Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
Statistics on the production of eggs for consumption are collected in frame of the annual survey on poultry production. Figures represent the number of laying hens and the number of eggs for consumption produced in agricultural holdings keeping at least 5,000 laying hens.
3.1.1. The main data source of the information
Eggs producers
3.2. Classification system
No classification used (data on egg production and the number of laying hens are not broken down)
3.3. Coverage - sector
The agricultural sector covers activities defined by NACE Rev. 2 as follows:
01.1Â Growing of non-perennial crops
01.2Â Growing of perennial crops
01.3Â Plant propagation
01.4Â Animal production (excluding 01.49 except raising ostriches, rabbits, bee-keeping and production of honey and beeswax)
01.5Â Mixed farming
01.6Â Support activities to agriculture and post-harvest crop activities
and statistical units having at least one of the criteria as follows:
1 ha of utilized agricultural area
1,500 m2 of grown intensive crops (orchards, vegetables, flowers)
1,000 m2 of vineyards
300 m2 of greenhouses
1 cattle
2 pigs
4 sheep and goats
50 poultry
100 rabbits
100 fur animals
The economic activity of holdings keeping laying hens and producing eggs for consumption is classified by NACE code 01.47.
3.4. Statistical concepts and definitions
Eggs for consumption are fresh eggs of fowls of the species Gallus Gallus intended for human consumption (i.e. not intended for incubation), in shell. They are fit for direct human consumption or for preparation of egg products.
Laying hens are fowls of domestic species Gallus gallus having reached laying maturity and kept for production of eggs for consumption. Pullets as well as fowls producing eggs intended for incubation are not considered here as laying hens.
Eggs producer is an agricultural holding with laying hens producing eggs for consumption during the reference period for economic purpose.
