It is compulsory for dairies to register the milk weighed on the dairies and the dairy production. This is the basis for settlement to farmers, which is therefore expected to be measured accurately. Information on the milk weighed on each farm must be reported to the Central Animal Register, as ownes of the Ministry of Environment and Food. The calculation of prices and values is based both on actual a conto prices and partly on estimates of the anticipated after payment, which is only realized after the end of the dairy year and can thus cause uncertainty about the accrual. The estimate of the consumption of milk by producers and consumption for feed is estimated after consultation with the Dairy Association.

Overall accuracy
Data on the amount of milk deviled to the dairy has a high quality since it is mandatory for dairies to register this, but it also provides the basis for the settlement to the milk supplier (farmer). Production on dairies is statutory to register. The calculation of prices and values is based both on actual a conto prices and partly on estimates of the anticipated down payment paid by the cooperatives and only after the end of the dairy year and can thus cause uncertainty about the accrual. The calculation of milk consumption by producers to 3.024 million kilo from 2020 and consumption for feed of 75 million kilo per years are estimated after consultation with the Dairy Association
Sampling error
Not relevant for this statistics.
Non-sampling error
There is an uncertainty in the estimate of milk consumption in the producers. The last 3 months of data will always be preliminary, as there are some dairies who have a long time to report final figures on dairy production.
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 calculation of the amount of milk weighed on dairies is of high quality as it is compulsory for dairies to register this and report it to the central livestock register, as owner of the Ministry of Environment and Food. The information is also the basis for the settlement to the milk supplier (farmer).
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
The figures are revised for 2018 in November 2018. There is a minor difference between provisional and final figures of under ½ pct. The figures for 2016 and the first half of 2017 were revised in October 2017 because the method used at that time was not optimal with regard to the monthly milk inventory.
