The aim of the international price comparison is to produce country-specific purchasing power parities. Purchasing power parity is an exchange rate by which the prices of commodity baskets in two countries are made equal in a common currency. The data collection is based on Regulation (EC) No 1445/2007 of the European Parliament and of the Council.Consumer prices are collected six times during three years for the international price comparison. The schedule for the next price survey is:2013 spring: Domestic appliances and other household commodities 2013 autumn: Motor vehicles, restaurants and hotels 2014 spring: Services 2014 autumn: Health care and furnishings 2015 spring: Food, beverages and tobacco 2015 autumn: Clothing and footwearIn addition, prices are collected every two years for machinery and equipment for the price comparison of investment commodities.
Price data are collected from retail outlets in the Helsinki, Vantaa and Espoo areas. The outlets vary randomly by survey group. They comprise a representative sample of stores of different sizes and types.Depending on the survey, altogether approximately 2,000 to 5,000 price observations are collected, in other words, around 4,000 to 10,000 prices per year. Around 200 price observations are collected for machinery and equipment. Statistics Finland’s statistical interviewers collect the prices either by visiting the stores or by telephone in connection with the collection of prices for services, for example. In addition, some data are collected by email.The obligation to provide data is based on the Statistics Act (280/2004).
The Statistics Act obliges Statistics Finland to treat the data as confidential and use them only for statistical and research purposes.The data are only published as index format statistics at product group level. The data concerning an individual outlet or product cannot be identified.
