Sub-annual investment statistics take into consideration the establishing of new tangible assets, the purchasing of new assets; the additions, alterations, improvements and renovations of existing assets, including all related expenses incurred until putting the assets into operation.
Sub-annual investment data are based on full-scope (all enterprises with more than 49 employees, and all water management associations and budgetary and social security organisations irrespective of the number of employees) and representative observations (enterprises with 5–49 employees) as well as expert estimations (of dwelling investment mostly). The representative observation is based on stratified sampling. The method of grossing up is the multiplication of the sample mean by the sample size for the various strata.
The estimation of dwelling investment is based on the floorspace of the new dwellings brought into use. Value data are calculated by the average price per square metre. For the estimation of other construction and reconstruction (holiday house, garage, fence, etc.) the trends of previous years are taken into consideration.
Performance value is the performance of investments according to the contract, regardless whether the countervalue has been settled or not. The value comprises non-deductible VAT.
Data suppliers may modify data of their own subsequently, therefore the data may be corrected retrospectively. Accordingly, the data may differ from the figures of former publications.
