1. Population growth rate
Population change
Learning objectives: Describe and explain:
How has the world’s population changed over time?
What are the main factors influencing population change?
Key words:
Population
Population growth rate
Migration

2. Earth clock What is the population at the start of the lesson?
Write it down in your books!

3. Task: Draw a line graph to show population growth from 1804-1999
Do not forget:
Title, labels, accuracy!
Do the X axis from 1800 to 2100!

4. Natural population change
Overall population change
The rate of natural increase:
Birth rate – the death rate
Usually this is calculated per 1000
Therefore as a percentage you need to divide by 10.
e.g. natural population increase is 40.2 per thousand
The percentage is 4.02%

5. Overall population change
Migration: The movement of people from one country to another. The number of people will either be ± or – depending on whether more people have left or arrived!
Birth rate
9.88 births/1,000 population (2014 est.)
Death rate
9 deaths/1,000 population (2014 est.)
Net migration rate
7.24 migrant(s)/1,000 population (2014 est.)

6. Earth clock What is the population at the start of the lesson?
Write it down in your books!

7. Malta: BR: 10.3 PER 100 DR: 8.3 per 1000 Net migration: +2.0
Calculate the natural population change and overall population change for Malta
Answer:
NIC: 2 per 1000 = 0.2%
OC: = 4.0per 10000
=0.4%
Malta: BR: 10.3 PER 100 DR: 8.3 per 1000 Net migration: +2.0

8. The demographic transition model
l/o: To explain how we can use the demographic transition model to predict population trend
What does this graph show us?
Why do you think this is happening?

10. Key terms: Birth rate: Death rate: Natural population increase:
Life expectancy:
