Consumption unit (OECD)

The size of the consumption unit represented by the household-dwelling unit is indicated as the sum of the weights of its members. In accordance with international recommendations the value of each member of a household-dwelling unit is determined as follows:
- first adult aged 18 and over = 1.0
- subsequent adults aged 18 and over = 0.7
- each person aged under 18 = 0.5.

If all persons in the household-dwelling unit are aged under 18, the weight of the first member is 1.0 and that of subsequent members 0.5.
