Gera Active Life Score — Methodology
Full, reproducible formula behind GALS/100. Every number traces to a real Sport England Active Lives XLSX download. No modelling or extrapolation.
Formula
raw = activePct − inactivePct + 0.5 × fairlyActivePct
GALS = round( (raw − rawMin) / (rawMax − rawMin) × 100 )
clamped to [0, 100]
where:
activePct = % adults (16+) active (150+ min/week)
fairlyActivePct = % adults (16+) fairly active (30–149 min/week)
inactivePct = % adults (16+) inactive (<30 min/week)
rawMin, rawMax = min/max raw scores across all 317 English LAs
in the same survey yearEngland benchmark (November 2024–November 2025)
| Metric | England |
|---|---|
| Active (150+ min/week) | 64.5% |
| Fairly active (30–149 min/week) | 10.7% |
| Inactive (<30 min/week) | 24.7% |
| England GALS (benchmark) | 56 / 100 |
| Local authorities included | 317 |
Data source

Small-area data and suppression
Sport England's Active Lives small-area estimates at MSOA level are subject to statistical suppression where sample sizes are too small to produce reliable estimates. Where MSOA-level figures are suppressed, Gera falls back to the parent local-authority figure and renders an “insufficient data” notice rather than showing a fabricated or interpolated value. Local-authority-level data (used on this cluster) is not suppressed.
Frequently asked questions
- Where does the data come from?
- The Gera Active Life Score uses Sport England Active Lives Adult Survey data, Table 3 (Levels Local Authority), downloaded directly from the Sport England data-tables page as a no-login XLSX file. The file is published under the Open Government Licence v3.0. The November 2024–November 2025 edition was released in April 2026.
- How is the GALS computed?
- For each local authority: raw = activePct − inactivePct + 0.5 × fairlyActivePct, where all values are percentages from the Sport England data. GALS = round((raw − rawMin) / (rawMax − rawMin) × 100), capped to 0–100. rawMin and rawMax are the minimum and maximum raw scores across all 317 English LAs in the same survey year, so GALS is a relative ranking.
- Why add 0.5 × fairlyActivePct?
- Sport England defines "fairly active" as 30–149 minutes/week (half the 150-minute threshold for "active"). Weighting it at 0.5 gives credit for partial activity without double-counting it against the 150+ threshold. The weight is transparent and reproducible from the public source data.
- Why is GALS a relative (normalised) score?
- Normalising to 0–100 across all English LAs makes it immediately comparable — a score of 100 means the most active LA in England; 0 means the least active. It also means the scale is consistent across years (each year's rawMin/rawMax is re-calibrated from the current data).
- When is this data updated?
- Sport England publishes the Active Lives Adult Survey annually. Gera updates the GALS index with each new release. The current edition covers November 2024–November 2025 (released April 2026). The dateModified in the Dataset JSON-LD is 2026-06-20.
