Accuracy and reliability

Overall accuracy

The results are based on ownership-relations obtained from administrative databases, combined with data validation of primarily the large and significant enterprises (100+ full-time employees) in Denmark.

The sources available for establishing ownership-relations are mainly the annual reports from the enterprises. This means that in case these annual reports for some reason are unavailable and/or insufficient, then there will be a risk of an underestimation of the number of enterprise groups in Denmark.

It is appraised that with the sources available, this statistic gives a fair and true view of enterprise groups in Denmark.

Sampling error

Not relevant for this statistic.

Non-sampling error

It is assumed, upon the completion of the data validation checks, that Enterprise Groups in Denmark contains a complete frame of the enterprise group relations in Denmark. This means that no enumeration or imputation of data are carried out.

As Enterprise groups in Denmark doesn't cover all activities, such as agriculture etc., then in the case that an enterprise actually are conducting activities in an industry that are not covered, but erroneously are placed in an activity that are covered (and at the same time have a valid ownership-relation), then this enterprise will be a part of the statistic. The significance of this, is appraised to be low. Likewise if an ownership relation has been terminated, but this information have not been removed from the source material, then an overestimation of the number of enterprise groups can conceivably occur. Enterprise groups in Denmark shows the ownership relations for enterprises/enterprise groups in Denmark. If non-active ownership-relations have been included and/or the opposite that active ownership relations have not been included, then this of course will influence the extent of enterprise groups, and distort the statistical value. However the impact of this is appraised to be very low and insignificant.

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.

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.
