Sampling
Sampling Procedure
The EICV3 sampled a total of 14,310 households in 1,230 sample villages.The sample selection methodology for EICV3 was based on a stratified two-stage sample design.
At the first sampling stage the sample villages for EICV3 were selected within each stratum (district) systematically with PPS from the ordered list of villages in the sampling frame. The measure of size for each village was based on the total number of households identified in the sampling frame of villages. The villages within each district were ordered first by urban, mixed and rural areas, and then geographically by secteur, cellule and village codes. This provided implicit geographic stratification of the sampling frame for each district, and ensured a proportional allocation of the sample to the urban and rural areas of each district.
A listing of households was conducted in each sample village prior to the EICV3 enumeration in order to select the sample households. A systematic sample of 9 households was selected from the listing for each sample village in Kigali Province and 12 households for each sample rural village in the remaining provinces. A reserve sample of 3 replacement households was selected for each sample village in Kigali Province and 4 replacement households for each sample village in the remaining provinces.
Deviations from Sample Design
Two households were dropped due to incomplete data. These were in the urban zone (Kigali). These include Nyraungenge and Kikukiro. These have been adjusted in the weights.
Response Rate
Traditionally response rates are high in Rwanda so it is not surprising to have response rates greater than 95%. For computing the response rates, the DHS definition is used:
1. The numerator are the number of households with a completed household interview.
2. The denominator: is the sum of number of households with a completed household interview, households that live in the dwelling but no competent respondent was at home, households with permanently postponed or refused interviews, and households for which the dwelling was not found.
3. Unoccupied or abandoned dwelling are excluded (no household lives in the dwelling, address is not a dwelling, or the dwelling is destroyed)
The numerator is: 14,308
To compute the denominator the following are considered:
Completed 14,308
HH not found 132
Sick or died 59
Refused 48
Other 63*
Dropped 2
Total: 14,612
The response rate is computed at 98%
*Other is included in the denominator despite the uncertainty of the reason.
**Excluded from the denominator are 368 homes that were reported abandoned or changed.
Dwelling changed (Nyakatasi) 115
Dwelling changed other reason 253
Weighting
In order for the sample estimates from the EICV3 to be representative of the population, it is necessary to multiply the data by a sampling weight, or expansion factor. The basic weight for each sample household is equal to the inverse of its probability of selection (calculated by multiplying the probabilities at each sampling stage).
The basic weights were also adjusted to take into account the non-interviews as well as the replacement households in each sample village.
