Q

Example of a place with high level of technology

elab + evid

A

Elab: ppl can live in desert if water can be channelled from a river to their living environment.

Evid: Las Vegas in the U.S.A, is a city located within a deserted region. Advances in tech have enabled water to be transported to various places through pipes and canals.

Q

How to describe a population pyramid?

[Tip: follow the SLAB thing :) ]

    - Working population
    - Elderly/ Elderly dependent
  3. Describe the base
    - Narrow, which indicates a low BR (rectangular & bee hive)
    - Broad, which indicates a high BR (Triangular)
  4. Describe the tip/ apex
    - Narrow, indicates a low life expectancy rate (triangular)
    - Broad, indicated a high life expectancy rate (rectangular, bee hive)

Q

Better medical and health care

[Define medical and health care, how it affects infant mortality rate + link]

A

Medical care:
- Refers to the ~avaliability~ of hospitals, clinics, doctors and medical knowledge
Health care:
- Refers to ~immunisation~. Nutritional knowledge, the availability of community hospitals and other measures

Babies

  • Enabled many babies to survive beyond their first year
  • Thus, the infant mortality rate decreased when fewer babies below the age of one die, for every 1000 live births per year

Link: This is aimed at improving the quality of life

17
Q

Examples to show that having better medical and health care would lead to a lower death rate

(Hint: Infant morality rate + life expectancy)

A

India

  • Infant mortality rate decreased from 66 to 35 per 1000 live births
  • Life expectancy increased from 63 yrs to 68 yrs from 2000 to 2015
18
Q

Better hygiene

[elab (cause & effect) + evid]

A

Elab
Cause:
- Living conditions are clean and hygienic
Effect:
- In many countries, the DR has greatly decreased when there was a supply of clean water, and when the environment is clear of disease-carrying pests
- Ppl are less prone to falling sick and contracting diseases

Evid
- The life expectancy in Bangladesh increased from 65 yrs to 70 yrs from 2000 to 2010

19
Q

4 factors that lead to a high birth rate

A
  1. Lack of family planning
  2. Early marriages
  3. Preference for sons
  4. Need for farm labour
20
Q

Lack of family planning

[ elab + evid + link]

A

Elab:

  • Family planning refers to how many children a couple plans to have.
  • In many LDCs, ppl are less educated and know little about family planning methods.

Evid: Bangladesh

  • Ppl like Taslima, who are sent by family planning agencies, were to educate the ppl on family planning and give them free contraceptives
  • 1972, average of 7 babies per women
  • 2012, average 2.2 babies per women

Link:
- By raising awareness about the need to control family size, the number of babies per women decreased
OR
- This shows that the lack of family planning would lead to a high birth rate

21
Q

Preference for sons

[elab + evid + link]

A

Elab:

  • Some rural parts of China or India place a lot of importance on having sons.
  • They see sons capable of carrying on the family name or surname when they marry while daughters are not.
  • Couples may end up having many children because of deep-rooted traditional beliefs and values, or religious beliefs

Evid:
- For example, in India, some Hindu ceremonies require sons to perform religious rituals for parents.

Link:
- Thus, couples may continue to have children till they succeed to get a son.

22
Q

Early marriages

[ elab + evid + link]

A

Elab:

  • Couples who marry at an early age tend to have larger families than those who marry at a later age.
  • This is because the number of childbearing years for a woman who marries earlier is higher.

Evid:
- Sharavasti, India

Link:
- Hence, in countries where people marry young, such as those parts of India, the birth rates tend to be high

23
Q

Need for farm labour

[ elab + evid]

A

Elab:

  • Ppl in many LDC depend on farming to earn a living
  • farm work requires much labour and large families are thus preferred as there will be more hands to work on the land

Evid:

  • Liberia is one of the most reliant countries in agriculture in the world.
  • Almost 77% of it’s Gross Domestic Product (GDP) is agriculture
24
Q

5 consequences of a high rate of population growth

A
  1. High demand for resources
  2. Higher demand for housing
  3. Higher demand for education
  4. Higher demand for jobs
  5. Environmental problems
25
Q

Higher demand for resources

[ elab + evid + link]

A

Elab:

  • With more ppl, the demand for resources such as food and water also increases
  • Many LDCs suffer from shortage of food because not enough food is being produced to feed the rapidly growing population

Evid:
- 34% of India’s population is undernourished

Link: (address the question)
- Thus many ppl suffer from malnutrition and starvation

26
Q

Higher demand for housing

[ elab + evid]

A

Elab:

  • Rapid increase in population would result in competition for housing
  • This is especially so in cities of LDCs which have insufficient housing for its growing population
  • Ppl result to living in slums and squatter settlements

Evid:

  • Manila, Smoky mountain
  • Community living on dumping site
  • This is due to the lack of housing available for the large population in the city
27
Q

Higher demand for education/ lack of educational opportunities

[ elab + evid + link]

A

Elab:

  • with more babies born every year, there is a need to ensure that there are sufficient schools and teachers to educate the young
  • LDCs may lack the funds to build more schools

Evid:

  • Mexico City
  • a lot of children like Juan who are not able to attend school
  • This is because of the lack fo support and help from the government

Link:
- As a result, not everyone will be able to attend school and obtain a good education

28
Q

2 actions taken to control a high rate of population growth

A
  1. Education on family planning

2. Incentives and penalties

29
Q

How does education on family planning control high population growth?

A
  • Taught various methods to control family size
    e. g. In Bangladesh, women from family planning agencies have been sent to rural areas to educate ppl and give advice on family planning
30
Q

How does incentives control a high rate of population growth

[ elab + evid]

A

Elab:
- Rewards in the form on monetary incentives may be given to couples who have fewer children

Evid:

  • When the SG anti-natalist policy was implemented
  • Births per 1000 ppl in 1960-1980 went from 39 to 17
31
Q

How does penalties control a high rate of population growth

[ elab + evid]

A

Elab:
- Those couples with more children would be penalised, for example by having to pay higher taxes

Evid:
- China’s ‘one child policy’ was implemented in 1979
in response to its rapid population growth
- More than one child had to pay heavy fines to the government
