The mining and quarrying statistics show the amount and type of mining and quarrying in Denmark. The statistics have been made since 1973 but is only comparable since 2006.
The mining and quarrying statistics are a yearly measurement of extracted raw material types from land and from the sea floor stated in Cubic meters. The statistics are grouped by raw material types and by administrative regions and municipalities.
Data are annually collected from all extractors on land. The reported data are controlled for errors by comparing changes over time in the municipalities and for the totals for each resource category. Figures for raw materials extracted from the sea are controlled for errors in the same way.
There is great interest for the published figures on raw materials among the Regions, which use the statistics to make extraction plans. The statistics are also requested by municipalities, industry organizations, other public and private institutions, researchers, companies and the news media. The statistics are used in the compilation of the environmental-economic accounts in the national accounts.
Accuracy and reliability
The statistics are based on a census. 100 per cent of the population is covered. The overall accuracy of these statistics are therefore high.
Timeliness and punctuality
The Regions and The Nature Agency collects data and Statistics Denmark publishes the statistics within 1 month after receiving data. The statistics is normally published at the pre-announced time.
The statistics can be compared at the municipal level from 1980 onwards. The data has been largely unchanged over time. The quality or the reliability of the statistics is expected to be higher after 1990, because at that time a duty on the extraction of raw materials was introduced together with the control of all reports on extractions through the official channels. According to problems with implementation of the new municipality-reform in 2007 the data is considered to have a lower quality for 2007 than for 2006.
Accessibility and clarity
These statistics are published yearly in a Danish press release, at the same time as the tables are updated in the StatBank. In the StatBank, these statistics can be found under the subject Mining and quarrying in the following tabels RST01, RST3 og RST04. For further information, go to the subject page.
