Housing Benefits

The statistics are based on administrative registers of housing benefits, but errors and duplicates may occur in the register. Invalid data and duplicates are removed (less than 0.01 pct.). The housing benefit amounts are overestimated compared to reality, since months with less than a full month's housing eligibility are included as a full month in the statistics. Only final figures are published.

Overall accuracy

The statistics are based on the administrative register of housing assistance (Udbetaling Danmark). After excluding invalid data, the frame population is about 99.9 per cent. of the target population. The amounts in the statistics are a little overestimated compared to the reality, as the statistics covers amounts for whole months even though the housing benefit in some cases is awarded for a shorter period. If the housing benefit is reduced due to the cash benefit ceiling, the amount is calculated based on the stated reduction amount in the register. There might occur errors in the 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.

Sampling error

Not relevant for these statistics.

Non-sampling error

The statistics are based on the administrative register on housing benefits in Udbetaling Denmark. After excluding invalid data, the population of the statistics consist of approximately 99.9 pct. of the target population. In the statistics, housing benefits are calculated for entire months. Households which are only eligible for housing benefit for part of the month, the amount paid in the statistics is therefore an overestimate of the reality. Reduction in housing benefit, due to the upper threshold of total cash benefit, introduces a small risk of calculation errors.

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

The overall quality is good, since the source of the data is the administrative payment register with full coverage.

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.
