RWANDA - Rwanda National Child Labour Survey 2008

The sample of the National Child Labour Survey is a stratified two-stage sampling. The primary sampling stage is a cluster which is constituted of one enumeration block (EB) as it was designed in 2002 Rwanda
General Census of Population and Housing.

At first stage, enumeration areas constructed on the basis of the 2002 Rwanda General Census of Population and Housing served as sampling frame for the drawing of lots of a sample of 300 enumeration blocks
or clusters with the distribution of 10 enumeration blocks per District. The drawing of lots has been carried out with a proportional probability to the size of each cluster. The size has been measured on the basis of
the number of households having children aged 5 to 17 years that constitute each enumeration block, according to the 2002 Rwanda General Census of Population and Housing. To pick those households, one has
considered the households which had children under 13 years old in 2002.

For the second stage where the sampling unit was a household, a household list was first updated in each EB selected at primary stage and then a constant number of households have been selected from the
number of households that have children aged from 5 to 17 years, identified during households listing in each EB.


No any deviation from the sapmling design.


The sample of the 2008-RNCLS initially comprised of 5,510 households. Following some non response cases, the number of households which were interviewed was lower than had
been anticipated in the sample. Non-response cases were due to many reasons including the lack of household location, the change of location of a household, the absence of household 13
members for interview, etc. In total 5,085 households were visited and interviewed during the 2008-RNCLS, representing a response rate of 92.3%.


The weighting of the household is given by the inverse of the probability to select such household(probability products obtained at each sampling stage). Given that all the survey data were entered into computer, it was very easy to relate to a household a corresponding weighting.
