Lec 3 Flashcards
Implications of crime data controversies
The official reported crime is a reflection of how the CJS operates rather than measuring crime
Crime counts in Canada is undermined
Therefore using crime statistics to make theories may not be valid
Dark figure of crime
Crimes that do not get reported
Three methods of counting crime in Canada
Official statistics (Canadian Uniform Crime Reports)
Victimization surveys
Self report studies
Uniform Crime Reports (UCR)
Reflects reported crimes that the police have substantiated
What is the goal of a UCR
To provide uniform and comparable national statistics
Two versions of the UCR
UCR aggregate (UCR 1.0) Survey- Collects summary data for 100 separate criminal offences
UCR Incident-Based (UCR 2.0) Survey- collects more detailed info on only one case
UCR aggregate (UCR 1.0) data is presented as crime rate
Crime rate is a count of all criminal incidents reported to and by police divided by 100k Canadians or population of interest
Uses of crime rate
Allows for comparisons between jurisdictions or over time
It is not influenced by population size between jurisdictions or changes in one jurisdiction
Canadian Centre For Justice Statistics (CCJS)
A division of Statistics Canada
Was founded in 1981 to collect national data on crime and justice
CCJS collects, manages and analyses CJS statistics
Police reports and records
Court decisions
Administrative records of prisons
Decisions of parole and probation officials
What does the CCJS help us understand
Crime trends in Canada
CSI (Crime severity index)
Measures the varying degrees of severity of crimes by weighting each offence on a scale of seriousness
How is CSI calculated
Multiplying the number of offences by the weight for that offence, summing them up and then dividing by the population
How is each offence’s weight derived
From the sentence given by the criminal courts
Benefits or Uses of CSI:
It addresses the matter of the crime rate being driven by high volumes of less sever offences
It allows Canadians or police to identify places where the most sever and dangerous offences can occur
