Technical Note
WIID Companion (May 2021): global income distribution

This document is part of a series of technical notes describing the compilation of a new companion database that complements the World Income Inequality Database (WIID). This technical note describes the construction of the global distribution companion datasets, version 31 May 2021.

While previous technical notes described the selection of country income distribution series and the integration and standardization process to overcome the heterogeneity in original welfare concepts and other methods, I describe here all the necessary additional steps and assumptions made to construct the global dataset.
