2. account for the variation in world population.

CONTENTS OF THE LESSON

FOCUS LESSONS

MEANING OF POPULATION

Population is the total number of people living in a particular place using a country.

WORLD POPULATION SIZE 

The current population of World in 2023 is 8,045,311,447, a 0.88% increase from 2022. The population of World in 2022 was 7,975,105,156, a 0.83% increase from 2021. The population of World in 2021 was 7,909,295,151, a 0.87% increase from 2020.

WORLD POPULATION DISTRIBUTION PATTERNS

Population distribution means the pattern of where people live. World Population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live.

WORLD POPULATION DENSITY

Population density is a measure of how densely populated an area is. It is calculated by dividing the total population of an area by its total land area.

The map shows the number of people per square kilometer (km2) across the world. Globally the average population density is 62 people per km² in 2023, but there are very large differences across countries.

WORLD POPULATION STRUCTURE 

Population structure is how a population can be broken up or distributed. This includes gender, age, ethnicity and density.

The three types of population structure are:

• Expansive (a young population and is growing)

• Stationary (there is neither increase nor decrease in population)

• Constrictive (an aging population, decreasing)

FACTORS AFFECTING POPULATION DISTRIBUTION

1. Climate

2. Relief

3. Soil

4. Water

5. Minerals, etc.

LESSON PRESENTATION

TEACHER’S ACTIVITIES

The teacher,

1. uses maps, diagrams, pictures, documentary films, etc. to guide students to discuss world population with respect to size, density, structure and distribution patterns.

2. guide class discussions on the influence of climate, relief, soil, water, mineral resources, etc. on population density and distribution.

3. leads students to make sketches of world population distribution on a map.

4. write notes on the board for students to copy.

 

 

STUDENT’S ACTIVITIES

The students,

1. watch films on population distribution.

2. listen to teacher’s explanations ask and answer questions.

3. Participate in class discussions.

4. draw sketch maps shows distribution of world’s population.

5. copy the board summary.

LESSON EVALUATION

Teacher asks students to,

1. use sketch maps to describe population size, density, structure, distribution patterns.

2. identify factors accounting for world population distribution patterns.

3. explain influence of these factors on population distribution.
