CRM 6325 Why Numbers on Crime and Justice? “He uses statistics as a drunken man uses lamp posts -- for support rather than illumination.” Andrew Lang (1844 - 1912), The Columbia World of Quotations Statistics can provide excellent context, authority (…and illumination) to research Many sources of statistics on crime and justice (which is good news and bad news)
4
CRM 6325 We have Criteria for evaluating Statistical Sources Who is collecting the data? –What is their reputation for accuracy and objectivity ? Can you review their data and methodology? Does the provider make this information available? Who is the sponsor of the data collection? –What is their agenda? E.g., a political party or toothpaste manufacturer have defined agendas

CRM 6325 Where to Dig for Data? CHECK OUT THESE TWO PUBLIC SOURCES FOR HOMICIDE STATISTICS… 1)http://www.nraila.org/Issues/Articles/Read.aspx?ID=72http://www.nraila.org/Issues/Articles/Read.aspx?ID=72 2)http://www.statcan.ca/Daily/English/081023/d081023a.htmhttp://www.statcan.ca/Daily/English/081023/d081023a.htm ROW 1 - Who collected the data? ROW 2 – How was the data collected (methodology…)? ROW 3 - Who sponsored the collection &/or publication? ROW 4 – What was the sponsor’s mandate?

CRM 6325 Statistics can be presented in many ways, as… - a table of numbers, - a few numbers in an article or Web site,, - a graph, * * see Graph types and …Graph types
14
CRM 6325 … AS A MAP Beware of ecological fallacies
15
CRM 6325 Statistics WHERE ARE THE PEOPLE or INCIDENTS…? In Canada, Statistics Canada has Standard Geography CRIMES: –Municipal police: Census Metropolitan Areas generally (Ottawa without Gatineau is an exception) –North / rural RCMP: Census Division or counties Injuries, cause of death, diseases and conditions (e.g., depression) –Health regions: regions for provincial health services, e.g., injuries Everything else: –Province/country – and the Census (socio-demographic) in particular has very detailed geography

17
CRM 6325 … Who’s Got Numbers? A Whole Lot of places you can find numbers, Of varying degrees of reliability! …so Where to Start to Dig?
18
CRM 6325 Before You Dig How much do you need – A few numbers, lots of numbers to compare (e.g., crime over time, factors relating to crime), or extensive detailled numbers (e.g., crime by city and gender of offender…)? Will you know how to use it? If you think there may be a good in-depth source for numbers, ask for help.
19
CRM 6325 Are there any statistics on your Topic? Check official sources – these are often primary sources (excellent!) note, the United Nations is not an official source for crime statistics (go to the country’s national statistical agency)
20
CRM 6325 Official Statistical Agencies Governments and international agencies produce a lot of statistics Most governments have an official agency to carry surveys, gather data (e.g., from the provinces, analyse data, develop statistical products and publish their results E.g.: –Statistics Canada –--- Canadian Centre for Justice Statistics –U.S. Census Bureau –Office for National Statistics (UK) The University of Ottawa is a member of the Data Liberation Initiative – DLI between the Library and Statistics Canada
21
CRM 6325 Before you dig Where will you dig? –Start by circling the official agency site to know if you should dig!! (Are you likely to find anything??)
