The aging of society

Overview[ edit ] Population aging is a shift in the distribution of a country's population towards older ages. This is usually reflected in an increase in the population's mean and median agesa decline in the proportion of the population composed of children, and a rise in the proportion of the population composed of elderly.

Population ageing is widespread across the world. It is most advanced in the most highly developed countries, but it is growing faster in less developed regions, which means that older persons will be increasingly concentrated in the less developed regions of the world. The corresponding figures for the world as a whole are 24 in29 inand 36 in For the less developed regions, the median age will go from 26 in to 35 in An increase in longevity raises the average age of the population by increasing the numbers of surviving older people.

A decline in fertility reduces the number of babies, and as the effect continues, the numbers of younger people in general also reduce. Of these two forces, it is declining fertility that is the largest contributor to population ageing in the world today.

Because many developing countries are going through faster fertility transitions, they will experience even faster population ageing than the currently developed countries in the future.

In a nutshell

The rate at which the population ages is likely to increase over the next three decades; [8] however, few countries know whether their older populations are living the extra years of life in good or poor health.

A " compression of morbidity " would imply reduced disability in old age, [9] whereas an expansion would see an increase in poor health with increased longevity. Another option has been posed for a situation of "dynamic equilibrium".

Canada has the highest per capita immigration rate in the world, partly to counter population ageing. Howe Institutea conservative think tankhas suggested that immigration cannot be used as a viable mean for countering population ageing.

Demographers Peter McDonald and Rebecca Kippen comment, "[a]s fertility sinks further below replacement level, increasingly higher levels of annual net migration will be required to maintain a target of even zero population growth".

The more developed countries also have older populations as their citizens live longer. Less developed countries have much younger populations. An interactive version of the map is available here. Asia and Europe are the two regions where a significant number of countries face population ageing in the near future.

The Oxford Institute of Population Ageing is an institution looking at global population ageing. Its research reveals that many of the views of global ageing are based on myths and that there will be considerable opportunities for the world as its population matures.

The Institute's Director, Professor Sarah Harper highlights in her book Ageing Societies [16] the implications for work, families, health, education, and technology of the ageing of the world's population.

Most of the developed countries now have sub-replacement fertility levels, and population growth now depends largely on immigration together with population momentum, which arises from previous large generations now enjoying longer life expectancy.

Of the roughlypeople who die each day across the globe, about two thirds—, per day—die of age-related causes. Dependency ratioGenerational accountingand Pensions crisis The economic effects of an aging population are considerable. Older people have higher accumulated savings per head than younger people, but spend less on consumer goods.

Depending on the age ranges at which the changes occur, an aging population may thus result in lower interest rates and the economic benefits of lower inflation. Because elderly people are more inflation averse, countries with more elderly tend to exhibit lower inflation rates [18].

Some economists Japan see advantages in such changes, notably the opportunity to progress automation and technological development without causing unemployment. They emphasize a shift from GDP to personal well-being. However, population aging also increases some categories of expenditure, including some met from public finances.

The largest area of expenditure in many countries is now health carewhose cost is likely to increase dramatically as populations age. This would present governments with hard choices between higher taxesincluding a possible reweighing of tax from earnings to consumption, and a reduced government role in providing health care.

However, recent studies in some countries demonstrate the dramatic rising costs of health care are more attributable to rising drug and doctor costs, and higher use of diagnostic testing by all age groups, and not to the aging population as is often claimed. Social security systems have also begun to experience problems.

Earlier defined benefit pension systems are experiencing sustainability problems due to the increased longevity. The extension of the pension period was not paired with an extension of the active labour period or a rise in pension contributions, resulting in a decline of replacement ratios.

Also, the Environmental gerontology indicates the importance of the environment in active aging [28] [29] [30].

In fact, promoting good environments natural, built, social in aging can improve health and quality of life, as well as reduce the problems of disability and dependence, and, in general, social spending and health spending.Network chair, John W.

Rowe, MD, presented a summary of the Network’s work on the challenges and opportunities of an Aging Society and moderated a panel of experts that included Network member, James Jackson, PhD, on social influences, interventions and impacts.

In short, the society comes to be more and more like an aged person as its population gets aged. The society gets less adventurous, less likely to make serious mistakes and also less likely to .

Gerontologists investigate age, aging, and the aged. Gerontologists study what it is like to be an older adult in a society and the ways that aging affects members of a society. As a multidisciplinary field, gerontology includes the work of medical and biological scientists, social scientists, and even financial and economic scholars.

Aging has a significant impact on society. People of different ages tend to differ in many aspects, such as legal and social responsibilities, outlooks on life, and self-perceptions.
