In short

Criminological theory is the body of systematic explanations of why crime happens, why it is distributed unevenly across people and places, and why society responds to it as it does. It runs from the pre-classical demonological view through the classical school (free will and deterrence), positivism (biological, psychological and sociological causes), social process and reaction theories, to conflict, feminist and life-course criminology. It matters because every criminal justice policy rests on a theory: deterrence sentencing on classicism, probation and reformatories on positivism, Safe City projects and CCTV on routine activity, and the restorative provisions of the Bharatiya Nyaya Sanhita, 2023 and the Probation of Offenders Act, 1958 on reintegration. It is the highest-weight unit in BA/B.Sc Criminology "Foundations" papers, in UGC-NET Criminology, and in recruitment and interview rounds for police, prisons, probation, BPR&D and NGO research posts, where candidates are asked to explain NCRB crime patterns using a named theory.

Key points

Formulas and examples

Crime rate = (number of cognizable offences reported) ÷ (mid-year population in lakh) - NCRB convention is per 1,00,000 population; state the offence head and year.
Crime share (%) = (offences in the unit ÷ all-India offences) × 100
Chargesheeting rate (%) = (cases chargesheeted ÷ cases in which investigation was completed) × 100
Conviction rate (%) = (cases convicted ÷ cases in which trial was completed) × 100
Pendency percentage = (cases pending at year end ÷ total cases for trial or investigation) × 100
Recidivism rate (%) = (released prisoners reconvicted within the follow-up period ÷ total released) × 100
Dark figure (%) = [(victimisations in survey − victimisations reported to police) ÷ victimisations in survey] × 100
Deterrence (expected utility): commit if G > p × q × C, where G = expected gain (₹), p = probability of arrest, q = probability of conviction given arrest, C = money-equivalent cost of punishment (₹). Threshold arrest probability p\* = G ÷ (q × C).
Situational Action Theory (conceptual): crime propensity × criminogenic exposure → crime; propensity is low morality plus low self-control.

Example 1 - crime rate and comparison. A district with a mid-year population of 24,00,000 records 7,560 cognizable offences; the state rate is 280 per lakh.

Example 2 - investigation and trial performance. Of 5,000 cases where investigation was completed, 4,200 were chargesheeted; trials were completed in 2,300 cases, of which 1,150 ended in conviction.

Example 3 - deterrence threshold. Expected gain from a theft G = ₹50,000; probability of conviction given arrest q = 0.5; money-equivalent cost of punishment C = ₹8,00,000.

Example 4 - dark figure. A victimisation survey of 10,000 households finds 1,250 households victimised in the year; only 400 of these incidents were reported to the police.

Example 5 - recidivism and theory choice. 4,800 prisoners are released; 1,440 are reconvicted within three years. Among them, 1,080 were under 25 at release.

TheoryCore questionCause of crimePolicy it supports
Classical / rational choiceWhy is this act chosen?Free, calculated choiceCertain and swift punishment, proportionality
Biological-psychological positivismWhy this individual?Traits, deficits, developmentDiagnosis, treatment, probation
Strain / anomieWhy these classes and times?Goals-means gap, normlessnessEducation, employment, welfare
Social disorganisationWhy these places?Weak informal control, low collective efficacyCommunity policing, urban renewal
Learning (Sutherland, Akers)How is it acquired?Association, reinforcement, rationalisationPeer-group intervention, mentoring
Control (Hirschi, Reckless)Why do most conform?Weak bonds, low self-controlFamily, school and parenting programmes
LabellingWhy does it persist?Stigma, secondary devianceDiversion, decriminalisation, anonymity
Routine activityWhere and when?Opportunity and absent guardianshipCCTV, lighting, CPTED, hot-spot patrol
Conflict / feministWho defines crime?Power, class, patriarchyLaw reform, equality, victim-centred justice
