The comparison of indicators based on market and on disposable income allows a first assessment of the redistributive role of taxes and transfers. The geographic breakdown used in the paper is defined according to the OECD TL2 regional classification, broadly corresponding to the first level of administrative subdivision in each country (NUTS2 regions in Europe, States in the Unites States and Mexico, Provinces and Territories in Canada, etc.). This regional breakdown is meaningful from a policy perspective, as these large regions have considerable responsibilities for policy implementation.
