- Source: DVSA “Anonymised MOT tests and results”, data.gov.uk, under the Open Government Licence v3.0.
- Coverage: Full year 2024, test class 4 (cars), normal (initial) tests only.
- This covers cars tested in Norwich (DVSA's postcode_area field is the testing station's location, not the vehicle owner's home address).
- The age-adjusted figure is standardised to the national vehicle-age mix, so it isn't just reflecting whether this area's tested fleet happens to run older or newer than average.
