The UK government has announced a £15 million investment over the next three years to upgrade national crime mapping tools in a bid to combat the growing crisis of knife crime. The Home Office stated that the initiative is designed to use more granular data analysis to help police pinpoint high-risk areas.
Currently, the mapping system divides England and Wales into 1.46 million hexagonal zones, each covering approximately 0.1 square kilometers. Home Office data shows that between April 2024 and March 2025, every recorded knife crime occurred within less than 2.5% of these zones.
Strengthening Tech-Enabled Policing
UK Research and Innovation (UKRI) will oversee the project's technical implementation. By integrating artificial intelligence, the system will achieve more efficient pattern recognition and incorporate multi-dimensional data for visual analysis. In its policy paper, "Saving Lives, Building Hope," the Home Office noted that this micro-geographic analysis will enable local authorities to identify the specific streets, times, and triggers of crimes, allowing for more effective police deployment and preventative measures.
While 2.5% may sound like a small fraction, it encompasses the jurisdictions of the Metropolitan Police, Greater Manchester Police, and West Midlands Police. These three forces handle 43% of all knife crimes in the UK. However, even within city centers, crime rates vary significantly from street to street.
In central London, for instance, the area covering Leicester Square and Trafalgar Square recorded over 45 knife crimes in the past year, while the Long Acre area of Covent Garden—just a street away—recorded fewer than five. Birmingham’s commercial district shows a similar pattern, with stark differences in crime records between adjacent blocks.
To meet the goal of halving knife crime, the government invested £5 million last year to launch "hyper-local knife crime pilots" across 11 police force areas. This year, the program will expand to 27 areas with a budget increase to £26.25 million. Beyond crime mapping, interventions include increased patrols during peak hours, the use of knife arches, and expanded CCTV coverage.
The Home Office also plans to increase the number of police vehicles equipped with Live Facial Recognition (LFR) from 10 to 50. However, the use of this technology is not without controversy. Last month, Essex Police suspended its use of LFR following a study that highlighted potential racial bias in the technology.
