The Common Agricultural Policy reform of 2003 establishing the decoupling of agricultural aid connected to the production led to create the concept of Standard gross production (SGP) which succeeds to the ancient concept of Standard gross margin (SGM) henceforth obsolete. It ensues a new European typology of farms.
This new classification of the farms according to their main production (type of farming, TF) and according to their size (economic farm size) applies for the first time for the results of the agricultural census of 2010 (then to surveys "structure") as well as in the farm accountancy data network
A farm is specialized in a type of farming (TF) if the SGP (standard gross production) of one or several concerned productions exceeds two thirds of the total
The Type of Farming is a European classification.
