What is population

It means the number of people living in a certain area

2
New cards

What is a population pyramid

It shows the structure of a population

3
New cards

What is natural increase

It is when the birth rate is above the death rate

4
New cards

What is natural decrease

It is when the birth rate is below the death rate

5
New cards

What continent has the highest natural increase

Africa

6
New cards

What is birth rate

It is the number of live babies born per 1,000 per year

7
New cards

What is demographic momentum

The tendency for a population to continue growing even after fertility rates have declined, due to a larger proportion of people in their reproductive years.

8
New cards

What is death rate

It is the number of people who have die per 1,000 per year

9
New cards

What is the infant mortality rate

It is the number of babies who die within their first year of life per 1,000 per year

10
New cards

What is the carrying capacity

It is the largest number of people that the resources of the planet or a give area can support

11
New cards

What is over population

Too many people in an area that can be supported by its resources and technology.

12
New cards

What are the causes of overpopulation

  1. Low levels of education causing larger families

  2. Natural disasters, political unrest or war elsewhere causing in-migration to an area

  3. Lack of development & high levels of natural increase, maybe because of strict religious views so contraception isn’t used

13
New cards

What are the consequences of overpopulation

  1. Out-migration

  2. Starvation/famine or civil unrest

  3. Unemployment and poverty

  4. Overcrowding

14
New cards

What is underpopulation

Too few people in an area to utilize its resources available efficiently using current technology levels

15
New cards

What are the causes of underpopulation

  1. Difficult climate and weather

  2. Remoteness

16
New cards

What are the consequences of underpopulation

  1. High employment rates and high wages (to maintain workers but doesn’t always happen)

  2. In-migration (people see opportunity)

17
New cards

The Demographic Transition Model

What is the Demographic Transition Model (DTM)

It shows how the population of a country changes throughout economic development as birth and death rates change.

21
New cards

How many stages are in the demographic transition model

5

22
New cards

What happens to economies in stage 1 of DTM

  • Birth rates are very high because there is high infant mortality rate and no access to contraception like condoms because they are very poor.

  • The death rates are also high because there are not many doctors, hospitals and no schools to educate people on diseases and how they spread.

23
New cards

What happens to economies in stage 2 of DTM

  • The death rate begins to fall because people’s understanding of diseases have improved and they are educated on how to improve their health systems.

  • Birth rates are still high because people do not know yet their children are likely to live longer. This also occurs because these nations usually have lots of jobs in agriculture and having lots of children is beneficial.

24
New cards

What happens to economies in stage 3 of DTM

  • The birth rates begin to fall to the level of death rates

  • Improved access to contraception, belief that children will survive to adulthood and increased female education

  • Healthcare systems continue to improve

  • Most stage 3 economies like Vietnam and India focus on manufacturing, so having lots of children to work on farm reduces

25
New cards

What happens to economies in stage 4 & 5 of DTM

  • Birth rates are low because of low infant mortality, good access to contraception and equality of access to education

  • Death rates are low because of good healthcare systems, high levels of education and high incomes

26
New cards

What is an example of a HIC economy that is in stage 5 of the DTM and is declining in population

Japan

27
New cards

What are examples of countries in stage 5 of the DTM

Germany and Japan

28
New cards

At which stage of the DTM is the economy most dominated by agriculture

Stage 2

29
New cards

What is the most developed stages of the DTM and why

Stages 4 & 5 because most HIC are in these stages

30
New cards

What are the 3 types of factors influencing birth rate of a country

Economic, political and social

31
New cards

List economic factors influencing birth rate

  1. Poorer countries have higher fertility rates as children are considered good labour because they work in fields .

  2. In the LEDCs, there are no pensions available for older people so children are expected to provide for their parents.

  3. In HICs birth rates are lower as couples decide that children are expensive.

32
New cards

List political factors influencing birth rate

  1. Government policies can affect birth rate

  2. Countries with ageing populations have pro-natalist policies to encourage women to have children

  3. Countries with huge populations that are increasing rapidly may limit the number of children allowed

33
New cards

List social factors influencing birth rate

  1. Tradition demands high birth rate as a measure of social status so birth rate remains high

  2. Education for women reduces the birth rate as they have a greater knowledge of birth control and more chances of work or a career

  3. Strict Muslim and Catholic societies do not permit the use of contraception so the birth rate is generally higher

  4. In HICs, couples marry later so start families later, this limits the number of children produced

34
New cards

Examples of countries with pro-natalist policies

France made a policy called “Code de la famille”

35
New cards

When did the France pro-natalist policy start

1939

36
New cards

What were the gifts given to families in France for having a third child

  • Paid up to ÂŁ1064 for having a third child.

