In nine of the sixteen rural raions and three small towns in Tomskaya oblast, marriage structure with regard to birth place and ethnicity of spouses was genetically and demographically studied by selectively analyzing marriage records from 1970-1985. Migration processes of high intensity were shown to be characteristic of rural and urban inhabitants of Tomskaya oblast. High values of the migration index (0.56 for rural raions and 0.75 for small towns) and low values of the local endogamy index (0.22 and 0.08, respectively) were obtained. Analysis of marriage assortativeness according to birth place and ethnicity of spouses, in total, demonstrated low but statistically significant estimates of marriage assortativeness. Subdivision of oblast populations was determined mainly by ethnicity.
