Note 1: Agricultural Output, Input and Income

In 2000, the CSO revised its methodology for calculating and presenting data relating to output, input and income in agriculture. The new system for presenting the Economic Accounts for Agriculture is the EAA97 basis which differs in a number of ways from the earlier system. The new methodology introduced a number of important changes including an updating of the base year from 1990 to 1995 for the calculation of volume changes. The main difference is a move away from the 'national farm' concept. (This meant that the whole agriculture of a country was regarded as one big farm.) With the new methodology the concept of the "national farm" has been replaced by the use of the individual farm as a unit. With this change certain transactions between farms and between different enterprises within the same farm are now valued as both output and intermediate consumption (inputs).

Valuation of Agricultural Output

Under the new methodology output is valued at the basic price. The basic price corresponds to the producer price plus any subsidies directly linked to a product less any taxes on products. Under the old methodology output was valued at producer prices. The producer price is the price received by the farmer, and is sometimes referred to as the farm-gate or ex-farm price (excluding VAT).

In June 2004 the CSO published further revised figures for the period 1990-2003 using the new methodology. Figures using the old methodology were not revised and are available up to 1998. The new and old methodology tables are broken down in the Compendium under the following headings:

G- Output, Input and Income in Agriculture (new methodology)
Ga- Output, Input and Income in Agriculture (old methodology)

H- Commodities (new methodology)
Ha- Commodities (old methodology)

Any queries relating to the new methodology tables prior to 1990 should be directed to the Agricultural Section, CSO.

Note 2: Employment

PES:The PES (Principal Economic Status) classification is based on a single question in which respondents are asked for their own assessment of their principal economic status.

ILO:The ILO (International Labour Office) is the standard international classification, which classifies respondents as economically active, in employment or unemployed, or economically inactive (not in the labour force) on the basis of their experience in the week before the survey.

See tables A2, C1, F1, F2, F4 and F5.

Note 3: Farm Numbers

Until the 1991 Census, the CSO recorded all farms over 1 acre. From 1991 onwards, only farms over 1 hectare (2.471 acres) are recorded.

See tables L1, L2, L4 and L5.

Note 4: National Farm Survey

Demographically Viable:

Percentage of farm households which have at least one member below 45 years of age.

Gross Output:

Gross output for the farm is defined as total sales less purchases of livestock, plus value of farm produce used in the house, plus receipts for hire work, service, fees etc. It also includes net change in inventory, which in the case of cows, cattle and sheep is calculated as the change in numbers valued at closing inventory prices.

Gross Margin:

Gross output minus direct costs

Family Farm Income:

Gross output less total net expenses. It represents the total return to the family labour, management and capital investment in the farm business.

Labour Unit:

One labour unit is defines as at least 1800 hours worked on the farm by a person over 18 years of age. Persons under 18 years of age are given the following labour unit equivalents. 16-18 years: 0.75; 14-16 years: 0.50. [An individual cannot exceed one labour unit even if he/she works more than 1800 hours on the farm.]

Utilisable Agricultural Area (UAA):

Area under crops and pasture plus the area (unadjusted) of rough grazing. It is the total area owned, plus area rented, minus area let, minus area under remainder of farm.

See tables M1, M2, M3, M4, M5 and M6
