NATIONAL FEATURE REGISTRY · EXPANSION E4–E7 · EW-V3
Explore public-data features across all 35,672 LSOAs. Decile boundaries are fixed nationally, so every local view uses the same scale.
FEATURE PREPARATION · COLLISION EVIDENCE IS A SEPARATE STAGE
E4–E7 adds air quality, a supporting summer-days normal, tagged speed limits and authority insolvency context. Four crime measures and two speed shares have diagnostic raw values with national bands withheld. Coverage gates and source-access gaps remain explicit.
The >25°C climate normal and assessed 2025 air values use road weights. Exact ≥25°C and ≥30°C daily thresholds await registered source access. Crime reporting gaps and contradictory records prevent national crime ranking.
Speed-limit shares require at least 95% classified road length. Only 1,547 areas qualify, so national speed bands are withheld; unknown lengths and bounds are retained. Bankruptcy and insolvency use shared authority rates. No nationwide walking or cycling flow deciles are inferred from sample counters.
Complete coverage describes the calculation. Census commuting is pandemic-era resident context; connectivity is modelled accessibility. Neither measures actual pedestrian or cyclist flows. The new deciles are research features, with no demonstrated accident or insurer-claims effect.
This milestone provides research inputs, not validated accident-risk indices. The Phase 3 national collision–mileage panel is available with explicit exposure-quality gates. The existing regional mileage pilot does not determine these bands.
ONE SCALE ACROSS BOTH COUNTRIES
Residents aged 16+. Not age-adjusted; age composition is a separate control.
D1 = lowest feature values; D10 = highest. A higher feature decile does not automatically mean higher accident risk. Ties stay together, so band sizes can differ.

FROZEN BEFORE NEW OUTCOME MODELLING
Each LSOA has equal weight. Eligibility uses only source coverage and applicability. Identical values share a band, unavailable values stay missing, and regional views never rerank areas.
Original combined bands remain available if later modelling supports merging neighbouring categories.
Develop on 2022–2023, use 2024 for selection and treat 2025 assessment as exploratory because earlier studies inspected it. Hold out whole English regions and Wales to test geographical transfer.
A fresh period must pass an outcome-access audit before independent confirmation. Insurer claims testing remains separate.
This is a retrospective registry: Census Day 2021, roads April 2026 and frost climatology 1991–2020. The 2025 air and insolvency sources were published in 2026; crime runs through August 2026 and OSM limits are from October 2026. These are retrospective context for earlier accident years. Connectivity has a Q4 2024 workbook reference, mixed source vintages and a 29 September 2025 publication date. These national bands were frozen on 12 October 2026. Publication dates differ from observation dates. These inputs cannot all be claimed available at a 2022 forecast origin.
OS roads include mapped private and restricted roads. Length shares and junction density are physical context, not motor-mile exposure. Sinuosity uses generalised geometry. Frost is a prior climate normal, not realised annual weather or measured carriageway ice.
Later collision models need matched all-motor miles and must assess whether features also influence exposure estimation. Location-of-collision features do not establish policyholder-residence risk or causal effects.
The protocol compares a baseline with continuous, smooth and categorical feature alternatives using the same observations and offsets. It records assessment metrics, geographical checks and proposed promotion gates.
