Topic 4: Demography. Flashcards
What is net migration?
The difference between the number of immigrants entering a country and the number of emigrants leaving it.
What is birth rate?
The number of live births per thousand of the population per year.
- In 1900, England/Wales had a birth rate of 28.7, but by 2014, it had fallen to an estimated 12.2. In 2020, it has fallen to 11.4.
- Have been fluctuations in births with three baby booms in the 20th century:
1. After the two world wars (1914-1918, 1939-1945).
2. 1960s/1970s.
3. 1990s.
Reasons for the decline in the birth rate:
- Changes in women’s position.
- Decline in infant mortality rate.
- Children are now an economic liability.
- Child centredness.
Major changes to women’s position in the 20th century:
- 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 contraception, giving women more control over their fertility.
(birth rates) Changes in women’s position:
Harper (2012) argues education of women is most important reason for long-term fall in birth and fertility rates. It has led to a change in a mind-set among women, resulting in fewer children.
- Educated women more likely to use family planning.
- Other possibilities in life apart from traditional role of housewife and mother.
- Women pursue careers.
- Women delaying childbirth.
Changes in women’s position (AO2):
- In 2012, 1 in 5 women aged 45 was childless double the number of 25 years earlier.
- Although, fertility rates decreased in all age groups, for women aged 40 years and over it increased.
- Harper also notes that, 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 come to be seen as deviant or less acceptable.
Voluntary childlessness.
- Women’s control over their own fertility has seen an increasing number of women voluntarily choosing to reject childbearing altogether.
- Hakim (2010) argues this is a relatively new lifestyle choice which was only brought about by the contraception revolution.
- However, attitudes in favour of procreation are still quite powerful - the social disapproval from family and wider community can be a strong influence. Women’s fertility status is still very much considered public property.
Voluntary childlessness. Gillespie (2003) identifies two factors for voluntary childlessness:
- Pull factor - they are attracted by the pull of being child free, especially the increased freedom and better relationships with partners that it affords. Married couples without children have more disposable income.
- Push factors - they may experience a push away from motherhood. Park (2005) found that women who tended to see parenting as conflicting with their leisure or career interests. These women were disinterested in children.
What is the total fertility rate?
The average number of children women will have during the fertile years.
- Factors that determine the TFR are:
1. Proportion of women who are of childbearing age.
2. How fertile they are e.g. how many children they have.
- The UK’s TFR has risen in recent years, but still much lower than in the past: 1960s = 2.95 children per man, 2001 = 1.63 children per woman, 2019 = 1.65 children per woman.
Reasons why there has been an increase in the average age at which women give birth:
- Women are more likely to concentrate on careers.
- Women spend longer in full-time education.
- More widespread access to contraception.
- More socially acceptable to give birth later.
- More reproductive technology available to older women.
What is the infant morality rate?
Measures the number of infants who die before their first birthday, per thousand babies born alive per year.
- Harper argues a fall in the IMR leads to a fall in the birth rate.
During the first half of 20th century, the UK’s IMR began to fall. Was due to several reasons:
- Improved housing and better sanitation.
- Better nutrition, including that of mothers.
- Better knowledge of hygiene, child health and welfare, often spread via women’s magazines.
- A fall in the number of married women working may have improved their health and that of their babies.
- Improved services for mother and children, such as parenting class and baby clinics.
- Rise in mass immunisation and medicine both contributed to a continuing fall in the IMR.
Effects of changing in fertility: The Dependency Ratio.
- Dependency ratio = proportion of the population who are of working age compared with the proportion who are not working and therefore dependent others (children and the retired).
- However, in long-term, fewer babies being born will mean fewer young adults and a smaller working population thus increasing the dependency ratio.
- How might fewer babies being born impact the dependency ratio? Reduces the ‘burden of dependency’.
Effects of changes in fertility:
- The effect of fewer babies being born in family has led to smaller family sizes. Means women are freer to go out and work - dual earner couple.
- In contrast, high dual earner couples can afford to have large family and outsource childcare.
- Effect of fewer babies being born in the family has impacted public services and policies in several ways. For instance, fewer schools, maternity and child health services may be needed. Cost of maternity and paternity leave and housing is impacted. Lastly, rise in ageing population.
What are death rates?
The number of deaths per thousand of the population per year.
- In 1900, death rate stood at 19, whereas by 2012 it had more than halved; 8.9.
- Death rate already begun falling from 1870 and continued until 1930. Rose slightly during 1930s-1940s - the period of the great economic depression, followed by WW2, but since 1950s it has declined slightly.
- Tranter (1996) - 3/4 of decline rate from about 1850 to 1970 was due to fall in number of deaths from infectious diseases.
- By 1950s, ‘diseases of affluence’ (wealth) such as heart disease and cancers had replaced infectious diseases as the main cause of death.
Reasons for the decline in the death rate:
- Improved nutrition - Mckeown (1972) - better nutrition increased survival change, reduce death rates. However, doesn’t explain why women outlive men when they have smaller food supply and why some infectious diseases rose at time of improving nutrition.
- Medical improvements - Before 1950s, medical improvements played no role in reduction of deaths from infectious diseases. After 1950s it did. Advances included: antibiotics, blood transfusions and NHS (1948).
- Smoking and diet - Harper - decline in death rates due to less people smoking. But in 21st century, obesity has replaced smoking. Despite this, drug therapies have kept death rates low.
- Public health measures - 20thC saw rise of effective central and local gov with power to enforce and create laws and improved health and quality of environment: improvements in housing, purer drinking water, improved sewage disposal methods.
- Other social changes - help reduce death rate during 20thC: decline in dangerous manual occupation jobs, smaller families reducing transmission rate of infections, greater public knowledge, lifestyle change, higher income.
What is life expectancy?
Refers to how long on average a person born in a given year can expect to live.
- As death rates increase, life expectancy increases.
- Males born in England in 1900 had life expectancy of 50; 2013 they had life expectancy of 90.7.
- Harper predict we will soon achieve ‘radical longevity’ with many more centenarians (people over 100). Currently there are 10,000 in UK.
Life expectancy: class, gender and regional differences.
- Women live longer than men, but because of changes in employment and lifestyles this gap was narrowed e.g. smoking.
- Those living in North and Scotland have lower life expectancy than those in South.
- WC men in manual jobs are nearly 3x as likely to die before 65 compared to MC professional men.
- Walker (2011) - those living in poorest areas of England die on average 7 years earlier than those in richest areas.
What is the ageing population?
- There are fewer young people are more older people in the population. Number of people aged 65 or over equalised to number of under-15s in 2014.
- Average age of UK is rising: 1971 - 34.1 years, 2020 - 40.5 years, 2031 - predicted to be 42.6 years.
The ageing of the population is caused by 3 factors:
- Increasing life expectancy
- Declining infant mortality
- Declining fertility.
