Q

Why is the world’s population not evenly spread out around the globe?

A

Because of different human and physical factors

eg- land. If the land is flat, it is easy to build on so will be more populated, for example in Bangladesh

Also, fertile soil attracts more people as people can grow crops to earn a living. For example in Holland

Places with lots of raw materials like coal are likely to be more densely populated

also, better climates (not too hot or cold) will be more populated too

Q

Why does a large percentage of the population live in urban areas?

A

there tend to be better job opportunities, which encourage people to move there, particularly in high income cities such as New York.

Climate in urban areas tends to be ideal for growing crops, which encourages people to move there as they can earn a living by farming

There are also better communications, such as train systems and road networks, which makes it easier for people to move around

Q

CASE STUDY- Rural-urban migration in an LEDC

A

South Africa

many people migrate from less populated provinces in South Africa (eg Limpopo) to more urban provinces (eg Western Cape- Cape Town)

Push factors- Few rural houses have connection to electricity, lack of money- most people do not even own an electric cooker. Poor job opportunities-rely on tourism and farming for an income, Development of farm mechanisation caused heigh levels of unemployment. Relatively low quality of life (60% IN LIMPOPO LIVE BELOW THE POVERTY LINE), most households in Limpopo earn less the 1,000 rand a month

Pull factors- Jobs and better opportunities, better healthcare, schools, AVERAGE HOUSE HOLD INCOME IN SOUTH EARNS ABOUT 7,000 RAND a month

Q

What are some advantages of circular migration?

A

Reduces the demand on village food supplies

Migrants send money back home- can be used to improve farms

Q

What are some disadvantages of circular migration?

A

Losing work force- brain drain

Q

CASE STUDY- counter urbanisation

A

St Ives, Cambridgeshire,UK

25% of the population in St Ives commute to London everyday

Push factors- Urban areas seen as a place of noise, crime and pollution, Urban areas are expensive to live in, lack of open space

Pull factors- Rural areas seen as quiet, peaceful with a sense of community, Thought to have better schools and to be a safer place for children

Q

Describe the growth in global population

A

increased slowly until the 1800s.

Since then, world population has increased rapidly

In 2000, the worlds population was estimated to be around 6 million- double that of 1960

17
Q

Birth rate

A

The number of live births per 1000 people per year

18
Q

Death rate

A

The number of deaths per 1000 people per year

19
Q

Natural increase

A

The difference between the birth and death rate

20
Q

Describe why birth rate is higher in most LEDCs

A
  • religions against contraception
  • Children provide labour
  • Lack of knowledge of contraception
  • Women lack education and are expected to raise a family
  • High infant mortality rate encourages larger families
21
Q

Describe why birth rate is lower in MEDCs

A
  • Women go into professional careers, marry later and delay starting a family
  • High cost of living means it’s expensive to raise children
  • Contraception and birth control are easily available
22
Q

Describe why death rates are low in MEDCs and are falling in LEDCs

A
  • Better healthcare/sanitation
  • Developing cures for diseases- eg malaria
  • Education on health/hygiene
  • Higher income= more food
23
Q

Describe why death rates are increasing in some MEDCs and LEDCs

A
  • HIV is having an increasingly significant impact on death rates in LEDCs
  • in MEDCs, there is an increasing number of elderly people
24
Q

Describe the stages in the demographic transition model (DMT)

A

1) Population fluctuates but stays relatively stable (no set country)
2) Very rapid population increase (South Africa)
3) Population increases but less rapidly (India)
4) Very slow increase (UK)
5) Population slowly decreases (Germany)

