Lessonup!

Repeat paragraph 3.4 + 3.5. 

Learning goals: 

- You know why some places are crowded and some places aren't. 

- You know why the world population is growing more than ever. 

- You know what the terms population distribution and population density mean. 

Population distribution

Population distribution: The pattern of where people live in an area.

Densely populated: Many people live close to each other in these places.

Sparsely populated: Few people live in these places.

Population density: The number of people per km2

Amount of people living on a km2

1. Population
2. Inhabitants
3. Population density
4. Population distribution

Population

Population-
distribution

Population-
density

The population of the Netherlands is  17 million 

Half of the Dutch population live in the Randstad

Less people live in China compared with the Netherlands if you consider the size of the country's and inhabitants. 

Population density is ...

The .... amount of people that live per ... in a certain area.

1. highest ... city
2. highest ... square kilometre
3. average ... square kilomter
4. average ... city

What is the description of population density?

1. The number of people living per square kilomtre
2. The number of people living in a country
3. The average number of people living in a place, per square kilometre
4. The number of people living per square kilometre, on average

The population of a country is 6,400,000.
The surface area is 40,000 km2.


What is the population density?

1. 16
2. 160
3. 1600
4. 1,6

In the Netherlands 17,000,000 people live on a surface area of 41,500 km2. Calculate the population density and show your calculation!

Sparsely populated area

Densely populated area

• What does the map say about population density?
  
• What does it say about population distribution?

Population growth #1

Natural population growth

Number of births

Number of deaths

Natural increase: The difference between births and

deaths, given as a percentage.

Population growth #2

Immigration - emigration = migration rate

Net migration: The difference between the number of

immigrants and emigrants.

Why does the population grow this fast?

1. Better agriculture
2. Better medicine
3. More space
4. More diseases.

Densely populated

Sparsely populated

Population distribution

The way people are spread out over a given area is called: 'population distribution'

Can you explain the population distribution that you can see on the map? 

Population density

The population density is the average number of people living in a given area. 

Can you explain the difference in population density that you can see on the map?

Population density

Always calculate the population density using a square kilometre (km²)

How to calculate?: 
Number of people / square kilometres in an area. 

Population distribution

The way people are spread out over a given area is called: 'population distribution'

Can you explain the population distribution that you can see on the map? 

Population density

The population density is the average number of people living in a given area. 

Can you explain the difference in population density that you can see on the map?

Population growth

There is a difference between family size around the world. 

Usually families in poor countries are larger than families in rich countries. 

What are we going to do?

- Repeat previous terms we've discussed. 

- Take a look at population graphs 

- Why do poor countries have larger families. 

Learning goals:

You know and understand what population graphs are. 

You know how to read the population graphs. 

- You understand why there are larger families in poor countries. 

The Netherlands

China

Population growth

There is a difference between family size around the world. 

Usually families in poor countries are larger than families in rich countries. 

Why is there a difference? 

In a poor country: 

- You will have a higher status if you have many children. 

- Children can earn money for their parents, even when they are old. 

- People use fewer means to prevent having children. 

- Many children die at a young age. 

Population graph

It is possible to see the kind of population a country has, by using a population graph. 

The Netherlands

Malawi

Population graph

These graphs can tell us alot about the population and the future of a country. 

But how? 

High population density

1.

2.

Low population density

1.

2.

Low relief

Lot of precipitation

High relief

Dry and cold

Migration

In the case of Salim he moved from the north of India to Mumbai. He went to live in another place. We call this migration

Migration

When someone, like Salim, moves inside the same country we call this
internal-migration

Emigration

Some people leave the country to move to antoher country, we call this international-migration. 

Emigration

When you leave a country we call it emigration. When someone come and live permanently in a foreign country we call is immigration.

Terms

What is the difference between immigration and emigration? 

Explain the term internal-migration.

Give and example of migration.

Reasons to move

People have reasons to move. 

Push: reasons to leave a place.

Pull: Reasons to go to a place.

Economic reasons

People that can't get a job in the country of region they live in.

Political reasons

People that flee from a war of they are persecuted in their own country so they have to move. 

Environmental reasons

People that leave their country because of a natural disaster, like a hurricane or a earthquake. 

Terms

Emigration
Immigration (inmigration)

Internal-migration
Economic reasons
Political reasons

Environmental / ecological reasons
