This collection of datasets, derived from the National Crime Records Bureau (NCRB) Prison Statistics India reports, provides a detailed classification of the offences and criminal history of both convicted and undertrial prisoners. It distinguishes between crimes committed under the Indian Penal Code (IPC)—such as offences against the human body (murder, rape), property crimes (theft, burglary), and crimes against women (dowry deaths, cruelty)—and those falling under Special and Local Laws (SLL), including the NDPS Act, Arms Act, and the Prevention of Corruption Act. Beyond the nature of the charges, the collection monitors the patterns of recidivism across India, tracking the number of habitual offenders and their tendency to reoffend upon release. Available at both national and state levels, these datasets offer a critical empirical foundation for understanding the legal composition of the prison population, the prevalence of specific crime types within the judicial system, and the long-term effectiveness of rehabilitation and deterrence strategies.
