demography Flashcards
birth rate
the number of live births per 1000 of the population per year
give the 2 main factors that determine birth rates
- number of women who are of a childbearing age (usually 15-44 yrs), average age to give birth is now 30
- how fertile they are (how many children they have)
total fertility rate (TFR)
the average number of children women will have during these fertile years (2.95 children in 1964 -> 1.83 in 2014)
briefly explain the 6 changes in women’s position during the 20th century as a cause for the decline in birth rate
- legal quality with men (against sex discimination & right to vote)
- increased educational opportunities
- more women in paid employment
- changes in attitudes to family life and womens role
- easier access to divorce (divorce reform act 1969)
- access to abortion and reliable contraception
briefly explain which reason Harper (2012) thinks is the most impactful on birth rate and total fertility rate
education of women.
Because women now see other possibilities other than their traditional expressive role so many women now are choosing to delay childbearing or remain childless rto pursue a career.
infant mortality rate (IMR)
the nummber of infants who die before their 1st birthday, per 1000 babies born alive per year
briefly explain Harper (2012) ideas linking the correlation between the IMR and birth rate
argues that a fall in the IMR leads to a fall in birth rate as if parents lose their infant then they have more children to replace which increases birth rate, whereas if infant survive they have fewer children.
briefly explain the 4 changes in the UK that made the UK’s IMR decrease during the 1st half of 20th century and the 2 changes in the second half of the 20th century, as a cause for the decline in birth rate
1st 1/2 of 20th century:
- improved housing and better sanitation
- better nutrition of mum and baby
- better knowledge of hygiene, child health and welfare
- improved services for mothe and baby (e.g. antenatal clinics)
2nd 1/2 of 20th century:
medical factors:
- mass immunissation against childhood diseases
- use of antibiotics to fight infection
briefly explain the 2 changes that have made children economically liable on parents during the 20th century as a cause for the decline in birth rate
- laws banning child labour & compulsory schopol, making them dependent on parents for longer
- changing norms of what children have a right to expect from their parents in material terms = cost of raising a child has increased
briefly explain how child centredness during the 20th century is a cause of the decline in birth rate
increasing child centredness in the family and society on a whole has encouraged shift from quantity to quality = parents now have fewer children and spend more attention and resources on these few
dependency ratio
the relationship between the size of the working population vs size of non-working (dependent) population.
the earnings of working population must support dependent population
briefly explain the** effects** of changes in the birth rate and TFR on many aspects in society: family, dependency ration, vanishing children, public services and policies, an ageing population
family
- smaller families = women free to work = dual earner couples
- better off couples may still have larger families as can afford childcare = borth work full time
dependency ratio
- children make up large part of the dependent population, so fall in number of children reduces burden of dependency on working population
- long term: fewer children = smaller working population in future = increase in burden of dependency
vanishing children
- decrease in fertility rate = increase in loneliness of children with no siblings and fewer voices to promote interests of children when adults remain childless
public services and policies
- lower birth rate = fewer schools and maternity/paternity leave pay and child health services needed
- government more likely to reduce class sizes than the number of schools
an ageing population
- lower birth rate = changes to average age of population, more old than younger people
death rate
the number of deaths per 1000 of the population per year
briefly explain Tranter (1996) ideas of why there has been a decline in the death rate in middle of 19th to the middle of 20th century
a result of the decline in the number of deaths from infectious disease (e.g. measles and TB)
From 1950’s he said there was diseases of affluence (wealth) such as heart disease and cancer (caused by inactivity and smoking) that replaced infectious diseases as main cause of death.
briefly explain the 5 reasons for the decline in death rate
- improved nutrition: McKeown argues it reduced deaths from TB and it helped increase resistance to infection and survival of those who became infected. However ignores why females live longer than males, even though they recieve smaller share of family food supply.
- medical improvements: since 1950’s it has caused advances in antibitoics, mass immunisation, blood transfusion, set up NHS in 1948
- smoking and diet: Harper argues that in 21st century, obesity has replaced smoking as the new lifestyle epidemic. Harper concluded that we’re moving towards an American health culture where lifestyles are unhealthy and long lifespan is achieved by costly medication.
- public health measures: In 20th century governments passed laws that improved public health and environment quality. E.g. Clean Air Act 1963, NHS health campaigns, milk tokens for kids.
- other social changes: decline of dangerous manual ocupations, smaller families reduces transmission of infection, greater public knowledge of causes of illness, lifestyle changes, higher incomes to afford private healthcare and gym memberships
life expectancy
how long on average a person born in a given year can expect to live.
give 2 stats from 1900 and 2024 showing as death rates decrease, life expectancy increases
Men born in 1900 had a life expectancy of 50 whereas women had 57yrs.
Men born in 2024 have a life expectancy of 82 and women have 92.6yrs.
give 4 reasons why women generally live longer than men, although the gap has narrowd due to changes in employment and lifestyle
- men are biologically more likely to develop cardiovascular problems due to fat lying around organs
- mental health and suicide: men have a suicide rate of 15.3 per 100,000 people a year and women have 4.9 per 100,000.
- men are more likely to avoid doctors and ignore any health concerns
- men are more likely to carry out risky behaviours
