What distinguishes WID.world’s national accounts data from the UN, the IMF, the World Bank, or other national accounts data providers?

This is fully explained in the country-specific papers. We provide a detailed and explicit description of our methodology and sources, so that other users can contribute to their improvement. the top 1%), they contributed to reveal new facts and refocus the discussion on rising inequality. Next, we include corrections for offshore wealth and offshore capital income, so that our series on foreign capital income inflows and outflows are consistent at the global level (e.g. The database, its documentation, as well as a data query and visualization app are available on this website.

More generally, it is becoming more and more critical to measure the inequality of income and wealth from a global perspective, and not simply at the country level. There are now more than 3,600 unique country-year observations in … Our series and methods should be viewed from the perspective of a long-term, cumulative, collaborative research process. The World Inequality Database ( WID.world) aims to provide open and convenient access to the most extensive available database on the historical evolution of the world distribution of income and wealth, both within countries and between countries. The World Inequality Database (WID.world) aims to provide open and convenient access to the most extensive available database on the historical evolution of the world distribution of income and wealth, both within countries and between countries. This allows us to release inequality estimates that are more reliable – from the bottom to the top of the distribution of income and wealth – and also that span over much longer periods.

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. In order to produce reliable estimates of wealth inequality, it is becoming increasingly critical to combine different sources in a consistent manner, including income tax data (using the capitalization method) and inheritance tax data (using the mortality multiplier method), following the pioneering work of A. B. Atkinson and Alan Harrison 1978, and extends it to many more countries and years. they sum to zero), which is typically not the case in existing databases.

(Source: United Nations World Income Inequality Database) The Gini-coefficient measures wealth distribution In addition to the WTID top income shares series, this first version of WID included an extended version of the historical database on the long-run evolution of aggregate wealth-income ratios and the changing structure of national wealth and national income first developed by T. Piketty and G. Zucman 2013, 2014 (see also T. Piketty, 2014, for an attempt to propose an interpretative historical synthesis on the basis of this new material and of the top income shares series). In this spirit, we also provide a new set of research tools for scholars, journalists, or any interested user in the production of their own inequality datasets. Over the past decades, the increase in economic inequalities was largely driven by a rise in income and wealth accruing to the top of the distribution. See in particular the « World National Accounts Series Methodology » (here) and the « Distributional National Accounts Guidelines » (there). A LONG-TERM, CUMULATIVE, COLLABORATIVE RESEARCH PROCESS.
