Three Rivers crime rate and statistics (council area)

Updated October 2026.

Police published 6,483 street-crime records for the Three Rivers council area from September 2025 to August 2026. That is 5.8% more than in the 12 months before. The rate is 69.0 per 1,000 residents counted in the Census 2021, against 91.4 for Hertfordshire Constabulary. A residents-only rate reads high where many people visit. Police locations are approximate.

These figures cover the whole area Three Rivers council runs. Its boundary can differ from the place people call Three Rivers: it can take in other towns and villages, and part of a town can sit in a neighbouring council area.

Residents are the Census 2021 usual residents of every postcode the ONS Postcode Directory places in this council area, added up by CrimeMapsUK from the census postcode counts. Records are assigned through the same postcodes, so both numbers cover the same ground. The total can differ slightly from the council's official population.

6,483 records and 93,900 residents. Residents-only rates overstate crime where many people visit who do not live there, such as city centres, stations, and retail parks. Residents are counted at March 2021 while records are current, so areas with many newer homes can read higher.

No England and Wales comparison is shown, because not every force involved has published every month of this window.

Rates cover England and Wales only. Residents: Office for National Statistics, Census 2021 postcode estimates, Open Government Licence v3.0. How rates are built.

North is at the top. Each hexagon is about 1.2 km across, the size the crime map uses zoomed out, and holds at least one of the Three Rivers council area's postcodes; darker ones hold more records. Hexagons at the edge also hold records from neighbouring council areas, and the Three Rivers council area's records placed outside these hexagons are not drawn, so the map's counts won't add up to the page's total. Police place each record at an approximate public point, so this shows which parts of the Three Rivers council area records cluster in, not where incidents happened.

Limits to keep in mind

A council area follows the council's boundary (ONS local authority district E07000102), which can differ from the place people call Three Rivers.
Published locations are approximate, and each record counts for the council area of its nearest postcode, using the council codes in the ONS Postcode Directory. Counts near the boundary are indicative.
These are counts of published police records, not all crime, and not a safety score.
Other sites can show a different figure for Three Rivers. These counts include anti-social behaviour, cover the 12 published months shown, and assign each record by its nearest postcode. The rate divides by Census 2021 residents of the same postcodes, not by a later mid-year population estimate.
Full detail is on the methodology page.
