This is a historical record of rain accumulated at various rain gauges throughout the City during the rain season, which typically runs from May 1- Sep 30. Readings are taken at 5 minute intervals, and updated daily. This data is QA/QC'd on an annual basis at the end of the calendar year at which time some adjustments may be made to the data. Users should keep in mind that data viewed before March 31 of the following year should be considered in a ‘raw’ state and may be subject to change. For current year, raw rainfall readings see Current Year Rainfall

Census data is an official count of dwelling units and population within those units. The data is physically collected and may be supplemented with other information such as the periodic age/gender distribution data. This additional data allows for better interpretation of the population statistics. A community district is a fixed boundary within Calgary, created by and for the Corporation. It represents a distinct geographical area of the city that is determined through the Land Development/Subdivision Process and approved by Council.

The City of Calgary has been conducting the annual Civic Census since 1958. View the citywide and ward-level counts of dwelling units and residents over the past 60 years.

The Alberta Township File identifies land (section, township, range) in a grid format known as Dominion Land Survey (DLS) system. It is a graphic representation of these section boundaries (approximately 1 mile X 1 mile). The file contains Section Boundary, Section Name, Original Road Allowance and Quarter Section attribute information.

The polygons in this file represent the section boundaries determined in 1997 by examination and review of all registered legal plans in The City of Calgary. Each section within the city limits are defined by eight quarter section pins and also boundary cadastral stations. The line work was created in 2006 from data which was formally released to The City in 1997.

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.
*Resident counts are pulled from the latest census data, and therefore undergo a change when new census data is collected and made available (typically in the summer).*

A water service pipe, also known as a water service line, is the way drinking water is delivered to each home in Calgary. The water service pipe can be thought of as two sections:
(1) From the water main to the property line: This part of the pipe is owned and maintained by The City of Calgary.
(2) From the property line to your house: This part of the pipe is owned and maintained by the homeowner.
The data shown here only relates to the portion of the water service pipe on public property, owned and operated by The City. The material on private property can be a different material, and could have been installed at a different time. The data shown on this map is subject to change due to parcel re-development or The City repair/maintenance activities. If you believe there is an error or an omission regarding to the pipe material provided on this map, please contact 311.
