Street-crime records per 1,000 residents
Published street-crime records (including anti-social behaviour), September 2025 to August 2026, per 1,000 usual residents in the Census 2021.
CM18

Essex Police
89.7
2,771 records and 25,990 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 CM18
Records by part of CM18: the south-west 762, the west 603, the north-east 567, the north-west 329, the north 318, the east 245, the south-east 63, the south 50, the centre 9.
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 CM18's postcodes; darker ones hold more records. Hexagons at the edge also hold records from neighbouring districts, and CM18'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 CM18 records cluster in, not where incidents happened. Explore CM18 on the crime map.

Is CM18 safe?
We don't label places safe or unsafe, because published police records can't show that. This is what they show for CM18 from September 2025 to August 2026.
About 231 records a month. The busiest month was June 2026, with 304.
Records here changed by +5.0% on the 12 months before, against +7.7% across the Essex Police area, the main force here with 99.0% of CM18's records, over the same months.
Violence and sexual offences is the largest category, at 43.2% of records, against 35.5% across England and Wales over the same months.
The records can't tell you about crime nobody reported, which street in CM18 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.
Limits to keep in mind
Published locations are approximate; they are snapped to anonymous map points before release, and each record is assigned to a district by its nearest postcode. Counts near district boundaries are indicative.
These are counts of published police records, not all crime, and not a safety score.
Outcome labels in the source data are not court results or conviction rates.
Covers 100.0% of the 25,990 Census 2021 residents of CM18.

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.
