title: [Multiregional approaches in demography].
abstract: "Regional populations and their migrations are analysed as a system of populations.  Such a system can be studied by multiregional models constructed on the basis of the multiregional approach.  The results thus achieved may substantially differ from those received by the conventional approach.  The theoretical formulations are illustrated by empirical studies of the rural and urban population of Bulgaria in 1960-1982."  (summary in ENG, RUS)
