Victimology is the study of victimization, including the psychological effects on victims, the relationship between victims and offenders, the interactions between victims and the criminal justice system—that is, the police and courts, and corrections officials—and the connections between victims and other social groups and institutions, such as the media, businesses, and social movements.
A serial killer is typically a person who murders three or more persons, with the murders taking place over more than a month and including a significant period of time between them. While most authorities set a threshold of three murders, others extend it to four or lessen it to two.
Juvenile delinquency, also known as juvenile offending, is the act of participating in unlawful behavior as a minor or individual younger than the statutory age of majority. In the United States of America, a juvenile delinquent is a person who commits a crime and is under a specific age. Most states specify a juvenile delinquent, or young offender, as an individual under 18 years of age while a few states have set the maximum age slightly different. In 2021, Michigan, New York, and Vermont raised the maximum age to under 19, and Vermont law was updated again in 2022 to include individuals under the age of 20. Only three states, Georgia, Texas, and Wisconsin still appropriate the age of a juvenile delinquent as someone under the age of 17. While the maximum age in some US states has increased, Japan has lowered the juvenile delinquent age from under 20 to under 18. This change occurred on April 1, 2022 when the Japanese Diet activated a law lowering the age of minor status in the country. Just as there are differences in the maximum age of a juvenile delinquent, the minimum age for a child to be considered capable of delinquency or the age of criminal responsibility varies considerably between the states. Some states that impose a minimum age have made recent amendments to raise the minimum age, but most states remain ambiguous on the minimum age for a child to be determined a juvenile delinquent. In 2021, North Carolina changed the minimum age from 6 years old to 10 years old while Connecticut moved from 7 to 10 and New York made an adjustment from 7 to 12. In some states the minimum age depends on the seriousness of the crime committed. Juvenile delinquents or juvenile offenders commit crimes ranging from status offenses such as, truancy, violating a curfew or underage drinking and smoking to more serious offenses categorized as property crimes, violent crimes, sexual offenses, and cybercrimes.
Lust murder, also called sexual homicide, is a homicide which occurs in tandem with either an overt sexual assault or sexually symbolic behavior. Lust murder is associated with the paraphilic term erotophonophilia, which is sexual arousal or gratification contingent on the death of a human being. The term lust killing stems from the original work of Richard von Krafft-Ebing in his 1898 discussion of sadistic homicides. Commonly, this type of crime is manifested either by murder during sexual activity, by mutilating the sexual organs or areas of the victim's body, or by murder and mutilation. The mutilation of the victim may include evisceration, displacement of the sexual organs, or both. The mutilation usually takes place postmortem. Although the killing sequence may include an act of sexual intercourse, sexual intercourse does not always occur, and other types of sexual acts may be part of the homicide.
Geographic profiling is a criminal investigative methodology that analyzes the locations of a connected series of crimes to determine the most probable area of offender residence. By incorporating both qualitative and quantitative methods, it assists in understanding spatial behaviour of an offender and focusing the investigation to a smaller area of the community. Typically used in cases of serial murder or rape, the technique helps police detectives prioritize information in large-scale major crime investigations that often involve hundreds or thousands of suspects and tips.
Victim blaming occurs when the victim of a crime or any wrongful act is held entirely or partially at fault for the harm that befell them. There is historical and current prejudice against the victims of domestic violence and sex crimes, such as the greater tendency to blame victims of rape than victims of robbery if victims and perpetrators knew each other prior to the commission of the crime.

In criminology, a disorganized offender is a type of serial killer classified by unorganized and spontaneous acts of violence. The distinction between "organized" and "disorganized" offenders was drawn by the American criminologist Roy Hazelwood. These profiles were also studied and modified in the FBI's Behavioral Science Unit located in Quantico, Virginia. By classifying these offenders into different categories, the FBI is able to track down offenders by studying their behavior and habits. One well-known example of a disorganized offender is Jack the Ripper.
Sex differences in crime are differences between men and women as the perpetrators or victims of crime. Such studies may belong to fields such as criminology, sociobiology, or feminist studies. Despite the difficulty of interpreting them, crime statistics may provide a way to investigate such a relationship from a gender differences perspective. An observable difference in crime rates between men and women might be due to social and cultural factors, crimes going unreported, or to biological factors for example, testosterone or sociobiological theories). The nature of the crime itself may also require consideration as a factor.
