Sectors of Business Activity and Sectoral Change
- Let's consider a country that once relied heavily on agriculture.
- Over time, it invests in manufacturing, then shifts to a service-based economy.
This transformation is called sectoral change.
The Four Sectors of Business Activity
Primary Sector: Extracting Raw Materials
Primary sector
The primary sector involves acquiring natural resources.
- Agriculture: Growing crops and raising livestock for food, raw materials, or other products.
- Fishing: Harvesting fish and other seafood from oceans, rivers, and lakes.
- Forestry: Managing and harvesting trees for timber, paper, and other products.
- Mining: Extracting minerals, metals, and fossil fuels from the ground.
A wheat farm cultivates crops that are later processed into flour for bread and other food products.

The secondary sector focuses on transforming raw materials into finished products.
- Manufacturing: Producing goods like cars, electronics, or clothing.
