DRSG 1 / 2

Terms of Reference


  1. The Statistics Authority is carrying out a monitoring review to address the concern that producer bodies and users are faced with an increasing number of price indices and may be confused about which of these to select as the most appropriate deflator for their analysis by region, sector or industry. The rationale for the choice of deflator in official statistics publications is often unclear, and more advice to users is needed.
  2. The review will be conducted in two phases: the first phase will explore how deflators are used by producers of official statistics, and how choices are made and documented; the second phase will look further at quality and methodological issues, providing advice to a broad range of users as appropriate.
  3. An Outline for this work was endorsed at a meeting of the Authority’s Assessment Committee on 23 January.
  4. At the request of the Authority Chair, recognising the importance of this project, a small steering group will be set up to provide expert advice to the Monitoring team at key stages of the review. This group will be known as the Deflator Review Steering Group (DRSG).
