Life Expectancy And Comprehensive Utilization Of Guangdong Province

Assuming that the current probability of dying of each age remained unchanged,lifeexpectancy is the number of years that the population is expected to continue to live. A life table,which is also called a mortality table or actuarial table, is a table which shows, for each age, whatthe probability is that a person of that age will die before his or her next birthday ("probability ofdeath"). Firstly, we suppose that the mortality of every age is a constant. Under this hypothesis, wewill get the life expectancy for each age by related mathematical model method. Secondly, hepreparation of life table is an important research tool for population quality, population healthlevel and population characteristics. Life expectancy is the measure of a society’s level ofeconomic development and an important index of medical and health service level.In this paper, we forecast the average life expectancy of Guangdong province by theprediction model of population’s average life expectancy, which is based on the probability ofdying. The calculation of the probability of death is a key factor to predict the average lifeexpectancy of the population. Considering the uncertainty of future population mortality rate, inthis paper, we predict the life expectancy of the population by two different kinds of mortalitytypes. they are deterministic type and uncertainty type.This paper consists of five parts. Firstly, we introduced the general characteristics of thepopulation in Guangdong Province and its development process. Secondly, we quoted thedefinition of average life expectancy and introduced some related concepts. Based on the wholepreparation work. we got the appropriate model of the average life expectancy of the population,which relates to the calculation of the key indicators of population average probability of death inlife expectancy, namely, we need to find a suitable mathematical model to describe therelationship between the probability of dying and death rates. In the last part, we discussed andanalyses the impact of the aging problem and pension insurance problem, which are followed bythe extension of the average life expectancy. Correspondingly, we have offered somerecommendations and advices to solve these problems.
