Dependency Ratio
The dependency ratio is an age-population ratio of those typically not in the labor force (the ''dependent'' part ages 0 to 14 and 65+) and those typically in the labor force (the ''productive'' part ages 15 to 64). It is used to measure the pressure on the productive population. Consideration of the dependency ratio is essential for governments, economists, bankers, business, industry, universities and all other major economic segments which can benefit from understanding the impacts of changes in population structure. A low dependency ratio means that there are sufficient people working who can support the dependent population. A lower ratio could allow for better pensions and better health care for citizens. A higher ratio indicates more financial stress on working people and possible political instability. While the strategies of increasing fertility and of allowing immigration especially of younger working age people have been formulas for lowering dependency ratios, future ...

Pensions Crisis
The pensions crisis or pensions timebomb is the predicted difficulty in paying for corporate or government employment retirement pensions in various countries, due to a difference between pension obligations and the resources set aside to fund them. The basic difficulty of the pension problem is that institutions must be sustained over far longer than the political planning horizon. Shifting demographics are causing a lower ratio of workers per retiree; contributing factors include retirees living longer (increasing the relative number of retirees), and lower birth rates (decreasing the relative number of workers, especially relative to the Post-WW2 Baby Boom). An international comparison of pension institution by countries is important to solve the pension crisis problem. There is significant debate regarding the magnitude and importance of the problem, as well as the solutions. One aspect and challenge of the "Pension timebomb" is that several countries' governments have a consti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Countries By Dependency Ratio
Dependency ratios are a measure of the age structure of a population. They indicate the proportion of individuals that are likely to be economically "dependent" on the support of others. Dependency ratios relate the numbers of children (ages 0–14) and the elderly (ages 65+) to the number of adults (ages 15–64). Changes in the dependency ratio provide an indication of potential social support requirements resulting from changes in population age structures. When fertility levels decline, the dependency ratio initially falls because the proportion of children decreases while the proportion of the population of working age increases. If fertility levels continue to decline, dependency ratios eventually increase because the proportion of the population of working age starts to decline and the proportion of elderly persons continues to increase. The ''total dependency ratio'' is the total numbers of the children (ages 0–14) and elderly (ages 65+) populations per 100 people of adul ...

Ageing
Ageing ( BE) or aging ( AE) is the process of becoming older. The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. In a broader sense, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species. In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes. Reaction time, for example, may slow with age, while memories and general knowledge typically increase. Ageing increases the risk of human diseases such as cancer, Alzheimer's disease, diabetes, cardiovascular disease, stroke and many more. Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. Current ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retirement
Retirement is the withdrawal from one's position or occupation or from one's active working life. A person may also semi-retire by reducing work hours or workload. Many people choose to retire when they are elderly or incapable of doing their job due to health reasons. People may also retire when they are eligible for private or public pension benefits, although some are forced to retire when bodily conditions no longer allow the person to work any longer (by illness or accident) or as a result of legislation concerning their positions. In most countries, the idea of retirement is of recent origin, being introduced during the late-nineteenth and early-twentieth centuries. Previously, low life expectancy, lack of social security and the absence of pension arrangements meant that most workers continued to work until their death. Germany was the first country to introduce retirement benefits in 1889. Nowadays, most developed countries have systems to provide pensions on retirement ...

Macroeconomic Problems
Macroeconomics (from the Greek prefix ''makro-'' meaning "large" + ''economics'') is a branch of economics dealing with performance, structure, behavior, and decision-making of an economy as a whole. For example, using interest rates, taxes, and government spending to regulate an economy's growth and stability. This includes regional, national, and global economies. According to a 2018 assessment by economists Emi Nakamura and Jón Steinsson, economic "evidence regarding the consequences of different macroeconomic policies is still highly imperfect and open to serious criticism." Macroeconomists study topics such as GDP (Gross Domestic Product), unemployment (including unemployment rates), national income, price indices, output, consumption, inflation, saving, investment, energy, international trade, and international finance. Macroeconomics and microeconomics are the two most general fields in economics. The United Nations Sustainable Development Goal 17 has a target to enh ...

