What this dot point is asking
Eduqas wants you to know the main ways crime is measured, official statistics, victim surveys and self-report studies, the idea of the dark figure of crime, and the strengths and weaknesses of each source. This dot point links the crime topic to the research methods topic, since it is really about the reliability and validity of secondary data.
Official statistics
Because of the dark figure, official statistics may measure how crime is reported and recorded rather than how much crime really happens. This is why interpretivists argue they are socially constructed, reflecting the decisions of victims and the police, not simply objective facts. The same point appears in the secondary sources topic.
Victim surveys and self-report studies
Each has strengths and weaknesses:
- Victim surveys capture unreported crime and show how crime affects victims, but rely on memory, may miss crimes the victim does not know about, and exclude crimes against businesses or where the victim cannot be asked.
- Self-report studies reveal hidden offending, including crimes that never reach the police, but rely on people being honest about breaking the law, so respondents may exaggerate or hide their offences.
Putting the sources together
No single source measures crime perfectly. Official statistics, victim surveys and self-report studies each capture a different part of the picture and each has blind spots. Sociologists therefore use them together and treat all crime data critically, asking what each source includes and excludes. A strong answer shows that the "true" rate of crime is hard to know, which is why the way crime is measured is itself an important sociological question.

Eduqas 20192 marksDescribe what is meant by the dark figure of crime.Show worked answer →
A two-mark describe item: define the term clearly.
The dark figure of crime is the amount of crime that is not recorded in official statistics, because it is not reported to the police or not recorded by them.
Markers reward an accurate definition (unrecorded or hidden crime). Linking it to the gap between real crime and recorded crime strengthens it.
Eduqas 20218 marksExplain the strengths and weaknesses of victim surveys as a way of measuring crime.Show worked answer →
An eight-mark explain item: developed strengths and weaknesses, no formal evaluation needed.
Strengths: victim surveys (such as the Crime Survey for England and Wales) ask people directly about crimes committed against them, so they capture crime not reported to the police and help reveal the dark figure, giving a fuller picture than police statistics. They also show how crime affects victims.
Weaknesses: they rely on memory, so people may forget or misremember; they may miss certain crimes (such as those against businesses, or where the victim does not know a crime occurred); and some victims may not take part or may not tell the truth.
A further point strengthens the answer: victimless crimes and crimes against the very young or those who have died are missed. Markers reward developed strengths and weaknesses tied to the accuracy of measuring crime.
