statutory definitions have been provided for certain purposes. The most popular view is that crime is a
category created by
law; in other words, something is a crime if declared as such by the relevant and applicable law.
One proposed definition is that a crime or offence (or criminal offence) is an act harmful not only to some individual but also to a community, society, or the state ("a public
wrong"). Such acts are forbidden and punishable by law.
The notion that acts such as
murder,
rape, and
theft are to be prohibited exists worldwide.

Definition
The exact definition of crime is a philosophical issue without an agreed upon answer. Fields such as law, politics, sociology, and psychology define crime in different ways. Crimes may be variously considered as wrongs against individuals, against the community, or against the state. The criminality of an action is dependent on its context; acts of violence will be seen as crimes in many circumstances but as permissible or desirable in others. Crime was historically seen as a manifestation of

liberal democratic societies that prioritize
individualism and
multiculturalism over other moral beliefs.
Paternalism defines crime not only as harm to others or to society, but also as harm to the self.
Psychology

History
Early history
Restrictions on behavior existed in all prehistoric societies. Crime in early human society was seen as a personal transgression and was addressed by the community as a whole rather than through a formal legal system, often through the use of custom, religion, or the rule of a tribal leader. Some of the oldest extant writings are ancient
criminal codes. The earliest known criminal code was the
Code of Ur-Nammu (),
and the first known criminal code that incorporated retaliatory justice was the
Code of Hammurabi. The latter influenced the conception of crime across several civilizations over the following millennia.
The

regarded assaults as a matter of private compensation. The most significant Roman law concept involved ''dominion''. Most acts recognized as crimes in ancient societies, such as violence and theft, have persisted to the modern era. The criminal justice system of Imperial China existed unbroken for over 2,000 years.
Many of the earliest conceptions of crime are associated with
sin and corresponded to acts that were believed to invoke the anger of a deity. This idea was further popularized with the development of the
Abrahamic religions

Modern era
In the modern era, crime came to be seen as an issue affecting society rather than conflicts between individuals. Writers such as
Thomas Hobbes
Thomas Hobbes ( ; 5 April 1588 – 4 December 1679) was an English philosopher, best known for his 1651 book ''Leviathan (Hobbes book), Leviathan'', in which he expounds an influential formulation of social contract theory. He is considered t ...

industrialization in the 19th century caused crime to become an immediate issue that affected society, prompting government intervention in crime and the establishment of criminology as its own field.

Cesare Lombroso in the late-19th century. This was a
biological determinist school of thought based in
social darwinism, arguing that certain people are naturally born as criminals. The

Law enforcement
The enforcement of criminal law seeks to prevent crime and sanction crimes that do occur. This enforcement is carried out by the state through
law enforcement agencies, such as
police

, which are empowered to
arrest suspected perpetrators of crimes. Law enforcement may focus on policing individual crimes, or it may focus on bringing down overall crime rates. One common variant,
community policing, seeks to prevent crime by integrating police into the community and public life.
Criminal procedure
When the perpetrator of a crime is found guilty of the crime, the state delivers a
sentence to determine the penalty for the crime.
Liability
If a crime is committed, the individual responsible is considered to be liable for the crime. For liability to exist, the individual must be capable of understanding the criminal process and the relevant authority must have legitimate power to establish what constitutes a crime.
International criminal law

tribunals to investigate and rule on egregious offenses such as genocide.

political agenda of a given state, and they are necessarily applied against political
dissidents. Due to their unique relation to the state, political crimes are often encouraged by one nation against another, and it is political alignment rather than the act itself that determines criminality.
State crime that is carried out by the state to
repress law-abiding citizens may also be considered political crime.
Inchoate crime
Inchoate crime is crime that is carried out in anticipation of other illegal actions but does not cause direct harm. Examples of inchoate crimes include
attempt and
conspiracy. Inchoate crimes are defined by substantial action to facilitate a crime with the intention of the crime's occurrence. This is distinct from simple preparation for or consideration of criminal activity. They are unique in that
renunciation of criminal intention is generally enough to absolve the perpetrator of criminal liability, as their actions are no longer facilitating a potential future crime.
Participants
Criminal
A criminal is an individual who commits a crime. What constitutes a criminal can vary depending on the context and the law, and it often carries a pejorative connotation. Criminals are often seen as embodying certain stereotypes or traits and are seen as a distinct type of person from law-abiding citizens. Despite this, no mental or physical trend is identifiable that differentiates criminals from non-criminals. Public response to criminals may be indignant or sympathetic. Indignant responses involve resentment and a desire for vengeance, wishing to see criminals removed from society or made to suffer for harm that they cause. Sympathetic responses involve compassion and understanding, seeking to rehabilitate or forgive criminals and absolve them of blame.

