18
Q
Describe stage 1 of the Demographic Transition Model and give an example
A
- High fluctuating stage - Ethiopia
►Very poor
►High birth and death rate
►Population may fluctuate or grow very slowly
19
Q
Describe stage 2 of the Demographic Transition Model and give an example
A
- Early expanding stage - Mali
►Economy begins to improve
►Better food and medical supplies cause death rate to fall
►But poor people still have large families so birth rate remains high
►Result is rapid population growth
20
Q
Describe stage 3 of the Demographic Transition Model and give an example
A
- Late expanding stage - Brazil
►Economy continues to improve and many people begin to plan the size of the family
►As the birth rate falls, the rate of population growth slows
21
Q
Describe stage 4 of the Demographic Transition Model and give an example
A
- Low fluctuating stage - Ireland
►Place at stage four is economically developed
►Most live long lives but have few children
►Means both death and birth rates are low
►Population fluctuates and increases only very slowly
22
Q
Describe stage 5 of the Demographic Transition Model and give an example
A
- Senile stage - Germany
►People are so concerned with material comforts that the have few children
►Population will decrease as the birth rate becomes smaller that the death rate
23
Q
How do you calculate population change?
A
Birth rate - death rate 100
———————- X —-
1000 1
24
Q
How can food supply increase population?
A
- With an increased food supply, health will also generally improve, allowing people to live longer.
- Over time, this will also lead to a decrease in death rate
25
How can food supply decrease population?
* During times such as famine or drought, a population will begin to decline
* People will either stave to death or their health will become poorer and they won't live as long
26
How can war increase population?
* People often seek refuge during times of war
* They flee their country and seek refuge in others
* Even though the population of their home country decreases, the other country's population increases because of the refugees
27
How can war decrease population?
* Soldiers and civilians die
* Husbands and wives separated leading to reduced birth rate
* Disrupts day-to-day life such as agriculture and health services and may affect populations health and may lead to death
28
How can technology increase population?
•New agricultural machinery can make growing food more efficient, meaning a country can grow more food, improving the populations health
29
How can technology decrease population?
* Guns, bombs and missiles can lead to deaths of thousands
| * New transport vehicles have led to the deaths of millions worldwide
30
How can health increase population?
* New developments in medicine lead to people living longer, healthier lives, reducing the death rate
* Fewer people die from easily curable diseases because of new medicine and an improved health service
31
How can health decrease population?
* Many people in developing world don't have access to modern medicine and a good public healthcare system
* They are therefore less healthy and may have shorter lives leading to a population decrease in that country
* Unclean drinking water in these countries can also lead to people dying from typhoid and cholera
32
How can education increase population?
* Couples who are uneducated may not have as good an understanding of family planning
* It is likely they will have large families, increasing population and birth rate
33
How can education decrease population?
* The more educated a person is, the more likely they are to practice family planning. Family planning reduces birth rates.
* Someone who is educated is more likely to pursue a career, so having a large family would be inconvenient
34
How can the status of women increase population?
* The lower the status of women in society, the less educated they probably are
* Because of this, they wouldn't have a good understanding of family planning and therefore may have many children, increasing the birth rate
35
How can the status of women decrease population?
* When the status of women in society is high, they are more likely to have an education
* They would understand the importance of family planning, bringing down thee birth rate
* Also, because of their education, they are more likely to pursue careers, so multiple children would be inconvenient
36
Describe a pessimistic view of population growth
Those who believe population explosion will continue for a long time are said to have a pessimistic view. These people believe world population will double within 40 years and will exert pressure on resources such as food and land
37
Describe an optimistic view of population growth
Those who believe population will decline as countries develop into later stages of economic development are said to have an optimistic view
38
Describe Brazil before the 1500s
○Population of 8 million
○Low population density
○They were hunter-gaterers
39
Describe what happened to Brazil from the 1500s to the 1800s
○In the 16th century, Portuguese colonists arrived and settled along coastal zones of Brazil
○Climate here suited them
○Grew sugar cane in north-east Brazil and coffee in São Paulo on large estates called plantations
○Many of native Indians working on plantations were wiped out due to exhaustion and disease
○As a result, African slaves were imported
○Plantations were often located on coast so goods could be exported
○These later developed into industrial cities like Rio de Janeiro and São Paulo
○When people moved to these cities for employment, population grew
40
Describe what happened in Brazil in the 19th and 20th centuries
○In the 19th and 20th centuries, European migrants came from Germany, Italy and Sweeden and settled in the cooler regions of the south-eastern coast of Brazil
○As a result, high population densities are found in this region
41
Describe what happened with the migration to the interior of Brazil
○During the 1960s, the government tried to encourage people to move to the interior of Brazil, in an attempt to reduce high population densities along the coast
○New capital, Brasilia, was built 1000km inland, in order to attract migrants, which would lead to the development of the interior
○New roads were built e.g Trans-Amazonian Highway
○Mineral resources e.g. iron ore reserves, were exploited
○Parts of the rainforest were destroyed to make room for grazing land for cattle
42
Why has it been difficult to develop the interior of Brazil?
→Thick jungle makes it hard to build infrastructure
→Very hot and humid in jungle
→This area has a hot and equatorial climate. It experiences high rainfall, humidity and temperatures. Exposed soils become eroded by heavy rain and infertile due to leaching, making them unsuitable for agriculture
43
What were the negative affects of developing the Amazon
→Native Amerindians were driven off their land and many died
→Plant species and animals destroyed as a result of forest clearance
→Rivers in this region often flood
44
Describe favelas
○Very unhealthy environments to live in with poor living conditions
○Lack of clean water, highly inadequate sewage facilities (if any) and poor building construction
45
What was the West of Ireland like before the Famine?
- Farmers subdivided their land into smaller plots allowing all sons to inherit land on farm
- Large families as a result of young people marrying early
- Ireland's food supply increased with the introduction of the potato as staple food.
46
Why did the Irish population decline during the famine?
- Failure of potato crop in 1845-1847 due to potato blight resulted in over 1 million people dying of starvation
- Emigration rose as young people emigrated to UK and US during and after the Great Famine
47
Why did the Irish population continue to decline 100 years after the Famine?
- Practice of subdividing land ended and it became tradition for the oldest son to inherit all the land. Often forced other sons to make their own living elsewhere, usually outside of Ireland
- Became normal to delay marriage until 20s. Having children later helped to decline population further still
48
How does climate affect population density?
Population density is greater in regions where the climate is favourable
49
How does relief affect population density?
Population density is greater on gently sloping areas or low lying areas. Mountainous regions experience low population densities because of its difficult physical environment, difficulty of economic actions and developing infrastructure
50
How does soils affect population density?
There is a greater population density in regions of fertile soils
51
How does mineral wealth affect population density?
Greater population densities in areas where deposits of coal, gold etc. are found
52
How does economic activity affect population density?
Where there is industry, employment prospects are good, attracting people to the area
53
How do urban areas affect population density?
Population density will increase where roads and services are available
54
What was the population of County Dublin in 2011?
1,273,069

57
Why is the development of South Dublin restricted?
Restricted by physical barrier of Dublin Mts. This prevents the city from spreading into the countryside
58
Why is the the expansion to north Dublin restricted?
Restricted by location of Dublin airport. Exception is along north coast of the county. Here the population densities have also increased e.g. Swords, Rush, skerries
59
