Canadian Incidence Study of Reported Child Abuse and Neglect (CIS)

Three nation-wide studies have been conducted with child welfare services in Canada since 1998 to determine the incidence of reported maltreatment of children under 16 years of age. These studies reveal how many child sexual abuse situations are reported to and deemed founded (substantiated) by these services over a given year, but they do not specify whether the cases identified are new or not. The Canadian Incidence Study of Reported Child Abuse and Neglect carried out in 2008 (CIS-2008) examined nearly 16 000 child maltreatment investigations conducted using a representative sample of 112 child welfare service organizations in Canada in the fall of 2008. The data were processed so that they would be representative of Canada’s population.

A Québec component of the CIS-2008 made it possible to achieve oversampling for the purpose of obtaining fair and valid provincial estimates. The Québec sample consisted of 50% of reports received in Québec during the period from October 1 to December 31, 2008. This component, called the Québec Incidence Study – QIS-2008, led to the production of a descriptive report for Québec.

General Social Survey (GSS)

Every five years, Statistics Canada publishes self-reported victimization data derived from the General Social Survey (ESG). This survey, which is conducted every five years, gathers data reported by Canadians aged 15 and over on criminal victimization experiences related to eight offences, including sexual assault, regardless of whether the experiences were reported to police or not. The most recent survey was conducted in 2009.

The GSS thus gathers information on crimes not reported to police. In 2009, such crimes accounted for roughly two thirds of criminal victimization incidents. However, the GSS relies on the memory of respondents, for it asks them to recall events precisely when they report them. Moreover, the events that respondents report to the GSS do not always meet the legal definition of a crime.
Note: The following data exclude the Northwest Territories, the Yukon and Nunavut for the 2009 GSS.

The Incident-based Uniform Crime Reporting (UCR2) Survey

The Incident-based Uniform Crime Reporting (UCR2) Survey collects detailed information on criminal incidents that have been brought to the attention of and been substantiated by Canadian police services. Every year, Statistics Canada and the Ministère de la Sécurité publique du Québec (MSP) publish annual statistics on police-reported crime in each province based on UCR2 Survey data, making it possible to document sex-related crime in Canada and Québec. The data come from 155 police services, which, in 2008, covered 98% of Canada’s population. The statistics published concern sexual assault offences (sexual assault (level 1), sexual assault with a weapon or causing bodily harm (level 2) and aggravated sexual assault (level 3)) and other sexual offences related primarily to sexual violence against children, namely, sexual interference, invitation to sexual touching, sexual exploitation, incest, non-consensual anal intercourse, anal intercourse between people under 18 years of age, bestiality, and, since 2008, corrupting children, luring a child by means of a computer and voyeurism.

**It should be noted that the annual statistics compiled by the UCR2 Survey include “historical” sexual offences, that is, offences committed several years prior to the year covered by the survey but reported in that year, as offences are recorded on the day they are reported. Sexual offences recorded against minors through the UCR2 Survey thus consist of offences committed against children under 18 years of age that were recorded in the year covered by the survey, regardless of the victims’ age at the time of reporting.

Trend data on police-reported crime

The UCR2 Trend Database contains data from the UCR2 Survey, which includes information compiled by 155 police services that covered 98% of the population of Canada in 2008, as well as information from 63 police services that consistently report data to the survey. These 63 services covered only 54% of Canada’s population in 2008.
