Definition of concepts

Woody crops
Composed of plants whose above ground part is of woody consistency. These occupy the land for long periods of time and do not need to be replanted after each harvest. Excludes areas of forest and their plantations.
Farm
Technical-economic unit from which agricultural products are obtained under the responsibility of one titular agent. Characterised by the use of a single set of means of production (labour, machinery, etc.). Includes exclusively forestry operations and prohibited hunting zones. Depending on the surface area, these can be with land or without land.
Gross margin (GM)
Difference between the monetary value of total gross agricultural production and the value of certain costs that are directly inherent to this production. For each operation, the gross margin of a certain activity is calculated by multiplying its physical dimension, in hectares or head of livestock, depending on each case, by the corresponding coefficient. The sum of the gross margins of all operations provides the total gross margin (TGM) of the same. The financial dimension of an agricultural operation is determined by its total gross margin (TGM) expressed in EU measurement units that are called European size units (ESU). An operation has a financial dimension of one ESU if its TGM is 1,200 euros.
Technical-economic orientation (TEO)
The aim is to group agricultural operations into different and relatively homogenous types, based on the relative proportion of TGM provided by each crop and species of livestock. This typology was created as a tool for statistical analysis to respond to the needs of agricultural policy and enables analysis of the situation of operations on the basis of economic criteria. It creates the possibility of comparing the situation of operations in different areas of the typology, between states and regions of the European Union (EU) and different periods of time, and also study of the relation between the economic dimension of operations and the physical and labour dimensions.

Methodological aspects

Agricultural statistics are generated within the framework of the EU programme on surveys on farm structure conducted by all EU members in order have up-to-date, comparable information on the member states, with the purpose of being used a basic tool for designing the Common Agricultural Policy. This programme establishes that an Agricultural Census shall be performed every ten years and sample-based surveys in the intervening years. For the cycle that starts with the Agricultural census 2009, two triennial surveys are established.

In these censuses, which are exhaustive, all the existing farms are researched, which from 2009, must comply with certain minimum criteria, while in the Surveys on Farm Structure the population studied complies with some less broad minimum criteria and the data is selected by sampling.

The introduction of these methodological changes with respect to previous editions means that the data is not directly comparable.

What is more, the census questionnaire also includes an additional sheet through which information of interest to the Catalan agricultural sector can be gathered.

Between 1989 and 2007, these statistical operations were conducted by Idescat with the support of the Department of Agriculture, Livestock, Fishing, Food and the Environment.

In 2009, the INE became the responsible body for the Agricultural census for Spain as a whole and in Catalonia it works in collaboration with Idescat and the Department of Agriculture, Livestock, Fishing, Food and the Environment, in accordance with the corresponding collaboration agreements.

The Survey on Farm Structure shows the biennial data series for intercensal periods up to 2007. The series will be triennial from 2013 onwards. From 2013 onwards, the thematic sections will include a section on Rural Development and another on Standard Production, which substitutes the processing of economic data on operations which was based on the gross margin until 2007.

Furthermore, in conjunction with DARP, Idescat has generated a variety of informative documents setting out the main results of the Agricultural Census and the Survey on Farm Structure, prior to 2009. The document devoted to the Agricultural Census contains a compilation of the main variables and compares them with the corresponding previous censuses, pointing out and commenting on the basic factors in their evolution in the intervening period.

The documents devoted to Survey on Farm Structure provide data on the main variables in this survey and compare them with the universe of reference of the corresponding Agricultural Census.
