Published street-crime records (including anti-social behaviour), September 2025 to August 2026, per 1,000 usual residents in the Census 2021.

CM17

71.9

Essex Police

89.7

1,861 records and 25,884 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.

Where records cluster in CM17

Published street-crime records in CM17, September 2025 to August 2026, grouped into hexagons

Records by part of CM17: the west 1,015, the north-west 582, the south-west 62, the north-east 21, the north 4, the east 3.

North is at the top. Each hexagon is about 290 m across, the size the crime map uses zoomed in, and holds at least one of CM17's postcodes; darker ones hold more records. Hexagons at the edge also hold records from neighbouring districts, and CM17'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 CM17 records cluster in, not where incidents happened. Explore CM17 on the crime map.

Is CM17 safe?

We don't label places safe or unsafe, because published police records can't show that. This is what they show for CM17 from September 2025 to August 2026.

The records can't tell you about crime nobody reported, which street in CM17 a record came from, or how a place feels at different times of day. The rate per 1,000 residents is above. See the limits to keep in mind.

Deprivation where residents live

Covers 100.0% of the 25,884 Census 2021 residents of CM17.

England: English Indices of Deprivation 2025

Of these residents in England, 0.0% live in the most deprived 20% of England's neighbourhoods and 34.8% in the least deprived 20%.

Share of residents in each decile, from 1 (most deprived) to 10 (least deprived) of England's small areas. Shares are rounded, so they may not total 100%.

Deciles rank neighbourhoods within one nation, so English and Welsh deciles don't compare. They describe areas, not the people living in them, and crime is one of the things the index measures, so this mix partly overlaps the crime figures above. How this is built.
