[Population-demographic structure of the population of Kursk district. Ethnic composition and age of marriage].

: When studying the marriage structure of the Kurskaya oblast population in 1987-1990, a positive marriage assortativeness with respect to ethnicity was found (K = 0.244). The Russian population exhibited panmixia; in the Ukrainian population, negative marriage assortativeness and panmixia prevailed; other ethnic groups were characterized by more or less pronounced positive marriage assortativeness. The ethnic compositions of raion (district) populations were determined by their geographic location and history. The parameter of marriage assortativeness with respect to age was r = 0.911; this value in the reproductive part of the population was r = 0.748. The age of contracting marriage in the raion populations depended on the extent of their urbanization.
