Old Age Pension and Disability Pension

All recipients of old-age pension and disability pension under the legislation covered, both residents in Denmark and abroad based on Udbetaling Danmarks register. There may be errors and duplicates in the registry that are removed, but it affects less than 0.01 per cent. of the persons to whom money is paid.

Overall accuracy

The data source for these statistics is an administrative register with full coverage of old-age pension and disability pension. There may be errors in Udbetaling Danmark's register, which is not detected by Statistics Denmark. In those cases, the error is included in the statistics as well as in the payout itself. It is estimated that the total error is small (for less than 0.01 per cent of the population).

Sampling error

The sampling error is zero.

Non-sampling error

The statistics are based on data from an administrative registerprovided by Udbetaling Danmark. There is a risk of under-coverage, but the number and distribution of pensioners is on par with previous years. After error detection, less than 0.01 per cent is excluded. of data. In January 2021 the total amount is calculated from the other amounts according to the same method for which the variables were generated by KMD previously.

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

Coverage

All recipients of old-age pension and disability pension under the legislation covered, both residents in Denmark and abroad.

Quality of variables

The data stems from administrative registers with full population coverage. Apart from a very minor risk of erroneous entries in the register, there is no statistical uncertainty.

The overall accuracy is very good as the data source is an administrative (payment) record with full coverage. The material is tested mechanically. Individual errors are corrected manually. If there are systematic errors a new data extraction is ordered from the data provider.

There is no imputation or calculation of the register data. It is estimated that the overall risk of errors is negligible.

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.
