Topic: Population and Labor Market
Sub-topic: Determinants of Population Size and Growth

Specific Objectives:

By the end of this lesson, learners should be able to:

1. List and explain the major determinants of population size and growth
2. Analyze how birth rate, death rate, and migration affect population size
3. Calculate population density using a simple formula

 

A – Anticipation (Engage learners)

Start with a class poll:

“If 100 people are born in a town this year, 50 people die, and 30 leave the town, what happens to the population?”

Show a short video clip or an infographic illustrating Liberia’s changing population numbers over the last two decades.

Pose this question to students:

“Why are some countries growing rapidly while others are shrinking?”

 

B – Building Knowledge (Core Content)

1. Determinants of Population Growth

• Birth Rate:
  This refers to the number of births per 1,000 people in a given year.
  A high birth rate leads to population growth.
• Death Rate:
  The number of deaths per 1,000 people in a given year.
  A low death rate leads to an increase in population.
• Migration:
  The movement of people from one location to another.
• Immigration increases the population
• Emigration reduces the population

2. Other Factors Influencing Population Growth

• Fertility rate
• Health care availability
• Cultural and religious values
• Government policies (e.g., child allowances or restrictions)
• Education, especially of women

 

3. Population Density

Definition: The number of people living per unit area, often per square kilometer.

Formula:

Population Density=Total Population

                                Land Area (km²)

Example:
If Liberia has a population of 5,200,000 and a land area of 111,370 km²:

 

This means there are approximately 47 people per square kilometer in Liberia.

 

C – Consolidation (Application and Reflection)

Class Exercise:

Using data provided by the teacher or from a textbook, students should:

• Identify whether the country’s population is increasing or decreasing
• State possible reasons using birth rate, death rate, and migration data

Group Discussion:

Discuss in small groups:

“What would happen if Liberia had a birth rate that doubled in the next 10 years but its healthcare did not improve?”

Practice Calculation:

Calculate the population density of a country with 10 million people and a land area of 200,000 km².

 

Assignment:

• Interview an elder in your community and ask them what they think has changed in Liberia’s population in the last 30 years. Write a short reflection (100 words).

 

Teacher’s Reflection:

• Were students able to compute population density confidently?
• Could learners clearly distinguish between birth rate, death rate, and migration?
• Were the discussion groups active and insightful?
