Zusammenfassung:
In the absence of a wealth register, Belgian wealth inequality needs to be estimated. Here I apply the mortality multiplier approach to Belgian inheritance tax tabulations and administrative microdata, collectively covering 1935 to 2022. Belgian wealth inequality has strongly declined during the 20th century and seems relatively stable in recent years. I triangulate my estimates with national accounts aggregates and previous work on Belgian wealth inequality. The evolution of Belgian wealth inequality is in line with other European countries for which long-run estimates are available.
