1. ECONOMIC ACTIVITY

2. Economic Activity - Key Ideas
Activities contributing to the economy of a country are divided into 3 sectors:
PRIMARY
SECONDARY
TERTIARY
Extractive
Manufacturing
Services
Data usually shows the % of a country’s workforce that is employed in each of the sectors. This is known as the EMPLOYMENT STRUCTURE of a country

3. Employment structure data is often used as a development indicator because it shows clear differences between MEDCs and LEDCs
“Typical” LEDC = ??
Dominated by primary employment
eg Burkina Faso P = 87% S = 5% T = 8%
“Typical” MEDC = ??
Mainly tertiary employment
eg France P = 5% S = 20% T = 75%
4. As countries develop, their employment structures change
eg Egypt in P = 71% S = 10% T = 19%
Egypt in P = 42% S = 21% T = 37%

4. LEDCs developing today do not necessarily follow the same route through the sectors as current MEDCs did when they developed
Eg the ‘Asian Tiger’ NICs* of the Pacific Rim
(eg South Korea, Taiwan, Malaysia etc)
* = ?
Newly Industrialised Countries
Secondary sector often less significant in employment terms, but wrong to say that there is no mnfg~ in NICs
Reasons? Technological innovation, expansion of world trade
6. Sectoral change leaves problems in its wake
eg the decline of coal mining in the UK
eg deindustrialisation in MEDCs (manufacturing decline)
eg the role of multinational corporations in LEDCs
