Work Stoppages

As the statistics is based on a sample of major employees and employee organizations they do not provide complete coverage of the area. But it is assumed that the major part of working stoppages during the year is covered by the statistics.

Overall accuracy

It is not possible to calculate reliable measures on accuracy, as there are no comparable measurements. However, it is assumed that the statistics cover the main part of work stoppages during the year.

Sampling error

Can not be calculated exactly.

Non-sampling error

Can not be calculated exactly.

Quality management

Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.

Quality assurance

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

Quality assessment

As the statistics is based on a sample of major employees and employee organizations they do not provide complete coverage of the area. But it is assumed that the major part of working stoppages during the year is covered by the statistics. The statistics only cover employees organized in an employer organization and public employers. Furthermore, the statistics hardly covers all working stoppages. Likewise, it is not curtain that all local work stoppages are reported to the respective employer organizations.

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.

Data revision practice

Normally the published figures are not revised. If errors are detected in the published figures, these will, however, be corrected.
