Families and Households: Demography Flashcards
What is demography?
- The study of populations and their characteristics including: Population size, growth, and decline, and age structure.
In 1801 Britain had a population of
10.5 million.
By 1901 Britain had a population of
37 million, today it is 65 million.
Until the 1980s UK population growth was largely the product of
natural change - the result of there being more births than deaths. However since the 1980s, most of the growth has come from net migration.
Immigration
When people enter a country from elsewhere and integrate into its society. This leads to a population increase.
Emigration
How many people leave the country to live elsewhere (causing population decrease).
Birth rate
The number on live births per 1000 of the population per year.
What happened from 1900 until 2001?
There was a long-term decline in birth rates, but the birth rate has been increasing again.
When did birth rates peak?
2012 at 12.8, the highest since 1971.
Factors determining birth rate
The proportion of women who are of childbearing age (15-44).
How fertile they are - that is, how many children they have.
Total fertility rate (TFR)
The average number of children women will have during their fertile years. Despite this rising since 2001 to 1.94 in 2012 from an all time low of 1.63, it is still far lower than its peak of 2.95 children in 1964 (the 60s baby boom). In 2014 it was 1.83
Changes in fertility and birth rates reflect the fact that:
More UK born women are remaining childless than in the past.
Women are postponing having children - average age for giving birth now 30 and fertility rates for women in their 30s and 40s are now on the increase. Nevertheless, they have fewer fertile years remaining so produce fewer children.
Reasons for decline in birth rate 1900-2001:
Changes in the position of women
Major changes in the 20th century including:
-Legal equality with men, including right to vote.
Increased educational opportunities - girls now do better at school than boys.
-More women in paid employment, plus laws outlawing unequal pay and sex discrimination.
-Changes in attitudes to family life and women’s role.
Easier access to divorce.
-Access to abortion and reliable, giving women more control over their fertility.
Harper (2012)
Argues education of women is the most important reason for the long-term fall in birth and fertility rates. Argues it has led to a change in mindset for women, resulting in fewer children. Educated women are most likely to use family planning and see other possibilities in life apart from the traditional housewife and mother. Many choose to delay childbearing, or not have children at all, in order to pursue a career.
In 2012 one in five women aged
45 were childless, double the number 25 years earlier.
Harper (Patterns of fertility)
Says once a pattern of low fertility lasts for more than one generation, cultural norms about family size change. Smaller families become the norm and large ones are seen as “deviant” or less accepted.
Infant mortality rate (IMR)
The number of infants who die before their first birthday, per thousand babies born alive, per year.
Harper (fall in IMR)
Argues that a fall in the IMR leads to a fall in birth rate. Because, if many infants die, parents have more children to “replace” those they have lost, thereby increasing the birth rate. By contrast, if infants survive, parents will have fewer of them.
What was the IMR in 1900?
154, 15% of babies died within their first year.
Reasons for decline in birth rate 1900-2001:
Falling IMR
- Improved housing and better sanitation, such as flushing toilets and clean drinking water, reducing infectious disease.
- Better nutrition, including that of mothers.
- Better knowledge of hygiene, child health, and welfare, spread via women’s magazines.
- A fall in the number of married women working may have improved their help and that of babies.
- Improved services for mother and children, such as antenatal and postnatal clinics.
Reasons for falling IMR post 1950:
Medical factors
- Campaigns to improve public health measures.
- Mass immunisation agains childhood diseases e.g whooping cough and measles.
- The use of antibiotics to fight infection.
- Improved midwifery and obstetric techniques.
By 1950 the UK’s IMR had fallen
to 30, and by 2012 it stood at 4 - barely 1/40th of its 1900 figure.
Brass and kabir (1978)
Argue the trend to smaller families began in urban areas. This is interesting as the IMR first began to fall in rural areas, suggesting medical practices may not affect birth rates in the way we think they have.
Reasons for decline in birth rate 1900-2001:
Children as economic liabilities
- Until the late 19th century, children were an economic asset to their parents, they could be sent out to work.
- But, laws banning child labour, introducing compulsory schooling, and raising the school leaving age mean that children remain economically dependent on their parents for longer.
- Changing norms about what children have a right to expect from their parents in material terms mean that the cost of bringing up children has risen.
- As a result of financial pressures children are less willing or able to have large families.
Reasons for decline in birth rate 1900-2001:
Child Centeredness
- Increasing child centeredness of both the family and society as a whole means that childhood is now socially constructed as a uniquely important period in the individual’s life.
- Has encouraged a shift from ‘quantity’ to ‘quality’.
- Parents now have fewer children and lavish more attention and resources on these few.
Reason’s for minor increase in birth rate since 2001:
Increase in migration
- On average, mothers from outside the UK have a higher fertility rate than those born in the UK.
- Babies born to mothers from outside the UK accounted for 25% of all births in 2011.
- Projection for up to 2041 expects the annual number of births to be constant at around 800 000 a year.
Impact of fertility changes:
The family
- With fewer children, women are more likely to be able to go out to work, thus creating the dual earner couple typical of many professional families.
- Better off couples, however, may be able to have larger families and still afford childcare that allows them to both work full time.
- Falling fertility rates mean fewer children, so childhood may become a lonelier experience, as fewer children will have siblings.
- More childless adults may mean fewer voices speaking up in support of children’s interests.
- Fewer children could also mean children are more valued.
Impact of fertility changes:
The dependency ratio
-Children make up large part of the dependency population, so a fall in the number of children reduces ‘the burden of dependency’ on the working population.
