The OECD, Eurostat, and 47 participating countries work together in establishing purchasing power parities, or PPPs, in order to compare the price and volume levels of the GDPs. This programme is called the Eurostat-OECD PPP Programme. The manual gives a complete, detailed and up-to-date description of the functioning of the programme. This includes its organisation, the various surveys carried out by participating countries and the ways PPPs are calculated and disseminated. It also provides guidance on the use of PPPs.


Presentation and dissemination of results

The chapter describes how Eurostat and the OECD present and disseminate the results of their comparisons. It also describes how Eurostat and the OECD update the disseminated results of the latest comparison before the results of the next comparison become available. In addition, the chapter explains the revision policy followed by Eurostat and the OECD with respect to results already disseminated for a comparison and subsequent revisions made by participating countries to their estimates of GDP for the year to which the comparison refers. This is an important consideration as such revisions can change the relativities originally established between countries. The chapter concludes by clarifying the access policy of the two organisations with regard to results and underlying basic data that are not in the public domain.