  • Three-child families were given family allowances to increase their buying power.

  • Mothers were given maternity pay (at nearly full pay) for 20 weeks for their first child and for 40 weeks or more for a third child.

  • Preferential treatment when bidding for council flats with three bedrooms.

  • Three-child families got a 30% fare reduction on all public transport.

  • Mothers and housewives received a full pension scheme.

37
New cards

Examples of countries with increasing huge population that may limit the number of children allowed

China have a One Child policy of 1979-2015

38
New cards

What were the gifts given to families in China for having one child

  • Parents of one child received larger pensions.

  • Only children received the best education for free.

  • The legal age of marriage was raised to 22 for men and to 20 for women, and they had to have state permission.

39
New cards

What were the penalties for having more than one child in China

  • Parents had their benefits taken away.

  • The family’s income was fined by up to 15%.

  • Abortions became compulsory for a second pregnancy, and there was a lot of worry that many of these were forced abortions.

40
New cards

What were the impacts of the one child policy in China

  • 300 million births were prevented and China's population has stabilized at 1.4 billion people.

  • Accusations that China violated human rights with forced abortions and causing female infanticide because people would rather have a male child.

  • The current ratio of men to women is 118:100.

  • The current fertility rate (1.6) is below the replacement rate of 2.1, leading to an ageing population.

  • By 2040, the ratio of worker to retiree will be 2:1.

41
New cards

What are the 2 main factors influencing death rate of a country

Education and health-related factors

42
New cards

List ways education influence death rate

  • The best-educated people generally live in the most developed nations and they have the highest life expectancies

  • The UK has a society which educates women whereas Nigeria does not

  • The key to developing a country is educating girls as this encourages fewer babies

  • Fewer children improves the standard of living for all as there is more food for all

43
New cards

List ways health influence death rate

  • After WW2, vaccines and cures for tropical diseases decreased death rates significantly around the world

  • Richer nations benefited first so their life expectancy increased significantly but most of the developing world has caught up

  • In LICs, people are more likely to die from poverty and lack of effective treatments from water-borne illness e.g. cholera, typhoid

44
New cards

What is migration

The movement of people from one place to another for a short period of time or permanently.

45
New cards

What is internal or national migration

The movement of people to a city within the same country

46
New cards

What is international migration

he movement of people to a city in a different country

47
New cards

What is labour or economic migration

The movement of people for economic gain

48
New cards

What is forced migration

The movement of people because of events such as a war which pose a sudden threat to people.

49
New cards

List push factors (factors that encourage people to leave an area)

  • People can't afford to repair damage caused by natural disasters.

  • Mechanisation of farming equipment means fewer jobs are available.

  • Desertification can make it hard for people to support themselves as the land becomes less productive.

  • People might be forced to flee their homes because of conflict.

50
New cards

List pull factors (factors that attract people to an area)

  • Urban areas provide more jobs, and jobs which are often better paid.

  • Health care and education are more easily accessible in urban areas.

  • The thought of joining other family members that have already moved.

  • There is a perception that urban areas provide a better quality of life.

51
New cards

What are the positive impacts on countries of origin

  • Unemployment may decrease.

  • If the migrants return after a few years, they may bring money and skills back with them.

  • There may be better life chances for young migrants

52
New cards

What are the negative impacts on countries of origin

  • Economic hardship may come about because of the loss of young workers.

  • Losing highly trained or skilled people, in particular health workers, can create problems for the countries of origin (brain drain).

  • There may not be enough people left to farm the land (food shortage).

  • Migration may cause social problems for children who are raised without parents.

53
New cards

What are the positive impacts on countries of destination

  • Migration leads to greater cultural diversity (more cultures sharing a home).

  • Economic growth (better standard of living) keeps going, even if the population is ageing.

  • There is the advantage of “brain gain” (increase in highly trained foreign-born professionals).

  • Job vacancies and skill gaps are removed.

  • The pension gap can be solved by new workers paying taxes.

54
New cards

What are the negative impacts of countries of destination

  • Lower wages may be offered.

  • Migrants may be forced to do the DDD jobs (dirty, dangerous and degrading) to make a living.

  • Public services like schools and hospitals may not be able to cope with the increase in population size.

  • If migration cannot be controlled, unemployment may increase.

  • There may be integration (mixing in), language or racism problems between the local people and the migrants.

55
New cards

What are the positive impacts of migration on migrants

  • There may be the opportunity of better pay for migrants.

  • There may be a better choice of jobs.

  • There may be better opportunities to improve skills, training or education.

  • Migrants may be able to learn new languages.

56
New cards

What are the negative impacts of migration on migrants

  • Migrants may suffer from loneliness or racist abuse.
