Question

life expentancy of death indicates the number of years born in expected to live ( correct the statement )​

Answer 1

Explanation:

The term “life expectancy” refers to the number of years a person can expect to live. By definition, life expectancy is based on an estimate of the average age that members of a particular population group will be when they die.

Answer 2

Answer:

Life expectancy at birth is the total person-years lived beyond exact age 0 (newborns - column 5 - Tx) divided by the number of newborns (100,000).

Explanation:

Life expectancy at age x can be obtained by dividing the total person-years lived beyond exact age x (column 5 - Tx) by the number of survivors at exact age x (column 2 - Ix). The statistic “Life expectancy at birth” actually refers to the average number of years a newborn is expected to live if mortality patterns at the time of its birth remain constant in the future. In other words, it’s looking at the number of people of different ages dying that year, and provides a snapshot of these overall “mortality characteristics” that year for the population.
