Why will the world benefit from an aging population?
With aging comes great wisdom, life experience, and perspective. An older and aging population can still be an important workforce. An older population can still be an important income generator. And older populations can be an important source of social support for others within their cohort.
How an ageing population will change the world?
lSome populations will shrink in the next few decades. While world population is aging at an unprecedented rate, the total population in some countries is simultaneously declining. lFamily structures are changing. As people live longer and have fewer children, family structures are transformed, leaving older people with fewer options for care.
What are the factors that contribute to global aging?

How does caregiving affect a family?from sciencedirect.com
In 1998, Marks studied the effects of caregiving for children, spouses, parents, and other kin and non-kin among employed midlife workers. Caregiving was a strong predictor of high family to work spillover and stress for both men and women. In turn, the amount of work-family conflict employees experienced affected the extent to which caregiving resulted in distress, hostility, and poorer health. How do employed caregivers cope with significant care responsibilities for a senior or a chronically-ill family member? According to Statistics Canada data, many employees adapt their work schedules, while others take a period of unpaid leave, which can be quite problematic, especially for low-wage workers. Caregiving for an older family member is more likely to be a reason for withdrawal from the labor force among women than men. In 2002 more than 21% of retired women aged 45–64 who provided eldercare but only 8% of men caregivers who retired said that the need to provide care was one of the reasons they retired. Among currently employed caregivers, it is estimated that as many as 1 in 5 women and 1 in 10 men could retire sooner than planned because of caregiving responsibilities. These statistics are important early warning signals that policy makers’ interests in extending the number of years individuals work may be on a collision course with the realities of trying to maintain employment while providing eldercare. Pavalko and Henderson (2006) report that women are more likely to quit their jobs than to cut back or try to work things out with their employer, unless their employer has made it clear that flexibility is possible. In such cases, “women who report access to flexible hours had 50% greater odds of still being employed two years later than those who did not have access to this benefit” (Pavalko & Henderson, p. 366).
Why is environmental gerontology important?from en.wikipedia.org
Also, the environmental gerontology indicates the importance of the environment in active ageing. In fact, promoting good environments (natural, built, social) in ageing can improve health and quality of life and reduce the problems of disability and dependence, and, in general, social spending and health spending.
What are the measures for caregiving leave?from sciencedirect.com
In addition to providing flexibility to workers, other supportive measures that will need to be in place in countries which have not yet developed such initiatives, are provisions for paid caregiving leave similar to parental leave policies, homecare, respite services, financial assistance (especially for low-income caregivers and those who incur significant financial costs), and information and supports to enable employees to plan ahead and to access information and support in a timely fashion. Carers’ leave already exists in the UK and in a number of other European countries, but careful analysis of these policies, their take-up, and use is not available. Major studies in Canada and the US have begun to identify good business practices and appropriate policy supports to help ease the pressures of combining work and eldercare, which are also applicable to providing care supports for individuals with a seriously or acutely ill spouse/partner. Given current population trends and the number of employees already experiencing eldercare and family care concerns, further development of policies and practices should not be delayed. Care should also be taken to reduce the costs to women as primary caregivers and to low-income earners who are not covered under policies that could otherwise be more effective in promoting the integration of work and care responsibilities.
Why is population aging equated to individual aging?from sciencedirect.com
Because population aging is equated to individual aging all too often, one tends to highlight problems for aging societies, in particular problems related to the costs of health and pension programs for the elderly. On this subject some issues need to be clarified and some myths should be dispelled.
How does population aging affect long term care?from sciencedirect.com
Population aging has profound effects on the demand for long-term care. As life expectancy increases, the overall value of health increases ( Murphy and Topel, 2006 ). Although the increase in longevity has ambiguous theoretical effects on the demand for long-term care (if age-adjusted morbidity improves rapidly, for instance, then demand could decrease), overall there has been a strong increase in demand. There are more people who reach elderly ages. Elderly people live longer, spending more time in retirement. Not only does total demand increase, but the range of needs grow. Some elderly persons live relatively free from chronic illness ( Manton et al., 1997 ), but others can live for years with chronic illnesses that once proved fatal. Medical devices improve mobility. The result is not only increased demand but a wider range of needs.
What is the cohort component method?from population.un.org
In doing so, the Population Division used the cohort-component method (United Nations, 1956) to ensure internal consistency by age and sex and over time, and between the three demographic components of change (fertility, mortality and migration) and the enumerated population.
Why are demographic patterns important?from sciencedirect.com
Why are these demographic patterns important? Use of long-term care and medical services is high among older people, and an aging population will inevitably put growing pressure on care services. This can be illustrated by projections of needs and expenditure for England using the Personal Social Services Research Unit (PSSRU) model ( Wittenberg et al., 2006 ). The model has projected that the number of occupied residential places (in residential care homes, nursing homes, hospitals) would need to expand by 115% between 2002 and 2041 just to keep pace with demographic change, while care support for older people in their own homes would need to increase by 103%. But these needs could be much higher if the proportion of older people who are dependent increases (perhaps because people with high care needs survive into old age as a result of improvements in medical technology), or if quality of care improvements are demanded by future cohorts of service users, or family members are less able or willing to provide unpaid care for dependent older relatives (perhaps because of changing labor force participation patterns and geographical mobility).
How does international migration affect the ageing process?
In countries that are experiencing large immigration flows, international migration can slow the ageing process , at least temporarily, since migrants tend to be in the young working ages. However, migrants who remain in the country eventually will age into the older population.

