Household Income, Consumption and Expenditure Survey 1999-2000
Income/Expenditure/Household Survey [hh/ies]
The need for comprehensive economic statistics has been recently growing rapidly in most developing countries in view of the use of such statistics in formulating socio-economic development plans in general, and to assess the socio-economic situation at the household level such as the one obained from Household Income, Consumption and Expenditure Survey, on a regular basis are the major sources of these data. The survey provides valuable data, especially for assessment of the impact of policies on the conditions and levels of living of houeholds. It is a well known fact that surveys of Household Income, Consumption and Expenditure usually have the major goal of providing basic data needed for the purpose of designing socio-economic policy as well as other related issues that might arise at the micro level.
The major objectives of the survey are to:
- Provide data on the levels, distribution and pattern of household income, consumption and expenditure that will be used for analysis of changes in the levels of living standards of households over time in various socio-economic groups and geographical areas.
- Obtained information for the formulation of socio-economic plans and policies.
- Furnish bench mark data for assessing the impact of existing or proposed socio-economic programs on household living conditions.
- Provide data for compiling household accounts in the system of national accounts, especially in the estimation of private consumption expenditure.
- Obtain weights and other useful information for the construction of consumer price indices at various levels.

The 1999-2000 Household Income, Consumption, and Expenditure Survey covered both the urban the sedentary rural parts of the country. The survey has not covered six zones in Somalia Region and two zones in Afar Region that are inhabited mainly by nomadic population. For the purpose of the survey, the country was divided into three categories. That is, the rural parts of the country and the urban areas that were divided into two broad categories taking into account sizes of their population.
Rural parts of nine Regional States and two administrative regions were grouped in this category each of which was the survey domains (reporting levels). These regions are Tigray, Afar, Amhara, Oromia, Somalia, Benishangul-Gumuz, SNNPR, Gambela, Harari, Addis Ababa and Dire Dawa.
All regional capitals and five major urban centers of the country were grouped in this category. Each of the urban centers in this category was the survey domain (reporting level) for which separate survey results for major survey characteristics were reported.
Category III: Urban centers in the country other than the urban centers in category II were grouped in this category and formed a single reporting level.
Other than the reporting levels defined in the category II and category III one additional domain, namely total urban (country level) can be constructed by combining the basic domains defined in the two categories. All in all 35 basic rural and urban domains (reporting levels) were defined for the survey. In addition to the above urban and rural domains, survey results are to be reported at regional and country levels by aggregating the survey results for the corresponding urban and rural areas. Definition of the survey domains was based on both technical and resource considerations. More specifically, sample size for the domains were determined to enable provision of major indicators with reasonable precision subject to the resources that were available for the survey.
SELECTION SCHEME AND SAMPLE SIZE IN EACH CATEGORY:
1) Category I:
A stratified two-stage sample design was used to select the sample in which the primary sampling units (PSUs) were EAs. Sample enumeration areas (EAs) from each domain were selected using systematic sampling that is probability proportional to size; size being number of households obtained from the rural parts of the country. Within each sample EA a fresh list of households was prepared at the beginning of the survey's field work and for the administration of the survey questionnaire 12 households per sample EA for rural areas were systematically selected.
2) Category II:
In this category also, a stratified two-stage sample design was used to select the sample. Here a strata constitutes all the "Region State Capitals" and the five "Major Urban Centers" in the country and are grouped as a strata in this category. The primary sampling units (PSUs) are the EA's in the Regional State Capitals and the five major urban centers and excludes the special EAs (non-conventional households). Sample enumeration areas (EAs) from each stratum were selected using systematic sampling probability proportional to size, size being number of houesholds obtained from the 1994 population and housing census. A total of 373 EAs were selected from this domain of study. Within each sample EAs a fresh list of households was prepared at the beginning of the survey's field work and for the administration of the questionnaire 16 houeholds per sample EA were systematically selected.
3) Category III:
Three-stage stratified sample design was adopted to select the sample from domains in category III. The PSUs were other urban centers selected using systematic sampling that is probability proportional to size; size begin number of households obtained from the 1994 population and housing census. The secondary sampling units (SSUs) were EAs which were selected using systematic sampling that is probability proportional to size; size being number of households obtained from the 1994 population and housing census. A total of 169 sample EAs were selected from the sample of other urban centers and was determined by proportional allocation to their size of households from the 1994 census. Ultimately, 16 households within each of the sample EAs were selected systematically from a fresh list of households prepared at the beginning of the survey's fieldwork for the administrator of the survey questionnaire.
With regard to ultimate sampling units, it was planned to covered a total of 17,336 households (8,664 in rural and 8,672 in urban areas) all over the country. The response rate was about 100 percent (99.95 percent or 8,660 households in rural and 100 percent or 8,672 households in urban areas). Only four of the selected rural households in Afar region refused to cooperate in giving responses to the questions asked in the survey.

