Why Measure Life Expectancy
Life expectancy is an important aspect of demography. It highlights the characteristics and future trends of a given population. It is one of the tools policymakers use in measuring a nations Human Development Index. Countries with higher life expectancies score higher HDI than countries with lower life expectancies. Apart from HDI, it also helps in describing an areas physical quality of life. Populations with high average life expectancies are assumed to be enjoying better life because they have access to essential facilities, like hospitals.
Life expectancy also helps in implementing social support programs such as pension and social security funds. Knowing future trends in life expectancy enables governments to forecast the number of recipients likely to benefit and the amount to allocate for these social programs. Health experts can also consider life expectancy when choosing a health intervention strategy.

Access To Health Services
|
There is uneven access to health care on a local, regional, national and international level. Some countries have free health care for all the population, but an increasing number have insurance based schemes, or require payment for treatment. A raw figure is the number of people per doctor, or health worker or hospitals, or hospital beds. There may also be the use of figures relating to the number of doctors per 10 000 of the population. It is worth noting that the age structure of an area can impact on the accuracy of the figure. Some countries are understood to have lower coverage than is required for adequate health care. An additional figure is health expenditure per capita. Health services that are referred to here can include:

Countries With Lowest Life Expectancy
Most African countries and some developing countries globally have lower life expectancies for several reasons. However, the major contributing factor is inadequate access to healthcare. Most households have low incomes or financial resources to access proper healthcare. Besides access to healthcare, widespread of diseases such as HIV, cancer, malaria, and diabetes affect the quality of life and life expectancy in most African xountries.
In Afghanistan, apart from lack of adequate health care and malnutrition, constant conflicts, and wars contribute to high death rates and lower life expectancy.

How Geography Changes Life Expectancy For Americas Poorest
America’s poorest citizens have shorter lifespans than wealthier Americans, and new research finds that gap is growing. But the study also found that the poor who live in affluent and highly educated cities live longer than those who live in other areas. Judy Woodruff learns more from Raj Chetty of Stanford University.
The Gap In Life Expectancy At Birth Between Local Areas Of The Uk Was 113 Years For Males And 87 Years For Females In 2017 To 2019
There were large spatial gaps in life expectancy at birth across the UK . In England in 2017 to 2019, there was a 10.5-year gap in male life expectancy at birth between the local area with the highest, Westminster , and the area with the lowest, Blackpool . In Scotland, this gap was smaller at 6.9 years between East Dunbartonshire and Glasgow City . In Northern Ireland, the gap was 4.1 years between Lisburn and Castlereagh and Belfast . In Wales, the gap was 4.9 years between Monmouthshire and Blaenau Gwent . Overall, for the UK, the difference was 11.3 years between Westminster, with the highest life expectancy at birth, and Glasgow City, with the lowest.
For females, the local area gap in life expectancy at birth in England was 7.7 years between Westminster and Blackpool , meaning Blackpool was the lowest in England for males and females. In Scotland, the gap stood at 5.5 years between East Renfrewshire and Glasgow City . In Northern Ireland, the gap was 2.5 years between Lisburn and Castlereagh and Belfast . In Wales, the gap was 4.0 years between Monmouthshire and Blaenau Gwent . Overall, for the UK, the difference was 8.7 years between Westminster and Glasgow City. Table 2 shows the top and bottom five local areas with the highest and lowest life expectancies at birth for males and females.

Analysis Of Mortality And Life Expectancy At Birth
The independent effects of region i and deprivation quintile j on life expectancies at birth eij were evaluated by linear regression, weighted by the estimated populations from which the life tables were calculated. Region and deprivation were modelled as categorical variables. When the interaction between geography and deprivation was examined, deprivation quintile was modelled as a quadratic term, which provided a close fit to the relation predicted by the categorical model .
The impact of the intra-regional socioeconomic inequality upon regional life expectancy was also examined with a GINI coefficient. As deprivation data were not available for individuals, the coefficients were computed using the income domain score for the ward as a proxy for the income deprivation of people living in that ward. Population weighted linear regression of the resulting coefficients upon sex specific life expectancies for each region ei was performed.

presents the average change in e50 for each population as a whole and for the upper and lower 50 percent of its geographic distribution between 1980 and 2000, as well as the value of the convergence effect , both in absolute level and as a fraction of the total change over this time period. The table shows that between 1980 and 2000 all areas in the study improved their level of e50 and that, except for Japan, men benefited more than women from the decline in mortality at older ages ). also shows that the United States exhibited the smallest progress in e50 compared with the other countries in the study. Although the intercountry gap was relatively small for men, it was quite sizeable for women, with average annual gains of less than 3 additional weeks of life in the United States compared with more than 1 month in Canada, nearly 2 months in Western Europe as a whole, 3 in Germany, and 4 in Japan. Male e50 increased by somewhat less than 2 months per calendar year in the United States, which is not far from the gains achieved in the other areas .

