Quarterly national accounts (discontinued)

The quarterly national accounts are compiled using a number of primary statistics. Inaccuracy in these primary statistics as well as the adjustment of the statistics to conform to the national account framework will affect the reliability. However, the juxtaposition in the framework of the national accounts will contribute to reduce the inaccuracy.

Overall accuracy

Based on past experience the uncertainty of GDP growth is assessed to generally +/- 0.5 percentage points. The latest figures for revisions of the quarterly GDP growth rates can be found here (available only in Danish ): Revisioner af det kvartalsvise nationalregnskab.

Sampling error

Non-sampling error

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.

The ESA 2010 regulation requires Eurostat to undertake quality assessments of reported data in accordance with the ESA transmission program. The starting point for this is in the individual nation’s own quality reports, which are not independently published by Eurostat. These reports are prepared annually.

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

Quarterly national accounts are compiled in a number of versions for a quarter. Quarterly national accounts and sector accounts are consistent with the latest final annual accounts which are available approximately 3 years after the calendar year. A calendar over the planned releases for National Accounts is available (only in Danish) at https://dst.dk/nationalregnskab.