s were capable of committing crimes, and prosecuted and punished them accordingly.
Prosecutions of animals gradually dwindled during the 19th century, although a few were recorded as late as the 1910s and 1920s.
Victim
A victim is an individual who has been treated unjustly or made to suffer. In the context of crime, the victim is the individual that is harmed by a violation of criminal law. Victimization is associated with
post-traumatic stress and a long-term decrease in
quality of life.
Victimology is the study of victims, including their role in crime and how they are affected.
Several factors affect an individual's likelihood of becoming a victim. Some factors may cause victims of crime to experience short-term or long-term "repeat victimization". Common long-term victims are those that have close relationships with the criminal, manifesting in crimes such as
domestic violence,
embezzlement,
child abuse, and
bullying
Bullying is the use of force, coercion, Suffering, hurtful teasing, comments, or threats, in order to abuse, aggression, aggressively wikt:domination, dominate, or intimidate one or more others. The behavior is often repeated and habitual. On ...
. Repeat victimization may also occur when a potential victim appears to be a viable target, such as when indicating wealth in a less affluent region. Many of the traits that indicate criminality also indicate victimality; victims of crime are more likely to engage in unlawful behavior and respond to provocation. Overall demographic trends of victims and criminals are often similar, and victims are more likely to have engaged in criminal activities themselves.
The victims may only want compensation for the injuries suffered, while remaining indifferent to a possible desire for
deterrence. Victims, on their own, may lack the economies of scale that could allow them to administer a penal system, let alone to collect any fines levied by a court.
Crime statistics
Information and statistics about crime in a given jurisdiction are collected as crime estimates, typically produced by national or international agencies. Methods to collect
crime statistics may vary, even between jurisdictions within the same nation.
Under-reporting of crime is common, particularly in developing nations, resulting in the
dark figure of crime.
Victim studies may be used to determine the frequency of crime in a given population.
The gap to official statistics is generally smaller with higher
severity of the crime.
Clearance rate measures the fraction of crimes where a
criminal charge has been laid or the responsible person
convicted.

. Exposure of crime through news stories is associated with
alarmism and inaccurate perceptions of crime trends.
Selection bias in new stories about criminals significantly over-represent the prevalence of violent crime, and news reporting will often overemphasize a specific type of crime for a period of time, creating a "crime wave" effect.
As public opinion of morality changes over time, actions that were once condemned as crimes may be considered justifiable.

Thomas Aquinas ( ; ; – 7 March 1274) was an Italian Dominican Order, Dominican friar and Catholic priest, priest, the foremost Scholasticism, Scholastic thinker, as well as one of the most influential philosophers and theologians in the W ...
wrote in the 13th century: "the rule and measure of human acts is the
reason, which is the first principle of human acts". He regarded people as by nature
rational beings, concluding that it becomes morally appropriate that they should behave in a way that conforms to their rational nature. Thus, to be valid, any law must conform to natural law and coercing people to conform to that law is morally acceptable. In the 1760s,
William Blackstone described the thesis:
: "This law of nature, being co-eval with mankind and dictated by God himself, is of course superior in obligation to any other. It is binding over all the globe, in all countries, and at all times: no human laws are of any validity, if contrary to this; and such of them as are valid derive all their force, and all their authority, mediately or immediately, from this original."
But
John Austin (1790–1859), an early
positivist, applied
utilitarianism in accepting the calculating nature of human beings and the existence of an objective morality. He denied that the legal validity of a norm depends on whether its content conforms to morality. Thus, in Austinian terms, a moral code can objectively determine what people ought to do, the law can embody whatever norms the legislature decrees to achieve social utility, but every individual remains free to choose what to do. Similarly,
H.L.A. Hart saw the law as an aspect of
sovereignty, with lawmakers able to adopt any law as a means to a moral end.
Thus the necessary and sufficient conditions for the truth of a proposition of law involved internal

