Context

Trend context

Additional reading notes to help interpret the statistics on this page.

The latest yearly mix is led by theft, battery, and criminal damage, which helps explain how the composition of the city total changes over time.

Trend pages are meant for directional reading rather than precise forecasting, since source systems can revise historic classifications.

Methodology and caveats

These pages summarize reported public records. Use source notes and methodology before drawing comparisons.

Reported crime data can lag the real world and may exclude the most recent days.

Case classifications can change after additional investigation or administrative review.

Map coordinates are approximate because the source data is redacted to the block level.

Counts on this site summarize reported incidents and should not be treated as a complete measure of safety.

Read the methodology page for pipeline details and the about page for source notes.

FAQ

Frequently asked questions

Short answers about data coverage, definitions, and how to read these pages.

Can yearly trends be compared directly?

They can be useful directional summaries, but official caveats still apply because reporting and classification practices can shift over time.

Why show monthly and yearly views together?

Yearly views smooth short-term volatility, while monthly views make recent direction changes easier to see.
