Genetic Demographic Structure of the Lugansk (Ukraine) Population: Age,Ethnicity, Education,and Occupation

Data from marriage records from registry office archives of 1960, 1985, 1990, and 2000 have been used to calculate the genetic demographic parameters of the Lugansk city population. The population is mostly Ukrainian and Russian. In the years studied, Ukrainians accounted for 49.4, 44.0, 44.6, and 48.7% of the population and Russians, for 46.3, 52.1, 50.7, and 45.6%, respectively. The total proportion of the two ethnic groups decreased from 97.3 to 94.6% for 40 years. The marriage contingency coefficient (K) with respect to ethnicity decreased from 0.16 to 0.07 in the period between 1960 and 1985 and increased from 0.10 to 0.24 between 1990 and 2000. The frequency of interethnic marriages (48.4, 50.9, 52.0, and 60.0%, respectively, in the years studied) indicate that the outbreeding component has been constantly increasing in the Lugansk population. The marriage assortativeness indices (A′) for Ukrainians were 0.2, 4.8, 2.1, and 6.0% in 1960, 1985, 1990, and 2000, respectively. For pooled minor ethnic groups, A′ values in these years were 25.6, 12.4, 18.9, and 6.6%, respectively. The marriage contingency coefficient (K) with respect to occupation increased in the period between 1960 and 1990 (0.14, 0.16, and 0.19 in 1960, 1985, and 1990, respectively), and K with respect to education decreased (0.35, 0.30, and 0.26, respectively).
