3.13 Long term trends - Net Farm Income (NFI)
While FBI is the headline business-level measure of farm income, it is a relatively new measure of income and only allows comparisons over the last six years. Net Farm Income ( NFI) has a much longer time series available for comparing income levels and examining trends. This measure places all farms on a tenanted basis, with imputed rent costs applied to owner occupiers. It is quite a different measure from FBI, estimating the return only to the farmer and spouse for their managerial input to the farm business.
Looking at the general trend over the last 20 years in actual prices, for the average over all farm types, suggests that, while farm incomes are subject to a considerable level of fluctuation, they more than tripled between 1997-98 and 2010-11. Farm incomes were at their lowest between 1997-98 and 2000-01, due to the ban on beef exports following outbreaks of bovine spongiform encephalopathy ( BSE), a strong pound and weak world commodity prices.
