The future of the economy is in the service sector. — Peter Drucker
6.1 Tertiary Activities
Tertiary activities provide services rather than goods. They do not produce tangible products but facilitate production, exchange, and daily life.
Major types:
- Trade — wholesale and retail
- Transport — moving people and goods
- Communication — transmitting information
- Finance — banking, insurance, stock markets
- Personal services — healthcare, education, hospitality, entertainment
The tertiary sector dominates employment in most developed economies.
6.2 Quaternary and Quinary Activities
- Quaternary — knowledge-based services: research, data analysis, IT, media, consultancy
- Quinary — top-level decision-making: government leaders, corporate executives, scientists
These sectors cluster in world cities (London, New York, Tokyo) with advanced infrastructure and skilled labour.
6.3 Some Key Tertiary Sectors
Retail:
- Traditional markets → supermarkets → e-commerce
- CBD (Central Business District) — high land values, offices, shops
Tourism:
- Fastest-growing tertiary activity globally
- Types: cultural, eco, adventure, medical, business
- Impacts: income and jobs vs. environmental degradation and cultural commodification
Medical services:
- Hospitals, clinics, telemedicine
- Medical tourism — patients travel for affordable or specialised care (India, Thailand)
