Notes

  • From the Monday population and capacity briefing, one file a week, which the MoJ publishes as transparency data. The population covers the adult male, female and youth custody estates. There is no briefing on a bank holiday Monday, so those weeks are gaps.
  • Useable operational capacity is the sum of every prison's operational capacity less an operating margin for places that cannot be used on a given day, because prisoners must be held by sex, age, security category and other needs. The MoJ reviews the margin regularly.
