Besides, according to this approach the weights will represent a subjective perspective to poverty, deprivation and well-being. However, as mentioned before on the discussion of the concepts of (child) well-being, this method is not used often, since it is not possible and/or suitable to attach a price to many of the aspects of well-being. Alkire and Santos (2010) assign an equal weight to each dimension (33.3% for each of the three dimensions) since, according to the authors, there are no compelling reasons to consider one dimension to be more important than another. The authors, however, use a different number of indicators in each dimension, which results in having different weights for the indicators, varying from 5.6% for indicators in the 'living standards' dimension to 16.7% for the health and education indicators. In the aforementioned analysis of four European countries by Roelen and Notten (2011) the authors use equal indicator weights.
