What are the two most pressing concerns in crime statistics and data collection?
Reliability: Are the methods strong enough that anyone following the procedures would produce the same counts?
Validity: Do the statistics collected count what they purport to count
Describe coverage and methodology as concerns over counting crime
Coverage: How can we obtain reliable and valid data on the scope and nature of crime?
Methodology: Do the methods used to count crime hold up under critical analysis
Describe the idea of crime being a funnel
Police cannot record unreported crime or crime of which they are unaware
funnel diagram example : Only 1% of all break and enters were actually sentenced to custody. from reports to convicts to custody, the percentage gets smaller and smaller
Shows that the further into the CJS you go, the more obvious it becomes that you are collecting statistics on how the CJS operates rather than a measure of the actual scope and nature of crime
Theories and facts are mutually dependent.
Theory without facts is ______
Facts without theory is _______
Statistics without theory is ______
Ideology
Implicit ideology
numerology
What are the three broad types of criminal justice statistics?
What are some examples of raw data that the CJS produces?
Police reports and records, court decisions, administrative records of prisons and penitentiaries, decisions of parole and probation officials
What is the difference between records and statistics?
Records = concerned with individual cases (ex. an offender) > can help practitioners make decisions about these individual cases
Statistics = aggregated and concerned with what’s common among many individual cases > they provide information about larger questions: planning and evaluation, policy and program development, etc.
What are the five methodological issues that we need to consider when changing records into usable statistics?
What is the CCJS and when was it founded? Which of its data is good and which has improved?
Canadian Centre for Justice Statistics > Founded in 1981 to collect national data on crime and justice
Its data on CJS inputs (resources, expenditure) are good
Its data on criminal incidents, arrests, charges, convictions, and dispositions have improved
What is the major problem of crime statistics and why its problematic?
The dark figure of crime > tons of crime that remains unreported, unrecorded, or just unknown
What are the three dominant ways to count crime or describe crime patterns and trends?
What is UCR and what is its goal?
Uniform Crime Reports
Goal is to provide uniform and comparable national statistics
What are the two versions of UCR?
UCR Aggregate (UCR1.0)
*since 1962
Survey: collects summary data for 100 separate criminal offences
UCR Incident-Based (UCR2.0) *since the mid 80s
Survey: collects more detailed information on each incident, victims, and accused
What is the Seriousness Rule in UCR statistics and what are the implications of this rule?
Rule > only the most serious crime is scored in an incident involving several crimes
*used with UCR1.0 but not with UCR2.0 because that one allows up to 4 violations per incident, permitting the identification of lesser offences
Implications:
- deflates the total crime count
- inflates serious crimes as a percentage of the total
- not enough qualitative data about crimes are recorded to use a sophisticated scale of seriousness
Why are gross counts of crime misleading?
It doesn’t differentiate between serious (indictable) and less serious (summary) offences
List some concerns of UCR Official Statistics
Describe how UCR official statistics may actually be telling us more about police activities
The UCR aggregate crime rate is expressed as a number of criminal incidents for every ________ Canadians. Why is the use of a rate helpful?
100 000
> allows for comparisons between jurisdictions or over time
> is not influenced by differences in population size between jurisdictions, or changes in population size in one jurisdiction
Describe what issue the Crime Severity Index addresses and how it’s calculated.
*available from 1998
Addresses the matter of the crime rate being driven by high volumes of less serious offences
Calculated by assigning each offence a weight derived from sentences given by the criminal courts
> the more serious the average sentence, the greater the weight
> therefore, more serious offences have a greater impact on the severity index
What is a victimization survey and what are some things victims may be asked to describe?
A victimization survey asks a sample of people, via questionnaire survey, whether they have been a crime victim
May be asked to describe…
- nature and consequences of their victimization
- whether it was reported to police and if not why
- the CJS response
- the perceptions of, and attitudes toward, crime and the CJS, and their feelings of safety
What are some limitations of victimization surveys?
What are some lessons that have been learned from victimization surveys?
Which age group experiences the highest amount of victimization?
Age 20-24
What is the most common type of self-report study?
Those administered among a specific population (ex. secondary school students)
> asked about whether they have committed a crime, the nature of the crime, and when
