The sectors of the economy refer to different categories or divisions that classify economic activities based on the type of goods or services produced. Each sector plays a distinct role in the overall functioning of the economy, and understanding them helps in analyzing economic trends, making policy decisions, and assessing the structure of an economy.
The traditional classification includes three main sectors:
Primary sector
This sector involves activities related to natural resources and raw materials extraction. It includes industries such as agriculture, forestry, fishing, mining, and extraction of minerals and fuels. The primary sector is typically characterized by direct interaction with the environment and natural resources.

Secondary sector
Also known as the manufacturing sector, the secondary sector involves the processing of raw materials obtained from the primary sector into finished goods. Activities in this sector include manufacturing, construction, and utilities (such as electricity, gas, and water supply). The secondary sector adds value to raw materials through processing and manufacturing processes.
Tertiary sector
The tertiary sector, also known as the service sector, encompasses activities that provide services rather than tangible goods. This sector includes a wide range of industries such as retail, healthcare, education, finance, transportation, tourism, hospitality, and professional services like legal and consulting services. The tertiary sector is characterized by intangible outputs and a focus on providing services to consumers and businesses.
In addition to these traditional sectors, some classifications may include a quaternary sector, which involves intellectual activities such as information technology, research and development, and information services. Similarly, a quinary sector may be included, representing high-level decision-making and executive functions in organizations, as well as activities related to culture, arts, and media. These classifications may vary depending on the context and the specific model used for analysis.
