Is there a pattern to a country s population

Is there a Pattern to a Country’s Population?

  • Learning Outcome:

  • All Learners: Will be able to identify the main features of a for a Demographic Transition Model and a Population Pyramid.

  • Most Learners: will be able to identify the

  • Literacy target:

  • To decode a piece of text in order to critically evaluate its effectiveness.

  • Competence: Research


Rate of population change

Rate of Population Change

Rate of change

  • Births and deaths are natural causes of population change. The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate.

  • Task:

  • In groups, discuss what the information on the board shows.

  • One person to lead the group

  • Copy spider diagram and complete notes:

  • .

Natural increase = birth rate - death rate

Rate of Population Change

MEDC

LEDC


Mini plenary

Mini Plenary:

  • Discuss the ways of collecting information about a population e.g. number of babies

How reliable was this in the past?

How about LEDC Countries?

Learning Outcome:

To be able to understand if there are patterns in a countries population.

Demographic transition model

Demographic Transition Model

Aim: To understand how the population of a LEDC country with high birth rate and high death rate can change over time

  • Task:

  • 5 stations (5 stages of the Demographic Transition Model)

  • For each stage, make notes in your book.

  • Use your copy of the DTM model to help you.


Station 1

Station 1)

Stage 1 Example Countries:

Sierra Leone; Congo – these are the poorest LEDC Countries.


Stage 1 birth death rate information

Stage 1) Birth / Death Rate Information


Youtube watch v 16brih5zfoy

Station 2)

Stage 2 Example Countries:

Bangladesh; Nigeria

  • Stage 2 - Early Expanding

  • Birth Rate remains high. Death Rate is falling. Population begins to rise steadily.

  • Reasons

  • Death Rate is falling as a result of:

  • Improved health care (e.g. Smallpox Vaccine)

  • Improved Hygiene (Water for drinking boiled)

  • Improved sanitation

  • Improved food production and storage

  • Improved transport for food

  • Decreased Infant Mortality Rates

  • Example countries:

Station 3)

Stage 3 Example Countries:

India; South Korea

  • Stage 3 - Late Expanding

  • Birth Rate starts to fall. Death Rate continues to fall. Population rising.

  • Reasons:

  • Family planning available (contraception)

  • Lower Infant Mortality Rate

  • Increased factories reduces need for workers i.e. machine do the work.

  • Increased standard of living (people are getting wealthier and have some healthcare)

  • Changing status of women (i.e. they get careers)

Stage 3) Birth / Death Rate Information

Station 4)

Stage 4 Example Countries:

More Economically Developed countries e.g. UK; France

Stage 4 - Low Fluctuating

Birth Rate and Death Rate both low. Population steady.

Typical of USA; Sweden; Japan; Britain

Population pyramids

Population Pyramids

Research Task:

Working in groups, you are going to answer the following questions:

A Population pyramid is…?

It shows….?

It is useful because…?

  • Group Roles:

  • Researcher (Ipad)

  • Information Gatherer (Research Board)

  • Speaker

  • Recorder

Clue 1) Population Pyramids show…?

Male Bar Graph

This is a simple bar graph which shows the number of people at a certain age.

This axis is for the Age:

Clue 2) A Population Pyramid shows…?

Population

Pyramids

Population structure means the "make up" or composition of a population. Looking at the population structure of a place shows how the population is divided up between males and females of different age groups.

Population structure is usually shown using a population pyramid. A population pyramid can be drawn up for a whole country or an individual town, city or village.

Clue 3) The Shape of a population

pyramid shows?

The shape of a population pyramid is very important and can tell us a lot about the people living in a particular country or place.

The shape of a population pyramid gives us information about birth and death rates as well as life expectancy


Youtube watch v 16brih5zfoy

Clue 4) Population Pyramids

A population with a high number of young dependants and a low life expectancy e.g. Mozambique.

Ageing population and a very low birth rate may have a population structure that looks a little like an upside-down pyramid e.g. Japan.

Falling birth rate and a rising life expectancy e.g. the U.K.

Looks like a barrel.

Peer Assessment:

WWW: They were able to accurately explain what a population pyramid is.

EBI: If they described the different stages of a population pyramid.

Population Pyramids:

  • Task:

  • Describe each sector of each graph (label sheet)..

  • Extension Question:

  • What does the pyramid show?

  • What are the benefits of this?

  • What are the drawbacks of this?


Youtube watch v 16brih5zfoy

Why do we get different population pyramids?

  • Thinking points:

  • Are all countries rich or poor?

  • Do some countries have a higher birth rate?


Youtube watch v 16brih5zfoy

  • Analysing population pyramids

  • Key things to know about population pyramids

  • The shape of a population pyramid can tell us a lot about an area's population.

  • It gives us information about birth and death rates as well as life expectancy.

  • A population pyramid tells us how many dependants there are. There are two groups of dependants; young dependants (aged below 15) and elderly dependants (aged over 65).

  • Dependants rely upon the economically active for economic support.

  • Many LEDCs have a high number of young dependants, whilst many MEDCs have a growing number of elderly dependants.

  • How do pyramids change over time?

  • A population pyramid that is very triangular (eg Mozambique in 2000) shows a population with a high number of young dependants and a low life expectancy.

  • A population pyramid that has fairly straight sides (more like a barrel) shows a population with a falling birth rate and a rising life expectancy.

  • Over time, as a country develops, the shape changes from triangular to barrel-like.

  • Places with an ageing population and a very low birth rate would have a structure that looks like an upside-down pyramid.

  • Recap of work on DTM model and population pyramids showing how countries at different stages of the DTM model have different population structures.

  • Discuss how the dependency ratio in a country can be worked out from a population pyramid (number of children under 15 plus number of adults over 65 multiplied by 100 divided by number of adults between 16 and 64). Discuss the assumptions the dependency ratio appears to be based on.

  • Describe how sketch pyramids can be drawn to represent the four stages of the DTM. Hypothesise and draw a fifth stage.

  • Introduce the ideas behind the Rostow Model. Students illustrate the ideas with a diagram.

  • Students write a detailed, illustrated report describing and explaining how the population structure of a country changes shape as it becomes more economically developed.

Learning Outcome:

To be able to understand if there are patterns in a countries population.


Is there a pattern to how a country s population changes over time1

Is there a pattern to how a country’s population changes over time?

  • Draw and label an outline of the Demographic Transition Model (DTM). Label and explain what the graph shows

  • Apply the DTM to an LEDC e.g. Sierre Leone and an MEDC e.g. UK. Research task.
