Sergeeva Christina Nikolaevna, Sorokina Inna Nikolaevna

The aim of the study was to study the genetic and demographic characteristics of 9 regional populations of the Belgorod region. Within the framework of this study, based on the analysis of 5127 marriage records, the main marriage and demographic indicators were established (the age of marriage in general in the population and in its reproductive part, the national composition of spouses, the main indicators of the Maleko isolation model were calculated) at the beginning of the 21st century. The variability of the level of local inbreeding (a) in regional populations (0.00012–0.00037) was established, which corresponds to similar indicators in the neighboring Kursk region and somewhat differs from Moscow and the Moscow region, as well as border Ukraine. The average age of marriage was 25 and 27 years for men and women, respectively. Despite the high migration influx of the population in the Belgorod region, the main nationality of those who entered into marriage is the Russian nationality.
