Agricultural Survey [ag/oth]
Ethiopia's economy is predominantly agrarian and the majority of the population in the country is engaged in agriculture. In this respect, the collection of reliable, comprehensive and timely statistical information on agriculture is very essential. The information is expected to be used for the formulation of agricultural policy. The Central Statistical Authority (CSA) has been conducting Agricultural Sample Surveys on annual basis since 1980-1981 (1973 E.C.) to produce some of the statistical data that can be used in planning and policy making activities. The survey was interrupted in 1992-1993 (1985 E.C.) and 1993-1994 (1986 E.C.) because during these two years the CSA was fully engaged in undertaking the preparatory activities for the 1994 Population and Housing Census. However, after, undertaking the 1994 Population and Housing Census, the annual agricultural survey was resumed in 1994-1995 (1987 E.C.), and also conducted for the year 1995-1996 (1988 E.C.).
The general objective of the Agricultural Sample Survey was:
- To estimate the total cultivated land; total production and yield of major crops per hectare; cropland uses (temporary and permanent); quantity and cost of agricultural inputs by type; number of livestock and poultry by type , purpose, sex and age; number of beehives and honey production in the private peasant holdings at national and different reporting levels which are regions or group of zones.

Version 1.1: Edited and non anonymized dataset, for internal use only.
Scope
The scope of annual Agricultural Sample Survey includes:
- Area identification and characteristics of agricultural holder's. This included household's geographic locations, holder's age, holder's sex and educational status.
- List of fields and agricultural practices for pure stand and mixed crops.
- List of permanent crops and number of tress.
- Records of quantity of improved seed, fertilizers and information on crop protection.
- Records of results of area measurements.

Sampling
Sample Design:
A two stage stratified sample design was used for the 1995-1996 (1988 E.C) annual Agricultural Sample Survey. In three regions, namely in Amhara, Oromiya and Southern Nationals and Nationalities Peoples' Region, group of contiguous zones were treated as strata/reporting levels of the survey results. In the remaining regions, the reporting levels were the regions themselves. The primary sampling units (PSUs) in all strata were enumeration areas (EAs). Agricultural households were the ultimate sampling units. The survey questionnires were administered to all agricultural holders in the sampled agricultural households. A fixed number of sample EAs was determined for each stratum/reporting level based on precision of estimates, household size of the stratum and cost considerations. The overall sample number of EAs in a stratum was proportionately allocated to zones/special wereds within the stratum to their household size. From within each zones/special weredas sample EAs were selected with probability proportional to size, size being the total number of households of EAs as obtained form the 1994 census map work. From each sample EA, 25 agricultural households were sampled systematically without replacement from a fresh list of agricultural households. All information were collected form these households except for crop cutting exercise, for which data were collected only from the last 15 agricultural households starting from the 11th selected agricultural households. Moreover, holders within these households were enumerated and the required data were collected form these holders.
A total of 620 enumeration areas (1.1% of the total agricultural EAs) were selected to be covered in all regions. Nevertheless, 8 of them were closed due to various reasons and the survey succeeded to cover only 612 enumeration areas (EAs). The response rate of enumeration area was 98.71%.
Survey instrument
The 1995-1996 annual Agricultural Sample Survey used structured questionnaires to collect agricultural information from selected sample households.
List of forms in the questionnaires:
- AgSS Form 88/0: Used to list all households and agricultural holders in the sample enumeration areas.
- AgSS Form 88/1: Used to list sampled households and agricultural holders.
- AgSS Form 88/2: Used to record crop condition.
- AgSS Form 88/3A: Used to list fields and agricultural practices for, pure stand crops and mixed crops; list of permanent crops and number of tress.
- AgSS Form 88/3B: Used to record quantity of improved seed, fertilizers and crop protection chemicals and price.
- AgSS Form 88/4: Used to record results of area measurements.
- AgSS Form 88/5: Used to list fields and selection of fields for crop cutting and details of record of crop cutting.
Note: The questionnaires are presented in the Appendix I of the 1995-1996 Agricultural Sample Survey Volume I report which is provided as external resource.

Field Organization:
CSA branch statistical office heads, field supervisors and enumerators were fully involved in the survey. Hence, 15 statistical branch office heads, about 140 field supervisors, each supervising 5 enumerators in most cases and about 651 enumerators (including reserve enumerators) stationed in each of the selected EAs, experts from head office, other support staffs and about 62 drivers were involved in the operation. For all enumerators the necessary survey equipment, such as compass, protractors, ruler, measuring tapes, balance scales, poles, ropes and sample bags were made available.
Training of Field Staff:
At the outset all relevant materials, like equipment have been procured, questionnaires and instruction manuals were prepared and printed. Then the training program for the field staffs was carried out in two stages. In the first stage, about 90 trainees, i.e. experts form the head office, branch statistical office heads and some of the field supervisors were given training for one week at the head office. Those trained in the first stage conducted similar training for about 140 field supervisors and about 651 enumerators for 10 days in all the 15 branch offices all over the country. During the training, the field staffs were given detailed class room instruction on the objective and uses of the survey, concept and definitions of terms used, method of area measurement, method of crop cutting and interviewing procedures. The training sessions included thorough field practices with regard to data collection.
Method of Data Collection: The survey data were collected on questionnaires both by subjective and objective methods of data collection. Information on agricultural practices (application of fertilizer, pesticide, use of improved seed and irrigation), livestock, poultry and belg season information were collected subjectively by interviewing the holders in the sampled households. For these cases all selected households have been covered. Moreover, the objective measurements were conducted for the selected households from each sampled EA in which all crop areas were physically measured using compasses and measuring tapes.
Data processing
After the completion of the fieldwork the filled-in questionnaires were retrieved from the branch statistical offices for data processing. The first stage of data processing activity was begun by training data editors and coders at the head office by subject matter department professional staffs. About 55 editors-coders and 8 verifiers took part in the manual editing, coding and verification activities, which lasted for about a month. Edited and coded questionnaires then captured into computer using data entry program which was develop by data processing department. The data entry activities took about 15 days using 28 computers and as many data encoders. Computer data cleaning, attaching weighting coefficients to the data and tabulation activities were carried out procedurally by the professional staff from involved departments at the head office. The Integrated Microcomputer Processing System (IMPS) software was used for data entry, consistency checks and tabulation of survey results.
