Criminology (from Latin crimen, "accusation", and Ancient Greek -λογία, -logia, from λόγος logos meaning: "word, reason") is the interdisciplinary study of crime and deviant behaviour. Criminology is a multidisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, legal sociologists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, scholars of law and jurisprudence, as well as the processes that define administration of justice and the criminal justice system.
Criminologists are the people working and researching the study of crime and society's response to crime. Some criminologists examine behavioral patterns of possible criminals. Generally, criminologists conduct research and investigations, developing theories and analyzing empirical patterns.
The interests of criminologists include the study of nature of crime and criminals, origins of criminal law, etiology of crime, social reaction to crime, and the functioning of law enforcement agencies and the penal institutions. It can be broadly said that criminology directs its inquiries along three lines: first, it investigates the nature of criminal law and its administration and conditions under which it develops; second, it analyzes the causation of crime and the personality of criminals; and third, it studies the control of crime and the rehabilitation of offenders. Thus, criminology includes within its scope the activities of legislative bodies, law-enforcement agencies, judicial institutions, correctional institutions and educational, private and public social agencies.
Modern academic criminology has direct roots in the 19th-century Italian School of "criminal anthropology," which according to the historian Mary Gibson "caused a radical refocusing of criminological discussion throughout Europe and the United States from law to the criminal.
