Every quarter approximately 500-600 prices are collected from a sample of relevant construction companies in Denmark. Prices are collected through an electronic reporting form via Business in Denmark. The collected prices are merged with relevant information from the Danish Buildings and Dwellings Register. The index is calculated by use of a hedonic regression where different information (characteristics of the single dwelling) is used.
Source data
The Producer Price Index for Construction of Dwellings is calculated on the basis of prices, reported by selected companies engaged in construction of one-family houses. The sample is selected using a top-down approach by turnover. The collected prices cover 30 to 40 pct. of the completed one-family houses i Denmark every quarter. Furthermore, the price information is enriched with information from the Danish Buildings and Dwellings Register. Currently, only data on one-family houses is collected.
Frequency of data collection
Quarterly.
Data collection
The prices are collected though an electronic reporting form, which is sent to the relevant contact within the selected companies. All further information is gathered from the Danish Buildings and Dwellings Register.
Data validation
The first validation of the price data happens when prices arrive to Statistics Denmark. Here they are tested for unusual developments and missing address information. Following this data is merged with administrative data. Unmatched data is treated manually and relevant information is applied to these observations. Also prices in relation to size of dwellings are checked.
Data compilation