First round data collection (G.C calender)
Second round data collection (G.C calender)
Data Collection Mode
In surveys of this kind, regular supervision is a compulsory component of the whole data collection process. Thus, the field supervision activity of the 1999-2000 HIES has started right after the first round data collection was lunched. During the survey fieldwork, close and regular supervision was undertaken at various levels. During the training period, the management staff from the head office visited all branch statistical offices and discussed the objectives, importance of the survey, the expected quality of the data and some other related issues with supervisors and enumerators. Immediately after the commencement of fieldwork, close supervision was made by supervisors who made spot-checking, re-interviewing and a thorough scrutiny of filled-in questionnaires to ensure that the data collected activities are took place according to the instructions given in the enumerators' instruction manual and during the training. In addition to this, in the process of data collection operation supervision was made by the trainers from the head quarters (senior professional staff) and the branch statistical office heads.
Data Collection Notes
A pilot study has been conducted in Addis Ababa and in some rural enumeration areas of Oromiya for a period of one month (15 March 1999 - 30 March 1999). A total of seven enumeration areas, ten in Addis Ababa and three in the mentioned rural areas were covered by the pilot study. Some 50 rural and urban households were interviewed in this exercise. In general, this exercise enabled the Authority to make some important improvements to the final survey document and to assess and allocate the necessary technical as well as administrative and logistics support needed for the survey.
Training of field staff:
For this survey the training program for the enumerators, supervisors and other field and office staff was conducted at two stages. The first stage was conducted at the CSA head quarters, in Addis Ababa. The participants were selected from professionals and sub-professionals with long time experiences, branch office heads and their assistants who were to train enumerators and supervisors during the second stage of training conducted at the branch statistical offices.
The training at the head office, which lasted for fifteen days, consisted of theoretical discussions on how to complete the questionnaire as well as practical interview of households and/or household members. The objectives of practical interviewing of households were two fold. Firstly, it enabled to assess how well the theoretical class discussions were understood by all participants so that they could convey the same message to enumerators and supervisors. The second objective was to examine the difficulty which would likely to be encountered during the actual fieldwork.
Thorough discussions in the class room were made after field practice. The discussions were intended to help exchange experiences among participants and pinpoint the areas of the survey questions which need more care and attention. This practical fieldwork was conducted both at the head office and at branch offices in selected areas.
The second stage training was undertaken at the branch statistical offices. The trainers were that professional and sub-professional staffs who was trained at the head office. The second stage training lasted for twenty five days and also consisted of both theoretical class discussions and practical field practice. Furthermore, refreshment training was given for ten days to the enumerators and supervisors before launching the data collection operation in the second round of the survey which was carried out during January - February 2000.
All the 22 branch statistical offices of the CSA participated in the survey undertaking, especially in organizing the second stage training, in deploying the field staff to their respective sites of assignment, and retrieving completed questionnaires form the sample sites and submitting them to the head office for data processing. They were also responsible in administering the financial and logistics aspects of the survey within the areas of their assignment. To accomplish the data collection operation, all enumerators were supplied with the necessary equipment (kichen balance and measuring tape) at the completion of the training.

The Household Income, Consumption and Expenditure Survey questionnaire contains the following forms:
- Form 1: Area Identification and Household Characteristics
- Form 2A: Quantity and value of weekly consumption of food and drinks consumed at home and tobacco/including quantity purchased, own produced, obtained, etc for first and second week.
- Form 2B: Quantity and value of weekly consumption of food and drinks consumed at home and tobacco/including quantity purchased, own produced, obtained, etc for third and fourth week .
- Form 3A: All transaction (income, expenditure and consumption) for the first and second weeks except what is collected in Forms 2A and 2B
- Form 3B: All transaction (income, expenditure and consumption) for the third and fourth weeks except what is collected in Forms 2A and 2B
- Form 4: All transaction (expenditure and consumption) for last 6 months for Household expenditure on some selected item groups
- Form 5: Cash income and receipts received by household and type of tenure. The survey questionnaire is provided as external resource.
Due to complex nature and magnitude of the survey, CSA has given special attention to the data processing activity. Thus, a task force comprising of subject matter specialists and data processing experts was formed to oversee the data processing and analysis activities of the HIES starting from August 1999. After the completion of the first round of the survey data collected operation, the filled-in questionnaires were retrieved from the field, the task force embarked on the first stage of data processing activities, i.e. manual editing, coding and verification. Experienced editors-coders and verifiers have been deployed for this activities. Considering the complication of the data collected in this survey the editing, coding and verification of the questionnaires have taken the most part of the three months after which data entry was started.
For the data entry activity, the Integrated Microcomputer Processing System (IMPS) software was used throughout. To speed up this process, experienced data entry operators were used and the data entry activity was completed in December 1999. The survey data collected during the second round (January 1999 - February 2000) have also passed through all the data processing activities stated above for the first round.
After the data entry of both rounds of the survey has been completed, the next step in the data processing activity was to merge the data from the first and the second rounds of the survey. Unlike the 1995-1996 Household Income, Consumption and Expenditure Survey, which was done with the help of a short term consultancy services provided by Statistics Norway, the merging operation of these surveys was successfully completed in October 2000 by the programmers in the Data Processing Department of the CSA, after which data cleaning, detailed and through consistency checking were done. In fact, the data cleaning and the consistency checking, which were important for the generation of the final tabular reports, were done both manually and by computer.
