In this paper we analyse the response of several methods to construct indices for consistent multiple comparison. We consider also the close formal connection between the comparison of preference judgements and the comparison of economic aggregates. To evaluate the various scaling methods, we have used official data furnished by Eurostat, consequently our analysis is based on real-life data and not on simulations as is usually the case in study in this kind. The most important results that we have achieved are the close concordance of the weights obtained with the various methods and the robustness of the evaluations performed.
