Genetic demography of the Kuznetsk Basin population: Changes in marriage assortativeness with respect to ethnicity and age in the Belovo City population with time

摘要

A genetic demographic study has been performed in the city of Belovo with the use of the data on marriages contracted there in 1970 and 1994-1999. Marriage assortativeness with respect to age has been found to be the strongest and remain unchanged during the lifetime of one generation (r = 0.730 in 1970 and r = 0.801 in 1994-1999). Monoethnic marriages were substantially more frequent than interethnic ones in the Belovo population during the period studied, although the ethnic marriage assortativeness considerably decreased (K = 0.386 in 1970 and K = 0.141 in 1994-1999). Panmixia has been observed in the Russian population of Belovo. Other Eastern Slavs (Ukrainians and Belarussians) are characterized by negative marriage assortativeness and panmixia; positive marriage assortativeness has been found in other ethnic groups.
