Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth (LEB, or in demographic notation e 0, where e x denotes the average life remaining at age x). This can be defined in two ways.
Life tables can be extended to include other information in addition to mortality, for instance health information to calculate health expectancy. Health expectancies such as disability-adjusted life year and Healthy Life Years are the remaining number of years a person can expect to live in a specific health state, such as free of disability .
Another statistic that can be obtained from a life table is life expectancy. e x {\displaystyle \,e_{x}} is the curtate expectation of life for a person alive at age x {\displaystyle x} . This is the expected number of complete years remaining to live (you may think of it as the expected number of birthdays that the person will celebrate).

To calculate life expectancy, you need to use Table 1 (for males) or Table 2 (for females) and use the data in the 0% column. So for a 45 year old female, using Table 2 you would look down the first column to find 45 and then across to the 0% column which gives a figure of 43.93.
Life expectancy in the U.S. is projected to increase from 78.3 years in 2022 to 79.9 years in 2035 and to 80.4 years in 2050 for all sexes combined, researchers said.
Years of potential life lost (YPLL) or potential years of life lost (PYLL) is an estimate of the average years a person would have lived if they had not died prematurely. [1] It is, therefore, a measure of premature mortality. As an alternative to death rates, it is a method that gives more weight to deaths that occur among younger people.
