Comprehensive Syllabus Study Notes
• Population Distribution Factors:
- Densely Populated Areas: Coastal mining and commercial hubs (Accra-Tema, Sekondi-Takoradi), forest agricultural zones (Kumasi, Koforidua), and historic northern trading hubs (Tamale).
- Sparsely Populated Areas: The 'Middle Belt' of Ghana (parts of Afram Plains and Northern Region) due to historic slave raiding, tsetse fly infestation, poor road networks, and low rainfall.
• Population Structure: High birth rates produce a youthful population pyramid with a broad base, resulting in a high age dependency ratio.
• Rural-Urban Migration:
- Push Factors: Rural poverty, lack of potable water and electricity, erratic agricultural incomes, poor schools, and outmoded cultural practices.
- Pull Factors: Perceived white-collar job opportunities, modern hospitals, higher education, entertainment, and social amenities in urban centers.
- Urban Consequences: Slum expansion (e.g. Old Fadama / Sodom and Gomorrah in Accra), sanitation crises, traffic congestion, and youth unemployment.

Practical Example:
Kayayei (head porters) migrating from northern Ghana to wholesale markets in Accra illustrate economic push factors from dry rural districts.
Core Takeaway:
Dependency ratio = (Children 0–14 + Elderly 65+) divided by Working Population (15–64) multiplied by 100.
WAEC / WASSCE Examiner Tips
- Dependency ratio = (Children 0–14 + Elderly 65+) divided by Working Population (15–64) multiplied by 100.
Common Candidate Pitfalls & Errors to Avoid
- Writing crude birth rate as a percentage when it is a rate per thousand of the population.
- Defining the dependency ratio as children divided by workers, leaving the elderly out of the numerator.
- Confusing the birth rate (per thousand of everyone) with the fertility rate (per thousand of women of childbearing age).
- Adding births and deaths to get growth and forgetting net migration entirely.
- Reading a wide-based pyramid as an ageing population instead of a young, rapidly growing one.
