Definition:

The values of these functions are calculated useing of the number of deaths (in a given period, usually a year) and population by sex and age (in the middle of the given period). Life expectancy tables are used i.a. in to assess the health of the population. Trends in mortality changes, determined on the basis of life expectancy tables, are used in population projections.
