Household Income, Consumption and Expenditure Survey 2004-2005
The HICE survey basically reflect the income dimension of poverty while WM survey aims at providing socioeconomic data that reflect the non-income dimension of poverty. The HICE survey provides statistics on income, consumption and expenditure of households and WM survey provides basic indicators on the various socioeconomic areas including health, education, nutrition, access to and utilization and satisfaction of basic facilities/services and related non-income aspects of poverty. The HICE survey has been conducted together with the WM survey every four-five years since 1995/96. The latest of these HICE surveys is for 2004/5 and covered a representative sample of 21,600 households. Previous HICE were similarly representative, covered 11,928 and 17,332 households for 1995/96 and 1999/00, respectively.
Unlike the previous two HICE surveys that had been conducted in 1995/96 and 1999/00, in the 2004/05 HICE survey data on Household Consumption Expenditure and Household Income were collected independently using separate modules. However, this statistical report concentrates only on the household consumption expenditure part.
The core objective of the HICE survey is to provide data that enable to understand the income aspects of poverty and the major objectives are to:
- assess the level, extent and distribution of income dimension of poverty;
- provide data on the levels, distribution and pattern of household expenditure that will be used for analysis of changes in the households' living standard level over time in various socio-economic groups and geographical areas;
- provide basic data that enables to design, monitor and evaluate the impact of socio- economic policies and programs on households/individuals living standard;
- furnish series of data for assessing poverty situations, in general, and food security, in particular;
- provide data for compiling household accounts in the system of national accounts, especially in the estimation of private consumption expenditure; and
- obtain weights and other useful information for the construction of consumer price indices at various levels and geographical areas.

The list of households obtained from the 2001/2 Ethiopian Agricultural Sample Enumeration (EASE) was used as a frame to select EAs from the rural part of the country. On the other hand, the list consisting of households by EA, which was obtained from the 2004 Ethiopian Urban Economic Establishment Census, (EUEEC), was used as a frame in order to select sample enumeration areas for the urban HICE survey. A fresh list of households from each urban and rural EA was prepared at the beginning of the survey period. This list was, thus, used as a frame in order to select households from sample EAs.
For the purpose of the survey the country was divided into three broad categories. That is; rural, major urban center and other urban center gories.
Rural: - This category consists of the rural areas of eight regional states and two administrative councils (Addis Ababa and Dire Dawa) of the country, except Gambella region. Each region was considered to be a domain (Reporting Level) for which major findings of the survey are reported. This category comprises 10 reporting levels. A stratified two-stage cluster sample design was used to select samples in which the primary sampling units (PSUs) were EAs. Twelve households per sample EA were selected as a Second Stage Sampling Unit (SSU) to which the survey questionnaire were administered.
Category II:- Major urban centers:- In this category all regional capitals (except Gambella region) and four additional urban centers having higher population sizes as compared to other urban centers were included. Each urban center in this category was considered as a reporting level. However, each sub-city of Addis Ababa was considered to be a domain (reporting levels). Since there is a high variation in the standards of living of the residents of these urban centers (that may have a significant impact on the final results of the survey), each urban center was further stratified into the following three sub-strata.
Sub-stratum 1:- Households having a relatively high standards of living
Sub-stratum 2:- Households having a relatively medium standards of living and
Sub-stratum 3:- Households having a relatively low standards of living.
The category has a total of 14 reporting levels. A stratified two-stage cluster sample design was also adopted in this instance. The primary sampling units were EAs of each urban center. Allocation of sample EAs of a reporting level among the above mentioned strata were accomplished in proportion to the number of EAs each stratum consists of. Sixteen households from each sample EA were finally selected as a Secondary Sampling Unit (SSU).
Category III: - Other urban centers: - Urban centers in the country other than those under category II were grouped into this category. Excluding Gambella region a domain of “other urban centers” is formed for each region. Consequently, 7 reporting levels were formed in this category. Harari, Addis Ababa and Dire Dawa do not have urban centers other than that grouped in category II. Hence, no domain was formed for these regions under this category.
Unlike the above two categories a stratified three-stage cluster sample design was adopted to select samples from this category. The primary sampling units were urban centers and the second stage sampling units were EAs. Sixteen households from each EA were lastly selected at the third stage and the survey questionnaires administered for all of them.
Sample Size and Selection Scheme
Category I: - Totally 797 EAs and 9,564 households were selected from this category. Sample EAs of each reporting level were selected using Probability Proportional to Size (PPS) with systematic sampling technique; size being number of households obtained from the 2001/2 Ethiopian Agricultural Sample Enumeration. From the fresh list of households prepared at the beginning of the survey 12 households per EA were systematically selected and surveyed.
Category II: - In this category 485 EAs and 7,760 households were selected. Sample EAs from each reporting level in this category were also selected using probability proportional to size with systematic sampling method; size being number of households obtained from the 2004 EUEEC. From the fresh list of households prepared at the beginning of the survey 16 households per EA were systematically selected and covered by the survey.
Category III:-127 urban centers, 275 EAs and 4,400 households were selected in this category. Urban centers from each domain and EAs from each urban center were selected using probability proportional to size with systematic sampling method; size being number of households obtained from the 2004 EUEEC. From the listing of each EA 16 households were systematically selected and the survey was carried out on the 16 ultimately selected households.
Including region rural, region urban and country domains, totally 61 reporting levels (including the 10 sub-cities of Addis Ababa) were formed. For the overall distribution of planned and covered EAs and households see Annex I of the 2004-2005 Household Income, Consumption and Expenditure Survey (HICE).
In the rural part of the country it was planned to cover 797 enumeration areas (EAs) and 9,564 households. However, due to various reasons 3 EAs and 64 households were not covered by the survey. The overall response rate is 99.62 percent for EAs and 99.3 percent for households. For urban areas 760 EAs and 12,160 households were planned to be covered ultimately, 100 percent of EAs and 99.50 percent of households were successfully covered by the survey.

