Published crime rates, Hertfordshire (Hertfordshire Constabulary area)

Postcode districts and sectors ranked by published street-crime records per 1,000 Census 2021 residents, September 2025 to August 2026. Counts sit beside every rate.

These are published crime rates, not safety ratings. Expect city centres, stations and big shopping areas near the top: many people visit, few live there, and a residents-only rate counts the visitors' records against the residents alone. Published locations are approximate; they are snapped to anonymous map points before release, and each record is assigned to its nearest postcode, so records near a boundary can fall in the next area. Areas with fewer than 5,000 residents, and areas inside a force publication gap, are not ranked. Rates cover England and Wales only. How rankings are built.
