Primary production is concerned with the extraction of raw materials through agriculture, mining, fishing, and forestry. Low-income countries are assumed to be predominantly dominated by primary production.
Secondary production concerned with industrial production through manufacturing and construction. Middle income countries are often dominated by their secondary sector.
Tertiary production concerned with the provision of services such as education and tourism. In high-income countries the tertiary sector dominates. Indeed having a large tertiary sector is seen as a sign of economic maturity in the development process.
The strengths of using this model is that it works for developed countries, more better than the undeveloped. This is because if a country is developed we could measure easily based on their economic growth in the four sectors.
However, this may be misleading. Some LDCs may have a large tertiary sector due to a large tourist industry without having developed a secondary industry. Economists argue that this could be somewhat risky. If the economic base is dominated by an economic activity such as tourism that has a high income elasticity of demand then a recession in the consuming nations will have a disproportionately large impact on the export earnings. A fall income will bring about a proportionately greater reduction in demand for the service and this will have severe impact on the economy. If it does not have a primary or secondary production to fall back on then borrowing and debt might be the only prospect.
Based on our information, we think that this model is only useful based on

Shows economic growth (employment rate in %) based on four different sectors • Primary • Secondary • Tertiary • Quaternary
Agriculture, mining, fishing & forestry Low-income countries
Education , tourism High income countries (most developed)

Good only for westernised countries (MEDC countries)
There are many less developed countries where the sector model can’t be applied where the sector would be a service sector without having a well developed secondary sector (Kenya tourism) The model doesn’t take account to the international economic context & not showing the import of manufactured