Some jurisdictions may commit certain types of dangerous sex offenders to state-run detention facilities following the completion of their sentence if that person has a "mental abnormality" or personality disorder that makes the person likely to engage in sexual offenses if not confined in a secure facility. In the United States, twenty states, the federal government, and the District of Columbia have a version of these commitment laws, which are referred to as "Sexually Violent Predator" (SVP) or "Sexually Dangerous Persons" laws.
A sex offender is a person who has committed a sex crime. What constitutes a sex crime differs by culture and legal jurisdiction. The majority of convicted sex offenders have convictions for crimes of a sexual nature; however, some sex offenders have simply violated a law contained in a sexual category. Some of the serious crimes which usually result in a mandatory sex-offender classification are sexual assault, statutory rape, bestiality, child sexual abuse, incest, rape, and sexual imposition.
In criminology, rational choice theory adopts a utilitarian belief that humans are reasoning actors who weigh means and ends, costs and benefits, in order to make a rational choice. This method was designed by Cornish and Clarke to assist in thinking about situational crime prevention.
Rape can be categorized in different ways: for example, by reference to the situation in which it occurs, by the identity or characteristics of the victim, and by the identity or characteristics of the perpetrator. These categories are referred to as types of rape. The types described below are not mutually exclusive: a given rape can fit into multiple categories, by for example being both a prison rape and a gang rape, or both a custodial rape and the rape of a child.
Serial crimes are crimes of a repetitive nature. Serial murder, serial rape and serial arson are crimes regarded as serial crimes. However, according to criminologists, a habitual offender or a career criminal is not necessarily a serial criminal.
The FBI method of profiling is a system created by the Federal Bureau of Investigation (FBI) used to detect and classify the major personality and behavioral characteristics of an individual based upon analysis of the crime or crimes the person committed. One of the first American profilers was FBI agent John E. Douglas, who was also instrumental in developing the behavioral science method of law enforcement.
Routine activity theory is a sub-field of crime opportunity theory that focuses on situations of crimes. It was first proposed by Marcus Felson and Lawrence E. Cohen in their explanation of crime rate changes in the United States between 1947 and 1974. The theory has been extensively applied and has become one of the most cited theories in criminology. Unlike criminological theories of criminality, routine activity theory studies crime as an event, closely relates crime to its environment and emphasizes its ecological process, thereby diverting academic attention away from mere offenders.
The Macdonald triad is a set of three factors, the presence of any two of which are considered to be predictive of, or associated with, violent tendencies, particularly with relation to serial offenses. The triad was first proposed by psychiatrist J. M. Macdonald in "The Threat to Kill", a 1963 article in the American Journal of Psychiatry. Small-scale studies conducted by psychiatrists Daniel Hellman and Nathan Blackman, and then FBI agents John E. Douglas and Robert K. Ressler along with Ann Burgess, claimed substantial evidence for the association of these childhood patterns with later predatory behavior. Although it remains an influential and widely taught hypothesis, subsequent research has generally not validated this line of thinking.
A serial rapist is someone who commits multiple rapes, whether with multiple victims or a single victim repeatedly over a period of time. Some serial rapists target children. The terms sexual predator, repeat rape and multiple offending can also be used to describe the activities of those who commit a number of consecutive rapes, but remain unprosecuted when self-reported in research. Others will commit their assaults in prisons. In some instances, a group of serial rapists will work together. These rapists can have a pattern of behavior that is sometimes used to predict their activities and aid in their arrest and conviction. Serial rapists also differ from one time offenders because "serial rapists more often involved kidnapping, verbally and physically threatening the victims, and using or threatening the use of weapons."
Crime opportunity theory suggests that offenders make rational choices and thus choose targets that offer a high reward with little effort and risk. The occurrence of a crime depends on two things: the presence of at least one motivated offender who is ready and willing to engage in a crime, and the conditions of the environment in which that offender is situated, to wit, opportunities for crime. All crimes require opportunity but not every opportunity is followed by crime. Similarly, a motivated offender is necessary for the commission of a crime but not sufficient. A large part of this theory focuses on how variations in lifestyle or routine activities affect the opportunities for crime.
The feminist pathways perspective is a feminist perspective of criminology which suggests victimization throughout the life course is a key risk factor for women's entry into offending.
