Accuracy and reliability

Overall accuracy

In periods of business at the women's crisis centers, it may happen that some requests are not registered. The scope is not estimated. In addition, there are cases where the questionnaire is not filled in correctly, but there is no pattern in relation to when it is filled in incorrectly.

Sampling error

All women's crisis centers which are covered by §109 of the Act on Social Services have been asked to report, but reporting to the statistics is voluntary. Therefore, it might be that the centers that have voluntarily chosen to report do not reflect the overall population of women's crisis centers.

Non-sampling error

There might be duplicates without it being detected, since most of the people in the statistics are registered anonymously.

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

95 pct. of the reports are made without or with invalid social security numbers, which makes it difficult to troubleshoot the reports.

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.
