The models of age-specific mortality rates and their patterns from female total population counts

Abstract

If net migration is negligible, population change in a country is governed by an increase due to births and a decrease due to deaths. This study focuses on the mortality of female population based on their total fertility rates. It develops a simple method to analyze population data with the aim to estimate age-specific mortality models for 54 countries in the world and identify a similar pattern among them. Specifically, the method involves estimating the mortality rates of those countries with negligible net age-specific migration to form the common models. These models are then applied to other countries by matching mortality at older ages to verify similar patterns. The results show three different mortality models which imply the differences in the mortality patterns between the countries studied.
