What does population mean?

Population

Learning ObjectiveTo identify what population means and the impact on the World.

-All pupils to identify what population means. -Most pupils can state how population can change. -Some pupils can start to identify what might influence population.

What 3 questions would you

like to answer

from the graph.

1. Annotate (label) the graph with

description of what has/is happening.

2. Now suggest why you think it has

happened.

The World Population

• What is the World’s Population?

• Is the World’s population increasing or decreasing?

• Draw a cartoon to describe the change in the World’s population.

• Research either on the Internet or through books:

What is the population of the US?

Bring it in for next lesson Make sure you note when this figure was from &

where you got the information from.

Population

Learning ObjectiveTo identify what population means and the impact on the World.

-All pupils to identify what population means. -Most pupils can state how population can change. -Some pupils can start to identify what might influence population.

Population Change

Learning Objective• To identify what natural change is and the

factors that influence it.

- All pupils to identify what birth and death rate mean.

- Most pupils can state a reason why the birth and death rate may increase and decrease.

Create your own image to explain the

Natural change in

Population

What influences Population?

Birth Rate

1.Find a Definition

2. Design a symbol to represent Birth Rate

Death Rate

1.Find a Definition

2. Design a symbol to represent Death Rate

What changes Birth and death rate?Change Does it increase or

decrease the birth or death rate? Use symbols

How does it change it?

Better Healthcare

A terrible war

Clean water is available

More women working

More healthy food is available

Deadly disease spreads

Birth control is provided

Think about the US’s population........

Do you think the population is increasing or decreasing?

(Remember: to gain the higher levels, you need to explain Why, How and use examples!)

Do you think the population is increasing or decreasing??

Population Density

Learning Objective- To learn why some places are densely populated

whilst others are sparsely populated.

- All pupils to define what densely and sparsely populated mean.

- Most pupils can identify reasons why people do or do not want to live in a place.

- Some pupils can identify places where there are high or low populations

Why are some places really crowded and others not?

What’s the density?

Some areas of the world are more populated than others.

We use population density as a measure of how many people live in a set area.

Population density is measured in people per square kilometre (km2).

Population density = Number of people/Area(km2)

India has a population of 1,103,371,000 and covers 3,287,263km2. The population density of India is 336.

What is the population density of England?

The population is 52,095,895

England covers 30395 kilometres squared.

Population density = Number of people / Area(km2)

What is the population

density of the U.S

High Density (densely

populated)

Low Density(Sparsely

populated)

Task Create 2 top

trump cards for why countries or areas would be

densely and sparsely

populated.

Where would you prefer to live : in a densely or sparsely populated

place ?Why?

Homework

• Using the website above write down 5 of your favorite facts and tell me why you like each one.

• For example. I like this fact because it shocks me how much

logging occurs in the World as the rainforest is very important to the wildlife and humans.

Population Density

Learning Objective- To learn why some places are densely populated

whilst others are sparsely populated.

- All pupils to define what densely and sparsely populated mean.

- Most pupils can identify reasons why people do or do not want to live in a place.

- Some pupils can identify places where there are high or low populations

Do the factors

increase or

decrease natural

change?

Lack of birth control/family planning

Famine causing lots of people to die due to lack of food

Parents wanting lots of children to help provide an income (such as working on

farms)

Disease (for example HIV/AIDS) causing lots of

people to die.

In many rural areas it can be the tradition to have lots of

children

Many young children die due to poor health care

No education about the benefits of a smaller family

War/Conflict

Government policies which want to strengthen their

population

Drug use, alcoholism and sexually transmitted diseases

(STD’s) is blamed for this change in .

Better health care Lack of resourcesPeaceful conditions within

the countryGovernment policies (such as

the One Child Policy in )

A culture which means men have a high status for having lots of children

Education about the benefits of a smaller family

Population Distribution

To investigate the population density of the US.

-All pupils can contrast between Population density and distribution.

-Most pupils can confidently interpret a choropleth map.

Density vs distribution

Density figures only tell us how many people live in an area.

The population can be evenly spread.

Often, distribution of the population is affected by factors of physical and human geography.

To describe the way people are distributed around an area we need to talk about the population distribution.

Alternatively, the population can be randomly distributed.

The population can also be clustered around one specific location.

When describing population distribution there are guidelines that should be followed.

Describe the obvious pattern. Where do most people live? What areas are most populated?

Give figures, if available, and locations. Using accurate figures helps support your description.

Give any exceptions to the ‘obvious pattern’. Are there areas that do no fit in with the general population distribution?

A choropleth map is a very accurate tool to use when describing population distribution.

Describing distribution

Keywords

Describe the population

distribution of the UK

Use HLGTA• H – Highest• L – Lowest • GT – General

Trend• A - Anomaly

Population density of U.S. - 2011

Group Task For the Choropleth map state 3 facts about

the pattern of population distribution in the U.S.

To reach the higher levels include: - Values e.g it is 2.5 – 6.3% - Compass Directions- Towns and Major cities (use an atlas to help you)

World Population DensityLearning Objectives-To explore areas in the world where there is a

dense and sparse population density.

-All pupils can state an area that is sparsely populated in the world.

-Most pupils can identify an area in the world that is densely populated and why.

-Some pupils can describe the world population density.

Reminder Population Density

• People are unevenly distributed around the world. The difference in distribution is measured by comparing population density - the number of people per square kilometre (km²) or sq. mile in the U.S..

• Population density is determined more by environmental factors which make an area more or less attractive to settlers than by economic development.

• The way in which people are spread across a given area is known as population distribution.

• Patterns of population distribution tend to be uneven. For example, in the US there are more people living in the northeast of the U.S. than in the West (eg.Montana).

Reminder Population Distribution

World Population Density – by countryWorld Population Density – by countryWestern Europe and Asia are densely populated

North America, South America and Africa have a low population density

Out of every 100 persons added to the population in the coming decade, 97 will live in developing countries.

Population Pyramids

• To explain what Population pyramids show us and how they may differ.

-All pupils can explain a population pyramid shows us.

-Most pupils can correctly analyse a population pyramid.

-Some pupils can compare the differences in pyramids for LEDCs and MEDCs, offering reason.

The Birth Rate , Death Rate and Life Expectancy

all affect the population structure

of a country.

What is this? What does it tell us about the population of a

place?

What is a population pyramid?• Population structure can be shown as a population

pyramid.

Features of a population pyramid.-Population is divided into 5 year age groups.-Population is divided into males and females.-The percentage/Number of each age /sex group is

given.

What can we find out from PP’s?

How would the population pyramid look if it was a developing

country (LEDC)?

Match the key words with the definitions

Population density

Is when there are relatively few people living in one area

Under/optimum population

When the number of people living in an area exceeds the amount of resources needed for them

the balance in population needed with the number of available resources

Sparsely populated

The number of people living within a given area

Population distribution

overpopulation

means the way or pattern in which people are spread across the world

Migration • To describe how migration can impact both negatively and positively on population.

-All to define migration and identify its various forms.-Most pupils can describe 2 ways migration can be viewed

as a positive in an area.-Some pupils can evaluate the negative aspects on a

population from migration and can begin to provide solutions to migration concerns.

Migration is the movement of people

from one place to another

It can be temporary, permanent, legal, illegal, internal and

internationalhttp://www.bbc.co.uk/learningzone/clips/why-young-people-move-to-cities-in-south-africa/1482.html
