Accredited official statistics status
Accredited official statistics status means that our statistics meet the highest standards of trustworthiness, quality and public value, and it is our responsibility to maintain compliance with these standards.
These statistics were first designated as accredited official statistics by the UK Statistics Authority in assessment report number 4 in July 2009. The statistics were reassessed in reported number 258 in July 2013.
The designation of reported road casualties statistics as accredited official statistics was further confirmed in August 2019 following a compliance check against the Code of Practice for Statistics by the Office for Statistics Regulation.
In 2024, a short review was carried out by the Office for Statistics Regulation, leading to the accreditation of the severity adjusted data which form part of the casualty statistics.
Changes to these statistics
Since the latest review by the Office for Statistics Regulation in 2019, we have continued to comply with the Code of Practice for Statistics, and have:
- developed a methodology with the ONS Methodology Advisory Service to adjust for the discontinuity in severity reporting as detailed in the 2017 interim report and in the 2018 final report leading to accreditation of the adjusted figures in 2024
- started analysing the impact of the introduction of online reporting of road accidents in road casualty statistical releases
- innovated our dissemination methods by developing several tools for users to access and query the road safety data by producing bespoke tables
- added more contextual commentary on other road safety data sources to the road casualty statistical releases and a series of new topical factsheets, including on areas of emerging interest such as e-scooter casualties
