Where records cluster in CM99
Records by part of CM99: the centre 185.
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 CM99's postcodes; darker ones hold more records. Hexagons at the edge also hold records from neighbouring districts, and CM99'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 CM99 records cluster in, not where incidents happened. Explore CM99 on the crime map.

The records can't tell you about crime nobody reported, which street in CM99 a record came from, or how a place feels at different times of day. 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 1 Census 2021 residents of CM99.

Share of residents in each decile, from 1 (most deprived) to 10 (least deprived) of England's small areas.
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.
