Police open-data incidents are published as the centre of a 500 m grid square; an incident counts for the neighbourhood when that centre falls inside its outline. The counts therefore indicate scale rather than an exact tally.

Data, method and limits

Data

Method

Crime: police open-data incidents, weighted by severity and population (a relative index; only grid cells with at least 10 incidents in 2 years count). Air: share of good (EAQI 1–2) and poor (4–5) hours over the last 90 days of measurements. Noise: mean Lden of the strategic noise map across the neighbourhood; unmapped areas are not counted. Radon: modelled indoor level, not a measurement of a specific flat. The figures compare areas; they do not rate a single building.

Limits

A registered incident is not the same as an offence that happened; reporting varies. Air values are class values, not exact concentrations, and PM2.5 is not available. The figures describe an area as a whole, not a specific street or building, and do not replace a visit or the official overviews. A neighbourhood's value is the average of the grid cells inside its outline; for a neighbourhood smaller than one cell the nearest cell is used and the page says so.
