Among all the determinants of economic growth, the most important one is

Step 1: Analyze the question The question asks which factor is the most important determinant of economic growth. Economic growth is a sustained increase in a country's output of goods and services over time.

Step 2: Explain the concept The main determinants of economic growth are:

• Human capital: the skills, education, health and productivity of the workforce
• Physical capital: machinery, factories and infrastructure
• Natural resources: land, minerals, oil and so on
• Technology: better methods of production

Step 3: Evaluate each option

• A. Human capital: People organize production, use the resources, and develop and operate technology. Without skilled and healthy workers, other inputs are wasted. Many economists therefore treat human capital as the key driver of growth.
• B. Increased GDP: This is not a determinant. It is the measure or result of growth, so it can be eliminated.
• C. Land and natural resources: These help, but resource-rich countries (like Nigeria) can still grow slowly. Japan and Singapore have few resources yet grew rapidly through their people.
• D. Technologies: Technology is very important, but it is created and used by skilled people. It is a product of human capital.

Step 4: Answer This is option A.

Step 5: Exam tip If an option is the result of growth (like increased GDP), it cannot be the cause. Eliminate it first. Also remember: "Resources don't develop themselves, people do." In JAMB Economics, when asked for the "most important" factor of production or growth, human resources/labour is often the expected answer.
