposite category, where acts of violence are targeted against the female gender.
Since their inception in the 1970s, video games have often been criticized by some for violent content. Politicians, parents, and other activists have claimed that violence in video games can be tied to violent behavior, particularly in children, and have sought ways to regulate the sale of video games. Studies have shown no connection between video games and violent behavior. The American Psychological Association states that while there is a well-established link between violent video games and aggressive behaviors, attributing acts of violence to violent video gaming "is not scientifically sound."
According to the U.S. National Center for Education Statistics, school violence is a serious problem. In 2007, the latest year for which comprehensive data were available, a nationwide survey, conducted biennially by the Centers for Disease Control and Prevention (CDC) and involving representative samples of U.S. high school students, found that 5.9% of students carried a weapon on school property during the 30 days antedating the survey. The rate was three times higher among men than among women. In the twelve months preceding the survey, 7.8% of high school students reported having been threatened or injured with a weapon on school property at least once, with the prevalence rate among male students twice that as among female students. In the twelve months preceding the survey, 12.4% of students had been in a physical fight on school property at least once. The rate among males was twice the rate found among females. In the thirty days preceding the survey, 5.5% of students reported that because they did not feel safe, they did not go to school on at least one day. The rates for males and females were approximately equal.
Arming teachers is equipping teachers in preschool through secondary school with firearms with the intent to prevent casualties from school shootings. Such proposals have engendered public debate regarding with whom the responsibility for providing a safe environment lies, and whether it would reduce or escalate the risk of shootings. School shootings, and proposals to arm teachers, are most common in the United States, but proposals have also been made in countries such as Israel, Kenya, Pakistan, South Africa, and Thailand.
