Comparability

Comparability - geographical

The Account Statistics for Aquaculture is the basis for Denmark's submission of statistics to EU's Directorate-General for Maritime Affairs and Fisheries. Statistics for the member countries is published by the Scientific, Technical and Economic Committee for Fisheries (STECF) in the report Economic Performance of the EU Aquaculture Sector. The EU statistics cannot be compared directly with the Danish national statistics. Variables in the EU statistics are more aggregated, and the statistical groups are segmented differently from the Danish statistics.

Comparability over time

The statistics in the current form is comparable back to 2017.

There are also two older time series: One covers the years 2009 to 2020 where the segmentation of land based farms was different from the current series. One covers the years 2004 to 2013 where the calculation of Net Profit is different from the later series. E.g.. depreciations were not included.

Coherence - cross domain

The Danish Fisheries Agency shows production volume and production values on their homepage and in StatBank Denmark.

The Danish Fisheries Agency statistics is not directly comparable with the Account Statistics as it does not show internal sales between different farms in the firms. Furthermore, the population consists of both commercial and noncommercial farms and they cover the calendar year and not the fiscal year.

Coherence - internal

An important task of the data management is to ensure consistence between units in the reported accounts and the units based on the register entities. Consistency is accomplished by adjusting register based units to the real world units, and to split up company accounts into farm unit accounts.
