Forecasting Survival Probabilities Using Actuarial Life Tables

Abstract

The study examines forecasting survival probabilities using actuarial life tables, with emphasis on the application of mortality and survival information in estimating the likelihood that individuals will survive to specific ages or over defined periods. Survival probabilities are fundamental to actuarial science because they provide important information for assessing future insurance and pension obligations. Actuarial life tables organize mortality experience into age-specific measures that enable actuaries to estimate survival patterns and make informed projections about future population and policyholder outcomes. The study will investigate how actuarial life tables can be used to forecast survival probabilities across different age groups and periods. It will examine the relationship between mortality rates, survival rates, number of survivors, age distribution, and life expectancy. Particular attention will be given to how historical mortality experience can be used to estimate future survival probabilities and identify changes in survival patterns over time. The study will consider important actuarial measures and techniques, including probability of death, probability of survival, mortality rates, life expectancy, survival functions, and life table analysis. Historical mortality data will be examined to establish patterns that can support survival forecasting. The study will also consider the influence of mortality improvements, changes in life expectancy, and differences in age-specific mortality on the reliability of survival probability forecasts. A quantitative research approach will be adopted for the study. Relevant demographic and mortality data will be obtained from appropriate statistical, demographic, and actuarial sources. Descriptive statistics, mortality trend analysis, life table techniques, survival probability calculations, and appropriate forecasting methods will be used to estimate future survival probabilities. The resulting forecasts may be compared with observed mortality experience to assess the consistency and reliability of the actuarial estimates. The study is expected to reveal that actuarial life tables provide a useful basis for forecasting survival probabilities across different ages and time periods. The findings may indicate that declining mortality rates and improvements in life expectancy are associated with higher projected survival probabilities. The study may also demonstrate that variations in mortality experience between age groups can produce differences in survival forecasts, emphasizing the importance of accurate and current mortality data. The study is expected to provide useful information for actuaries, life insurance companies, pension administrators, policymakers, and other stakeholders involved in long-term financial planning. Accurate survival forecasts may support life insurance pricing, reserve estimation, annuity valuation, pension liability assessment, and mortality risk management. The findings may also assist actuarial practitioners in reviewing mortality assumptions and improving the reliability of projections used in financial decision-making. The study concludes that actuarial life tables provide an important foundation for forecasting survival probabilities and evaluating future mortality patterns. It is therefore recommended that actuarial practitioners regularly update life table assumptions using recent mortality experience and emerging longevity trends. Continuous monitoring of mortality changes and periodic evaluation of forecasting models are also recommended to improve the accuracy of survival probability estimates and strengthen long-term actuarial planning.
