Income and consumption expenditure calculated per consumption unit can be used to compare households of different sizes and structures with each other. There are several different ways of calculating consumption units. From 2002, the income distribution statistics and the Household Budget Survey have used the OECD's adjusted consumption unit scale recommended by Eurostat, the Statistical Office of the European Communities, where
- the first adult of the household receives the weight 1
- other over 13-year-olds receive the weight 0.5
- children receive the weight 0.3 (0 to 13-year-olds).
The selected consumption unit scale has a significant effect on income levels and on placement of different population groups in the income distribution.
