In connection with the creation of the population, it should be noted that differences in the municipal case management systems imply that the municipalities do not register information about vulnerable children and young persons in the exact same way and systematically. This may result in inconsistency from one municipality to the next as to exactly which children and young persons to include in the population. We do not know the size of this source of error, nor do we know how much it affects the accuracy of the statistics. Furthermore, you should note that the statistical population also includes children and young persons with physical disabilities who – due to their disabilities – have been removed from parental care or have support measures. We do not currently know the size of this group.
Overall accuracy
The internal registers used to compile this set of statistics have all been estimated to be of high accuracy, which is why this set of statistics is estimated to be of the same high accuracy.

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
At an overall level, the quality is estimated to be good as these statistics comply with the delimitations and census methods of the source statistics. We currently process psychiatric data in the same way as somatic data, and we will be working with the quality in this regard in 2019. For further details, see the separate statistical domain: Vulnerable children and young persons Visits to physicians etc. Hospitalisation rates
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
