Accuracy and reliability

Overall accuracy

The registration in the register of both listed buildings and ancient monuments is done manually and with a certain delay in relation to the decision of conservation. There may be overlap between ancient monuments and listed buildings, especially in the medieval ruins and -villages and listed buildings on them, which means that there may be a listed building on a protected archaeological sites, for example by a manor house built on a mound i.e. there are two different recovery periods on the same site.

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 overall accuracy is high as there is data from national registers.

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
