Data is provided monthly by the Calgary Police Service. This data is considered cumulative as late-reported incidents are often received well after an offence has occurred. Therefore, crime counts are subject to change as they are updated.
Crime count is based on the most serious violation (MSV) per incident. Violence: These figures include all violent crime offences as defined by the Centre for Canadian Justice Statistics Universal Crime Reporting (UCR) rules. Domestic violence is excluded. Break and Enter: Residential B&E includes both House and ‘Other’ structure break and enters due to the predominantly residential nature of this type of break in (e.g. detached garages, sheds). B&Es incidents include attempts.

In addition to monitoring crime levels, the Calgary Police Service uses a range of types of calls for service (CFS) to monitor levels of "Disorder." Research indicates that disorder can have a negative impact on public perceptions of safety. Disorder is often highly visible, occurring in public spaces; drunks, panhandling, youth gangs, prostitution, littering, loitering and graffiti are examples of signals of social and physical disorder. A very low proportion of disorder-based calls for service result in crime reports.

Disorder CFS included are: Drunk, Disturbance, Indecent Act, Landlord/tenant, Mental health concern, Neighbor dispute, Party complaint, Suspicious person, Threats, Drugs, Noise complaint, Possible gunshots, Unwanted guest/patron, Prostitution, Speeder.

Please note there has been an update to the methodology for disorder in January of 2024, including the removal of property damage and Abandoned auto, resulting in the dissolution of disorder sub-categories. Disorder counts will therefore not be directly comparable to previously published disorder reporting.

Only public-generated call types are included: Advised, Callback, and Dispatched (police-generated calls are excluded). All dispositions are included.

Events are assigned to communities based on the geocode in CAD. Count is by single event.

Data source: Computer Aided Dispatch (CAD) run on the 4th of the month (or the closest business day) for the previous month. This data is considered to be static. Property Damage occurrences reported using the online reporting system are included from the CPS records management system (SENTRY). This data is considered to be cumulative.
