Explain the uses of national income figures.

Answer Details

Concept. National income figures (such as GDP, GNP/GNI, and per capita income) are statistical estimates of the total value of goods and services an economy produces. Once compiled, they serve several important purposes.

Uses of national income figures.

• Measuring economic performance and growth. Comparing national income from year to year shows whether the economy is expanding, stagnant, or contracting.
• Indicating the standard of living. Per capita income (national income divided by population) gives a rough measure of average welfare in the country.
• International comparison. Figures allow the wealth and living standards of different countries to be compared.
• Aid to economic planning. Government uses the data to allocate resources, set targets, and prepare development plans and budgets.
• Showing the structure of the economy. Sector contributions (agriculture, industry, services) reveal on what the economy depends.
• Measuring income distribution. The figures help reveal how income is shared among groups and regions, guiding policies to reduce inequality.
• Assessing the effect of government policy. Changes in the figures show whether fiscal and monetary policies are achieving their aims.
• Basis for international obligations. Contributions to and grants from international bodies are often based on national income.

Note on limitations. The figures should be used with care because they ignore non-market activities, do not show income distribution directly, and are affected by price changes; real (not just money) figures and per capita measures give a truer picture.

Examination takeaway. Where the question simply says "explain the uses," give several distinct uses, each named and briefly explained, rather than one use discussed at length.