Why are older people important?
Older persons are increasingly seen as contributors to development, whose abilities to act for the betterment of themselves and their societies should be woven into policies and programmes at all levels. In the coming decades, many countries are likely to face fiscal and political pressures in relation to public systems of health care, pensions and social protections for a growing older population.

The Plan of Action called for changes in attitudes, policies and practices at all levels to fulfil the enormous potential of ageing in the twenty-first century. Its specific recommendations for action give priority to older persons and development, advancing health and well-being into old age, and ensuring enabling and supportive environments.
When was the World Assembly on Ageing?

What are the risks of ageing?
There are many other social and economic risks that we can come to expect as the global population continues to age: 1 The Squeezed Middle: With more people claiming pension benefits but less people paying income taxes, the shrinking workforce may be forced to pay higher taxes. 2 Rising Healthcare Costs: Longer lives do not necessarily mean healthier lives, with those over 65 more likely to have at least one chronic disease and require expensive, long-term care. 3 Economic Slowdown: Changing workforces may lead capital to flow away from rapidly aging countries to younger countries, shifting the global distribution of economic power.

How does aging affect the ability to fight?
The majority of research concerns the influence of societal aging on willingness and ability to fight. Manpower and budget are the biggest concerns with population aging—namely, that there will not be enough of either. Some argue that aging states will be the most peaceful because they have lower capacity for conflict as defense spending is crowded out by spending on seniors. They surmise that aging societies have high per unit soldier costs as the number of age-eligible soldiers shrinks and the money invested in individual soldiers rises. States will therefore be wary of expending their valuable resources. Some also argue that aging states will be averse to military casualties because the personal and political costs of losing a child is higher the smaller the family (Brooks et al., 2019; Luttwak, 1994 ). Others, however, use power transition theory to argue that aging states may be more aggressive in the face of aging as a last gasp to grab global power (Sciubba, 2014a ). Along these lines, alliances could, to some degree, help states compensate for declining manpower by providing “strength in numbers” and shared investments in personnel-saving technologies, which allow them to project power even in the face of aging. Yet some argue that alliances like the North Atlantic Treaty Organization (NATO) are set to implode because of internal demographic changes, which weaken their ability to effectively respond to threats (Ceccorulli, Fassi, & Lucarelli, 2017 ).
Why does aging lead to more austere social spending?
Other studies use a completely different set of assumptions and argue that aging can lead to more austere social spending because of the pressure on the median voter, who is of working age, and their desire to avoid higher taxation to pay for generous spending on the elderly —this is what some have termed the “fiscal leakage” hypothesis (Razin & Sadka, 2007 ). Sometimes contesting pressures within a society can cancel each other out: Sanz and Velázquez ( 2007, p. 917) find that aging “is the main driving force of the growth of government spending, followed by relative prices and population” but other age groups work to counter increases in benefits to retirees. They go on to note that “institutional reforms have been successful at reducing the impact of ageing on pensions in recent years.” There is still much work to be done in this area, particularly if age divisions supplant class divisions in some postindustrial societies and as demographic aging reaches countries without democratic institutions, such that the size of voting blocs ostensibly matters less (Sciubba & Chen, 2017 ).
What is political demography?
Political demography studies often focus on the political power of various age groups and attempt to assess the degree to which intergenerational conflict is emerging as the sizes of age groups change and their demands on services like entitlements shift alongside.

