Criminology Research & Reference Center
A comprehensive reference covering major theories, core concepts, research terminology, and the connections between criminological science and community policing practice.
What Is Criminology?
Criminology is the scientific study of crime, criminal behavior, the causes and consequences of crime, and societal responses to crime. It is an empirical discipline — meaning its conclusions are based on systematic observation and evidence rather than intuition or tradition.
Criminology draws knowledge from multiple disciplines, making it broader than simply studying "criminals." It is a fundamentally interdisciplinary science.
Questions Criminology Asks
Criminology vs. Criminal Justice
Criminology
Focuses on explaining crime — its causes, patterns, and consequences.
- Why crime occurs
- Who commits crime and why
- Crime patterns across time and place
- Social and environmental causes
Core question: Why does crime occur?
Criminal Justice
Focuses on the institutions and processes that respond to crime.
- Police, courts, and corrections
- Law and procedure
- Sentencing and punishment
- Rehabilitation and reentry
Core question: How does society respond to crime?
In practice, the fields overlap significantly. Evidence-based policing, for example, draws on criminological research to improve criminal justice practice.
Historical Schools of Criminology
Classical School
1760s–1800sArgued that crime results from rational choice — individuals weigh pleasure against pain. Punishment should be swift, certain, and proportionate to deter rational actors.
Key Figures
Cesare Beccaria, Jeremy Bentham
Legacy
Foundation of deterrence theory; influenced modern criminal law and sentencing philosophy.
Positivist School
1800s–early 1900sArgued that crime is caused by factors beyond individual free will — biological, psychological, or social forces. Emphasized scientific measurement and treatment over punishment.
Key Figures
Cesare Lombroso, Enrico Ferri, Raffaele Garofalo
Legacy
Launched scientific criminology; introduced rehabilitation; later discredited biological determinism.
Chicago School
1920s–1940sFocused on how urban environments and social disorganization produce crime. Introduced ecological mapping and the concept of crime as a product of place, not just person.
Key Figures
Robert Park, Ernest Burgess, Clifford Shaw, Henry McKay
Legacy
Foundation of social disorganization theory; influenced community policing and place-based interventions.
