Vancouver Crime Observatory

Mission

The Vancouver Crime Observatory visualizes aggregated patterns of crime, justice-system effectiveness, and public spending over time and geography. Our goal is to provide fact-based transparency about crime patterns and system performance to inform public discourse and policy decisions.

System churn metrics

Release-to-recontact rate

The percentage of releases (bail, probation, etc.) that resulted in a subsequent arrest within the observation period. Calculated as an aggregate statistic by area, not by tracking individuals.

Bail violation rate

The percentage of bail releases that resulted in a breach of conditions. Calculated from anonymized, aggregated data provided through FOI requests.

Stayed charge rate

The percentage of charges that were stayed or dismissed by prosecutors or courts, rather than proceeding to conviction or acquittal.

Average time to recontact

The average number of days between a release and a subsequent arrest, calculated as an aggregate statistic across all incidents in an area.

This platform presents factual, aggregated statistics. High numbers in certain areas may reflect differences in policing practices, socioeconomic factors, population density, availability of services, or reporting patterns. Correlation does not imply causation.

Legal & ethical framework

  • All data collection and processing complies with Canadian privacy law (PIPEDA)
  • Only publicly available or FOI-accessible data is used
  • Platform design prevents misuse for harassment or targeting
  • Regular privacy audits and validation
  • Commitment to neutral, fact-based presentation
