  • Political stability. Countries which are relatively stable politically experience high production hence high national income level.
  • Accuracy of accounting systems. If the methods used to gather data are accurate, then the overall statistical figures will the accurate hence reliable.

Reasons why high per capita income is not an indicator of a better living standard in a country

  • Statistical problems. The collection of the national income data may be inaccurate meaning that the national income figures might be incorrect hence wrong per capita income.
  • Changes in money value. If the currency has been devalued, there can be change in the value of money without necessarily representing any changes in the welfare of the people.
  • Income distribution. The per capita may be high even though the income is in the hands of very few people thus it is not a representative of the majority.
  • Nature of products. If the products are not meant to satisfy immediate wants of the people, then an increase in per capita income may not lead to a higher economic welfare.
  • Peoples’ hard work and attitude. Increased national income may mean less sleep and more worries. People have no time to enjoy what they produce and their welfare may be low despite the rise in national income.
  • Social costs. People may migrate from rural areas to urban areas straining family relationships while an increase in industries may create pollution, congestion and other environmental disruptions.
