Influence of the Mean Net Migration Rate on Change in the Crude Death Rate

Nika Maglaperidze, Ilia State University

In this paper we presented a substitution for the intensity of growth inside the decomposition formula for the change of crude death rate using the variable r-method. This substitution can also be used successfully in decomposition formulas for the another demographic indicators, which contains intensity of growth in any dimensional case. This substitution is useful when data about migration is not available. In our empirical example for Georgia we demonstrate such a substitution. By calculations we find out that net migration of Georgian males significantly increased the covariance term and consequently the change in the crude death rate for Georgian males from 1989 to 1994.
