Home page - 19-th meeting of the Ottawa Group

The Ottawa Group on Price Indices is a city group established by the United Nations Statistical Commission in 1994. It provides an international forum for experts in national statistical offices, international organizations and research institutions to discuss conceptual, methodological and practical issues related to price indices. An interesting article on the history of the Ottawa Group and its contributions to CPI methodology is available in English on the “OpenEdition Journals” website.

The Group is concerned mainly with the consumer price index (CPI) but also discusses other price indices and issues that are relevant to price statistics in general. The objective of the Group is to support the development and implementation of sound methods and best practices in national statistical offices for the compilation of price indices. Without avoiding theoretical aspects, the focus of the Group is on applied research and the development of best practices.

The Ottawa Group meets every second year. The meetings are attended by price index experts from national statistical offices, international organisations and research institutions. The most visible output of the Ottawa Group are the papers (available for download on the group’s official website) presented and discussed at the meetings (links are available on the group’s official website).

The 19th meeting took place on 13–15 May 2026 in Warsaw and was hosted by the Central Statistical Office, the National Bank of Poland (NBP), and the Warsaw School of Economics – see the meeting report (PDF, 3.71 MB).

The next meeting of the Ottawa Group will be held in May 2028 in Pretoria, South Africa.
