In the frame of the Farm Structure Survey, data are collected on the structure of the agricultural and forestry holdings, including data on holdings, which apply organic farming production methods; either already certified or to be certified according to national or EU rules: specifically their number, structure, area and livestock.
According to EU-legislation, a census is conducted every ten years, with sample surveys in three-year or four-year intervals in between. All agricultural and forestry holdings which meet the minimum requirements set out in the legislation are required to take part. Relevant available administrative data sources are used, and complemented with questionnaires.
For the census, regional data are available – partially at the municipality level. In survey years, the smallest geographical unit available is that of the federal province.
