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.



Final expenditure on housing is an important component of GDP. Its share of GDP for countries participating in Eurostat and OECD comparisons is usually between 8 and 12 per cent and tends to increase as GDP per capita rises. Although housing is a part of household consumption expenditure, it is not included in the cycle of price surveys for consumer goods and services described in Chapter 5. Instead it is covered by a special rent survey1 for which participating countries are not expected to collect data specifically but to extract them from existent statistical sources. The survey is organised by Eurostat and is held every year.2 Data are collected on the rents paid by tenants and on the rents imputed to owner-occupiers for a set of broadly-defined dwellings. Quantity and quality data on the housing stock are also collected.
