Accuracy and reliability

Overall accuracy

The statistics are based on primary data that has been edited in the process of producing other statistics, and the resulting quality is therefore regarded as being good. For an assessment of the overall accuracy, refer to the documentations of statistics for Establishment-related Business Statistics, the Register-based Labour Force Statistics, Educational Attainment, and Business Demography.

Sampling error

Not relevant for these statistics.

Non-sampling error

For an assessment of the non-sampling errors, refer to the documentations of statistics for Establishment-related Business Statistics, the Register-based Labour Force Statistics, Educational Attainment, and Business Demography.

Private as well as public employers are obliged to report data to e-Income relating to the workplace at which the job takes place. With respect to the municipal sector, the data reports are particularly inadequate for 2008-2010. Against this background, it has been necessary for Statistics Denmark to conduct major rectifications of the data with respect to distributing the statistics by geographic areas and detailed activities. However, the quality will never be the same unless the necessary data reports had been rectified by the employer. The measure sources of inaccuracy are, especially linked to the distribution of jobs in the municipal sector classified by activity. There are, in particularly, uncertainty with regard to whether a person is employed in administration or not, whether a person is employed in teaching in the primary and lower secondary school or in teaching not further specified, or whether a person is working in a nursing home or within home help. There is also uncertainty with regard to the distribution of jobs by municipality of the workplace.

Quality management

Statistics Denmark follows the recommendations on the organisation and management of quality set out in the Code of Practice for European Statistics and the accompanying implementation model, the Quality Assurance Framework. Read more about these on the page Quality in official statistics.

Quality management is supported by common principles, guidelines and managerial responsibility for quality in statistical products and processes. The aim is to ensure a systematic and consistent approach to quality across the entire statistical production.

Quality assurance

Quality assurance at Statistics Denmark is integrated into the statistical production processes and is carried out in accordance with the principles of the Code of Practice for European Statistics. Read more on the page Quality in official statistics.

Quality assurance includes the continuous use of standardised procedures, documentation in line with international standards and internal controls related to data collection, data processing and dissemination. Experience gained from production is continuously used to identify needs for adjustments and improvements.

Quality assessment

The statistics is based on edited data from Statistics Denmark's central registers that form the bases of official statistics. No actual measurement of the quality and no calculations on measures of accuracy has been performed. For an assessment of total quality, refer to the documentations of statistics for Establishment-related Business Statistics, the Register-based Labour Force Statistics, Educational Attainment, and Business Demography.

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.
