Life expectancy

<p>Life tables, also called mortality tables, illustrate both the average life expectancy and the potential schedule of population extinction. Life expectancy of a person at the age of x years is a prediction of future life expectancy. It informs how many years on average a person aged x completed would survive, if the currently observed mortality conditions were maintained for a sufficiently long time.</p> <p>The most frequently used and cited parameter is the newborn's life expectancy or shortly: life expectancy (denoted as e0 ). It is used to study changes in mortality over time and is also one of the measures of the health status of the population. It is also used for national (e.g. intervoivodship) and international comparisons.</p> <p>The following data is used to build complete life tables: • the number of people who died in a given year by age, • population by age group as of June 30 of a given year.</p> <p>The following data is used to build complete life tables:</p> <p>• the number of people who died in a given year by age,</p> <p>• population by age group as of June 30 of a given year.</p>
