This collection of datasets from the NCRB Prison Statistics India reports provides a comprehensive analysis of sentencing trends and the duration of confinement for both convicts and undertrials. For convicted prisoners, the data tracks judicial outcomes ranging from capital punishment and life imprisonment to shorter terms (from under 6 months to 13 years), including the execution of death sentences and the percentage share of each sentence category. A critical subset highlights the "fine-default" crisis, documenting convicts who remain incarcerated for periods of under 6 months to over 5 years solely due to the non-payment of court-ordered fines. For undertrial prisoners, the collection monitors the length of pre-trial detention across intervals from under 3 months to over 5 years. Available at both national and state levels in absolute numbers and percentage shares, these datasets are essential for identifying judicial delays and assessing the efficiency of the Indian criminal justice system. Together, they offer a transparent look at how sentencing severity and legal bottlenecks contribute to the long-term occupancy of India’s correctional facilities.
