    Area of Science:

    • Demography
    • Gerontology
    • Public Policy

    Background:

    • Increasing life expectancy presents challenges to government pension systems.
    • Accurate mortality estimates are vital for forecasting the population size of the oldest age groups.

    Purpose of the Study:

    • To present novel approaches for mortality and population projections at advanced ages.
    • To improve the accuracy of forecasts concerning the oldest old population.

    Main Methods:

    • Utilized Swedish period life table data.
    • Applied two assumptions: log-linear mortality decline over time and exponential hazard rate growth with age.
    • Developed mortality projections for Swedish males and females over the next fifty years.

    Main Results:

    • Generated fifty-year mortality projections for Swedish males and females.
    • Demonstrated new methodologies for projecting mortality in advanced age groups.

    Conclusions:

    • The presented methods offer improved tools for understanding and forecasting mortality trends in older populations.
    • These projections are essential for the sustainability of government pension systems facing demographic shifts.
