Those released from a short custodial sentence reoffend at more than twice the rate of those given a community order, but the Ministry of Justice's own guidance says these raw rates should not be used to compare the effectiveness of sentences, because they do not control for who receives which sentence.",
    "basis": "'Proven' reoffending counts only a further caution or conviction recorded within twelve months of the original disposal, plus a further six month waiting period to allow the courts to process cases, so it undercounts actual reoffending, which includes offences that are never detected or proven. The headline cohort here is offenders given a disposal in April to June 2024, the most recent published by the Ministry of Justice; because of the follow up and waiting periods, published cohorts lag roughly two years behind the date of publication. The national trend and regional breakdown use the rolling year to June 2024 from the same release, which smooths quarter to quarter noise.",

    "'Proven' reoffending is a further caution or conviction recorded within twelve months of the original disposal, followed by a further six month waiting period for cases to go through the courts. It does not capture offences that are never detected or never proven, so it understates actual reoffending. Published cohorts lag roughly two years behind the date of publication.",
    "MoJ's own guidance states: \"Proven reoffending rates by disposal (sentence type) should not be compared to assess the effectiveness of sentences, as there is no control for known differences in offender characteristics and the type of sentence given.\" (Guide to proven reoffending statistics, published April 2026, section 2.2). The figures on this page by disposal type and sentence length should be read as a description of who reoffends, not as evidence that any sentence type causes more or less reoffending.",
    "The national trend and regional breakdown use rolling year cohorts (July to June) from the geographic data tool, which differ from the single quarter cohort (April to June 2024) used for the headline and disposal breakdowns. The two sets of figures are not directly comparable to one another, though both come from the same underlying data.",
    "Regional reoffending rates are assigned by the offender's home address, not where the offence took place, and combine all disposal types and offence types for that region.",
    "Prisoner on prisoner and on staff assault counts (Table 7) do not sum exactly to the total assault incident count (Table 4) because a single incident can involve more than one assault, recorded against more than one category.",
    "Crowding is measured as the twelve months ending March 2025, the latest period published in the HMPPS Annual Digest 2024 to 2025 at time of writing; it is not the same reference date as the population and occupancy figures on the prisons deep dive, which use later 2026 snapshots.",
    "The staff in post figure (40,399) covers public sector prisons and the Youth Custody Service only. It excludes privately managed prisons, for which HMPPS does not publish a directly comparable combined workforce headcount in this release.",
    "Prison population, reconciled against the live prisons deep dive on this site: 87,342 people in custody at 31 March 2026, 96.2 per cent occupancy.",
