The secondary sector refers to the part of the economy that focuses on the processing of raw materials into finished products. This sector turns raw resources from nature into goods that people can use.

It includes activities such as:

• Manufacturing of goods
• Construction
• Mining and quarrying
• The production of utilities like electricity and water supply

Key features of this sector include:

• It involves the physical transformation of materials into usable products.
• It creates tangible goods, which is different from providing services.
• It often offers higher wages compared to the primary sector (like farming).
• It is essential for industrial development and economic growth.
• Countries that rely heavily on this sector are often called industrializing economies.