25
What are some limitations of the demographic transition model? (DMT)
It is a generalisation Not all countries follow the same pathway Countries that do follow the DMT do so at different speeds
26
The stages of the DMT produce different sized....
population pyramids
27
What are the 3 age groups that a population pyramid is dived into?
- Young dependents 0-14 - Working population 15-64 - Old dependents 65+
28
CASE STUDY- population structure, Sub Saharan Africa
Malawi - wide base- many young dependents and a heigh birth rate - narrow top- few elderly dependents - malaria is an issue (malaria kills 1.2 million people a year) (60% of children under 3 catch malaria in Malawi) - AIDS is another problem (Occupies over half of hospital beds) (Affects 1 in 4 children) (Causes a decline in agricultural workforce- famine) benefits of structure- large work force for future Drawbacks of structure- Pressure on education, lack of housing (big families), strain on food supply
29
CASE STUDY- Population structure in South Asia
INDIA - A decreasing, though still high birth rate (due to anti natal policy) - Lower life expectancy ANTI NATAL POLICY - encourages smaller families through social change - Improved education standers and gender equality - Educating people about the benefits of having smaller families - New schools, roads and drinking water for areas that reached their targets
30
CASE STUDY- Population structure, Western Europe
France - Low birth rate and few young dependents - Low death rate and long life expectancy - Large working population Benefits of structure- Adds experience to workforce Drawbacks of structure- Pressure on healthcare, strain on pension fund, pressure on care homes Pro natal policy- France has an ageing population and is trying to tackle it with a pro natal policy to provide o more favourable age structure and dependency ratio - 3 years paid parental leave for father or mother - Day car for babies under 3 is paid for by the government - The more children a woman has, the earlier she can retire on a full pension - It has had some success but has not been entirely successful
31
What is an ageing population?
A decrease in the number of economically active people in the population- There are more elderly dependents (people aged 65 and over)
32
CASE STUDY- ageing population
UK By 2050, the number of over 60s will have passed the number of under 25s for the first time Positive- A longer, more active retirement, Some older people will have disposable income because they have paid of their mortgages ect, this boots the economy, Som physically fit older people volunteer and give back to society Negatives- Have to pay out pensions for longer, Strain on health care and care homes, Strain on our shrinking workforce of adults and a shortage of skills, Grown up children end up caring for their parents Solutions- More nursing homes and care workers, Educated and skilled migrants should be encouraged into the country to fill labour shortages, Country could adopt a pro natal policy
33
Migration
The movement of people from one region or country to another
34
Emigration
People (emigrants) leaving a region or a country
35
Immigration
People (immigrants) entering a region or a country
36
CASE STUDY- large scale migration
Polish migration to the UK Poland is situated in eastern Europe. Circular migration is the main type of migration that occurs with Polish migrants Push factors- Employment in Poland in at 40%. Housing shortages Pull factors- Unemployment in Uk at only 5%. High demand for skilled labour. Higher earnings. Impacts (UK)- £2.5 billion contributed to economy, new migrants are typically hardworking, means UK is less likely to have an ageing population. Demand for housing leads to higher rent, increased pressure on education, disagreements between different cultures Impacts (Poland)- Wages being sent back to Poland, extra money has improved health services and education,returning migrants bring back new skills, brain drain of skilled workers, gender imbalance-less men so fertility rate is dropping, reduced size in countries work force
37
Explain why is Europe there is predicted to be a large population decrease
as low birth rate and high death rate low birth rate- educated female population, contraception, expensive to raise children higher death rate- ageing population
38
Explain why it is predicted what there will be a slight increase in population in China
small increase due to lower birth rate and death rate - due to one child policy
39
Explain why it is predicted what there will be a large increase in population in the USA and India
highbirth rate low death rate
40
Explain the attractions of living in rural areas in the UK
small village- low density of housing open space attractive buildings countryside low levels of pollution low levels of stress, quiet, community spirit
41
Explain why Western European countries face an increasingly ageing population
Birth rates are decreasing due to: - greater number of women having careers and putting off having families until later - Desire for couples to have children decreases as cost of having children increases also - People are living longer due to improvements of healthcare, nutrition and living conditions - In UK for example, over 20% of population is over 60- this is forecasted to rise to almost 30% by 2050
