Introduction

The Office for Statistics Regulation (OSR) is the independent regulatory arm of the UK Statistics Authority (known as the Authority). Our vision is that statistics should serve the public good; one way we achieve this is through our casework.

This report draws together our casework from 1 April 2022 to 31 March 2023 (2022/23). It focuses on the issues and themes in the 372 pieces of casework we have investigated.

The casework annual report is aimed at anyone with an interest in the work of OSR or anyone interested in how official statistics are used. It highlights key case studies from 2022/23 and, where relevant, reflects on previous years.

This report is supported by three annexes:

• Annex A – ‘Casework Summary April 2022 to March 2023’ provides management information related to our casework. For this year we have also provided historical management information from 2019 onwards, and also included our underpinning assumptions and interpretation of the data,
• Annex B – ‘Statement of voluntary compliance’ is a statement of our compliance with the Code of Practice for Statistics and
• Annex C – ‘Parliamentary discussions of casework’ provides examples of where our casework has been referenced in parliamentary debate.
