[Assortative mating in the population of a modern city]

An investigation of the population of modern Siberian city Angarsk was carried out. The sample consisted of 13746 individuals in the age interval from 21 to 60 years old. The population comprises more than 40 nationalities. The percentage of Russians, Ukrainians, Buryats, Byelorussians and Tatars in this population is 86.37, 5.35, 1.91, 1.65 and 1.46, respectively. The incidence of other nationalities does not exceed 1%. Analysis of the distances of birth places for married couples demonstrated the predominance of those in which husband and wife had come from different administrative regions of the country. This implies a significant impact of migration on formation of the new city population. A new qualitative approach to the assessing of assortative mating considering the nationality is presented and it is discovered that assortative mating on the basis of national belonging takes place in all the nationalities taken into analysis: in Russians, Ukrainians, Buryats, Byelorussians and Tatars.
