2. Historical Evolution of Sectors
- Agrarian Stage: Initially, primary sector is the supreme producer and largest employer.
- Industrial Stage: Mechanization shifts surplus labor into factories; secondary sector emerges as dominant (18th-19th Century).
- Service Stage: In developed nations over the last century, service/tertiary sector expands to generate the bulk of GDP and employment.
3. Why has the Tertiary Sector Grown Rapidly in India?

- Agricultural & Industrial Linkage: Expansion of farms and factories creates immense demand for logistics, warehouses, and trade.
