1.3 Population challenges and opportunities Flashcards
What changes in population did HICs experince during the 20th century?
-Average family size and
-The proportion of people surviving to an older age, giving rise to the phenomenon of an ageing population
What changes did LICs and middle-income countries experience in the 20th century?
-Changing social attitudes towards the role of women in society.
-This has affected the sex ratio of some societies.
What is an ageing population?
A population structure where the proportion of people aged 65 and over is high and rising.
What causes an ageing population?
Increasing life expectancy and can be further exaggerated by the effect of low birth rates.
An ageing population is also called a ___
‘Greying’ population
What is the sex ratio?
The relative proportions of men and women in a society’s population
In what countries is life expectancy now 80 years or higher?
Japan, Iceland, Italy, Australia, Germany, and many other countries
How is the proportion of eldely citizens expected to change in HICs as opposed to in MICs?
In the future, the proportion of elderly citizens in developed countries will grow higher still, while most middle-income countries will also begin to experience the effects of widespread ageing.
Example of how the number of elderly people in society is expected to change in the future
Globally, the number of older persons aged over 60 is expected to exceed the number of children aged under 15 for the first time by around 2050, helped significantly by the long-term legacy of China’s one-child rule (which left the world’s largest nation of 1.3 billion people with its own greying ‘time-bomb’).
Causes of an ageing population
-Increasing life expectancy (exacerbated by low birth rates)
-Migration
Example of how migration can be a cause of an aging population
-When Poland joined the European Union in 2004, the total number of Polish emigrants living overseas rose quickly from 2 million to 3 million.
-Out-migration of the young has accelerated the rate at which Poland’s population is aging; loss of the young means that those who are not make up a larger proportion of a shrunken population.
What are some of the concerns for governments of countries with an aging population?
-Meeting the cost of economic care
-Emotional burden on younger and middle-aged people
Explain how one of the challenges of an ageing population can be meeting the economic cost of care for the elderly
-The elderly often no longer generate much wealth themselves
-Potentially enormous amounts of money must be made available for the elderly’s day-to-day living expenses, health treatments and housing costs.
Example of how one of the challenges of an ageing population can be meeting the economic cost of care for the elderly
Japan’s healthcare and nursing home costs by 2025 are expected to be almost US$1 trillion.
Explain how one of the challenges of an ageing population can be the emotional burden on younger and middle-aged people
Rising longevity is placing an emotional burden on younger and middle-aged people who must increasingly act as (unpaid) carers for older relatives who have developed Alzheimer’s disease or another form of dementia.
How have the causes of death changed thanks to improvements in healthcare?
-Fewer people now die in their 60s and 70s from cancer, heart diseases or strokes.
-Instead, more people now survive into their 80s and 90s, ages at which vulnerability to degenerative brain diseases and disorders becomes greatly increased.
What is the downside of the fact that more people now develop degenerative brain diseases?
-Many young people are totally unprepared for the role reversal that will occur in later life when, instead of being cared for by their parents, the situation is reversed.
-Moving relatives to a care home may help make life more manageable, but the effects of Alzheimer’s are still upsetting to witness in a loved one.
Explain ageing population challenges at the local scale
-The issues are amplified further at the local scale sometimes.
-In countries where homes and services for the elderly are funded by local taxes levied on working people, districts with an unusually high proportion of elderly face the most severe financial challenges.
Example of ageing population challenges at the local scale
In the UK, for instance, many coastal settlements have high proportions of older people living there as a result of age-selective migration.
Benefits of an ageing population
-Continued employment into old age
-Jobs as actors
-Jobs as politicians
-Involvement in charity and caring for grandchildren
Benefits of an ageing population- continued employment into old age
-Many elderly people who have worked in skilled occupations such as banking, teaching or medicine continue to work into their 70s and sometimes 80s.
-They may serve as consultants, providing valuable advice to younger staff, perhaps on a part-time basis.
Benefits of an ageing population- jobs as actors
Older actors are always needed to play film parts – for example, Dumbledore (played by Michael Gambon) and other older Hogwarts teaching staff in the Harry Potter films.
Benefits of an ageing population- jobs as politicians
In politics, the billionaire Donald Trump was elected as US President at the age of 70.
Benefits of an ageing population- involvement in charity and caring for grandchildren
-Elderly people often make a range of contributions to society by assisting with the running of charities and good causes.
-Some assist their own families by providing free childcare for grandchildren, thereby allowing both parents to participate in the workforce.
