Our team is currently working on an initial set of studies based on the NBP data. Once the results are published, we will make the NBP Dataset publicly available on this site. If you would like to be notified when it is launched, please contact ethnicgoods@ibei.org to join our mailing list.
A preview of a part of the NBP Dataset, covering the Soviet Union (USSR), is available here.
When using the data, please cite: vom Hau, Matthias, Juliette Crespin-Boucaud, Emre Amasyali, Chun-Ying Wu, Frank-Borge Wietzke, Andrei Tarasov, and Jan Schlebusch (2026) The Nation-Building Policies Dataset: USSR, available at https://nation-building-research.github.io/dataaccess.html.
Codebook
The codebook provides definitions and descriptions of every variable in the NBP Dataset, including response categories and how missing, “unknown,” or “not applicable” values are handled. It also offers a brief overview of the dataset’s purpose and scope and specifies the units of analysis and data structure (including key identifiers and how records are organized and linked). In addition, the codebook justifies group selection, discusses the underlying concepts and operationalization strategies, and details the sources and documentation standards used for coding. Finally, it explains the coding workflow and quality-assurance procedures alongside subsequent standardization measures, data-processing steps and consistency checks used to validate and harmonize the dataset.
