In developing countries, a larger percentage of the labour force is employed in the

Step 1: Analyze the question The question asks which sector employs the largest share of workers in developing countries like Nigeria, Ghana, and Sierra Leone.

Step 2: Explain the concept Economic activities are grouped into three main sectors:

• Primary sector: extraction of natural resources, including farming, fishing, forestry, mining, and livestock.
• Secondary sector: manufacturing and construction, which turn raw materials into finished goods.
• Tertiary sector: services such as banking, transport, education, health, insurance, and trade.

Trade is part of the tertiary sector, so options A and B overlap.

Step 3: Apply to developing countries Developing economies typically have:

• Low industrialisation, so the secondary sector is small.
• Underdeveloped service industries.
• Heavy dependence on agriculture, mostly subsistence and small-scale farming, which needs a lot of labour but little capital.

In Nigeria, for example, a large share of the working population is in farming, fishing, and related activities. As economies develop, labour shifts from the primary sector to the secondary sector and then to the tertiary sector.

Step 4: Eliminate options

• A. Trade sector: part of the tertiary sector, and not the largest employer.
• B. Tertiary sector: dominant in developed countries, not developing ones.
• D. Secondary sector: limited by low industrialisation.
• C. Primary sector: correct. Agriculture and related activities employ most of the labour force.

Tip: Remember "Developing = Digging and Dropping seeds." Poorer countries are mostly primary (agriculture), while richer countries are mostly tertiary (services). This pattern comes up often in WASSCE and JAMB Economics.
