Croatia should be included between France and Italy in table 1, since it's now a Member State. Louise Corselli-Nordblad 19/11/2013
I like the article. It provides a an interesting facts and reading. I have one general methodological comment on the use of Gini coeficient and the Lorenz curves. My knowledge on the issue is that due to its mathematical constrcution based on the Lorenz curve, the Gini coefficient is a ratio of the area that lies between the line of equality and the Lorenz curve. Hence
If all people have non-negative income (or wealth, as the case may be), the Gini coefficient theoretically range from 0 to 1; it is sometimes expressed as a percentage ranging between 0 and 100. In the article teher are negative Gini value which means negative values of the variables. Perhaps this fact needs more explanation in the text because it is something unusuall and it is not straightforward for the ordinary people to interpret negative Ginis coefficent or Lorenz curves for which the inequality line is of the left side of the equality line.

Figure 1 and 2 has been recalculated using area per inhabitant as a sorting indicator. It produces only positive Gini indexes. The accompanying text has been revised. 16/12/2013 Teodora Brandmuller
