What this dot point is asking

OCR Component 3 Section B (Crime and deviance) begins with defining crime and deviance and measuring crime. You need the three sources (official statistics, victim surveys, self-report studies), the concept of the dark figure of crime, and the interpretivist argument that crime statistics are socially constructed. This underpins every later theory, because how we measure crime shapes what we think causes it.

The answer

Defining crime and deviance

The three sources of crime data

  • Official statistics are compiled from crimes recorded by the police and dealt with by the courts. They are cheap, cover the whole country, and show trends and basic patterns (by age, gender, area), but they capture only reported and recorded crime.
  • Victim surveys, such as the Crime Survey for England and Wales (CSEW), ask a large sample about their experience of victimisation, whether or not it was reported. They reveal more crime than the police figures but rely on memory and honesty and exclude some groups (the homeless) and offences (corporate crime).
  • Self-report studies ask people, often anonymously, what offences they have committed. They uncover hidden offending and show crime is more widespread than police data suggest, but raise issues of truthfulness and sampling.

The dark figure and social construction

The dark figure of crime is the large amount of crime that never appears in official statistics. It exists because victims do not always report (seeing crimes as trivial, fearing reprisals or distrusting the police) and because the police use discretion and recording rules, so not all reported crime is recorded. Positivists treat statistics as social facts useful for finding patterns; interpretivists argue they are socially constructed by the decisions of victims, police and courts, telling us as much about the reaction to crime as about crime itself.

Examples in context

A top answer treats statistics as socially constructed, weighs official, victim and self-report data, and judges which gives the best picture, rather than trusting any single source.

Q1. Outline two sources of data on crime besides official statistics. [4 marks]

  • What the marker wants. Two sources (AO1, two marks each): victim surveys (the CSEW), and self-report studies, each briefly explained.

Q2. Outline and explain two reasons why victims may not report crimes to the police. [10 marks]

  • Cue. Two developed points: seeing the crime as too trivial or private (such as some domestic incidents), and fear of reprisals or distrust of the police, each applied to an example and linked to the dark figure of crime.

A short Section B knowledge question (AO1, three marks per reason). Identify a reason and develop it.

Reason one. Non-reporting: many crimes are never reported to the police because victims see them as too trivial, fear reprisals or distrust the police, for example unreported domestic abuse, leaving a dark figure of crime.

Reason two. Police recording practices: the police use discretion and recording rules, so not all reported crimes are recorded, for example incidents downgraded or not logged. Develop each reason for the second mark.

For. Official statistics are cheap, large-scale and show trends over time; positivists treat them as social facts useful for spotting patterns by age, gender and area.

Against. Interpretivists argue they are socially constructed: non-reporting, police discretion and recording rules create a dark figure of crime; victim surveys (the CSEW) and self-report studies reveal far more crime, though they too have limits.

Judgement. Official statistics are useful for trends but understate the true extent of crime, so they must be combined with victim and self-report data. This balance reaches the top band.
