Legal Framework & Public Records
This project, developed by Anthony Nick (Independent Analytics Lab), operates under the UK Open Government Licence (OGL), which permits the use and re‑use of public sector information when properly attributed. All crime data is sourced from the official UK Police database (data.police.uk), published in accordance with the Crime and Disorder Act 1998.
UK policing bodies publish non-personal crime statistics to support public awareness, research, and community safety. Police forces provide approximate street‑level crime incident locations to increase transparency while protecting privacy. Red points on the map show anonymised crime locations: in the UK, each incident is snapped to the nearest neutral point — usually a street midpoint, a junction, or another public, non-residential place.
This project is an independent analytical interpretation of publicly available police data and is not affiliated with, endorsed by, or representing any UK government body or police authority.
Mapping Framework & Open Licences
This service displays geographic information using data and map tiles derived from OpenStreetMap data (© OpenStreetMap contributors), available under the Open Database License (ODbL).
To ensure performance and availability, map tiles requested by visitors’ browsers are served through an internal caching proxy. If a tile is not yet cached, the system retrieves it from the OpenStreetMap tile servers, applies a grayscale rendering for visual consistency and reduced file size, stores the processed tile, and then delivers it to the user.
The interactive map is rendered using the Leaflet library, distributed under the BSD 2‑Clause License.
All cartographic data remains the property of its respective contributors and licensors.
Methodology & Limitations
This project presents an independent analytical model designed to estimate the relative exposure to street‑level crime across urban areas based on official police data.
The current version of the map is based on official police data covering the full year of 2025. The dataset is updated only when complete annual data becomes available, ensuring consistency and comparability across all areas.
1. Crime categories are manually selected by the author based on their relevance to street‑level incidents. Categories such as residential burglary, commercial burglary, and vehicle‑related crimes are excluded, as they are less representative of direct public‑space exposure.
2. Each included crime category is assigned a severity weight on a scale from 1 to 10. These weights are informed by typical legal penalties and widely accepted assessments of crime seriousness; however, they remain an author‑defined analytical parameter and should be interpreted as such. They do not represent an official measure of personal risk or harm.
3. For each geographical unit, a yearly aggregated value is calculated as the sum of (incident count × severity weight) across all selected crime categories.
4. This aggregated value is normalized by the official surface area of the geographical unit, producing a density‑based indicator referred to as the Local "Crime Level".
5. The resulting values are visualized on a scalable map. Areas are color‑coded from green to red, where red represents zones with values approaching the upper range within the city. Clicking on an area reveals the underlying police‑reported incident counts.
6. Users can filter the map by individual crime categories, dynamically recalculating and updating the spatial distribution.
7. At higher zoom levels, individual incident points are displayed based on police‑provided geolocation data.
8. In London, the analysis is performed using a uniform 500 m × 500 m grid instead of administrative boundaries. This approach provides a more granular and location‑specific representation, reflecting the fact that crime patterns are often concentrated around specific streets and intersections rather than administrative units.
All calculations are based solely on officially recorded UK police data (Metropolitan Police and Home Office / ONS datasets) published under the Open Government Licence (OGL v3.0). Like any police-recorded dataset, the data reflects only incidents that have been reported and recorded by authorities, and reporting rates may vary across different areas. The project does not attempt to estimate unreported crime; therefore, the Local Crime Level Index represents the density of recorded incidents rather than total crime occurrence. This limitation should be considered when comparing areas, as observed differences may reflect both underlying incident levels and variations in reporting and recording practices.
This index is not an official government metric and does not measure absolute safety. It is a comparative analytical indicator intended to support spatial understanding of crime distribution patterns.
The methodology reflects an independent analytical framework and is not endorsed by any government authority.
