Additionally, we will progressively include inequality series at the sub-national level whenever possible (series of top income shares for each state in the United States are already available, as well as for urban and rural China). In addition, there is extensive evidence – e.g. Finally, reliable series for the consumption of fixed capital (capital depreciation) estimates are not readily available for a large number of countries, so we combine various sources and develop new methods to derive consistent global series.
