Triennial and Quinquennial Reviews

The need to review surveys is a requirement of the Prime Minister's instructions for controlling government statistical surveys.

These instructions underline the need to review all regular surveys of business and local authorities with an emphasis especially on:

  • the need for the information (evaluating the reason for conducting the survey)

  • the conduct of the survey

  • costs

  • respondent's views

  • users' views

  • options for change

There are two types of review, depending on the frequency of the survey.

  • Surveys that are conducted on a monthly or quarterly basis are subject to review every three years (Triennial Review)

  • Surveys that are conducted less frequently than quarterly, for example, annual inquiries, are subject to review every five years (Quinquennial Review)
