Series Information
The Agricultural Census (AC) 2010 was the first AC conducted in Iceland.
Abstract
In compliance with Regulation (EC) 1166/20081 , Statistics Iceland conducted the Farm Structure Survey (including the Survey on Agricultural Production Methods and Other Gainful Activities), covering all national holdings, in 2010. The action is defined as the beginning of a regular collection of agricultural data with the use of this survey. This action has not been administered previously by the national statistical institute.
A range of administrative data sources was used for the action, however, the situation in Iceland is characterised by some shortcoming in this area. The lack of a business and a farm register, as well as the lack of any other complete data source with an overview of holdings, proved to be a complication. Administrative data sources that were utilized, such as tax registers, have units identified through individual identity numbers. In cases where more than one person from the same holding are registered that holding has multiple entries. Linkages between individuals, to establish complete holdings, had to be made after the data collection of the survey, as a part of a data clean-up phase. Time restrictions and lack of resources made it impossible for this work to be done at an earlier stage.

Sampling
Sampling Procedure
a. Frame
Iceland does not have a farm register, nor any other complete data source with an overview of holdings. The census frame was built using Agricultural Tax Returns, VAT Returns and Annual Livestock Surveillance Reports. The initial census listing consisted of 3 241 individuals, and was later revised to 2 699 holdings.
b. Complete and/or sample enumeration methods
The AC was conducted using complete enumeration

Data Collection Mode
Mail Questionnaire [mail]
Data Collection Notes
Data were collected using a mixed mode strategy (CAWI, mail-out/mail-back, CATI). First, a pre-notification letter was sent to all agricultural holders informing them that an invitation to a web survey would be sent in a few days. In the invitation letter, respondents were provided with a web address for the web questionnaire, as well as a login name and a password. For the units that did not respond through the Internet, a paper questionnaire was sent, along with a prepaid return envelope. This was done approximately two weeks after the original invitation to the web questionnaire. Some holding characteristics were collected directly from the administrative data sources
Questionnaires
Questionnaires
The census questionnaire was available in three formats, for PAPI, CAWI and CATI data collection. Fourteen of the total 16 core items recommended in the WCA 2010 were covered by the census
Data Processing
Data Editing
a. DATA PROCESSING AND ARCHIVING
Three employees of Statistics Iceland entered manually the answers from the paper questionnaires to a database. Finally, for those who answered neither the web questionnaire nor the paper questionnaire, CATI was applied. Blaise survey software was used to create the data files for the data collected through CAWI and CAM R software was used for data handling. Identification numbers, which were present both for holders and legal units, were used to link data from different data sources. Home addresses and land codes were used to link holders, as holdings in Iceland can have multiple holders.
b. CENSUS DATA QUALITY
Completion and correction methods were applied in cases of missing values and implausible values. No follow-up interviews were conducted. Administrative data were used for the missing values, as well as for the validation of the AC results, where the information was available.
