Survey description

Incident-based Uniform Crime Reporting Survey

The Incident-based Uniform Crime Reporting (UCR) Survey collects detailed information on criminal incidents that have come to the attention of, and have been substantiated by, police services in Canada. Information includes characteristics of victims, accused persons and incidents. In 2017, data from police services covered 99% of the population of Canada. The count for a particular year represents incidents reported during that year, regardless of when the incident actually occurred.

One incident can involve multiple offences. In order to ensure comparability, counts are presented based on the most serious offence in the incident as determined by a standard classification rule used by all police services. Counts based on all violations are available upon request.

Victim age is calculated based on the end date of an incident, as reported by the police. Some victims experience violence over a period of time, sometimes years, all of which may be considered by the police to be part of one continuous incident. Information about the number and dates of individual incidents for these victims of continuous violence is not available. Counts represent the number of victims involved in incidents of violence. It is possible that individual victims may have experienced more than one incident, and would therefore be counted more than once here.

Homicide Survey

The Homicide Survey collects detailed information on all homicide that has come to the attention of, and has been substantiated by, police services in Canada. Information includes characteristics of victims, accused persons and incidents. Since 1961 when recording began, coverage for the Homicide Survey has represented 100% of homicide in Canada. The count for a particular year represents homicide reported during that year, regardless of when the homicide actually occurred.
