Criminology and criminal law are distinct fields that approach the study of crime from different perspectives.

Criminology is a social science focused on the nonlegal aspects of crime and delinquency. It utilizes diverse disciplines—such as sociology, psychology, and economics—to investigate the causes, prevention, and correction of criminal behavior. Criminologists seek to understand why individuals engage in crime and why crime rates vary across societies or over time.12

Criminal law, by contrast, is the body of law that defines specific criminal offenses, regulates the apprehension and trial of suspects, and establishes penalties for convicted offenders. While criminology examines the broader social and behavioral context of crime, criminal law functions as a regulatory device used by organized societies to protect individual interests and ensure public security.31

Ultimately, while criminal law focuses on the legal definition and punishment of individual actions, criminology provides the scientific research and theoretical framework necessary to understand the complex factors underlying those actions.13
