Strictly speaking, weighting is relevant only for the definition of the basket of goods and services used to set the poverty line. The aggregation of the minimum basket of goods is done by accumulating the monetary value of each of the items within the selected basket of goods. The aggregation of a household's resources is done either by accumulating the household members' income from all (or most) sources, or by accumulating the monetary value (price) of each of the items/services bought or consumed by the household.
