The administrative regulations introduced by the partitioning powers were enforced in the Polish lands under Prussian, Russian, and Austrian rule. These regulations included the methods of vital statistics registration, the language in which entries were recorded, and the types of data collected. Differences in registration pose significant challenges for contemporary researchers attempting to unify these records. Additionally, questions arise regarding the credibility and reliability of the registrations, which varied across the territories of the three partitions. Prussia had by far the most advanced statistical system. Strict adherence to deadlines for reporting marriages, births, and deaths, by both officials and ordinary citizens, undoubtedly contributed to the high quality of records maintained in Prussian-controlled territories. This paper aims to characterize the sources relating to causes of death in Poznań, then the capital of the Poznań Province in the 19th century, and to examine the diversity and validity of these sources, the quality and reliability of medical statistics, the development of the Poznań Historical Population Database, and, finally, the research opportunities this database enables. The study highlights the importance of a critical methodological approach to historical cause-of-death data. It demonstrates that, although imperfect, such sources can provide valuable insights into past health patterns and administrative practices when interpreted with linguistic, medical, and contextual sensitivity. The resulting database offers a foundation for further interdisciplinary research on historical epidemiology and urban demography.
