An industry sector is a broad category of economic activity. These sectors are used to classify companies and businesses based on the primary type of product or service they offer. The most common high-level categorization divides the economy into three primary sectors: primary, secondary, and tertiary.

The primary sector involves the extraction and production of raw materials. This includes agriculture, mining, forestry, and fishing. These industries are fundamental as they provide the basic resources for other economic activities.

The secondary sector, often called the manufacturing or industrial sector, involves the transformation of raw materials into finished goods. This encompasses construction, manufacturing of durable and non-durable goods, and utilities like electricity and gas.

The tertiary sector, also known as the service sector, involves providing services rather than tangible products. This is the largest sector in many developed economies and includes a wide range of activities such as retail, transportation, healthcare, education, finance, hospitality, and information technology.

More detailed classifications exist, often referred to as industry sector classifications or industry codes. These systems, like the North American Industry Classification System (NAICS) or the Standard Industrial Classification (SIC), break down the economy into progressively more specific sub-sectors and industries, allowing for more granular analysis of economic trends and performance. Understanding these sectors is crucial for economic analysis, policy-making, and investment.
