1. Introduction
Ethiopia is a country with agrarian economy, where Agriculture is the dominant sector of the country’s Economy, as a matter of this fact, The sector contributes (Nearly 45%) to the country’s GDP It employs 82% of the country’s total population, who solely depends on agriculture for their livelihood It is the main source Of the domestic food supply and Raw materials for domestic Agro-Industries
S
C A Why do we need continues, comprehensive, reliable and timely supply of quantitative information? Because statistical information with regard to agriculture are indispensable input To evaluate and monitor the performance of the sector itself To formulate promotional agricultural policy and programs To design, plan and execute developmental agricultural projects,
To monitor and evaluate the ongoing agricultural projects and programs and …etc

2. Initiation of Annual Agricultural Sample Surveys (AGSS)
Three decades earlier, statistical information regarding the agricultural sector were rarely available in Ethiopia, Due to limitation of both coverage and methodology used the information generated during those days were inadequate and unreliable.
In addressing the problems mentioned, in 1980 “Integrated System of Food and Agricultural Statistics (ISFAS)’’ the UNDP/FAO project, was initiated in Ethiopia.
S
C A Thus, from 1980 on wards Ethiopia/CSA has been conducting the agricultural sample survey on annual bases.
Here it should be noted that in addition to conducting the annual agricultural sample surveys, the country had performed the first ever agricultural sample enumeration in 2001/02 Since then every three and/or four years the CSA used to improve the content, coverage and methodologies of the annual agricultural sample surveys.

Survey
The range of data items includes
Area and production of and permanent crops,
both temporary
Land use i.e. total cropland area, fallow land, grazing land, forest land and …etc,. Agricultural practices, various inputs
such
as
use
Number of livestock and poultry by type, purpose, age and sex
It should be noted that all the above mentioned data items are first identified in consultation with all data users and concerned stakeholders

5. Area and Sector Coverage
C A
The Annual Agricultural Sample Survey covered
The entire rural parts of the country except the
non-sedentary
population
of
Pastoral
areas
Both private peasant and large and medium scale commercial farms agricultural holdings including Co-operatives’

6. Sample Design and Sample Size A
stratified
two-stage
cluster sample design was
implemented, where, Enumeration areas (EAs) were taken to be the primary sampling units (PSUs) and the secondary sampling units (SSUs) were agricultural households. The sample size is determined by taking into account of both the required level of precision for the most important
estimates
within
each
domain
and
the
amount of resources allocated to the survey. All the regions of the country which are eleven in number were taken to be the domain of estimation for which major findings of the survey are reported.

6.1 Sample Selection
First Stage sample selection of EAs was done by probability proportional to size (PPS). Size is the total number of households compiled from the 2007 (1999 E.C.) population and housing census. Second Stage sample (household) selection was done by systematic random sampling. Currently 30 agricultural Households were sampled from each EA selected to be covered by the survey

7. Field Organization
Through its 25 Branch offices the CSA has put in place a comprehensive field organization to follow up and monitor the survey field work.
Currently, one supervisor is assigned to closely supervise and follow up the work of 3 - 4 enumerators Annually,
field
enumerators,
are
recruited,
trained
and
assigned in the sampled EAs by each of the respective Branch Offices. All the technical personnel, heads of the 25 Branch Offices as well as field supervisors and enumerators were fully involved.

8. Training Of Field Staff

The quality of data acquired from the survey highly
depend on the type of training given, The CSA provides theoretical and practical training at
various stages to its field staff The

9. Method Of Data Collection The
CSA
adopted
both
subjective
and
objective method of data collection in its annual agricultural sample surveys. a) Agricultural data collected using objective method are:−
Land area under Crop,
−
Crop Yield through conducting Crop cutting experiment from 2 mts x 2 mts plot of land,
−
Land Utilization (Area under different land use).
S
C A
b) Data collected through interview method are:Demographic
characterstics
of
the
sampled agricultural households
Data on agricultural inputs such as use fertilizers, local and improved seeds, use of pesticides, herbicides, and use of irrigation,
Quantity and Cost of agricultural inputs
Livestock,
poultry
and
beehives
enumeration and their products by type.

10. Dissemination of the Survey Results
The results of the Annual Agricultural Sample Survey are disseminated to ultimate users’ through 1.
Hard copy:- The CSA distribute the Hard copies to the concerned stakeholders, made few copies available at the library for free use and put enough copies at CSA store for sale.
2.
CD:-Softcopy of the survey results are also made available on CDs to ultimate users
3.
Web Site:- Softcopy of the survey results are also released for free use through the CSA web site.
