Accuracy and reliability

Overall accuracy

Data on the eggs weighed in the packing centers has a high quality both regarding the type of egg and the amount of these, as it is mandatory for egg producers to report this data. The same applies to the number of hatching eggs, as this information is statutory to register and report to Food Enforcement.

The estimation of eggs for own consumption and sales directly to consumers is estimated - and there is some uncertainty as the average number of hens and thus eggs is unknown. This consumption is set at 12 million. and are listed in the table so that users can choose to use the numbers without this estimate. The estimate may be too high, as 10 per cent. of the total production is considered to be high.

Sampling error

Not relevant for this statistics.

Non-sampling error

The production of eggs does not cover eggs of private individuals outside the agricultural sector. The hatching eggs inventory only covers hatching eggs on hatcheries. There is an uncertainty in the estimate of consumption of eggs by the producers and sale of eggs directly to consumers, as we do not know this uncertainty, the figure is entered separately in the statistical bank. . The estimate may be too high -13 percent of total production is considered to be high consumption and direct sales to consumers.

It is not possible to check whether the calculation of hatching eggs at the end of the month falls in the correct month, but the starting point is that this happens. The same applies to the weighed eggs in the packing rooms

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 inventory of eggs weighed in on the egg packing centers is good, as well as the price and value of the different egg types. The largest uncertainty is the estimated consumption of egg producers and, in particular, sales directly to consumers. This uncertainty transfers something to the calculation of the total production of eggs both quantity and value, so data is shown both without and with own consumption and direct sales to consumers.

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.
