Purpose and Brief History

For 33 years, representatives from national statistical agencies have met annually to address selected problems in statistical methods. The Voorburg Group derives its name from the city in Netherlands where it first met in 1987. The experience with the Voorburg Group has shown that the international community can benefit greatly from such a process. These informal consultative groups are an innovative way to use country resources to improve and speed up the international standards development process.

The mission of the Voorburg Group on Services Statistics is to establish and maintain an internationally comparable methodology for measuring output and producer price indexes for the service industries. We focus on the development of concepts and methods, the sharing of best practices, and identification of classification needs. The Voorburg Group has contributed over the years to building up and sharing a considerable and growing body of knowledge of Service Sector Statistics. It has prompted international cooperation in the development of standards and has assisted in resolving statistical and measurement challenges in the Service Sector.

Voorburg Group on Service Statistics Website:

The Voorburg Group's Strategic Plan 2017-2021 focuses on five major objectives:

  • - Updating its best practices to account for the rapidly changing economy and its impact on statistical measurement practices;
  • - Producing guidance papers on cross-cutting methodological issues;
  • - Providing a forum for information exchange on best practices and emerging issues through both formal meetings and
      active collaboration throughout the year;
  • - Making VG documentation more accessible and up-to-date; and
  • - Enhancing the Group's understanding of the concepts and requirements of National Accounts in measurement of real output
       and productivity in the services industries.

The Group maintains a permanent website, currently hosted by Statistics Canada, on which all of the Group's outputs can be found. At this site you can search for all the papers presented at every meeting, view the agenda and participants for all meetings and get the latest Voorburg Group News.

The website includes three primary types of papers: mini-presentation papers, sector papers, and revisited sector papers.

The mini-presentation papers for prices, turnover, and classification present specific country's experience or practice on a given industry or part of an industry and are used to facilitate the discussion and exchange of knowledge and expertise.

The sector papers and revisited papers are the codification of the best practices in the development of prices, turnover, and classification for a given industry. Both the revisited papers and sector papers are considered as the "final" outcome of the Voorburg Group's development work for a particular sector. As industries and products change, the Group has updated previous sector papers so it is always good to consult the most recent version for a particular sector.

The Reference Documents tab on the website contains the Voorburg Group's Strategic Plan, the Content Development Framework that guides the development of Sector Papers as well as the development of new Guidance Papers on cross-cutting methodological issues, an updated Glossary, as well as international recommendations and manuals on national accounting and price measurement.