The dependency ratio
The relationship between the size of the working or productive part of the population and the size of non-working or dependent part of the population. The earnings, savings, and taxes of the working population must support the dependent population.
Impact of fertility changes:
Public services and policies
- Fewer schools and maternity and child health services may be needed.
- Affects the cost of maternity/paternity leave and types of housing built.
- However these decisions are political, the government could decide to have smaller class sizes instead of reducing the number of schools.
Death rate
The number of deaths per thousand of the population per year.
What was the death rate in 1900?
19, whereas by 2012 it has dramatically fallen to 8.9.
In the UK the overall number of deaths has remained stable since 1900 at round
600 00 per year, but there have been some important fluctuations such as the two world wars, covid-19, and the flu epidemic of 1918. However, the death rate has fallen since 1950.
Reasons for the decline in the death rate during the 20th century:
Decline in deaths from infectious diseases
- By the 1950s, ‘diseases os affluence’ such as heart disease and cancers replaced infectious diseases as the main cause of death. Degenerative diseases affect the middle aged and old rather than the young.
- Possible that the population began to develop some natural resistance or some diseases became less powerful.
Tranter (1996)
Argued over 3/4 of the decline in death rate from 1850 to 1970 was due to a fall in deaths from infectious diseases.
Reasons for the decline in the death rate during the 20th century:
Improved Nutrition
Better nutrition increased resistance to infection and increased the survival chances of those who did become infected.
(McKeown)
McKeown (1972)
Argues improved nutrition accounted for up to half the reduction in death rates and was particularly important in reducing the number of deaths from tuberculosis.
However McKeown does not explain why females, who receive a smaller share of family food, lived for longer than measles.
Reasons for the decline in the death rate during the 20th century:
Medical Improvements
Post-1950, improved medical knowledge, techniques, and organisation helped to reduce death rates. Advances included introduction of antibiotics, immunisation, blood transfusions, improved maternity services. Also the NHS was set up in 1948.
Most recently, improved medication, by-pass surgery, and other developments have reduced deaths from heart disease by one-third.
When was the NHS set up?
1948
Reasons for the decline in the death rate during the 20th century:
Smoking and Diet
The fall in death rates in recent decades has come from a reduction in the number of people smoking.
21st century obesity has replaced smoking as the new lifestyle epidemic; in 2012 one quarter of all UK adults were obese. Although obesity has dramatically increased, deaths have been kept low because of drug therapies.
Harper (smoking)
Believes that the great fall in death rates in recent decades has come not from medical improvements, but simply from a reduction in the number of people smoking.
Harper (obesity)
Harper suggests that the UK may be moving to an ‘American’ health culture where lifestyles are unhealthy but where a long lifespan is achieved by use of costly medication.
Reasons for the decline in the death rate during the 20th century:
Public Health Measures and Environmental improvements
In the 20th Century, more effective central and local governments passed laws that led to a range of improvements in public health and the quality of the environment.
These included improvements in housing (producing drier, ventilated, less overcrowded accommodation), purer drinking water, laws to combat the adulteration of food and drink, pasteurisation of milk and improved sewage disposal methods.
The Clean Air Acts 1952
Reduced air pollution, such as the smog that led to 4000 deaths, in five days.
Reasons for the decline in the death rate during the 20th century:
Other Social Changes
- The decline of dangerous manual occupations such as mining.
- Smaller families reduced the rate of transmission of infection.
- Greater public knowledge of the causes of illness.
- Lifestyle changes, especially the reduction in number of men who smoke.
- Higher incomes, allowing for a healthier lifestyle.
Life expectancy
Refers to how long a person born in a specific year can be expected to live.
Males born in England in 1900 could expect on average to live until they were 50 and females until 57
whereas males born in 2013 can expect to live for 90.7 years and females for 94 years.
A new-born baby today has a better chance of reaching its 65th birthday than a baby
born in 1900 has of reaching its 1st birthday.
Harper (2012)
Predicts if the trend to greater longevity continues, we will achieve ‘radical longevity’, with many more centenarians.
How many centenarians are there currently in the UK?
10,000, and by 2100 there are projected to be one million.
What are the gender differences in life expectancy?
Women generally live longer than men, although the gap has narrowed due to changes in employment and lifestyle (such as more women smoking).
What are regional differences in life expectancy?
Those living in the North and Scotland have a lower life expectancy than those living in the South.
What are the class differences in life expectancy?
Working class men in unskilled or routine jobs are nearly three times as likely to die before they are 65, compared with men in managerial or professional jobs.
Walker (2011)
Those living in the poorest areas of England die on average seven years earlier than those in the richest areas.
The difference in life expectancy for people who are disability free is 17 years longer.
The average age of the UK population is rising. In 1911 it was 25, in 2013 it was
40.3, and by 2037 it is projected to reach 42.8.
The ageing population is the result of the following 3 factors:
- Increasing life expectancy: people living longer into old age.
- Declining infant mortality: very few infants die early in life.
- Declining fertility: fewer young people are born in comparison to the number of older people in the population.
For first time in 2014
The number of people aged 65+ equalled the number of under 15s.
How much of the population was over 65 in 2011?
9.2 million people, making up 16.4% of the total population of England and Wales, that is 1 in 6 of the population.
On current projections by 2041 there will be
as many 78-year olds as 5-year olds.
Effects of an Ageing population:
Public Services
Older people consume a larger proportion of services such as health and social care than other age groups.
Particularly true of the ‘old old’ (75+).
However, caution should be made regarding over generalisation - many old people remain in relatively good health well into old age.
An ageing population may also mean there are changes to policies and provision of housing, transport, and other services
