Statistical processing

Source data

The five regions collect figures for all extractors and pass them to Statistics Denmark. Figures concerning the extraction of raw materials from the sea are received from the Ministry of the Environment.

Frequency of data collection

Data is collected annually.

Data collection

Data on mining and quarrying on land is collected by The Danish Regions and transferred to Statistics Denmark through a system to system solution.

Data on the extraction of raw materials from the sea is received and treated by the Ministry of the Environment.

Data validation

Reported data is subject to error checking by Statistics Denmark. The individual reporter's extraction for the current period is reviewed. If the reported extraction deviates significantly from expectations, the reporter is contacted to verify the accuracy of the submitted data. It is assumed that not all errors in the reports are detected during the error-checking process, and therefore the statistics may carry a certain degree of uncertainty related to misreporting. The error-checking process focuses specifically on the reports that have the greatest impact on the statistics, and under normal circumstances, the uncertainty associated with misreporting is considered to be quite small.

Data compilation

Mining and quarrying statistics are a census. Data is being validated and figures are published at an municipality, regional and national level.
