Describe the working setting and conditions in each of the four economic sectors​

Primary activities:Primary activities are directly dependent on the environment as these refer to utilisation of earth’s resources such as land, water, vegetation, building materials and minerals. It, thus includes hunting and gathering, pastoral activities, fishing, forestry, agriculture, and mining and quarrying.

Secondary activities:Secondary activities add value to natural resources by transforming raw materials into valuable products. Secondary activities, therefore, are concerned with manufacturing, processing and construction (infrastructure) industries.

Tertiary activities:Tertiary activities include both production and exchange. The production involves the ‘provision’ of services that are ‘consumed. Exchange involves trade, transport and communication facilities that are used to overcome distance.

Quaternary activities:Quaternary activities are specialized tertiary activities in the ‘Knowledge Sector’ which demands a separate classification. There has been a very high growth in demand for and consumption of information-based services from mutual fund managers to tax consultants, software developers and statisticians. Personnel working in office buildings, elementary schools and university classrooms, hospitals and doctors’ offices, theatres, accounting and brokerage firms all belong to this category of services. Like some of the tertiary functions, quaternary activities can also be outsourced. They are not tied to resources, affected by the environment, or necessarily localised by market.
