Age of onset (or onset age) is a term that is used in criminology in reference to the age at which the offense of a crime is first committed by a specific person. [1] [2] [3]
Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as "antisocial behaviors", and is often seen as the precursor to antisocial personality disorder; however, the latter, by definition, cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. Conduct disorder is estimated to affect 51.1 million people globally as of 2013.
Hebephilia is the strong, persistent sexual interest by adults in pubescent children who are in early adolescence, typically ages 11–14 and showing Tanner stages 2 to 3 of physical development. It differs from pedophilia, and from ephebophilia. While individuals with a sexual preference for adults may have some sexual interest in pubescent-aged individuals, researchers and clinical diagnoses have proposed that hebephilia is characterized by a sexual preference for pubescent rather than adult partners.
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. These acts would otherwise be considered crimes if the individuals committing them were older. The term delinquent usually refers to juvenile delinquency, and is also generalised to refer to a young person who behaves an unacceptable way.
Crime science is the study of crime in order to find ways to prevent it. It is distinguished from criminology in that it is focused on how crime is committed and how to reduce it, rather than on who committed it. It is multidisciplinary, notably recruiting scientific methodology rather than relying on social theory.
In the United States, the relationship between race and crime has been a topic of public controversy and scholarly debate for more than a century. Crime rates vary significantly between racial groups; however, academic research indicates that the over-representation of some racial minorities in the criminal justice system can in part be explained by socioeconomic factors, such as poverty, exposure to poor neighborhoods, poor access to public and early education, and exposure to harmful chemicals and pollution. Racial housing segregation has also been linked to racial disparities in crime rates, as black Americans have historically and to the present been prevented from moving into prosperous low-crime areas through actions of the government and private actors. Various explanations within criminology have been proposed for racial disparities in crime rates, including conflict theory, strain theory, general strain theory, social disorganization theory, macrostructural opportunity theory, social control theory, and subcultural theory.
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. The nature or motive of the crime itself may also require consideration as a factor. Gendered profiling might affect the reported crime rates.
Pedophilia is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children. Although girls typically begin the process of puberty at age 10 or 11, and boys at age 11 or 12, psychiatric diagnostic criteria for pedophilia extend the cut-off point for prepubescence to age 13. People with the disorder are often referred to as pedophiles.

Robert Agnew is the Samuel Candler Dobbs Professor of Sociology at Emory University and past president of the American Society of Criminology.
The self-control theory of crime, often referred to as the general theory of crime, is a criminological theory about the lack of individual self-control as the main factor behind criminal behavior. The self-control theory of crime suggests that individuals who were ineffectually parented before the age of ten develop less self-control than individuals of approximately the same age who were raised with better parenting. Research has also found that low levels of self-control are correlated with criminal and impulsive conduct.
The correlates of crime explore the associations of specific non-criminal factors with specific crimes.
General strain theory (GST) is a theory of criminology developed by Robert Agnew. General strain theory has gained a significant amount of academic attention since being developed in 1992. Robert Agnew's general strain theory is considered to be a solid theory, has accumulated a significant amount of empirical evidence, and has also expanded its primary scope by offering explanations of phenomena outside of criminal behavior. This theory is presented as a micro-level theory because it focuses more on a single person at a time rather than looking at the whole of society.
In 1993, American psychologist Terrie Moffitt described a dual taxonomy of offending behavior in an attempt to explain the developmental processes that lead to the distinctive shape of the age crime curve. Moffitt proposed that there are two main types of antisocial offenders in society: The adolescence-limited offenders, who exhibit antisocial behavior only during adolescence, and the life-course-persistent offenders, who begin to behave antisocially early in childhood and continue this behavior into adulthood. This theory is used with respect to antisocial behavior instead of crime due to the differing definitions of 'crime' among cultures. Due to similar characteristics and trajectories, this theory can be applied to both females and males.
Criminology is the interdisciplinary study of crime and deviant behaviour. Criminology is a multidisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, legal sociologists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, scholars of law and jurisprudence, as well as the processes that define administration of justice and the criminal justice system.
Terrie Edith Moffitt is an American-British clinical psychologist who is best known for her pioneering research on the development of antisocial behavior and for her collaboration with colleague and partner Avshalom Caspi in research on gene-environment interactions in mental disorders.
In criminology, Mobility triangles are the triangular areas formed by the locations of the victim's home, the offender's home and the crime. They are used to describe spatial patterns of crimes, and to facilitate the classification of crimes based on location. Implicit in the concept is the assumption that the homes of the victim and the offender form anchor points that govern the crime location. Mobility triangles are related to the criminological frameworks of routine activity theory and environmental criminology.
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.
David Philip Farrington is a British criminologist, forensic psychologist, and emeritus professor of psychological criminology at the University of Cambridge, where he is also a Leverhulme Trust Emeritus Fellow. In 2014, Paul Hawkins and Bitna Kim wrote that Farrington "is considered one of the leading psychologists and main contributors to the field of criminology in recent years."
Legal cynicism is a domain of legal socialization defined by a perception that the legal system and law enforcement agents are "illegitimate, unresponsive, and ill equipped to ensure public safety." It is related to police legitimacy, and the two serve as important ways for researchers to study citizens' perceptions of law enforcement.
