What the Office for Statistics Regulation wrote

“While the claims in the promotional material cited the sources for the figures quoted, I consider that improvements could have been made to aid transparency and better support users.”

“I consider, however, that it would be challenging for a reader to unpick this detailed document to find and understand the data and calculations used to support this claim, and that it would not be reasonable to expect people who read the leaflet to do so.”

“In short, I do not consider that the presentation of this analysis in the leaflet fully aligns with our expectations for Intelligent Transparency.”

“Transport for Wales, in conjunction with Welsh Government, should consider how it can make improvements to data and statistics on the implementation of the 20mph speed limit, including considering the accessibility of data and supporting information.”
