This article introduces a newly constructed dataset (i.e. the Tafel v-bis Dataset) containing summary information for all Dutch citizens who died in 1921 and were subject to inheritance taxation. This dataset provides personal and socio-economic information on 24,263 individuals, including their total wealth, age, profession, residence and marital status at their time of death. Consequently, this dataset can be useful for researchers stemming from various academic disciplines. The article first discusses the range of possible uses of the dataset. Then the authors explain how they constructed the dataset and provide the necessary criticism regarding the underlying source material. The dataset is available via the Utrecht University data platform, yoda.
