The income that non-salaried farmers draw from their activity varies greatly.
There are differences in revenue according to the specialisation ; differences are even more noticeable between farms with a same specialisation. The highest incomes are in appellation wines and the lowest among sheep and goat breeders. The unexpected events that can affect this sector, like climate conditions or disease, explain the variability of results.
There was a clear narrowing of the dispersion of income in specialisations that are covered by the 1992 and 1999 reforms of the CAP during the 1990s, to stabilise subsequently, mainly in field cropping and to a lesser extent in cattle breeding. By limiting annual variations, direct subsidies that are independent of production provide stability for the lower farm incomes.
