Kuolleisuustaulukko

Kuolleisuustaulukko, also known as a mortality table or life table, is a statistical tool used to represent the mortality of a population. It is a tabular representation of the number of individuals in a population who die at each age or age group, and the proportion of the population that survives to each age. The table is typically constructed using data from a census or a mortality survey.

The basic structure of a mortality table includes the following columns:

1. Age: The age group or specific age at which mortality is being considered.

2. Number of individuals: The number of individuals in the population at the beginning of the age group.

3. Number of deaths: The number of individuals who die within the age group.

4. Number of survivors: The number of individuals who survive to the end of the age group.

5. Probability of death: The proportion of individuals who die within the age group.

6. Probability of survival: The proportion of individuals who survive to the end of the age group.

Mortality tables are used in various fields, including actuarial science, demography, and epidemiology. They provide valuable information about the mortality patterns of a population, which can be used to make predictions about future mortality rates, to assess the impact of public health interventions, and to design insurance products and pension plans.

There are different types of mortality tables, including:

1. Period life table: A table that represents the mortality of a population over a specific period of time.

2. Cohort life table: A table that represents the mortality of a specific cohort of individuals over their lifetime.

3. Current life table: A table that represents the mortality of a population at a specific point in time.

Mortality tables are an essential tool for understanding and analyzing mortality patterns, and they play a crucial role in public health, insurance, and pension planning.
