3.1. Data description | |||
HPIs give comparable measures for dwellings prices. They are calculated according to a harmonised approach and a single set of definitions. The House Price Index (HPI) is a quarterly indicator that measures the changes in the dwellings transaction prices that households acquire on the market. Prices include land value. The data on the HPI is provided in the form of an index number comprising two sub-indices: Purchases of newly built dwellings and Purchases of existing dwellings. |
|||
3.2. Classification system | |||
The index numbers are conform to the classification details required by the Regulation. |
|||
3.3. Coverage - sector | |||
Household Sector (ESA 2010 sector S.14). |
|||
3.4. Statistical concepts and definitions | |||
The HPI covers all transactions of dwellings made by households regardless of its final use. This index thus covers not only the transactions that are new to the household sector but also all that are traded between households. Index figures for the purchase of the dwellings are compiled on the basis of full transaction prices which are collected through the Public Notaries Offices (actual transaction prices recorded in the contract signed in front of the public notary, prices established between the seller and buyer of the dwelling). All of the transactions of dwellings are registered and authorized by public notaries. All the practicing notaries are included in the National Union of Notaries Public from Romania, a professional organization with legal personality. Transaction prices include the value of land. The HPI is a fixed base Laspeyres price index. HPI data are published in the form of index numbers (current reference year: 2015). Data is sent to Eurostat in base 2015=100. The HPI is weighted by the value of dwelling transactions (flats and houses) sector and by location (flat in Bucharest, flats in rest of the country, house in urban area and house in rural area). |
|||
