Abstract
The Directorate of Analysis, Forecasting and Statistics (DAPS) is responsible, among other functions, for collecting, centralizing, processing and disseminating information on agricultural statistics. These responsibilities are ensured in conjuction with other directorates, services and parastatals of the ministry.
In this context, an Annual Agricultural Survey (AAS) is organized in all regions of the country, to obtain structural and economic data. The survey, implemented by the Statistics, Documentation and Agricultural Information Division, consists of measuring the crop plots for a given crop year. The measuring instruments are compass, milestones, metric tape, programmable calculator and GPS. The plot area is expressed in hectares. Other information on sowing dates, types of distribution, types of crops, inputs used are also collected.
The agricultural survey is an annual statistical operation whose general objective is to estimate the level of the main agricultural productions. It concerns crops grown on family-type farms. The objective of the agricultural survey, for each district, includes:
Every year:
- mid-season crop forecasts, particularly for cereals
- an estimate of the area, yield and production of the main crops at the end of the season
- an assessment of the quantities of inputs held and/or used by the producers
- an assessment of cereal stocks held by producers
Every 5 years:
- the structure and characteristics of the population of agricultural holdings;
- an assessment of the numbers of livestock and farm equipment.

Sampling
Sampling Procedure
The annual agricultural survey is based on a sample of 6300 agricultural households drawn from the frame of the 2002 General Census of Population and Housing. The methodology applied to the agricultural survey is based on a survey two-stage probabilistic with Census Districts (CDs) as primary units, and farms or agricultural households as secondary units.
The statistical universe is made up of the department at the level of which the survey units (farms) are drawn up and the extrapolation calculations of the data collected.

Response Rate
Response rate is 94% at the census district level and 91% at the household level.
Weighting
In each region, the total estimate is obtained thus:
Total area = (M/n) * y
Where;
M is the total number of agricultural households
n is the sample of the households
y is the total area of the sampled households per crop
Total area = (M/n) * y
Where;
M is the total number of agricultural households
n is the sample of the households
y is the total area of the sampled households per crop
