What is life expectancy answer?
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.
An individual's work-life expectancy is a statistical measure of the length of time an individual is expected to participate in the workforce. Whether or not an individual is initially active in the workforce is a factor that influences an individual's work-life expectancy.
Life expectancy measures how long a person can expect to live. Quality of life can be measured in terms of living conditions, physical health, mental health, social relationships, level of independence, economic security, safety, or basic human rights.
Life expectancy is just an estimate based on the statistics of that population. It is what the experts would expect to happen. In contrast, life span is the length of time an individual person lives. It is the measure of the span of a person's life.
Life expectancy is the median age at death for a particular population group. For example, if a group of people have a life expectancy at birth of 70 years, half died before 70 and half survived beyond this age. Note that life expectancies are also determined for each age group, usually in 10-year increments.
Life expectancy is the key metric for assessing population health. Broader than the narrow metric of the infant and child mortality, which focus solely at mortality at a young age, life expectancy captures the mortality along the entire life course. It tells us the average age of death in a population.
Higher healthy life expectancy is strongly correlated with higher employment rates, particularly for men. On average, for every 10 percentage points higher the employment rate, healthy life expectancy is around 5 years higher.
The teaching domain is characterized by the longest life expectancy, i.e., 18.3 years for men and 23.1 years for women.
People who live in areas with high employment rates are more likely to live longer. And, there is a positive correlation between an area's employment rates and both men's and women's healthy life expectancy. Conversely, the healthy life expectancy of both men and women is negatively affected by economic inactivity.
Period life expectancy (PLE) is one of the most used summary indicators for the overall health of a population. It is based on the set of observed age-specific death rates, i.e., the number of deaths in a certain year and age group divided by the average number of people alive in this year and age group.
What factors affect life expectancy?
Significant factors in life expectancy include gender, genetics, access to health care, hygiene, diet and nutrition, exercise, lifestyle, and crime rates. Evidence-based studies indicate that longevity is based on two major factors, genetics, and lifestyle choices.
Life expectancy is the most commonly used measure to describe population health and reflects the overall mortality level of a population. Life expectancy measures how long, on average, a person is expected to live based on current age and sex-specific death rates.
Expert-verified answer
Life expectancy is statistical data of the average time of a person is expected to live, which is based on the year of their birth, current age and other factors too including gender. It is mean number of years of person going to live.
Female: 81.1 years - Average life expectancy of a US female (at birth). 5.0-year difference between average US female and male lifespan expectancy.
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, its current age and other demographic factors including gender.
It is estimated that about 25 percent of the variation in human life span is determined by genetics, but which genes, and how they contribute to longevity, are not well understood.
Globally, life expectancy has increased by more than 6 years between 2000 and 2019 – from 66.8 years in 2000 to 73.4 years in 2019.
The current life expectancy for U.S. in 2022 is 79.05 years, a 0.08% increase from 2021. The life expectancy for U.S. in 2021 was 78.99 years, a 0.08% increase from 2020.
Life expectancy at birth is derived from life tables and is based on sex- and age-specific death rates. Life expectancy at birth values from the United Nations correspond to mid-year estimates, consistent with the corresponding United Nations fertility medium-variant quinquennial population projections.
Generally, increased life expectancy has increased the risk of disease, disability, dementia and advanced ageing prior to death 3, 4.
Why is life expectancy used to measure development?
It is a measure that summarizes the mortality of a country, allowing us to compare it by generations and analyze trends. Its interpretation and meaning is even richer and can provide us with key information on the level of development of a country's welfare state.
The experiment confirms that working longer causes better health – specifically longer life expectancy. Men ages 62-65 who worked longer due to the policy change saw a two-month increase in life expectancy during their late 60s. This improvement could be more substantial if the impact is longer lasting.
A 2021 study on Occupation-Based Life Expectancy found that people working in non-skilled general, technical and transport domains lived on average 3.5 years less than those in academic professions. Those working in the transport sector had the shortest life expectancy, and teachers had the longest.
There is a strong evidence base showing that work is generally good for physical and mental health and well-being. Worklessness is associated with poorer physical and mental health and well-being. Work can be therapeutic and can reverse the adverse health effects of unemployment.
“Somewhere in the range of 40 to 50 hours per week is more than enough for most people,” says Randy Simon, Ph. D., a licensed clinical psychologist based in Montclair and Summit, New Jersey.

A 25-YEAR-OLD American with a university degree can expect to live a decade longer than a contemporary who dropped out of high school. Although researchers have long known that the rich live longer than the poor, this education gap is less well documented—and is especially marked in rich countries.
Studies on work and health have found that the quality and stability of work is a key factor in the work-health relationship: research finds that low-quality, unstable, or poorly-paid jobs lead to or are associated with adverse effects on health.
Unemployment causes stress, which ultimately has long-term physiological health effects and can have negative consequences for people's mental health, including depression, anxiety and lower self-esteem.
What is life expectancy? Answer: Life expectancy is the number of years an average person can expect to live, based on data.
What is life expectancy class 10th?
In general, life expectancy can be defined as the average age till which the people of a country are expected to live.
Life expectancy refers to the span of life that a person is supposed to live. On the basis of social infrastructure and immune system of a person the life expectancy is decided. For the developing countries it is quite low in between 65 to 70 years only whereas in developed countries it is near about 80 to 90 years.
Life Expectancy- It is a statistical measure which describes the average time an individual is expected to live. It is based on factors like the year of its birth, present age, gender etc. The life expectancy increases with age as the mortality rate is greater in childhood.
Answer: A substance needs to have some utility to be called a resource.
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, its current age and other demographic factors including gender.
Human resources are defined as a resource that refers to the number of people and the mental/physical capacity of people who are willing to work. The business sector especially treats human resource as one of the most valuable resources one can find.
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).
According to the latest WHO data published in 2015 life expectancy in India is: Male 66.9, female 69.9 and total life expectancy is 68.3 which gives India a World Life Expectancy ranking of 123.
The current life expectancy for India in 2022 is 70.19 years, a 0.33% increase from 2021. The life expectancy for India in 2021 was 69.96 years, a 0.33% increase from 2020. The life expectancy for India in 2020 was 69.73 years, a 0.33% increase from 2019.
Significant factors in life expectancy include gender, genetics, access to health care, hygiene, diet and nutrition, exercise, lifestyle, and crime rates. Evidence-based studies indicate that longevity is based on two major factors, genetics, and lifestyle choices.
