Pigs, sheep and goats: Under the title "General livestock survey", around 7 000 farms are directly surveyed using a stratified random sample every year for the reference date 1 December. These livestock reports of pigs, sheep and goats are extrapolated to federal province and national results. The annual calculation of the pig population for the reference date 1 June has been carried out using a regression model based on data from the consumer health information system (VIS).
Bovines: The separate determination of the bovine population is carried out for both reference dates by evaluating the central cattle database of Agrarmarkt Austria (AMA). The results are derived from an intersection of AMA and Rinderzucht Austria data, with the detailed processing of the results carried out by Statistics Austria since June 2022.
Chickens: From 2025 onwards the annual chicken population is determined using data from the Quality Poultry Association (QGV), AMA and VIS. It is reported as the daily average number of chickens kept on agricultural holdings.
Organic: Due to the Commission Implementing Regulation (EU) 2023/2745, from 2025 onwards the organic livestock population will also be determined.
