Deviance

Definition

Behaviour that violates social norms, whether or not it is also illegal. Criminology studies deviance as well as crime because the boundary between them shifts with time, place, and law, and because many harmful behaviours fall outside formal criminal law.

Field
Criminology
Definition basis
Violation of social norms, legal or not
Contrast
Broader than crime, which is norm violation codified in law
Why studied
The line between deviance and crime shifts across time and place

Common questions

Can something be deviant without being a crime, or a crime without being deviant?+

Yes to both: wearing unusual clothing in public is deviant in many settings but not illegal, while some acts that are technically illegal in a jurisdiction, such as jaywalking, may not be widely regarded as socially deviant, which is exactly why criminologists treat the two as related but separate categories.

Why does the shifting boundary between deviance and crime matter for policy?+

Behaviours move in and out of the criminal code as social attitudes change, such as changing laws around drug use or sexuality in various jurisdictions, so studying deviance broadly helps explain why criminalisation happens and shifts, rather than treating the current legal code as a fixed, natural boundary.
