EnglishThe literature offers two main ways of decomposing the Gini index: decomposition by population subgroup and by income source. This paper proposes merging the two decomposition dimensions by suggesting a matrix formula for the Gini index which permits the simultaneous decomposition by subgroup and by income source. Using this multi-decomposition, one can investigate the role of the interaction between the subgroup and the source components in determining the overall inequality.
