In the sociological field, crime is the breach of a rule or law for which some governing authority or force may ultimately prescribe a punishment. The word crime originates from the Latin crimen (genitive criminis), from the Latin root cernō and Greek κρινω = "I judge". Originally it meant "charge (in law), guilt, accusation."

When society deems informal relationships and sanctions insufficient to create and maintain a desired social order, there may result more formalized systems of social control imposed by a government, or more broadly, by a State. With the institutional and legal machinery at their disposal, agents of the State are able to compel individuals to conform to behavioural codes and punish those that do not. Various mechanisms are employed to regulate behaviour, including rules codified into laws, policing people to ensure they comply with those laws, and other policies and practices designed to prevent crime. In addition are remedies and sanctions, and collectively these constitute a criminal justice system. Not all breaches of the law, however, are considered crimes, for example, breaches of contract and other civil law offences. The label of "crime" and the accompanying social stigma are normally reserved for those activities that are injurious to the general population or the State, including some that cause serious loss or damage to individuals. The label is intended to assert an hegemony of a dominant population, or to reflect a consensus of condemnation for the identified behavior and to justify a punishment imposed by the State, in the event that an accused person is tried and convicted of a crime. Usually, the perpetrator of the crime is a natural person, but in some jurisdictions and in some moral environments, legal persons are also considered to have the capability of committing crimes.

Definition

A normative definition views crime as deviant behavior that violates prevailing norms cultural standards prescribing how humans ought to behave normally. This approach considers the complex realities surrounding the concept of crime and seeks to understand how changing social, political, psychological, and economic conditions may affect the current definitions of crime and the form of the legal, law enforcement, and penis responses made by society. These structural realities are fluid and often contentious. For example, as cultures change and the political environment shifts, behavior may be criminalised or decriminalised, which will directly affect the statistical crime rates, determine the allocation of resources for the enforcement of such laws, and influence the general public opinion. Similarly, changes in the way that crime data are collected and/or calculated may affect the public perceptions of the extent of any given "crime problem". All such adjustments to crime statistics, allied with the experience of people in their everyday lives, shape attitudes on the extent to which law should be used to enforce any particular social norm. There are many ways in which behaviour can be controlled without having to resort to the criminal justice system. Indeed, in those cases where there is no clear consensus on the given norm, the use of criminal law by the group in power to prohibit the behaviour of another group may be considered an improper limitation of the second group's freedom, and the ordinary members of society may lose some of their respect for the law in general whether the disputed law is actively enforced or not.
