Demographics Flashcards
How are family and the population linked?
- New members of the population are usually raised by their family, and the level of care they receive determines their chances of survival.
What factors affect population size? (4 examples)
- Births - how many babies are born
- Deaths - how many people die
- Immigration - how many people leave the country to live elsewhere.
- Emigration - how many people enter the country from elsewhere.
What is the definition for birth rate?
- Number of live births per thousand of the population per year.
What are the patterns and trends in birth rates?
Give at least 4 examples
- Long term decline in the number of births since 1900.
- 1900 - England and Wales - birth rate of 28.7 - 2014 - fallen to around 12.2.
- Fluctuations in the number of births - three ‘baby booms’ in the 20th century:
1) First baby boom came after the two world wars as returning service men and their partners started families.
2) Third baby boom - 1960s - birth rate fell sharply during the 1970s.
- Birth rate rose during the 1980s
- Fell again after the early 1990s with some increase since 2001.
What are the factors which determine birth rate?
- Number of women who are of childbearing age
- How fertile women are
What is the total fertility rate?
- Average number of children women have during their years of fertility.
What are the patterns and trends in the total fertility rate for the UK?
Give at least 4 examples.
At least 4 examples from:
- Risen in recent years but much lower than the past
- 2001 - women had an average of 1.63 children
- 2014 - women had an average of 1.83 children
- 1964 - during the 1960s baby boom - women had an average of 2.95.
What do changes in birth and fertility rates reflect?
- More women are remaining childless
- Women are postponing having children - the average age is now 30 years.
- Fertility rates for women in their 30s and 40s are on the increase.
- Older women may be less fertile and fewer fertile years remaining - they produce less children
What are the reasons for the decline in birth rates?
- Changes in the position of women
- Decline in the infant mortality rate
- Children becoming an economic liability
- Child centeredness
How might changes in the position of women impact on the decline in birth rates? (Give at least 2 reasons)
- Women have more legal equality with men - the right to vote.
- Increased educational opportunities - women now do better than men in school.
- More women are in paid employment
- Laws to protect women against unequal pay
- Changes in attitudes towards the role of women in the family
- Women now have easier access to divorce
- More access to abortion and contraception - gives women more control over their fertility.
How might the decline in infant mortality rates impact on the decline in birth rates?
- Couples are wanting to have less children - likely-hood of their existing children dying as infant is less.
- Parents want to invest more time for their existing children so don’t want as many.
How might children becoming an economic liability impact on the decline in birth rates?
- Until late 19th Century - children were economic assets because they could earn and income.
- Since late 19th Century - children have become economic liabilities because of laws such banning child labour, compulsory education and higher school leaving age etc.
- Being an economic liability for longer - costs of raising children has risen - people may therefore choose to have fewer children.
How might child centeredness impact on the decline in birth rates?
- Parents are having fewer children but wanting to spend more time with the ones they do have.
What does the infant mortality rate measure?
The number of infants who die before their first birthday, per thousand of alive babies born each year.
What was the infant mortality rate for the UK in 1900?
154 - meaning over 15% of babies died within their first year of life.
What were the reasons for the fall in the infant mortality rate for the UK, in the 1st half of the 20th Century?
Give at least three examples
- Improved housing and better sanitation - reduced amount of infectious diseases
- Better nutrition for mother and child - children were healthier and more likely to survive
- Better knowledge of hygiene, child health and welfare - often spread via women’s magazines.
- A fall in the number of women working - may have improved both the health of the mother and baby.
- Improved services for mothers and children - antenatal and postnatal classes
What medical changes impacted on the decrease of the infant mortality rate from the 1950s onwards?
- Mass immunisations against childhood diseases such as whooping cough and measles.
- Use of antibiotics - fight infection
- Improved midwifery and ultrasound techniques
What was the result of medical changes on the infant mortality rate?
- UK IMR had fallen to 30 - and by 2012 had fallen to 4.
What are the future trends in UK birth rates?
- Immigration has caused:
1) Families to be smaller
2) Birth and fertility rates to decrease
What are the effects of changes in fertility?
1) Smaller families
2) The dependency ratio
3) Public services and policies
How has the effects of changes in fertility resulted in smaller families?
- Women are more likely to be free to work and create a dual earner family.
- More wealthy couples may be able to afford the costs of childcare - needed to allow parents to work full time and still have a large family.
What is the dependency ratio?
- Relationship between the size of the working/productive part of the population, and the non-working/dependent part of the population.
How does changes in fertility impact on the dependency ratio?
- Fall in the number of dependent children reduces the ‘burden of dependency’ on the working population.
- Long term - fewer babies being born means a smaller working population - dependency ratio could increase again.
- Childhood may become a lonelier experience - fewer children have siblings.
- Non working old are economically dependent - fewer babies means the working population able to provide for the old will be smaller.
How would a fall in birth rates impact on public services and policies?
- Fewer schools, maternity and child health services may be needed.
- Impact on the cost of maternity and paternity leave.
- Impact on types of houses that need to be built.
- The government could decide to reduce school class sizes, instead of reducing the number of schools.
What is the definition for death rate?
Number of deaths per thousand of the population per year
What are the patterns and trends in death rates?
Give at least two examples
At least two from:
- 1900 - death rate at 19 but by 2012 - 8.9 (more than halved)
- Begun to fall about 1970 - continued until 1930.
- Rose slightly in 1930s and 40s
- Declined slightly since 1950s
What are the reasons for the decline in death rate?
1) Changes in health
2) Improved nutrition
3) Medical improvements
4) Smoking and diet
5) Public health measures
6) Other social changes
How have changes in health impacted on the decline in death rate?
- By the 1950s, diseases affluence replaced infectious diseases.
- Cancer usually affects old/middle aged people.
What are some examples of ‘diseases of affluence’?
Give two examples
- Heart disease
- Cancer
What is one possible reason for the decline in death rate due to ill health?
At least one from:
- Natural resistance to diseases
- The diseases have become less powerful
How have medical improvements impacted on the decline in death rate?
- Before 1950s - medical improvements played no part in the reduction of deaths caused by infectious diseases.
- After the 1950s - improved medical knowledge and techniques helped reduce death rate.
- Recently - improved medication, by-pass surgery/other developments - reduced number of deaths caused by heart disease by 1/3.
Give at least three examples of medical improvements that have impacted on the decline in death rate
At least three from:
1) Introduction of antibiotics
2) Immunisation
3) Blood transfusion
4) Improved maternity services
5) Introduction of NHS - 1948
How have public health measures impacted on the decline in death rate?
Give at least two examples of the laws passed.
An improved government (20th Century) had the power to pass new laws, including (at least two of following):
1) Housing - drier, better ventilated and less overcrowded
2) Purer drinking water
3) Combat adulteration of food
4) Milk pasteurisation
5) Improved sewage disposal methods
What are examples of other social changes that impacted on the decline in death rate?
Give at least three examples
At least three from:
1) Decline in dangerous occupations, such as mining
2) Smaller families - reduced infection transmission rate
3) Greater public knowledges of the causes of illness
4) Lifestyle changes inc. the reduction in the amount of men who smoke.
5) Higher incomes to allow healthier lifestyles
What is the definition for life expectancy?
- How long, on average, a person born in a given year can expect to live.
