Data Sources & Disclaimer

This page explains the public data sources used on YYC-Wander.ca and the known limitations users should keep in mind.

Last updated: May 30, 2026

Overview

YYC-Wander.ca is a Calgary-focused data project that brings together public datasets, open data, and derived indicators to help users explore housing, schools, safety, community patterns, transportation accessibility, public health, economy, elections, business activity, rental markets, construction, and long-run urban trends.

Most underlying datasets originate from public sources. YYC-Wander.ca reorganizes, cleans, integrates, analyzes, and visualizes those datasets to make them easier to explore.

Original source data remains owned by its respective providers. The derived datasets, analytical structure, indicators, visualizations, accessibility indicators, address-level information matrices, and presentation created by YYC-Wander.ca are original works of YYC-Wander.ca.

Main Data Sources

Housing Market

CREB monthly public market statistics, including benchmark prices, sales, new listings, inventory, months of supply, and sales-to-new-listings ratio.

City of Calgary census, community profiles, Statistics Canada datasets, and related public demographic, population, dwelling, and neighbourhood indicators.

Municipal Elections

City of Calgary municipal election and voter turnout records used to explore participation patterns across wards, elections, and time where public data is available.

Transit & Accessibility

Calgary Transit stop data, public transit information, public road network information, and other publicly available geographic reference datasets used to support transit and accessibility analysis.

Daily Destinations & Accessibility

Publicly available geographic, transportation, and location datasets are used to support accessibility estimates for schools, LRT stations, grocery stores, malls, parks, hospitals, downtown, and other daily destinations.

Economy & Labour

Statistics Canada, Bank of Canada, Alberta and Calgary economic indicators, labour market data, wage data, industry employment, oil price context, migration, business counts, and related economic datasets.

Construction & Housing Supply

CMHC housing starts and completions, City of Calgary building permit data, and other public construction indicators used to understand housing supply trends.

Public Health

Publicly available Alberta and Calgary health-related datasets, including emergency department visits, EMS opioid responses, acute substance-related harms, opioid death locations, and naloxone distribution data where available.

Baby Names

Alberta Vital Statistics baby name datasets used to explore name popularity and long-term naming trends.

Council & Civic Records

City of Calgary public civic records, meeting records, and related municipal sources where used for civic or council-related analysis.

School Rankings

Where school ranking references appear, they are based on publicly available third-party ranking information. Original rankings remain owned by their original publisher and are not claimed by YYC-Wander.ca.

How the Data Is Presented

YYC-Wander.ca does not simply republish raw datasets. Public data is compiled, organized, summarized, and visualized to support practical exploration by residents, researchers, volunteers, and community users.

Examples of derived work include address-level property information matrices, matched school indicators, daily accessibility and commute indicators, community crime trend comparisons, disorder pressure indexes, assessment value indexes, property tax indexes, community density indexes, housing age indexes, rental affordability comparisons, business trend analysis, election participation views, and travel accessibility indicators.

Year-over-year comparisons generally compare the same period in the prior year where the source data supports that comparison. Community-level analysis uses official or publicly available community boundaries where possible. Address-level information is based on available public records and geographic context.

Data Notes

  • Housing market indicators may use public monthly data such as benchmark prices, sales, listings, inventory, months of supply, and sales-to-new-listings ratio.
  • Property assessment and tax views use public assessment and tax-related records to support long-term trend comparison. They are not appraisals or tax advice.
  • Crime indicators are based on reported incidents. They do not measure unreported crime and should not be interpreted as a complete safety rating.
  • Crime severity comparisons use broader statistical datasets and are intended for city-level context, not property-level safety conclusions.
  • School information may include school capacity, enrolment, attendance areas, matched schools, or public education indicators. School eligibility should always be confirmed with the relevant school board.
  • Accessibility indicators are estimates based on available public geographic, transportation, and location data. Results may differ from real-world conditions.
  • Rental affordability indicators use public rental, vacancy, income, or housing market data where available. Rental listings and market conditions can change quickly.
  • Business and labour indicators are based on public employment, wage, licence, classification, and business count datasets. They are useful for trend context but should not be treated as business advice.
  • Public health indicators reflect public reporting systems and may involve suppression, aggregation, delay, or geographic generalization.
  • Community indexes are designed for comparison and context. They are analytical indicators, not official ratings or government classifications.
  • Property information is based on public data and derived analysis. It should not replace legal, appraisal, inspection, insurance, or professional real estate advice.

Open Data and Attribution

YYC-Wander.ca uses public and open datasets from government agencies, public institutions, school boards, and other organizations. Many of these sources are provided under open government, open data, public reporting, or public information terms.

Use of those public datasets does not imply endorsement by the original data providers. YYC-Wander.ca is an independent project and is not affiliated with or endorsed by the City of Calgary, Calgary Police Service, Calgary Board of Education, Calgary Catholic School District, CREB, Statistics Canada, Bank of Canada, Alberta Education, Calgary Transit, CMHC, Alberta Health Services, Fraser Institute, or any other data provider unless explicitly stated.

Users who need official records should consult the original data provider directly.

Known Limitations

  • Reporting bias: Some datasets reflect reported events, not all events that actually occurred.
  • Time lag: Public datasets are updated at different frequencies. Some data may be delayed, revised, or incomplete.
  • Geographic precision: Some records may be aggregated, generalized, anonymized, or geocoded approximately for privacy and reporting reasons.
  • Boundary changes: Community boundaries, school boundaries, service areas, electoral boundaries, and administrative definitions may change over time.
  • Coverage gaps: Some properties, communities, schools, businesses, or time periods may have limited or missing data.
  • Accessibility estimates: Travel times and distances are estimates based on available geographic, transportation, and location data. Weather, construction, traffic, closures, school drop-off congestion, and real-world conditions may affect actual travel.
  • Rental market volatility: Rental listings, asking rents, vacancies, and market conditions can change quickly and may not represent the exact rent available to a specific household.
  • School assignment limits: Public school boundaries, programs, capacity, overflow rules, and eligibility conditions may change. Users should verify school placement with the relevant school board.
  • Public health interpretation: Public health datasets may use aggregated reporting, suppressed values, delayed updates, or changing definitions over time.
  • Data quality: Public datasets may contain errors, omissions, duplicate records, outdated values, or inconsistent naming conventions.
