Positions in the middle of a group are sensitive to weighting and to chance, so the band is the more reliable guide than the position. The bar shows the likely range (5th to 95th percentile over 1,000 re-weightings and measurement uncertainty) and the tick marks the median. The four squares show the pillars in order: Safety, Decency, Regime, Resettlement.
The official HMPPS rating is shown for context. It is not an input to these bands. HMIP inspection dates differ between prisons: a grade can be several years old. A flag is a prompt to look, not a finding of fault. Read the methodology.
