Page 1: Population 6 - Trends In LEDCs

Key Terms

• Birth rate, death rate and natural change you should know already.

• Infant mortality rates – the number of children in a year who die before their first birthday per 1000 live births

• Life expectancy the average number of year from birth that a person is expected to live.

LEDC Population Issues

Rapid Population Growth and Youthful Populations

Why, what caused this?

Page 3: Population 6 - Trends In LEDCs

High Birth Rates in LEDCs

Page 4: Population 6 - Trends In LEDCs

• Children needed as workers and to look after parents when they are older.

• Infant mortality rates are high, so high birth rates compensate for this.

• It is hoped children will grow up`, move to the city and get a good job, then send money home.

• Religion often forbids the use of birth control.• Having a big family increase peoples status and

importance in their village.• People (women) do not have access to

EDUCATION and contraception

Why traditionally are BRs high in LEDCs?

Page 5: Population 6 - Trends In LEDCs

So for many years BRs in LEDCs were high – but what

also happened?

Death rates fell

Page 10: Population 6 - Trends In LEDCs

Why did death rates fall?• Improved health care as knowledge,

technology and medicines are imported from MEDCs.

• Cleaner and safer drinking water, again as systems are imported from more developed countries.

• Better diets as more food is grown, often as a result of improved farming techniques developed in MEDCs.

• All leads to better living conditions and less disease which results in people living longer and falling death rates.

High birth rate and falling death rate in

LEDCs =

population explosion

Page 12: Population 6 - Trends In LEDCs

And there is more

Page 13: Population 6 - Trends In LEDCs

Life Expectancy in LEDCs is Short

Page 14: Population 6 - Trends In LEDCs

• Lack of food and famine cause early death in many people.

• The spread of disease, for example cholera that comes from drinking dirty water, causes many deaths.

• Health care and hospitals are poor and often difficult to access.

WHY?

Page 15: Population 6 - Trends In LEDCs

So there are more and more people in LEDCs, and many of these people are young – the

populations are youthful

Population Pyramid

Page 17: Population 6 - Trends In LEDCs

What problems does this cause?

Page 18: Population 6 - Trends In LEDCs

Overgrazing and Overcultivation

As seen in the Sahel region of Africa

Page 19: Population 6 - Trends In LEDCs

Pollution

• Water pollution for example from human waste

• Land pollution for example from farming.

• For example from increased car use.

Especially in large rapidly growing

urban areas such as Jakarta in Indonesia.

Page 20: Population 6 - Trends In LEDCs

Deforestation and Soil erosion

For example in Amazonia

Page 21: Population 6 - Trends In LEDCs

Overcrowding and the growth of Shanty Towns

Favelas in Brazil Busties in India, e.g. Mumbai

Slums in Jakarta

Page 22: Population 6 - Trends In LEDCs

Traffic Congestion

In Bangkok

And Mexico City

Page 23: Population 6 - Trends In LEDCs

Other Problems

• Shortage of resources, food and raw materials.• Unemployment and underemployment.• Lack of money for basic health care and

schooling.• Rising crime, political coups and huge debts.• Low living standards and a lack of development.

What are the management solutions?

What do we have to change in order to manage the problems?

Page 25: Population 6 - Trends In LEDCs

Anti-natalist population policies

• Tanzania case study

• Kerela, India case study

• China, One Child Policy case study

• North Africa case study
