One of the major uses of national income statistics in Nigeria is to

Step 1: Analyze the question The question asks about a major use of national income statistics, which are figures like GDP, GNP and NNP that measure the total value of goods and services produced in an economy.

Step 2: Explain the concept National income statistics are used to:

• Measure the level of economic activity and growth
• Compare living standards over time or between countries
• Estimate per capita income (national income ÷ population)
• Guide government planning, budgeting and policy
• Show how income is distributed across sectors

Step 3: Evaluate each option

• A. Equally distribute national income among citizens. Wrong. The statistics only measure income. They do not distribute it, and equal distribution is not their purpose.
• B. Determine the total population. Wrong. Population is determined by a census, not by national income data.
• C. Compare population growth among nations. Wrong. Population growth is measured with demographic data such as census and birth/death rates. National income data compare output and income, not population growth.
• D. Estimate per capita income. Correct. Per capita income = National Income ÷ Total Population. It is a direct and major use of national income figures, and it serves as a rough indicator of the average standard of living.

Step 4: Answer The correct option is D. Estimate per capita income.

Tip: When you see "national income statistics", think "per capita income, standard of living, economic growth, and planning". Be careful with options that mention population. Population comes from a census, and national income only becomes "per person" when it is divided by population.