Worldwide Variations In Life Expectancy
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 expectancies are available for over 200 populations ranging from China to the tiny sovereign states of Andorra and San Marino. As shown in Table 1, life expectancy at birth for males and females combined range from 33.22 years for Swaziland to 83.51 years for Andorra .
Consistent with findings that a good environment and SES promote longevity, most of the longest living populations are found in highly developed populations with superior sanitation, education, and health care. The worst life expectancies are found in Africa with its lower economic development and very high rate of mortality from HIV/AIDS infection. The top 10 populations in terms of descending life expectancy are Andorra, Macau, San Marino, Singapore, Hong Kong, Japan, Sweden, Switzerland, Australia, and Guernsey . .

What Is Life Expectancy
Life expectancy is the age a person can expect to live based on the statistical average for an area. It varies by location and by era. For example, in the Bronze age, you could expect to live to 26 years. However, things have changed significantly since then. According to the World Health Organisation, 72.0 years was the average life expectancy at birth of the global population in 2016.
Preservation Of Oceanic Plateaus
The life expectancy of oceanic crust, from formation at a mid-ocean ridge to recycling into the asthenosphere at a subduction zone, is of the order of 150200 Ma. Consequently, the oldest in situ oceanic plate is the Jurassic crust of the western Pacific . However, since oceanic plateaus are much more buoyant than oceanic crust of normal thickness formed at a mid-ocean ridge, they have a greater potential to resist subduction and, instead of being completely recycled back into the mantle, the upper layers can be peeled off and accreted on to island arcs and active continental margins . The net result is that oceanic plateaus are more likely to be preserved in the geological record than normal oceanic crust.

Annex 12b Use Of Principal Components For Creating Graphical Ellipses
As illustrated here in and , male and female values of life expectancy at age 50 for a given time period have a strong positive correlation across states and counties of the United States An efficient means of characterizing the two-dimensional distribution of male-female values is to draw ellipses that contain most or all of the data points. A simple method for creating such ellipses in a different application was described by . Here, we employ an alternative approach based on principal components analysis .
In words, we begin by centering the data points around their mean values, identifying their two principal axes and projecting the points onto the new basis , and then rescaling each point using standard deviations of projected abscissa and ordinate values. This series of calculations turns the original ellipsoidal scatterplot into a circular collection of points centered on the origin. To reduce the influence of outliers, we approximate the circular distribution while ignoring the outer 10 percent of data points that is, we find a minimum radius r such that a circle with this radius contains 90 percent of the observed points. This centering, projecting, and scaling process is then reversed, so that the points on the circle with radius r are remapped so that they are comparable to the original values of male and female life expectancy, forming an ellipsoid that contains 90 percent of the data points.

What’s The Difference In Life Expectancy Between Males And Females
Females have always lived longer than males, but the gender gap in 1841 was relatively small because of the high prevalence in the 19th century of diseases that killed both sexes indiscriminately. In the late 19th and early 20th centuries the gender gap in life expectancy started to widen, peaking at 6.3 years by 1971 . Reasons for the widening gender gap included poor working conditions and smoking among males in contrast to improved life chances for females, for example, lower risk of dying in childbirth and from tuberculosis, which affected women more than men.
The gender gap narrowed from the 1970s, to 3.7 years in 2019, with mortality falling faster in males than females because of decreases in smoking and mortality from cardiovascular diseases. However, in 2020 and 2021 the gender gap widened to 4 years because mortality rates from Covid-19 were higher in males than females.

What Explains The Differences
Much of the difference might be attributed to poverty. This leads to poor diet, fewer opportunities for exercise and lack of access to health care. Certain other countries such as Australia have done far more to provide preventive health care to a large portion of the population and to support people in changing unhealthy behaviors such as smoking or inactivity.
Life expectancy has dropped sharply in Kentucky and is low in central Appalachia, the Mississippi Delta and the Dakotas. Places where life expectancy has increased include the District of Columbia, Loudoun County, Virgina, Manhattan, Brooklyn, San Francisco and parts of Alaska.
