The following changes occur as a country becomes more developed: Primary activities decrease:
- As the country gets richer, it can rely less on its own natural resources and start importing from other countries
- Importing products means the country can get a wider range of products at a cheaper price.
Secondary activities increase and then decrease:
- It increases as country makes more products but then the country starts importing "ready made products" so less people are needed in the secondary industry.
- Machines also take over secondary employment when countries get rich enough to buy them.
Tertiary activities increase:
- Machines have taken over employment in other areas so people must seek work in tertiary.
- As the country improves its health and education service, more jobs are needed.
