An industry is a group of businesses that produce or supply goods, services, or sources of income. In economics, industries are generally classified as primary, secondary, tertiary, and quaternary.
- Primary industries extract or produce raw materials from which useful items can be made. Examples include mining, agriculture, and fishing.
- Secondary industries change raw materials into usable products through processing and manufacturing. Examples include the automotive industry, the food processing industry, and the electronics industry.
- Tertiary industries provide services to businesses and individuals. Examples include the retail industry, the healthcare industry, and the hospitality industry.
- Quaternary industries provide knowledge-intensive services, such as research and development, education, and financial services.
Industries can also be classified by their size, such as small-scale and large-scale. Small-scale industries are typically characterized by low capital investment and a small number of employees. Large-scale industries, on the other hand, are characterized by high capital investment and a large number of employees.
Industries are important to the economy because they produce the goods and services that people need and want. They also create jobs and provide a source of income for individuals and families.