Demographic Economic Problems
Demography () is the statistical study of populations, especially human beings. Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population. Demographic analysis estimates are often considered a reliable standard for judging the accuracy of the census information gathered at any time. In the labor f ...

Aging Of Japan
Japan has the highest proportion of elderly citizens of any country in the world. According to 2014 estimates, about 38% of the Japanese population is above the age of 60, 25.9% are age 65 or above, a figure that increased to 29.1% by 2022. People aged 65 and older in Japan make up a quarter of the total population, and are estimated to reach a third by 2050. The aging of Japanese society, characterized by sub-replacement fertility rates and high life expectancy, is expected to continue. Japan had a post-war baby boom between 1947 and 1949, followed by a prolonged period of low fertility. These trends resulted in the decline of Japan's population beginning in 2011. In 2014, Japan's population was estimated to be 127 million; this figure is expected to shrink to 107 million (16%) by 2040 and to 97 million (24%) by 2050, should the current demographic trend continue. A recent global analysis found that Japan was one of 23 countries which could see a total population decline o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ageing Of Europe
The ageing of Europe, also known as the greying of Europe, is a demographic phenomenon in Europe characterised by a decrease in fertility, a decrease in mortality rate, and a higher life expectancy among European populations. Low birth rates and higher life expectancy contribute to the transformation of Europe's population pyramid shape. The most significant change is the transition towards a much older population structure, resulting in a decrease in the proportion of the working age while the number of the retired population increases. The total number of the older population is projected to increase greatly within the coming decades, with rising proportions of the post-war baby-boom generations reaching retirement. This will cause a high burden on the working age population as they provide for the increasing number of the older population. Throughout history many states have worked to keep high birth rates in order to have moderate taxes, more economic activity and more tro ...

Societal Collapse
Societal collapse (also known as civilizational collapse) is the fall of a complex human society characterized by the loss of cultural identity and of socioeconomic complexity, the downfall of government, and the rise of violence. Possible causes of a societal collapse include natural catastrophe, war, pestilence, famine, economic collapse, population decline, and mass migration. A collapsed society may revert to a more primitive state, be absorbed into a stronger society, or completely disappear. Virtually all civilizations have suffered such a fate, regardless of their size or complexity, but some of them later revived and transformed, such as China, India, and Egypt. However, others never recovered, such as the Western and Eastern Roman Empires, the Maya civilization, and the Easter Island civilization. Societal collapse is generally quick but rarely abrupt. Anthropologists, (quantitative) historians, and sociologists have proposed a variety of explanations for the collap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sub-replacement Fertility
Sub-replacement fertility is a total fertility rate (TFR) that (if sustained) leads to each new generation being less populous than the older, previous one in a given area. The United Nations Population Division defines sub-replacement fertility as any rate below approximately 2.1 children born per woman of childbearing age, but the threshold can be as high as 3.4 in some developing countries because of higher mortality rates., Introduction and Table 1, p. 580 Taken globally, the total fertility rate at replacement was 2.33 children per woman in 2003. This can be "translated" as 2 children per woman to replace the parents, plus a "third of a child" to make up for the higher probability of males born and mortality prior to the end of a person's fertile life. In 2020, the average global fertility rate was around 2.4 children born per woman. Replacement-level fertility in terms of the net reproduction rate (NRR) is exactly one, because the NRR takes both mortality rates and sex r ...

Generational Accounting
Generational accounting is a method of measuring the fiscal burdens facing current and future generations. Generational accounting considers how much each adult generation, on a per person basis, is likely to pay in future taxes net of transfer payments, over the rest of their lives. Laurence Kotlikoff's individual and co-authored work on the relativity of fiscal language demonstrates that conventional fiscal measures, including the government's deficit, are not well defined from the perspective of economic theory. Instead, their measurement reflects economically arbitrary fiscal labeling conventions. "Economics labeling problem," as Kotlikoff calls it, has led to gross misreadings of the fiscal positions of different countries. This starts with the United States, which has a relatively small debt-to-GDP ratio, but is, arguably, in worse fiscal shape than any developed country. Kotlikoff's identification of economics labeling problem, beginning with his 1984 ''Deficit Delusion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
