Abstract
The National Institute of Statistics and Census (INEC), through the Directorate of Agricultural and Economic Statistics (DEAGA) executed the Annual Agricultural Area and Production Survey (ESPAC), 2008.
This survey was carried out in Ecuador at the national level, in all provinces, except for the Galapagos and unassigned areas such as Las Golondrinas, Manga del Cura and El Piedrero. It covered all properties with total or partial agricultural activity, called Agricultural Production Units (UPAs). These were selected by the area sampling and list sampling, a methodology that is applied in this survey.
The main objective of the survey is to provide information on the agricultural sector, referring to planted, sown, and/or harvested areas, production and sales of permanent/transient crops, animal/livestock breeding, as well as, the employment of labor. This was done in order to have information for formulating crop plans and diversification of agricultural production, formulating price rules and, incentives to improve agricultural production. It was also done to establish a system of equitable distribution of production in the different areas of the country, contribute to the sectoral economic analysis, as well as, the preparation and execution of import and export policies for agricultural products so that the country, through the national government, can promote policies that strengthen the agricultural sector.

Sampling
Sampling Procedure
The Annual Agricultural Area and Production Survey (ESPAC) 2008 uses the multi-frame sampling methodology (MMM), which consists of a combination of Sample Area Frame (MMA) and a Sample List Frame (MML). The sample frames of each of the provinces of the territory used in the III National Agricultural Census of the year 2000 are applied.
The MMA sampling consists of dividing the total area of the country into small areas without omission, called Primary Sampling Units (UPMs). A UPM is an area of 10 km2 on average and is delimited by natural and/ or cultural barrier that is easily identifiable on the ground. For the operation of the survey, these areas were outlined on an aerial photograph and a map. A second division is made as each UPM is divided into a specific number of Sampling Segment (SM). An SM is an extension of land with an area of approximately 2 km2 or 200 hectares, delimited by natural and/ or cultural barriers easily identifiable on the ground. The set of all SMs constitutes the area frame and covers the continental territory excluding the province of Galapagos and the areas not assigned to any province. The SMs are clearly marked and delineated on an aerial photograph and generally contain one or more Agricultural Production Units (UPAs) or one or several non-UPAs.
The MML is a statistical procedure that consists of extracting information from all or a sample of the elements found in the list frame. This list frame is a directory prepared by the National Institute of Statistics and Census (INEC) where the UPAs that meet certain pre-established criteria are recorded. In the MML are the main UPAs, identified by INEC, the Ministry of Agriculture and Livestock (MAG) and the private sector, based on their importance in terms of contribution to the countries agricultural production.
The sample size consists of randomly selecting a subsample of 2,000 SMs from the area frame, and a list of 4,000 UPAs.

Deviations from the Sample Design
There were no deviations from the original sample design. All sampled segments and sampling units were visited.
Response Rate
In the Annual Agricultural Area and Production Survey of the year 2008, the non-response rate, as well as, other rejection indicators go hand in hand with the sample design implemented, so this rate is not unique or general. This is because some SMs are not investigated due to different reasons, such as: rejections, transportation problems, etc.
Weighting
Expansion factor was derived for use in calculating the weights. It is a numerical value that is given from the design of the sample.

Data Processing
Data Editing
In the Annual Agricultural Area and Production Survey 2008, the Expert System is used. This is a computer system that automatically produces coding once the data is entered. This system also allows for individual review and validation, after which the database is generated. Usually, after data collection, the questionnaire is delivered to the digitizer/ operator who enters the information into the computer in the Expert System. Once the information is entered, it is encrypted, validated and verified. This validation process is implemented in the system to check for inconsistencies and errors. In certain cases, the questionnaire is delivered to the field staff so that the information is verified again, and the data is re-entered. After this, a database is created, followed by processing and analysis to generate results to be published.

Confidentiality
Statistical Law:
Art. 21.- The individual data obtained for the purpose of statistics and censuses are of a reserved nature; consequently, no individual information of any kind may be disclosed, nor may they be used for other purposes such as taxation or conscription, judicial investigations and, in general, for any purpose other than the statistically or census itself.
Access conditions
The study can be accessed at https://anda.inec.gob.ec/anda/index.php/catalog/206
The National Institute of Statistics and Censuses (INEC) considers statistical information produced with resources from the national budget as a public good and as such should be widely available to users. INEC will establish the specific criteria and mechanisms for access to user information, clearly identifying the public good criterion of the cost recovery, criteria for the services produced in support of the financing of its activities, for which will be issued the corresponding protocols for access to information.
Lines of Action:
Access to information protocols:
- The information generated with financing of resources of the national budget, in whole or in part; that is processed, reviewed and available/suitable for dissemination (whether through synthesis indicators, tabulated or harmonized primary databases), and anonymized will be freely available.
- The information generated with financing from public, private or international institutions will be freely available, if there are no explicit indications to the contrary.
- The statistical information will be disseminated in a disaggregated way at the thematic and geographical level, using relative and absolute values, including the available historical information.
- The methodologies and complementary information explaining the potentialities and limitations of the data obtained, such as process reports, quality assessments of statistical operations, among others, will be freely available to users.
- Printed publications of rapid diffusion through brochures, posters, leaflets, among others, will be free.
- Access to the consultation of publications in the Library of the institution will be free.
- All statistical services that involve the consumption of man-hours, such as data processing to meet specific requests, preparation of databases tailored to the user, preparation of reports, graphs and analysis, among others, will have a cost proportional to service size.
- All printed publications (books, newsletters, reports) or in electronic media (CD Rom, diskette) containing results of statistical research will have a cost.
- All photocopying or computer printing services will have a cost relative to the size of the service.
- Sample preparation services and cartographic base will also have a cost proportional to the size of the service.