and
consistency, and that the state's agents used state power with
responsibility.
Ronald Dworkin rejects Hart's theory and proposes that all individuals should expect the equal respect and concern of those who govern them as a fundamental political right. He offers a theory of compliance overlaid by a theory of
deference (the citizen's duty to obey the law) and a theory of enforcement, which identifies the legitimate goals of enforcement and punishment. Legislation must conform to a theory of legitimacy, which describes the circumstances under which a particular person or group is entitled to make law, and a theory of legislative justice, which describes the law they are entitled or obliged to make.
There are natural-law theorists who have accepted the idea of enforcing the prevailing morality as a primary function of the law. This view entails the problem that it makes any moral criticism of the law impossible: if conformity with natural law forms a necessary condition for legal validity, all valid law must, by definition, count as morally just. Thus, on this line of reasoning, the legal validity of a norm necessarily entails its moral justice.
Corrections and punishment
Authorities may respond to crime through corrections, carrying out punishment as a means to
censure the criminal act. Punishment is generally reserved for serious offenses. Individuals regularly engage in activity that could be scrutinized under criminal law but are deemed inconsequential.
Retributive justice seeks to create a system of
accountability
In ethics and governance, accountability is equated with answerability, culpability, liability, and the expectation of account-giving.

and punish criminals in a way that knowingly causes suffering. This may arise out of a feeling that criminals deserve to suffer and that punishment should exist for its own sake. The existence of punishment also creates an effect of
deterrence that discourages criminal action for fear of punishment.
Rehabilitation seeks to understand and mitigate the causes of a criminal's unlawful action to prevent
recidivism. Different criminological theories propose different methods of rehabilitation, including strengthening
social networks, reducing

Whether a crime can be resolved through financial compensation varies depending on the culture and the specific context of the crime. Historically, many societies have absolved acts of homicide through compensation to the victim's relatives.
Criminology
The study of crime is called ''criminology''. Criminology is a subfield of
sociology
Sociology is the scientific study of human society that focuses on society, human social behavior, patterns of Interpersonal ties, social relationships, social interaction, and aspects of culture associated with everyday life. The term sociol ...

violence. It includes the
motivations and
consequences of crime and its
perpetrators, as well as
preventative measures, either studying criminal acts on an individual level or the relationship of crime and the community.
Due to the wide range of concepts associated with crime and the disagreement on a precise definition, the focus of criminology can vary considerably. Various theories within criminology provide different descriptions and explanations for crime, including
social control theory,
subcultural theory,
strain theory,
differential association, and
labeling theory.
Subfields of criminology and related fields of study include

Causes and correlates
Criminal behavior determinants include
cost–benefit analysis,
opportunity or
crime of passion.
A person that commits a criminal act typically believes that its benefits will outweigh the risk of being caught and punished. Negative economic factors, such as
unemployment and
income inequality, can increase the incentive to commit crime, while severe punishments can
deter crime in some cases.
Social factors similarly affect the likelihood of criminal activity.
Crime corresponds heavily with
social integration; groups that are less integrated with society or that are forcibly integrated with society are more likely to engage in crime. Involvement in the community, such as through a church, decreases the likelihood of crime, while associating with criminals increases the likelihood of becoming a criminal as well.
There is no known
genetic cause of crime. Some genes have been found to affect traits that may incline individuals toward criminal activity, but no biological or physiological trait has been found to directly cause or compel criminal actions. One biological factor is the
disparity between men and women, as men are significantly more likely to commit crimes than women in virtually all cultures. Crimes committed by men also tend to be more severe than those committed by women.
Crime distribution shows a
long tail with a small fraction of individuals re-offending many times due to high
recidivism, while onset of crime at younger age predicts a longer criminal career.
