How are the children in the child loop selected?
Questions CH009 to CH020 in module CH about children are only asked for at most four children. When there are more than four children, the CAPI program selects the four children as follows: 1. Sort children in ascending order by • minor (defined as 0 for all children aged 18 and over and 1 for all others), • geographical proximity (CH007) and • birth year. 2. Pick the first four children. When all sorting variables are equal, the CAPI program chooses a child randomly. The variables “chselch1” up to “chselch4” contain the numbers of the children who were selected by the program.
