Household expenditure consists of the entire flow of money that household economies devote to the acquisition of consumer items, plus supplies, self-consumption goods, or any salary in kind, despite these last items not implying any monetary flow.
The expenditure can be calculated per person in the household and unit of consumption in the household. In order to obtain the units of consumption we use the so-called equivalence scales, which turn household members into units of consumption. These equivalence scales are applied because economies of scale are generated when a household shares certain goods and services, which means that the needs of a household with n persons are sometimes lower than the needs of a household with just one person.
In this case we use the modified OECD scale, which gives the following values to each member of the household:
- Main provider: 1
- Adult other than 13: 0,5
- Child 13 and under: 0,3
The total expenditure of a household is divided by the number of units of consumption in the household and we thus obtain the equivalent expenditure per unit of consumption. Each member of a household is assigned the equivalent expenditure of his or her household.
Expenditure is presented classified according to the Classification of the Functions of Individual Consumption (COICOP/HBS) until 2015. From 2016 onwards, the European Classification of the Functions of Individual Consumption (ECOICOP) is used. These two classifications are not entirely comparable.
These statistics are conducted upon the basis of the Family Budget Survey carried out each year by the INE. Idescat processes this data in detail on a yearly basis, expanding the results for Catalonia.
