The data used in the MPS Crime Dashboard is available here MPS Crime Dashboard | Metropolitan Police, along with the related data definitions. Please note that datasets are updated monthly on the 6th of the month. Data runs until the end of the month prior.
***April 2025: The Metropolitan Police Service reviewed their recording of offences where a knife or sharp instrument has been used from April 2024 onwards.
This has shown over counting for some crime types and under counting for others. These records have been corrected which has resulted in a small overall increase in crimes that have been enabled by the use or threat of a knife or sharp instrument and a small reduction in offences resulting in an injury.
Data may therefore not match earlier publications.
Previous years’ data has not been revised therefore corrected data is not directly comparable with previous years.
The offences which are included within the Knife or sharp instrument collection are specified by the Home Office. They include robbery, homicide, assault, sexual offences and threats to kill where a knife or sharp instrument has been used to threaten or to cause injury .***
***June 2024: The MPS monthly crime data-sets are now being extracted and compiled from the new CONNECT system within the MPS; these data-sets will have prefix M1045 added to the file name.***
The Metropolitan Police Service (MPS) has introduced CONNECT, a new crime recording system that consolidates several previous systems into one integrated platform. This change aims to streamline processes and enhance efficiency across the board.
At the end of February 2024 the MPS started using CONNECT to record crime and investigation data. There is a difference in how Hate Crime and Domestic Abuse are recorded on CONNECT compared with the legacy crime recording system of CRIS and for this reason, Hate Crime and Domestic Abuse figures pre an post March are not comparable.
BCU and Borough data in CONNECT are determined by the geographic location of the incident, rather than the borough managing the case, as was the case with legacy systems. This new approach has been retroactively applied to legacy data to provide consistent and comparable analysis.
Total Notifiable Offence (TNO) data follows the Home Office counting rules for recorded crime (https://www.gov.uk/government/publications/counting-rules-for-recorded-crime ). NB This data-set includes “Other Accepted Crime”, which are non-notifiable crimes and must be excluded if calculating a TNO total.
The “Other Crime” offence data follows the Home Office counting rules but have been grouped by specific features (e.g. Knife Crime): please see dashboard for definitions. NB "Hate Crime" totals do NOT include records that are flagged solely as 'domestic abuse'.
Measures include Offences, Positive Outcomes, and the Positive Outcome Rate (total number of positive outcomes divided by the total number of offences in a given period).
All data is broken down by financial year for each crime type.
