The indicators for the type of water supply, the fuel used for cooking and the material used to build house walls are exceptions in that the most common profiles for these indicators are two-dimensional profiles that are combined with the “sewerage system” indicator. The results that do not display a level of frequency in absolute terms (i.e., indicators that are more likely to appear in combination with others than alone) are shown in table 6. For example, although the number of households that lack running water is not numerically significant, the two-dimensional “sewerage system-running water” indicator is significant.
