Agricultural Survey [ag/oth]
This is the first agricultural survey carried out in Mexico. In order to carry out the survey, public consultation and pilot tests were carried out in 2011.
The National Institute of Statistics and Geography (INEGI), in order to strengthen the generation of agricultural statistics, carried out the National Agricultural Survey 2012 (ENA 2012), with the primary objective of obtaining economic and development information on activities related to production of the main crops and livestock species in the country.
The products included in the Survey were defined by their high contribution to the National Gross Domestic Product (GDP); for being important for the population, according to the Sustainable Rural Development Law and for being part of the strategic food products according to the Food and Agriculture Organization of the United Nations (FAO).
The information of the ENA 2012, was captured by a mobile electronic device (tablet type), and a pre-designed questionnaire for each selected production unit. During the interview, land registration was carried out using a cartographic module incorporated into the mobile electronic device. In some cases, a printed map and a basic questionnaire was administered.
Information on the main agricultural and livestock products obtained from the ENA is one of the main sources for planning and making policies, by public and private sector institutions linked to the rural environment. Thus, information from the survey can serve as a primary tool for the analysis of the behavior of the agricultural sector in the context of the economy in the country. In general terms, the survey had the following objectives/outputs:
-
Obtain useful information from the structural point of view of 33 agricultural and livestock products of greater interest in the country.
-
Have current data to support producers and productive organizations in the rural sector, which are part of the agricultural production system, sponsored by the ministry of Agriculture (SAGARPA).
-
Obtain indicators in support of decision-making to implement policies that encourage the adoption of new technologies.
-
Generate information that supports the decisions of new forms of market entry.
-
Identify the problems that producers face in their activities.
-
Facilitate the comparison of information with other sources at an international level and between different regions of the country, in addition to allowing linkage to databases of other projects undertaken by INEGI.
-
Formulate specific research projects with agricultural producers.
-
Provide relevant information on the sector that allows the evaluation of the effectiveness of government policies and agricultural development programs in the country, which have an impact on the food security of the population.

Coverage
National Coverage
The universe for ENA 2012 was made up of 97,442 production units from the 3.94 million units captured by the 2007 Agricultural Census. This universe was defined from the 33 products of interest selected for the survey, 29 which are annual and perennial crops and the rest corresponds to livestock species of economic importance for the country. The products include: Corn, Fodder, Sugarcane, Grasses, Wheat, Avocado, Sorghum, Beans, Chili, Alfalfa, Tomato, Potato, Melon and Watermelon, Coffee, Orange, Grape, Banana, Lemon, Mango, Onion, Pumpkin, Green Tomato, Cotton, Apple, Cocoa, Rice, Barley, Soy, Forage Oats, Cattle, Swine, Poultry and Egg.

Sampling
The sample design was probabilistic, so the results obtained from the survey are generalized to the entire target population, where the sampling unit is the production unit. The sampling frame was formed from the final results of the 2007 Agricultural Census, considering the 3,943,935 production units that reported information on any of the 33 products of interest. Thus, in total, the universe for ENA 2012 was made up of 97,442 production units from the 3.94 million units captured by the 2007 Agricultural Census. This universe was defined based on the 33 products of interest selected for the survey, 29 which are annual and perennial crops, with the rest corresponding to livestock species of economic importance for the country. At the national level, the domains of the study are each of the 33 agricultural products selected; while at the federal entity level, the domains are the main products from this 33 selected products.
Stratified sampling method was used in sampling 31 products. However, for poultry and egg products, only large producers were considered in the sample. The selected crops were classified into stratas according to the land area cultivated in hectares (more than 20; 11-20; 6-10; 3-5; 0-2), while livestock products were classified based on stocks. Crops that fall in the first strata (more than 20 hectares), were further classified into 2 sub-stratas (21-50 hectares; more than 50 hectares). These crops include: Corn, Coffee, Rice, Pumpkin, Grasses, Orange, Wheat, Grape, Soy, Avocado, Banana, Forage oats, Beans, Mango.
For each domain of interest, the sample was assigned in each stratum by applying the Neyman Locking method, for area planted in crops and stocks in livestock products, obtaining a formula for estimation that is presented in the reference material in of the survey. Sample selection was performed independently for each domain-stratum, the selection procedure was random without replacement. A production unit could be selected more than once for containing more than one product.
The expansion factors, both at the national level and at the entity level for each domain-stratum, were calculated as the inverse of the selection probability.
Data collection
| Start | End |
|---|---|
| 2012-10-01 | 2012-11-23 |
The reference period for the different agricultural activities covered in the survey are listed below:
a) September 30, 2012 for the inventory of livestock
b) March 1, 2012 - September 28, 2012 for protected area of cultivation and general characteristics of the land.
c) October 1, 2011 - September 30, 2012 (Agricultural year) for the rest of the themes/topics covered in the survey.
Data processing
After the collection of the data on the field, it was transferred to a national database in INEGI headquarters for review and analysis, through various information processing stages, with the aim of guaranteeing quality, congruence and consistency. Processing and treatment of the data consisted of the following stages:
- Verification of the quality of information provided during capture/data collection
- Assigning codes/keys to variables to facilitate interpretation, processing and analysis
- Standardization of units of measurement
- Final data validation using an automatic validation system, pre-designed with over 200 validation criteria
- Group information analysis
- Comparison with internal and external sources
