This document provides an overview of a geography unit on population for secondary school students. It will cover calculating population growth rates, density, and the factors that affect them. Students will learn about global and exponential population growth. They will also study the components of population change like birth rate, death rate, and rate of natural increase. The unit will examine factors influencing population distribution and density around the world. It includes examples, activities, and assessment questions for students.

1. Chong Boon Secondary School
Humanities Department (Geography Unit)
Lower Secondary Geography (Sec Two)
Prepared by Mr Kelwin Koh

2.  At the end of this unit, you will be able to
 Identify and calculate
▪ Population growth rate
▪ Rate of Natural Increase
▪ Population Density
 Identify the factors that affect population growth
 Identify the factors that affect population density

3.  The number of people who live on
Earth.
 Current global population stands at
about 7.1 billion humans.
 Population grows at an exponential
rate
 Rapidly increasing since the year 1000
AD

4.  Births – Deaths = Population growth
Births– Deaths = Population growth
Births – Deaths = Negative Population growth

5.  Birth rate
 Number of live births per 1000 people
in a year
 Death rate
 Number of deaths per 1000 people in a
year
 Rate of natural increase
 Birth rate minus Death rate

6.  Newborn that is
delivered alive.
 IMR (Infant Mortality
rate)
 Number of children who
die before 1 year of age /
1000 people
 Stillborn babies are
babies that are
delivered but already
dead.

7.  On average, 20 babies are born for
every 1000 people and 9 people die
for every 1000 people in a year.
What is the rate of natural increase?
 Birth Rate = 20
 Death Rate = 9
 Rate of Natural Increase = 20 – 9

8.  In your groups, discuss and write down on the
paper provided. (provide examples)
1. What are 3 conditions that will encourage
people to have a lot of children?
2. What are 3 conditions that will result in a lot
of deaths suddenly?

9.  Take a look at the following clips and write down
your feelings about them on the Leaf provided.
 Reflection Qn: How do you think your world will
be like in 2060?

10.  The spread of people in an area
Take a look at pg 10& 11 Figure
2.3
 Most of the global population is
located in ASIA
Which of the 7 Continents is the
least populated?

11.  The total number of people living in a square
kilometre of land.
Population density = Total population
Area

14. 1. Physical factors
2. Human and
Economic
factors

15.  Relief
 Flat terrain encourages growth
 Climate
 Harsh climate discourages growth
 Soil & Minerals
 Ease of cultivation and presence of minerals
encourage growth
 Natural Vegetation & Water
 Source of food and water encourages
growth

16. Agriculture
Natural resources
Industry
Commerce
Transport and Accessibility

17. A mining town casestudy

18.  Tin is discovered, a big company buys the
land and starts mining.
 Miners move into the town
 Brings families, children
 Schools and Hospital built
 Other amenities built
 Transport (road/ rail/ harbour) built to move
tin out (export)
 Other industries may grow due to the large
number of people

19.  When the tin is all gone
 Main employer in town now gone
 Lack of jobs for ex-miners
 Large scale departure from town
 No new industry to replace mining
 Town shrinks to old size
 IPOH, Peninsular Malaysia

21. 1. What is the most famous natural
resource from Ipoh?
2. Who is the most famous celebrity from
Ipoh in the past 20 years?
3. Name a local delicacy that has ‘Ipoh’ in
its name!
Submit all answers in the BOX by
next Monday.
3 lucky winners will get prizes!

22.  Let’s take a look at the following questions
1. Why is there a need for schools and
hospitals in every densely populated mining
town?
2. What are 3 other services that every mining
town will have. (provide an explanation for
the purpose of that service)
