What it means
This looks at serious crime signals where official records are available. It should always be read with local context.
How we calculate it
We compare reported serious crime signals against the broader set of cities. Lower reported risk improves the safety signal.
Sources and freshness
FBI CDE, local public safety records, UNODC, and vetted regional records.
Source periods vary by place. City pages show dated source context for the applicable measure when it is available.
Limitations
Reporting practices, definitions, coverage periods, and underreporting vary. Citywide data may not describe a particular neighborhood.
