Dear Stephanie,   

Thank you for your letter requesting a temporary suspension for the accredited official statistics status for outputs based on the 2024-2025 National Survey for Wales data. This request is due to a smaller than expected achieved sample size for the survey in 2024-25 which will impact on the quality of estimates at lower levels.  

Based on your investigations, we agree with your request to suspend the accreditation of the National Survey for Wales statistics. We understand that data derived from the National Survey for Wales are used to inform national well-being indicators in Wales. Therefore, please do consider any potential quality impacts on other statistical outputs that rely on this data, such as the annual Wellbeing of Wales statistics. 

We welcome your plans to publish the release of 2024-2025 results as official statistics in development and your commitment to be transparent in your guidance for users on how the data should be used and interpreted. We also support your future ambition to increase the achieved sample size by moving from a telephone-first to an online-first approach. 

My team will be happy to engage with you about the most appropriate timing for a review of these statistics. This will be with a view to reinstating accreditation once you feel assured that they fully comply with the Code of Practice for Statistics.    

Yours sincerely,  

Ed Humpherson
