Page 3: Population Studies. Population Growth Current population

Population Explotion

Population Cycle

                                                       

Page 5: Population Studies. Population Growth Current population

Key terms to help understanding

• Natural increase – means the population is growing because there are more people being born than are dying.

Page 6: Population Studies. Population Growth Current population

Fantasy Island has a population of 5.

Page 7: Population Studies. Population Growth Current population
Page 8: Population Studies. Population Growth Current population

What is the natural increase?

Page 9: Population Studies. Population Growth Current population

When the birth rate line is above the death rate line the population

is growing.

Page 10: Population Studies. Population Growth Current population

Stage 1

• Birth rate and death rate are high - low natural increase - low total population

Page 11: Population Studies. Population Growth Current population

Stage 2

• Birth rate is high - death rate is falling - high natural increase (population growth)

Page 12: Population Studies. Population Growth Current population

Stage 3

• Falling birth rate - low death rate - high natural increase (population growth)

Page 13: Population Studies. Population Growth Current population

Stage 4

• Birth rate and death rate is low - low natural increase - high total population

Page 14: Population Studies. Population Growth Current population

What causes change in populations?

- food supply - war - technological development - health - education - place of women in society

Population distribution (how we spread out over the world) varies

over time.

• What this really means is that people may have gathered in certain areas for certain reasons in the past and now they have moved because the circumstances have changed.

Page 17: Population Studies. Population Growth Current population

Why is population distribution uneven?

• We don’t like– Too wet– Too dry– Too high– Too humid– Too steep

So we tend to all gather in the nice places.

According to the Syllabus

Social

Historical

Resources

Terrain

We will mention these in case studies.

within Brazil.

Why a higher density on the coast?

• Portuguese trading towns started here.

• Employment and enjoyment in these cities as they grew – Rio de Janeiro – Sao Paolo

Why a higher density on the coast?

• Portuguese trading towns started here.

• Employment and enjoyment in these cities as they grew – Rio de Janeiro – Sao Paolo

• Climate more suitable

• Dense rainforests called “ Green Hell”
