Statistical processing

Source data

The primary data are collected from mainly public institutions, trade organizations, industry associations and private business enterprises.

• Milk and Dairy Products
• Eggs Production
• Slaughter Animals and Meat Production
• Fur Animal Production
• International Trade in Goods

Game information is provided by the Danish Environmental Protection Agency and DCE - National Center for the Environment and Energy's wildlife yield statistics.

Frequency of data collection

Monthly, quarterly and annual.

Data collection

Most data for the statistics come from other statistics in Statistics Denmark, among other things. statistics on slaughter, milk production, egg production and foreign trade statistics. The primary data are collected from mainly public institutions, trade organizations, industry associations and private business enterprises.

Data validation

Data validation takes place in several steps. Data has already been validated in the individual primary statistics, where the data received is checked for completeness and consistency as well as correlation with previous periods. For the purposes of these statistics, data are again checked for completeness and consistency as well as correlation with previous periods in aggregation and calculation of quantity and price indices as well as total values for animal agricultural products. In this context, it is possible to go back to the sources if needed.

Data compilation

Animal quantity and price indices are calculated in a hierarchical system where indices for the individual groups, natural milk, cattle, pigs, etc. are calculated. (Base index). Some of these groups e.g. pigs and cattle, have subgroups for which indexes are first calculated, which are then aggregated to the basic index for each group. The individual indices are calculated on the basis of the value of production by farmer in the base year. Subsequently, the detailed basic indexes are compared to the aggregated index. Here, cattle, pigs, sheep, horses, poultry and game are brought together for a total index of meat, which is then subsequently combined with milk, eggs and fur animals for a total index. The indices are weighted based on each group's percentage share of total value by farmer in the base year.

Adjustment

Data corrections are not made beyond what has already been described during data validation and data processing.
