Ottawa Group

International Working Group On Price Indices



Picture: Ottawa membersThe Ottawa Group on price indices was formed in 1994 to provide a forum for specialists to share their experiences and discuss research on crucial problems of measuring price change. Without avoiding theoretical issues, the focus of the Group is on applied research, particularly though not exclusively in the area of consumer price indices. The Group examines advantages and disadvantages of various concepts, methods and procedures in the context of realistic operational environments, supported by concrete examples whenever possible. Participants are specialists and practitioners who work for, or are advisers to, statistical agencies in different countries or international organizations. The Group meets about every 2 years.


This website hosts all papers that have been presented at Ottawa Group meetings providing a resource for price statisticians. These papers are available in the Papers link on the left hand navigator by author, title and organisation or via the Meetings link. Further resources on price indices can be found in the IWGPS: Consumer Price Index Manual: Theory and Practice (2004).
