All edits are examined at the CCJCSS with the objective of identifying possible problems with the respondent system interface or with respondent adherence to survey data requirements. Any problems are followed up on directly with the respondent.
Edit reports are also sent to the respondents for their information and data correction.. The most significant loss of information occurs in the rare situation where a police service, because of technical or resource difficulties, is unable to submit a full year of data to the CCJCSS.
If they had previously reported to UCR, historical imputation is done based on the same months from the most recent year for which data are available or, where applicable, five years of data are used to create a time series model for the missing data. Imputation is used for the UCR2 Incident-based survey. The automated edits look for unexpected code values and will substitute a more meaningful code value given the information available within a variable and between variables. Data are imputed for two reasons: one, a blank field was submitted when "not applicable" should have been selected; and two, due to an inter-field edit, deterministic imputation is performed e.
All police services are asked to review summary data tables for completeness and accuracy and, where necessary, adjustments are made before the final file is created. These tables contain information including a year-over-year comparison--using the current reporting year and the most recent prior year--which are examined to ensure that the percent changes reported by the CCJCSS are consistent with those identified by the police service.
Upon completion of the verification process, and prior to final release, each police service is given the opportunity to review and "sign off" on their data.
Comparing UCR Data with Courts and Corrections Data: It is difficult to make comparisons between data reported by police and data from other sectors of the criminal justice system i. There is no single unit of count i. As well, charges actually laid can be different from the most serious offence by which incidents are categorized. In addition, the number and type of charges laid by police may change at the pre-court stage or during the court process. Time lags between the various stages of the justice process also make comparisons difficult..
Statistics Canada is prohibited by law from releasing any data which would divulge information obtained under the Statistics Act that relates to any identifiable person, business or organization without the prior knowledge or the consent in writing of that person, business or organization.
Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data. More specifically, CCJCSS does not release any tables or cross-tabulations that may identify a particular victim or suspect by the specifics of an offence..
Revisions are accepted for a one-year period after the data is initially released. For example, when data is released in July , data is updated with any revisions that have been made between May and May Each year of data is revised only once and then permanently frozen.. Data collected through the UCR Survey represents a subset of all crimes occurring in Canada, but is an accurate measure of the number of incidents of crime being reported to the police. The quality and accuracy of data submitted through to the UCR Survey is checked through a series of programs which identify duplicates, missing or incorrect information.
Issues identified through this processes are shared with police services so that corrections can be made. The CCJCSS does not conduct audits of police department's records management units to ensure complete and accurate reporting. Nor does the CCJCSS examine records which the police have processed and determined to be outside the scope of the survey.
Adjustments to the UCR Survey, such as the addition of new offences or changes in the severity of those that exist are made in response to Federal Legislation changes. Adjustments may also be made in response to suggestions and commentary from both police services and data users which are intended to improve the quality and usability of data collected through the UCR survey.
This can affect data comparisons over time. The UCR Survey classifies incidents according to the most serious offence MSO occurring in the incident generally the offence which carries the longest maximum sentence under the Criminal Code of Canada. In categorizing incidents, violent offences always take precedence over non-violent offences. For example, an incident involving both a breaking and entering offence and an assault is counted as an incident of assault.
As a result of the MSO scoring rule, less serious offences are under-counted by the aggregate survey. However, the incident-based survey allows up to four violations per incident, permitting the identification of lesser offences. All provinces and territories are now surveyed almost entirely under the UCR2 program. The coverage provided by these services in the database is distributed as follows: Please note that coverage is expressed as the proportion of the Canadian population covered by the UCR2 survey.
Continuity with the UCR1 aggregate survey data is maintained by a conversion of the incident-based data to aggregate counts at year-end.. Please contact us and let us know how we can help you.

Participation by all criminal justice agencies in the state program is necessary to remain in compliance with both Nevada Revised Statute A.
The Nevada UCR program, housed within the Records Bureau, collects crime statistics from state law enforcement agencies and publishes the results for use in national and state summaries. The UCR program provides a standardized form for police to report all index crimes , domestic violence incidents and crimes against the elderly within their jurisdiction.
The law enforcement community called for a thorough study of UCR with the objective of recommending an expanded and enhanced program to meet future law enforcement needs. Due to the new requirements, all agencies in the state must transition from submitting crime statistics to the state via SRS methodology to using the NIBRS methodology.