Mode of data collection
In survey of this type, regular and intensive supervision is necessary and crucial component of the whole data collection process. A regular supervision, which is also compulsory activity in the CSA surveys, has been undertaken at various levels to ensure the quality of the data. The permanent field supervisors were assigned to take care of the day-to-day supervision activities. Branch Statistical Office heads and statisticians were also involved in the regular supervision operation. Moreover, most of the professionals and sub professionals from the head office that were engaged in the training of the field staff were also deployed in the actual field supervision. A team comprised the top management has also visited the fieldwork of the survey.
Type of Research Instrument
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.

Data Editing, Coding and Capturing:
The first step of data processing activities was the training of 40 data editors/ coders and 20 supervisors by subject matter department staff members for the first round survey data. The data capturing (data entry) operation was carriedout using about 60 computers and as many data encoders. Similarly, the data processing activities of the second round survey were undertaken by about 60 editors/coders and 25 verifiers for about 85 days. Data entry operation took about 60 days using 125 computers and as many data encoders.
Data validation and cleaning activity was carried out by subject matter specialists and data processing programmers. The data cleaning and validity checking activities were carried out at commodity, and visit levels and has been done systematically. For this purpose various type of edit specification documents were prepared by subject matter specialists and used for the data cleaning purpose.
The data cleaning and validation activities have passed through various steps, such as:
- Estimation of missing observations (either value or quantity) using the available results of the price survey that was collected at the time of the survey from a near- by market places;
- Validity and consistency of quantity and value of consumption items were checked at a visit level based on internal 1and/or external 2 price data;
- Estimation (conversion) of consumption of own production using the observed quantities and the external price survey data;
- Comparison of the household expenditure were made on durable goods that were collected at different reference periods (3 and 6 months) in order to decide whether to utilized the 3 or 6 month's data for the analysis, and similar validation techniques have been carried out.
After completing the data cleaning and validation activities two sets of six month's estimates were separately created prior to merging the two rounds data sets. Due to the nature of the survey, the validity checking and data cleaning activity has taken a long period of time.
The data processing activities were undertaken at the head office. These activities included manual editing, coding, verification, and data capturing (data entry) in its first stage. Consistency checking, and data validation activities has been carried out in the second stage, while estimation with proper sampling weights and tabulation activities were carried out in the final stage of the data processing by concerned professionals
