LIFE TABLES Meaning and
Definition
-
Life tables refer to statistical tools used in demography and actuarial science to analyze the mortality and survival patterns of a population. They are commonly used to study the life expectancy and death rates of a group of individuals over a specific period, typically organized by age or time intervals.
Life tables consist of a comprehensive set of age-specific mortality rates, which provide a detailed picture of the probability of surviving or dying at each age. These rates are often collected from vital registration systems, such as birth and death records, and supplemented with data from censuses, national surveys, or other sources.
By using life tables, researchers can generate important demographic indicators such as life expectancy at birth, age-specific death rates, and probability of dying at each age interval. These indicators not only provide insights into the health and mortality patterns of a population but also serve as a basis for policy planning, public health interventions, and insurance calculations.
Life tables are particularly valuable for understanding population dynamics, forecasting future population growth, and estimating the impact of factors such as changes in healthcare, migration, or social conditions on mortality rates. They are widely used in various fields, including public health, social sciences, finance, and insurance, to analyze and compare mortality patterns across different populations and time periods.

Etymology of LIFE TABLES
The word "life tables" is derived from the combination of the words "life" and "tables".
- "Life": This term comes from the Old English word "līf", which means "existence" or "living being". It can be traced back to the Proto-Germanic word *lībą and the Proto-Indo-European root *leip-, which signifies "to remain, to be left".
- "Tables": This word is derived from the Latin word "tabula", which originally referred to a wooden board or plank. Over time, it came to encompass the idea of a written document or tablet on which information is recorded.
When these two words are combined, "life tables" refers to recorded or tabulated data that provides statistical information about the mortality rates and life expectancies of different populations.
