Sub-Topic 1: Distribution or Structure of Population
Population is distributed or structured into four: Geographical Distribution, Age Distribution, Sex distribution and Occupational Distribution.
Geographical Distribution:
This is the breakdown of the population of a country into different geographical zones. It shows the number of people that are living in the various parts of the country.
Factors Affecting Geographical Distribution of Population
- Concentration of Industries: People generally tend to move towards areas where industries, factories, or offices are situated. This is in hope of seeking employment in such places.
- Commercial Centres: Commercial activities going on in certain areas encourage population growth there. This is one reason why urban areas like Lagos, Port-Harcourt, Onitsha, Aba, etc are heavily populated.
- Topography and Fertility of Soil: Since farming is a major occupation of people of West Africa, farmers tend to settle in areas with good topography and where the soil is fertile for agricultural purposes.
- Climatic and weather condition: Some areas with friendly climate tend to be densely populated than areas with harsh climate.
- Age Distribution
This refers to how the total population is spread among the various age groups. We shall group the ages into three:
0-17 years – Dependent Population
18-60 years – Working Population or Labour force
60 and above – Dependent Population
