dödlighetstabeller

Dödlighetstabeller, also known as mortality tables, are statistical tools used to represent the probability of death at different ages. They are fundamental in actuarial science, demography, and epidemiology, providing a basis for life insurance, pension calculations, and public health planning. These tables typically present age-specific mortality rates, which can be used to calculate life expectancy, annuity values, and other actuarial measures.

Mortality tables are constructed using historical or current mortality data, often from large populations. They can be based on various factors such as gender, geographic location, socioeconomic status, and health conditions. The most common type is the life table, which provides a comprehensive view of mortality patterns over a lifetime. Life tables typically include columns for the number of individuals alive at the beginning of each age interval, the number of deaths within each interval, and the probability of dying within each interval.

One of the earliest and most famous mortality tables is the Gompertz-Makeham law, which describes the human mortality rate as a function of age. This law has been widely used in actuarial science and demography. More recent developments include the use of advanced statistical methods and the incorporation of additional variables to improve the accuracy and applicability of mortality tables.

Mortality tables are essential for understanding and predicting mortality patterns, which is crucial for various applications in finance, healthcare, and social policy. They provide a standardized way to compare mortality rates across different populations and time periods, facilitating research and policy-making.
