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.
The life expectancy is shown separately for males and for females, as well as a combined figure. Several non- sovereign entities and territories are also included in this list. The figures reflect the quality of healthcare in the countries listed as well as other factors including HIV infections.
The Physical Quality of Life Index (PQLI) is an attempt to measure the quality of life or well-being of a country. The value is the average of three statistics: basic literacy rate , infant mortality, and life expectancy at age one, all equally weighted on a 1 to 100 scale.
The life expectancy in some states has fallen in recent years; for example, Maine's life expectancy in 2010 was 79.1 years, and in 2018 it was 78.7 years. The Washington Post noted in November 2018 that overall life expectancy in the United States was declining although in 2018 life expectancy had a slight increase of 0.1 and bringing it to ...
One quality-adjusted life year (QALY) is equal to 1 year of life in perfect health. [2] It combines two different benefits of treatment—length of life and quality of life—into a single number that can be compared across different types of treatments. For example, one year lived in perfect health equates to 1 QALY.
It is computed by subtracting the probable duration of bed disability and inability to perform major activities from the life expectancy. The data for calculation is obtained from population surveys and period life table. The Sullivan's index collects mortality and disability data separately, and this data is almost often readily available. The ...

The estimates are either for one year of additional life or for the statistical value of a single life. $50,000 per year of quality life (the "dialysis standard", [39] which had been a de facto international standard most private and government-run health insurance plans worldwide use to determine whether to cover a new medical procedure) [40]
