Abstract
This article presents a comprehensive bibliometric analysis of scholarly research on ethnic minorities in the Soviet Union over the period 2001–2025. The study is based on 484 peer-reviewed articles indexed in the Web of Science Core Collection, reflecting the expansion of structured academic metadata and the increasing scholarly interest in post-Soviet studies over the past two decades. The primary aim is to identify key thematic developments, patterns of international collaboration, and the intellectual structure of this interdisciplinary research field. The analysis employs VOSviewer software and integrates several bibliometric techniques, including keyword co-occurrence analysis, co-authorship network mapping, and bibliographic coupling. The dataset was carefully cleaned and standardized using a thesaurus approach to ensure consistency in keywords and author affiliations. This methodological framework allows for a systematic visualization of relationships between research topics, authors, and countries. The results reveal four major thematic clusters that define the field: (1) migration, diaspora, and identity transformation, focusing on acculturation and integration processes; (2) state governance, nationalism, and minority rights, emphasizing language policy and ethnopolitical dynamics; (3) public health, demographic inequality, and socioeconomic outcomes, highlighting disparities in well-being and population trends; and (4) localized case studies, particularly in the Baltic region, addressing religion, education, and minority integration at the regional level. The findings demonstrate a steady increase in academic output, particularly after 2015, indicating a growing global interest in Soviet minority issues. The United States, Israel, Russia, and Germany emerge as the leading contributors, while post-Soviet countries such as Ukraine, Estonia, and Georgia show increasing research activity and integration into international academic networks. The co-authorship and bibliographic coupling analyses further reveal strong transnational collaboration patterns and shared intellectual foundations across national research communities. Overall, the study provides a systematic overview of Soviet minority research, offering new insights into its thematic composition, geographic distribution, and interdisciplinary nature. It contributes to a deeper understanding of how academic discourse on minorities has evolved and highlights key directions for future research in postSoviet and comparative studies.
