Short answers to the most common questions about the Toronto Crime Score. Each answer links to the page with the full detail.

How is the crime score calculated?

Each neighborhood gets a single score from 0 to 100, where lower is safer. It combines nine crime categories — from homicide to bicycle theft — by scaling incidents to a rate per 100,000 residents, capping each category so no single one can dominate, and weighting by severity: homicide counts most (35%), followed by shooting (25%) and assault (12%); bicycle theft counts least (2%). The weighted points add up to the final score. The full formula and category weights are in the methodology.

How often is the data updated?

The site refreshes automatically whenever the Toronto Police Service publishes a new version of its open data — the pipeline checks the source daily and updates scores only when the published data changes. The numbers themselves are annual: the current release covers calendar year 2025 crime rates, and TPS revises the dataset during the year, so scores can shift between releases. The "Last updated" stamp on the homepage always shows the data now in use.

What does “per 100k residents” mean?

Crimes per 100,000 residents — a standard normalization so neighborhoods of different sizes compare fairly. Example: 40 assaults in a 20,000-person neighborhood is 200 per 100k, while 100 assaults in a 100,000-person neighborhood is 100 per 100k — the smaller neighborhood's rate is twice as high despite fewer incidents. The compare tool and the homepage table both toggle between raw counts and per-100k rates.

What is a good crime score?

Lower is always safer. Scores fall into five bands:

  • Very Safe (≤ 15)
  • Safe (16-30)
  • Medium (31-45)
  • High (46-60)
  • Very High (> 60)

A score in the 30s, for example, sits in the middle of the pack relative to the other 158 Toronto neighborhoods. The bands describe relative levels of reported crime — not a prediction of any individual's risk.
