This also points to the fact that constructing a deprivation indicator explicitly means reducing the underlying dimensions to one single dimension; items that do not scale on this, are then left out of the analysis (see de Neubourg and Plavgo, 2012 for more detail). In order not to lose the information revealed by these indicators we will take them again into consideration when discussing the overlap between the domains in section 4 of this paper. One item (holidays) was excluded because the data were lacking for 9 countries; an attempt to make a holiday composite by using the adult holiday question failed because we found that this was not a reliable proxy4 for children’s holidays.
