Eurostat, the OECD 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 and the methodological manual provides a detailed description of it. The manual has three aims: first, to explain to practitioners in Eurostat, the OECD and the national statistical institutes how PPPs are compiled; second, to enable practitioners to advise on the use and interpretation of results to users; and third, to provide a point of reference accessible to teachers, students and other members of the general public interested in PPPs and related statistics.
