This paper shows that there is no need for a selection of a single inequality indicator. A whole set of inequality indicators are considered and calculated for the European Countries, using income data from European Community Household Panel (ECHP). The information they provide is then collapsed into a composite inequality indicator, through an adaptation of Principal Component Analysis (PCA). We analyze the conditions needed to make longitudinal comparisons possible. Results obtained with this composite indicator are used to compare and analyze the trends in economic inequality in the EU Countries.
