Topic 2 - Demography Flashcards
What is demography?
The study of populations and their characteristsics.
What are the characteristsics of demogrpahy?
- Size
- Age structure
- Births
- Deaths
- Immigration
- Emigration
Births
- The number of lives per thousand of the population per year.
- Long term decline in number of births since 1900.
- Approx 29 in 1900, 12 in 2014.
- Baby booms
Patterns of baby booms.
- A baby boom is a period marked by a significant increase of birth rate.
- The first 2 came after the world wars (1914-18 and 1939-45) as returning service men and their partners started families that they had postponed during the war.
The total fertility rate (TFR).
- Average number of children women will have during their fertile years.
- The factors determining the birth rate are the proportion of women who are of childbearing age (15-44) and how fertile they are.
- UK’s TFR has steadily decreased since the 60’s
- More women are remaining childless
- Women are postpoining having children: average age of giving birth is approx. 31 and fertility rates for women in their 30’s and 40’s are increasing.
Patterns of TFR.
- On average it has decreased since its all time peak in 1964 (aprox. 3) and had a steep decline in 1977 (approx. 1.7).
- Lowest rate was recorded in 2020 (approx. 1.6) due to the start of the coronavirus pandemic.
Reasons for the decline in birth rate.
Include social, economic, cultural, legal, political and technological factors.
1 - Changes in women’s position.
Harper (2012)
- Legal rights
- Education (women do better than men in school)
- More women in paid employement with equal rights
- Easier access to divorce
- Birth control and abortion
- Changes in attitudes
Harper - education is the most important reason for the long term fall in birth rates and fertitlity rates
- There has been a change in mindset - leading to fewer children
- Educated women are more likely to use family planning and see other possibilities.
2 - Decline in infant mortality rates.
Brass and Kabir (1978)
- IMR is the number of children who die before their first birthday, per thousand babies born alive, per year.
Harper - fall in IMR leads to fall in birth rate. - In 1900, IMR in the UK was 154
- In 2018, IMR in the UK was 4
- Improved housing, better nutrition, better healthcare, better knowledge of hygiene,fall in number of married women working, improved services: antenatal and postnatal, mass immunisation, use of antibiotics and improved midwifery contributed to the fall in IMR in the 20th century.
- Brass and Kabir - the trend to smaller families began not in, rural areas where IMR originally began to fall, but in urban areas, where the IMR remained higher for longer.
3 - Children are now an economic liability.
- Until the 19th century children were an economic asset
- Laws - banning children labour, compulsory schooling and raising shcool leaving age - children are dependent on parents for longer.
- Changing norms - what do children have the right to expect?
- Parents therefore feel less able or willig to have a large family.
Child centredness.
Childhood is now socially constructed as a uniquely importnant period in the individuals life. Encouraged a shift from quantity to quality.
Future trends in birth rates.
- Overall birth rates, fertility rates and family sizes have falllen in the last century.
- There was a slight increase in births after 2001 but sicne 2012 there has been a slow decrease.
- Immigration could be a reason for this - these mothers tend to have a higher fertility rate.
Effects of changes in fertility.
- The family
- The dependency ratio
- Public services and policies
1 - The family.
Smaller families mean women are more likely to be free to go to work, creating the dual earner couple, BUT, family size is only one factor - for example better off couples may be able to have large families and still afford childcare which allows both of them to work
2 - The dependency ratio.
- The relationship between working and non-working parts of the population.
- Less children = ‘reduces the burden of dependency’ BUT in the long term there will be a smaller working population and the burden of dependency may begin to increase again.
Vanishing children
- Childhood may become lonelier, more childless adults might mean less voices speaking up for them OR childhoood could become more valued.
3 - Public services and policies.
- Fewer schools, child health and maternity services needed.
- Affects to maternity and paternity leave and the type of home built BUT many of these are political decisions, for example instead of reducing the number of schools, the government could decide to have smaller classes.
- Ageing population - because women are having fewer babies the average age of population is rising. This will have an effect on the types of services needed.
Deaths.
- The number of deaths per thousand of the population per year.
- In 1900, the death rate was 19
- In 2012, it had more than halved to about 9
- The death rate had begun falling from 1870 and continued to do so until 1930
- Rose slightly during 30/40’s - the period of the great depression followed by WWII but since 50’s it has declined slightly.
Reasons for the decline in death rate.
Tranter (1966)
- Tranter found that over 3/4 of the decline in death rate from 1850 to 1970 was due to a fall in the number of deaths from infectious diseases such as measles, small pox, and tuberculosis (TB)
- Deaths from diseases were most common for the younger generation and msot of the decline of death rates occured among infants, children and young adults.
- By the 50’s, ‘diseases of affluence’ (wealth) such as heart disease and cancers had replaced infectious diseases as the main cause of death.
- These degenerative diseases affect the middle age and older generations more than the young.
How/why does wealth impact health…
1 - Improved nutrition.
Mckeown (1972)
- Mckeown argues that improved nutrition accounted for up to half the reduction in death rates and was particularly important in reducing the number of deaths from TB. Better nutrition increases resistance to infections and increased survival chances of thsoe who become infected.
- However, he doesnt explain why females who receive a smaller share of the family food supply lived longer than males.
- He also fails to explain why deaths for some infectious diseases actually rose at a time of improving nutrition.
2 - Medical improvements.
- After the 50’s, improved medical knowledge, tecnniques and organisation did help to reduce death rates
…Introduction of antibiotics
…Immunisation
…Blood transfusion
…Improved maternity services
…NHS (1948) - More recently, improved medication, bypass surgery, and other developments have reduced deaths from heart disease by 1/3.
