The present study seeks to implement robustness tests focused on traditional child poverty measurements by incomes and multidimensional child poverty, when changes are applied in the size and composition of the households (equivalence scales), scale economies within the households, poverty lines for each indicator (including monetary variables), ponderations, dimensions and multidimensional thresholds (k). This analysis is crucial when the effect of child-poverty-eradication policies is discussed, mainly considering the goals and targets established by the SDGs.
