Statistical processing

Source data

Data is retrieved from several registers: The Integrated Agricultural Control System (IACS), which is a register of farmers' applications for area support with the number of hectares of land divided into fields. The register has a record of the fields used for agricultural activity with crops. The GLR is maintained by the Danish Agency for Green Land Redevelopment and Aquatic Environment. The land is registered in the Land Registry, which is administered by the Danish Geodata Agency, as is the Owner Register, which describes ownership of real estate. Information about the owners is retrieved from the Central Personal Register (CPR), and in addition there is the Central Business Register (CVR), address registers, and finally Eurostat's Group Register (EGR).

Frequency of data collection

Annual.

Data collection

Data for the statistics is collected via a system-to-system solution.

Data validation

There is no data validation since the register information is assumed to be reliable.

Data compilation

The starting point for the statistics is the GLR, i.e. farmers' applications for area support. The registered fields are linked to the Cadastre, BFE_nr. If, after the GIS overlap analysis, there are individual areas of less than 1,000 square meters that cannot be matched, these areas are omitted in order not to create further uncertainty. If the field has multiple owners, the land is distributed proportionally with ownership shares. The nationality of the owners can be determined via the CPR or CVR. For companies, ownership of the company and possibly its owners is examined to identify ownership through legal or real owner. The search is first for the real owner, and then the legal owner. If only legal owners are registered in the CVR, it is examined whether the company is registered in the European Group Register (EGR) of multinational companies. The register is updated 14 months after the end of the year, so that for the current statistical year the same EGR basis is used as for the previous year. If there are multiple owners of a company, ownership of the land is distributed proportionally with ownership shares. If no foreign ownership has been identified in the company, the ownership is determined to be Danish. For owners whose nationality is unknown, a category "unknown nationality" has been created. For persons with dual citizenship, citizenship is determined to be Danish, if this is one of them.

When calculating the agricultural area by country, there is uncertainty because the ownership shares of a piece of agricultural land do not always add up to 100. Example: A piece of land has a German owner with a share of 20 percent and a Danish owner with a share of 60 percent. This means that 20 percent of the area cannot be determined. In such a case, the ownership shares are adjusted proportionally by a factor of 100/(20+60)=1.25, so that the German share becomes 201.25=25 and the Danish share 601.25=75. Such cases amount to 1,304 ha in 2022, 283 ha in 2023 and 200 ha in 2024. This is less than 1 per mille of the total agricultural area for all three years.
