STATS19 DATA LAB · GREAT BRITAIN
Police-reported injury collisions in Great Britain · geographic history 2016–2025 · record analysis 2021–2025
Road-mix adjustment does not remove all geographic confounding.
Charts displayed; exact values remain available with each chart.
GEOGRAPHY · ROAD MIX · PERSISTENCE
Compare recorded injury collisions with the number expected for the same mileage across motorways, A roads and minor roads.
Selected comparison: Road mix & geographic persistence · 2025
Selected comparison: English regions, Scotland & Wales · Road-mix adjusted · observed / expected
The common panel excludes any region containing authority reporting warnings or unknown road classes in this period. Published joint road-category mileage supplies every regional denominator. Rates describe collision locations; they do not measure residence or postcode insurance risk.
Derived descriptive rate
Outcome: Reported injury collisions
Adjustment: Raw rate or indirect road-mix O/E against the fixed GB 2022–2023 reference
Interpretation limit: Includes injury collisions involving only non-motor road users over a motor-mile denominator. This is a contextual road-exposure rate, not matched motor-involved collision frequency, insured claim frequency or fault.
Observed / expected · fixed GB 2022–2023 reference · darker means higher recorded value
| Measure | North East | North West |
|---|---|---|
| Raw per 100,000 miles | 0.021 | 0.0258 |
| Raw relative to GB reference | 0.654× | 0.802× |
| Road-mix adjusted O/E | 0.573 | 0.926 |

| Conditional 95% O/E interval | 0.552–0.594 | 0.908–0.945 |
| Status | Available | Available |
O/E = observed collisions ÷ expected collisions. A value of 1 matches the fixed GB reference after allowing for these three road categories. Higher values are descriptive, not causal.

The denominator and fixed reference remain consistent across supported years. Gaps are unavailable evidence. Authority persistence is untested with one eligible year.

Few broad geographies and two later years limit the strength of this evidence. Road mix, reporting and unmeasured traffic differences remain possible explanations.
