An industry is a specific branch of an economy composed of a group of companies or organizations that engage in similar primary business activities, share standard production methods, and offer closely related goods or services.
Economists and classification systems, such as the Global Industry Classification Standard (GICS) or the North American Industry Classification System (NAICS), formally group economic production into four distinct chronological levels: 1. Primary Industry (Extraction)
Definition: Businesses that harvest, collect, or extract natural raw materials directly from the Earth or sea.
Core Activities: Agriculture, commercial fishing, forestry, oil extraction, and mining.
Economic Role: Forms the foundational resource layer for developing nations and serves as the physical backbone for global supply chains. 2. Secondary Industry (Manufacturing)
Definition: Enterprises that take raw inputs from primary industries and process or assemble them into consumer-ready finished goods.
Core Activities: Automotive manufacturing, electronics assembly, textile production, food processing, and heavy construction.
Economic Role: Drives industrialization, factory employment, and physical technology infrastructure. 3. Tertiary Industry (Services)
Definition: Companies that provide intangible actions, customer support, or commercial services rather than physical goods.
Core Activities: Healthcare, retail sales, commercial banking, hospitality, transportation, and public education.
Economic Role: Represents the largest job creation sector, accounting for over 1.6 billion jobs globally in modern developed economies. 4. Quaternary Industry (Knowledge & Innovation) Britannica Industry | Definition, Sectors, & Facts | Britannica Money
