Integrated Household Living Conditions Survey 2005
Enquête Intégrale sur les Conditions de Vie des Ménages 2005
Integrated Survey (non-LSMS) [hh/is]
The Rwanda EICV is a standardized income and expenditure survey with a periodicity of 5 years. The surveys in the series are as follows:
EICV I 2000-2001
EICV II 2005
EICV III 2010-2011
The 2005 Integrated Household Living Conditions Survey, or Enquête Intégrale sur les Conditions de Vie des Ménages (EICV-II) in French, is the second in the series of surveys designed to monitor poverty and living conditions in Rwanda. The objectives of the study are to provide information on poverty and living conditions in Rwanda and to monitor changes over time as part of the ongoing monitoring of the Poverty Reduction Strategy and other Government policies. The results of EICV-II will be compared with the results of EICV-I in 2001 and the content of the questionnaire will be broadly similar to that of the previous survey. In addition the survey will provide data on household income and expenditures which can be used for updating the weights and market basket for the Consumer Price Index (CPI) and components of the national accounts. Survey data on agricultural activities have also proved to be important for national accounts and will complement information provided by future agricultural and rural sector surveys.
The geographic domains of analysis for EICV-II will be Kigali-Ville, other urban and rural strata at the national level, as well as each of the 11 provinces. Given that Rwanda is predominantly rural, the rural stratum of each province will also be a domain of analysis. In order to provide survey results that are comparable to those of EICV-I, the sample design and survey methodology for EICV-I will be consistent with those for the previous survey.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
The scope of the survey includes:
- Household Identification Particulars
- Household Demographic Characteristic/ Household Roster
- Occupation and Employment
- Household Consumption and Expenditure
- Transfers of Revenue, Income, and Miscellaneous Expenses
- Credit, Durable Goods and Savings
- Demographic Information
- Economy, Infrastructure and Environment
- Agricultural Services
- Community Development
The universe for EICV 2005 includes the households and population living in individual households within all urban and rural areas of Rwanda. The population living in institutions and group quarters such as hospitals, military bases and prisons, are excluded from the sampling frame.

Technical and financial support
The sampling frame for the EICV-I was based on the data and cartographic materials from the 1991 Rwanda Census of Population and Housing, while the EICV-II was based on the 2002 Rwanda Census frame. There were significant changes in the areas considered urban between the two censuses, but these geographic changes are taken into account in the comparative analysis between the EICV-II and EICV-II data.
A stratified two-stage sample design was used for both the EICV-I and EICV-II. The primary sampling units (PSUs) were the enumeration areas or zones de dénombrement (ZDs) defined for the census. The sample of ZDs in each stratum was selected with probability proportional to size, where the measure of size was based on the number of households from the census frame. A new listing of households was conducted in each ZD, and a sample of households was selected at the second sampling stage.
Note: Detailed description of sample design is found in the technical document "Rwanda 2005 ECIV-II sampling and weighting".
Deviations from the Sample Design
Household that was not interviewed as per the original listing and selection was replaced with a reserve household. Each EA had 4 households on reserve. A total of 522 households were replaced over the course of the survey. In addition, several EAs were swapped from their scheduled cyclic visit due to seasonal accessability problems.
Out of the 6900 household sample, 92.4% responded. All 7.6% of households that were not interviewed were replaced.
In order for the estimates from each survey to be representative at the national level, it is necessary to apply sampling weights to the survey data. The weights for the sample households were calculated as the inverse of the overall probability of selection, taking into account each sampling stage. Given the nature of the sample design and the new listing of households, the weights vary by sample ZD. An Excel spreadsheet with all the sampling frame information for the sample ZDs was used for calculating the weights, which were then attached to the corresponding records in the survey data files.

Data Collection Methodology in Urban and Rural Areas
The data collection procedures for EICV 2005 will be similar to those for the previous survey, described in Dr. Scott’s report. This methodology was effective for EICV 2000-2001 and will improve the comparability between the results of the two surveys.
Each sample urban ZD will be enumerated by one enumerator during a cycle of 33 days. The sample urban ZDs will be divided into 10 cycles throughout the year. The 9 sample households in each ZD will be divided into 3 groups of 3 households each. The enumerator will visit one group of 3 sample households each day, the next group of 3 households will be visited the following day, etc. This sequence will be repeated so that each household is interviewed every third day. This 33-day cycle in the urban ZDs will ensure that the payday is covered for salaried employees.
In the case of the rural stratum, a team of four enumerators and supervisors will be assigned to each province. The year will be divided into 10 data collection cycles of 32 days each, and 4 sample rural ZDs will be enumerated within each province during one cycle . The cycles will be further subdivided into two periods of 16 days each for the data collection in each sample rural ZD. The sample rural ZDs will be paired each cycle so that a group of two enumerators can be assigned to each sample ZD. The 12 sample households in each rural ZD will be divided into two groups of 6 households each, corresponding to the workload of one rural enumerator during the 16 day period. Each enumerator will visit a group of 3 sample households every other day.
Distribution of Sample ZDs by Data Collection Cycle within the Year
In order for the EICV 2005 to represent seasonality in the household income and expenditure data, it is important to have a sample that is representative across space and time throughout the 12-month data collection period. Ideally, a nationally-representative sample of ZDs should be enumerated each cycle. Sometimes it may be necessary to adjust the set of sample ZDs to be enumerated each cycle to take into account logistical considerations, weather conditions, etc. In the case of EICV 2000-2001, the distribution of the sample segments over time appears to have been mostly determined by operational considerations, which affected the geographic representativeness of the sample each cycle. This can result in a potential bias when there are geographic differences in seasonality.
For EICV 2005 it is recommended to select a representative subsample of ZDs to be assigned to each cycle for data collection. Therefore the 620 sample ZDs can assigned cycle codes from 1 to 10 systematically. In this way a nationally-representative sample of 62 sample ZDs (10 in Kigali-Ville, 8 other urban and 44 rural) can be assigned to each cycle. Then adjustments can be made to these cycle assignments based on logistical considerations, weather conditions, etc. Given the greater dispersion of a nationally-representative subsample of ZDs each cycle, this may increase the cost of the field operations slightly, but this investment will improve the seasonal representativeness of the EICV 2005 sample. In the case of the other urban stratum, the sample ZDs in each town should be spread evenly across the four quarters of the survey year as much as possible.
