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

The quality of the statistics is linked to the quality of the sources included in it. Thisi is especially concerning data from administrative records that may be subject to uncertainty. Requirements for reporting to the registry were statutory from 2015 and a gradual improvement of the contents of the register due to better reporting, due to higher registry functionality, more stringent legal requirements for the reports and a more accurate description of the desired content of the reports is expected. In some cases, there may be errors in individual industries industry placement, which is continuously quality assured by Statistics Denmark's Statistical Business Register. These minor uncertainties, however, have limited importance at an aggregated level.

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
