The authors would like to thank Romain Duval, Jqrgen Elmeskov, Michael Forster, Jean-Marc Fournier, Kaja Fredriksen, Isabell Koske, Stephen Matthews and Jean-Luc Schneider for their useful comments and suggestions, Chantal Nicq for meticulous statistical work and Susan Gascard for excellent editorial support. These allow comparing 24 inequality dimensions for each country with the OECD average and identifying how these inequality dimensions map into inequality of household disposable income. The country profiles reveal that inequality of household disposable income does not have the same origins. In some countries, wage dispersion among those working is an important factor (e.g. the United States) while in others, the non-employment rate and/or inequality in capital income are driving inequality in HDI (e.g. Italy).
