The Gera Housing Stock Profile (GHSP) is a 0–100 index computed from four ONS Census 2021 Topic Summary tables (TS044 accommodation type, TS045 car availability, TS046 central heating, TS052 bedroom occupancy rating). Formula: GHSP = 0.30 × (detached+semi)% + 0.25 × (100 − overcrowded%) + 0.25 × mains-gas% + 0.20 × (100 − no-car%). A higher score indicates a local authority with more spacious housing, lower overcrowding, stronger mains-gas connection, and higher car availability. National England & Wales baseline: 74/100.
