- 1. Collecting crime data in Canada ArchivedArticles and reports: 11-522-X200800011012Geography: CanadaDescription:
Justice surveys represent a unique type of survey undertaken by Statistics Canada. While they all essentially use administrative data, Statistics Canada has had considerable input into the type of data that is collected as well as quality assurance methods guiding the collection of this data. This is true in the areas of policing, courts and corrections. The main crime survey, the Uniform Crime Reporting Survey (UCR), is the focus of this paper and was designed to measure the incidence of crime in Canadian society and its characteristics. The data is collected by the policing community in Canada and transmitted electronically to Statistics Canada. This paper will begin by providing an overview of the survey and its distinctive properties, such as the use of intermediaries (software vendors) that convert data from the police's information systems into the UCR survey format, following nationally defined data requirements. This level of consistency is uncommon for an administrative survey and permits a variety of opportunities for improving the overall data quality and capabilities of the survey. Various methods such as quality indicators and feedback reports are used on a regular basis and frequent two-way communication takes place with the respondents to correct existing data problems and to prevent future ones. We will discuss recent improvements to both the data itself and our collection methods that have enhanced the usability of the survey. Finally, future development of the survey will be discussed including some of the challenges that currently exist as well as those still to come.

This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
Police records collected by the Federal Bureau of Investigation (FBI) through the Uniform Crime Reporting (UCR) Program are the leading source of national crime statistics. Recently, audits to correct UCR records have raised concerns as to how to handle the errors discovered in these files. Concerns centre around the methodology used to detect errors and the procedures used to correct errors once they have been discovered. This paper explores these concerns, focusing on sampling methodology, establishment of a statistical-adjustment factor, and alternative solutions. The paper distinguishes the difference between sample adjustment and sample estimates of an agency's data, and recommends sample adjustment as the most accurate way of dealing with errors.
