How can we model population change?

Goals:

At the end of these two classes you:

- understand how to interpet different population charts

- understand how changes to birth and death rates can be modelled

- understand how differences in the share of different age groups tot the total population can lead to demographic pressure

How can we model population change?

You need the following sources of information to answer the questions on the next slides. Open them in Google Classroom.

Read the text about population pyramids on p. 95 in the I&S Book.

According to this text, describe what a population pyramid shows.

Read the text about population pyramids on p. 95 in the I&S Book.

1) List two reasons why population pyramids/charts are valuable to demographers.
2) List one limitation that demographers could have when studying population charts.

Check out Figure 4.15 and 4.16 on p. 95 in the I&S Book.

1)Name the shape of the population chart in Figure 4.15
2)Name the shape of the population chart in Figure 4.16

Check out Figure 4.15 and 4.16 on p. 95 in the I&S Book.

Describe how you think the population chart in Figure 4.15 will look like in 2050.

Check out Figure 4.15 and 4.16 on p. 95 in the I&S Book.

With the help of Figure 4.16, explain the difference in life expectancy between men and women in Italy.

Check out Figure 4.15 and 4.16 on p. 95 in the I&S Book.

Do these population charts show relative or absolute numbers? Explain your answer.

Read G143 on p. 96 of the GeoGuide.


Describe the key word: demographic transition

Read p. 94 in the I&S book and G143 on p. 96 of the GeoGuide.


Describe what the demogrpahic transition model shows.

Use Figure 5.10 on p. 97 of the GeoGuide

For each of the five phases in the demographic transition model, describe the (change of) birth rates and mortality rates.

Use Figure 5.10 on p. 97 of the GeoGuide

For each of the five phases in the demographic transition model, describe the natural population growth.

Use Figure 5.10 on p. 97 of the GeoGuide

For each of the five phases in the demographic transition model, describe the reasons for changes in birth rates.

Use Figure 5.10 on p. 97 of the GeoGuide

For each of the five phases in the demographic transition model, describe the reasons for changes in mortality rates.

Read G143 on p. 96 in the GeoGuide.
Also, check out Figure 5.10

For each of the five phases in the demographic transition model, name the shape of the population chart that fits best.

Check out Figure 5.10 in the GeoGuide and use the internet.
1) Look up and give the most recent birth and mortality rates of the following countries..
a) South Korea
b) Uganda
c) Pakistan

2) In which phase of the demographic transition model would each county be?

Watch the video about population charts and
demographic transition.

List three things you did not know before, but
after watching the video you do know now.

Watch the video about 2060 and
the world population pyramid.

Which age groups are represented the most in the
world population chart of 2060?

PYRAMID

GRENADE

URN

low/very low birth and death rates

falling birth and slowly falling death rate

Phase 1 + 2

better medical care and food + less children needed

better medical care and water supply + low infant mortality

birth control, good health, improved position of women

disease and hunger + poor knowledge of medicine/hygiene

high birth rates and high or rapidly falling death rates

good healthcare and reliable food supply

Phase 3

children to support family, high infant mortality, no family planning

Phase 4+5

Read G144 on p. 97 of the GeoGuide

List the three groups the population of an area can be divided into and give their age structure.

Read G144 on p. 97 of the GeoGuide

Give a definition to the following key-word: 'economically active' or 'productive population'

Read G144 on p. 97 of the GeoGuide

1) Give a definition to the following key-word: demographic pressure
2) Describe what the word 'pressure' in this context means

Read G144 on p. 97 of the GeoGuide and check out Figure 5.9

Describe the difference between green pressure and grey pressure.

Read G144 on p. 97 of the GeoGuide and check out Figure 5.9

Population ageing increases grey pressure (increasing 65+ over 20-65)
Rejuvenation increases green pressure (increasing 0-20 over 20-65)

How many percent did the grey and green pressure in the Netherlands change between 1950 and 2010?
