Announcements of forced sales of real property

The forced sales of real property statistics provide a monthly total count of the number of announced forced sales of real property in the Danish Official Gazette with unique owners within the month in question. In this way it is ensured that major fluctuations in the statistics are minimised. The primary purpose of this set of statistics is to be informative regarding trends and it is not an assessment of the number of forced sales actually carried out.

Overall accuracy

By screening out announced forced sales with the same owner, it is ensured that major fluctuations are minimised. There may be cases where one owner owns several properties, e.g. a single-family house, an owner-occupied flat, a summer house and a business property which are all subjected to a forced sale and accordingly announced in the Danish Official Gazette. There may also be cases where an enterprise owns many properties. If each announced forced sale is included in the count, major fluctuations could potentially occur and the statistics would not give a true and fair view.

All forced sales are announced in the Danish Official Gazette no later than 14 days before the public sale takes place. Right up to the forced sale takes place, the owner of the property may seek to prevent the sale by paying the creditor. In that case, the public auction will be cancelled. This means that there is a difference between an announced and an enforced forced sale.

Sampling error

The statistic is a total statement for announcements of forced sales of real property.

Non-sampling error

There is a risk of register errors as well as of duplicates (see Data validation).

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

With the exception of changes in the geographical break-down, including the Structural reform in 2007, the statistics have been comparable since 1979. This makes these statistics interesting in terms of comparing the development with other macro-economic indicators across several economic cycles. Furthermore, the statistics are not subject to any bias due to the counting unit combined with the fact that a total assessment is concerned. However, the quality of the statistics depends on the accuracy of the information entered in the forced sales advertisements in the Danish Official Gazette.

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

Only final figures are published. However, the seasonally adjusted figures are revised back in time on an ongoing basis if the seasonal pattern changes.
