*new request*

In December 2018 the Mayor’s Office for Policing and Crime (‘MOPAC’) published its ‘Review of the Metropolitan Police Service Gangs Matrix’.1

Following a detailed analysis, the MOPAC review concluded that:
“the percentage of black, African-Caribbean males on the Matrix exceeds that of the general population, as well as across many crime types, including those most associated with serious gang- or group-related violence.”.

The proportion of those on the matrix who were Black/African Caribbean was 80%, and BAME was 88% (p21, footnote 10).

The MOPAC report identified the percentages of those who committed a range of offences which were potentially relevant to gang activity who were Black/African-Caribbean, as compared with the percentages of Black/African-Caribbean people on the matrix, the former being much lower than the latter.

The overall proportion of those who committed relevant offences who were Black/AfricanCaribbean ranged from 25% to 75% (Graph 9, p58). Similarly, the proportions of those who were victims of those offences who are Black/ African-Caribbean ranged from 10% to 69% (Graph 10, p58).

At footnote 33 of the review, the data sources relied on by MOPAC in respect of these figures are listed as follows:

All data for offenders (PPA – Persons Proceeded against) and victims from CRIS FY2017/18 unless otherwise stated: Population projections - 2018 (GLA/London Datastore); Prolific Firearms Offenders/Habitual Knife Carriers - Nov 2018 (MPS Intelligence); GRITS (Gang Related Incident Tracking System) - 2018 to 05/11/18 (MPS Intelligence); First Time Entrants - 2017 (MoJ); GRITS [Gang Related Incident
Tracking System] - 17/18 (MPS Intelligence); Knife Possession; Knife Injury (all sub categories); Homicide (all sub categories); Firearms Discharges (Lethal barrelled weapons only); all Nov 16 to Oct 18 (MPS Performance); Matrix September 18 (MPS Intelligence).

I seek the following information:

1. The data set out in Graphs 9 and 10 of the MOPAC report, in the same format if possible, for the most recent full year (e.g. 2021-222 if a full calendar year, or say 1 May 2021 to 1 May 2022).

2. Alternatively, if the data cannot be provided in this way, please provide the MPS data referred to at footnote 33 of the MOPAC report for 2019 onwards up to and including the most recent available data.
