iv. Methodology Used in Agricultural Statistics
Sampling Frameworks:
Iran has a list of agricultural holders. An Agricultural Holder is a
layman or legal person who individually or jointly exercises management control over the
agricultural holding. These holders have technical and economic responsibilities for the
holdings as well as direct roles in the profits and losses. According to results of the Agricultural
Census 2003, there were around 4,3 million agricultural holders in the country, which
according to the Population Census 2011, decreased to 3.7 million. The area of total
agricultural land in the country is 17,665,203 hectares.

Generally surveys employ a two-stage cluster sampling design where the sample village is the
primary sampling unit and the sample operators serve as the secondary sampling units. The
population surveyed is divided into sub-divisions. Considering an acceptable 5 percent error,
the number of villages in the sample is then determined. The samples are determined in each
class by using the optimum allocation method. In order to select the sample units during the
second stage, the sample villages are listed using spot checks so that the holder living in the
villages could be identified. At the end, non-resident beneficiaries are also listed. Finally, the
sample holders are chosen systematically.

The conventional method of data collection is still in force, using hardcopy
documents and questionnaires for all surveys. Data entry is conducted centrally at the CICT
headquarters.
