Abstract

This paper shows the results of estimating top income shares in Japan using the 2014 and 2019 household survey dataset and the newly aggregated tax dataset from income tax microdata following the Distributional National Accounts (DINA) Guidelines. The guidelines are presenting the concepts, data sources, and methods to keep consistency for international comparison and used for making data series in the World Inequality Database (WID). By following the DINA procedure, we combine the survey dataset and the newly aggregated income tax dataset for 2014 and 2019 using the method presented by Blanchet et al. (2022). In addition, we consider various types of incomes which are not included in the survey and tax datasets but are included in the Net National Income (NNI) concept. The main results by using the most recent Japanese survey and tax data show that the top 1% income share in Japan was 8.44%, and the top 10% income share was 33.79% in 2019, which are much lower than the results for the United States and France presented in the World Inequality Report 2022 (Chancel et al., 2021).
