GC Wealth Project Data Warehouse

The GC Wealth Project, a central project of the Graduate Center's Stone Center on Socio-Economic Inequality, is an effort aimed at expanding and consolidating access to the most up-to-date research and information on wealth, wealth inequalities, and wealth transfers and related tax policies, across countries and over time. The dataset consolidates most existing evidence on private wealth and undertakes a significant data harmonization effort. We supplement each data point with extensive metadata on methodology and add new data. The data warehouse features an extensive collection of information on the household wealth levels and balance sheets, along with distributional statistics from a wide range of sources. Moreover, it draws together data on wealth transfer tax revenues, and tax features such as rates, exemption thresholds, and tax schedules. The broad range of data sources in the warehouse allows users to assess the degree of heterogeneity of estimates, and how methodological choices affect measurement outcomes. The new data points and policy indicators also allow extending quantitative analysis of wealth and public policy. Version 1.2_SciDatar1 (Revised for peer review)This version incorporates revisions to the Version 1.2 of the data requested during the peer-review process at Scientific Data. Updates include corrections to metadata (access links), and minor metadata updates. We also add tables summarizing the source data. The scope, structure, and conceptual framework of the dataset remain unchanged.
