Preston's work has also contributed to the broadening of the definition of economic development. [3] Gary Becker et al. have included longevity in a more general welfare measure and have illustrated that increases in life expectancy have made up a large portion of increases in overall global welfare since the 1960s.

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 value of life is an economic value used to quantify the benefit of avoiding a fatality. [1] It is also referred to as the cost of life , value of preventing a fatality ( VPF ), implied cost of averting a fatality ( ICAF ), and value of a statistical life ( VSL ).
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
Longevity may refer to especially long-lived members of a population, whereas life expectancy is defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts).
The concept of human development expands upon the notion of economic development to include social, political and even ethical dimensions.Since the mid-twentieth century, international organisations such as the United Nations and the World Bank have adopted human development as a holistic approach to evaluating a country’s progress that considers living conditions, social relations ...
Labour economics seeks to understand the functioning and dynamics of the markets for wage labour. Labour is a commodity that is supplied by labourers, usually in exchange for a wage paid by demanding firms.
The safety benefit is the gain in life expectancy at birth, or life extension expected upon implementation of the program. The cost effects must also be evaluated, measured as the effect on the real gross domestic product per person (with refinements that could include correction for purchasing power parity for international comparisons).
