How Police Force Boundaries Relate to Community Data

Crime figures shown in a report are sourced from the relevant police force or government crime database, aggregated to the smallest geographic level that force or database publishes. This is not always the same boundary used to define a community elsewhere in the report.

Why boundaries can differ

A community, ward, or neighbourhood boundary is typically drawn for planning, postal, or administrative purposes. Police forces record and publish crime data against their own operational boundaries, such as a beat, a Lower Layer Super Output Area (LSOA) in England and Wales, or a police division in Scotland. These boundaries rarely align perfectly with community boundaries, and a single community can span parts of more than one police reporting area.

How this is handled in a report

Where a community spans more than one police reporting area, figures are aggregated across the relevant areas to best represent the community as defined elsewhere in the report. This means a reported figure is a close approximation of crime in that community, not a perfectly bounded count.

What this means in practice

• A busy commercial strip at the edge of a residential community can pull the reported figures upward, even if the surrounding streets see little crime
• Comparing two communities is most meaningful when both are aggregated using the same methodology, which is the case for every community shown in Uncovero
• For a very precise, address-level picture, the relevant police force's own crime mapping tool allows a search by exact location rather than by community boundary
