Read each measure in its own context.
This profile contains 4 distinct source-backed measures. Compare each figure with its reporting period and geographic scope rather than treating the page as a single safety score or personal-risk estimate.

What these numbers can—and cannot—tell you
Recorded crime depends on reporting practices, police recording systems, geographic boundaries and the period being measured. A lower figure in one category does not establish that every neighborhood, time of day or traveler faces the same risk.
When comparing cities, use like-for-like measures whenever possible. Municipality data should not be directly ranked against metro-area data or a different reporting definition without adjustment.
