Dynamics of interethnic mixing in Yamal Nenets people (according to data on the marriage structure and the surname database)

Abstract

The article discusses the results of the mixation study of Yamal Tundra Nenets people from 1980 to 2019 within the context of their inclusion in inter-ethnic contacts with allochthonous ethnic groups, mechanisms of miscegenation and changes in population genetic structure. Two generations (the 1980s and 2010s) of Tundra Nenets from Yar-Sale rural settlement, Yamal district, YNAD were studied - a total of 8346 Nenets. Dynamics of structure of marriages and surnames were analyzed. Obtained data demonstrates a relatively low level of genetic and demographic transformations accumulated during the studied period. This can be traced, in part, when looking at the frequency of ethnically mixed marriages and the percentage of the new (“alien”) surnames integrated into the Nenets surname structure. We predict a gradual positive dynamic (i.e., increase) of these figures.
