Rationale for the Lesson

Understanding the population of Nigeria helps pupils to know the size, characteristics, and movement of people in their country. This knowledge is important for planning and resource allocation, affecting various aspects of their daily lives and national development.

Prerequisite/Previous Knowledge

Pupils have some general knowledge of human settlements and basic geographical terms from earlier classes.

Lesson Content/Board Summary

POPULATION OF NIGERIA

1. Definition of Population

Population refers to the total number of people living in a particular area at a specific time.

2. Population Concepts

Population concepts include:

• Over-population: A situation where the available resources are insufficient to support the existing population comfortably.
• Under-population: A situation where the population is too small to fully utilize the available resources of an area.
• Optimum population: A situation where the population size is ideal, allowing for the maximum utilization of resources to achieve the highest standard of living.

3. Population Distribution

This refers to the way people are spread over a given area. Population distribution in Nigeria is uneven, with some areas being densely populated and others sparsely populated.

The following are factors influencing population distribution:

• Climate (rainfall, temperature)
• Relief (mountains, plains)
• Soil fertility
• Economic activities (mining, industries, agriculture)
• Government policies
• Historical factors (slave trade, inter-tribal wars)

4. Population Structure and Quality

Population structure refers to the composition of a population in terms of age, sex, and occupation. It is often represented by a population pyramid.

The following are characteristics that define population quality:

• Education level
• Health status
• Skill acquisition
• Income level

5. Migration and Population Movement

Migration is the movement of people from one place to another with the intention of settling permanently or semi-permanently.

The following are types of migration:

• Internal migration: Movement within the same country (e.g., rural-urban, urban-rural).
• International migration: Movement between different countries (e.g., immigration, emigration).

The following are causes of migration:

• Economic factors (search for jobs, better wages)
• Social factors (better housing, education, healthcare)
• Political factors (wars, conflicts, persecution)
• Environmental factors (droughts, floods, natural disasters)

6. Population Data and Census

Population data refers to information about the characteristics of people in an area. A population census is the official, complete enumeration of a population at a given time.

The following are reasons for the importance of population census:

• Helps in planning for social amenities (schools, hospitals).
• Assists in economic planning and resource allocation.
• Used for political representation and constituency demarcation.
• Provides data for research and development.

7. Sources and Problems of Population Data

The following are sources of population data:

• Population census
• Vital registration (births, deaths, marriages)
• Sample surveys
• Immigration and emigration records

The following are problems of population data collection in Nigeria:

• High illiteracy rate
• Superstitions and religious beliefs
• Political interference and manipulation
• Shortage of trained personnel and equipment
• Vast land area and difficult terrain
• Inadequate funding
