General analysis of the demographic dynamics components

The article deals with methodological and methodical issues of constructing a system of demographic indicators to characterize the general balance of population movement. It makes a distinction between the notions of population dynamics and demographic development. There are proposed new indicators of intensity and correlation characterizing the results of differently directed action of the components of population demographic movement. By analogy with vital rates, depopulation and efficiency of migration ties the authors introduce coefficient of demographic movement of population (Kdd). This index makes it possible to compare in a relative form two differently directed processes. One of these processes including mortality and emigration leads to decrease in the number of resident population of a territory. The other one including fertility and immigration leads to its increase. At the preliminary stage of analysis this index may give a complex characteristic in a relative form of total reproduction-migration effect of the population movement in a certain territory. The authors developed the methods for integrating the input of two relative characteristics of the general population movement - coefficient of depopulation and co-efficient of efficiency of migration ties into a resulting index - coefficient of demographic movement of population.
