Variation of surnames and migration in the Russian regions
The paper uses multidisciplinary approach implemented at the crossroads of geography, anthropology, demography and history. Based on phone subscriber data, we are trying to answer how migration influences the surnames variation in Russian regions. We found that the regions with a high variety of surnames are located within the Russian main belt of settlement, which has fostered a more active exchange and admixture of the population. Several regional cases are explored too.
