Koreans of the south Ussury in 1879

This article presents a demographic analysis of the Korean population in the region during its initial development, family composition, and marital relations between Koreans and Chinese. The study statistically confirmed the consequences of a number of historical events in the region, as well as a local manifestation of the effect of 'Missing Women of Asia' among the Korean population in the period under study. It is possible to say that such a powerful historical source as the research work of Vislenev on the “foreign” population of the South-Ussuri region was for the first time subjected to a comprehensive study. We hope it will be widely introduced into the scientific research. The results obtained, in our opinion, can significantly expand our understanding of the first settlers in the territory of the Russian Far East, but also of technologies for adaptation of migrants in the new location as a whole.