What is the Decade of Healthy Ageing?
The Decade of Healthy Ageing (2021–2030) seeks to reduce health inequities and improve the lives of older people, their families and communities through collective action in four areas: changing how we think, feel and act towards age and ageism; developing communities in ways that foster the abilities of older people; delivering person-centred integrated care and primary health services responsive to older people; and providing older people who need it with access to quality long-term care.
What are some examples of supportive environments?
Supportive physical and social environments also enable people to do what is important to them, despite losses in capacity. The availability of safe and accessible public buildings and transport, and places that are easy to walk around, are examples of supportive environments. In developing a public-health response to ageing, it is important not just to consider individual and environmental approaches that ameliorate the losses associated with older age, but also those that may reinforce recovery, adaptation and psychosocial growth.

What are the challenges of aging?from amacad.org
The rapid aging of populations around the world presents an unprecedented set of challenges: shifting disease burden, increased expenditure on health and long-term care, labor-force shortages, dissaving, and potential problems with old-age income security. We view longer life spans, particularly longer healthy life spans, as an enormous gain for human welfare. The challenges come from the fact that our current institutional and social arrangements are unsuited for aging populations and shifting demographics; our proposed solution is therefore to change our institutions and social arrangements. The first section of this essay provides a statistical overview of global population aging and its contributing factors. The second section outlines some of the major challenges associated with widespread population aging. Finally, the third section of the essay describes various responses to these challenges, both current and prospective, facing individuals, businesses, institutions, and governments.

Impacts and Implications of an Ageing Population
Ageing is a demographic trend that has important consequences for the state, healthcare, education and, more generally, for the economic growth of a nation.
Advantages and Challenges of an Ageing Population
Rising proportions of older people can significantly change the makeup of a nation. This has different outcomes, both advantageous and disadvantageous.

The Implications of An Aging Population
The Demographic Debacle
- By 2050, there will be 10 billion peopleon earth, compared to 7.7 billion today—and many of them will be living longer. As a result, the number of elderly people per 100 working-age people will nearly triple—from 20 in 1980, to 58 in 2060. Populations are getting older in all OECD countries, yet there are clear differences in the pace of aging. For...
A Declining Workforce
- Globally, the working-age population will see a 10%decrease by 2060. It will fall the most drastically by 35% or more in Greece, Japan, Korea, Latvia, Lithuania, and Poland. On the other end of the scale, it will increase by more than 20% in Australia, Mexico, and Israel. Israel’s notably higher increase of 67%is due to the country’s high fertility rate, which is comparable to “baby boo…
Managing The Risks

The Squeezed Middle:With more people claiming pension benefits but less people paying income taxes, the shrinking workforce may be forced to pay higher taxes. 2. Rising Healthcare Costs: Longer lives do not necessarily mean healthier lives, with those over …
Pensions Under Pressure
- A pension is promised, but not necessarily guaranteed. Any changes made to existing government programs can alter the lives of future retirees entirely—but effective pension reforms that lessen the growing deficit are required urgently.
Live Long and Prosper
- As 2020 marks the beginning of the Decade of Healthy Ageing, the world is undoubtedly entering a pivotal period. Countries all over the world face tremendous pressure to effectively manage their aging populations, but preparing for this demographic shift early will contribute to the economic advancement of countries, and allow populations—both young and old—to live long and prosper.
