Mastering Changing economies: IGCSE Geography Study Notes

Have you ever wondered why your trainers were designed in one country, made in another, and sold in yours?

That question sits right at the heart of Changing economies, one of the most exam-relevant topics in your Cambridge IGCSE Geography (0460) course. The way countries earn money, the jobs people do, and the industries that thrive are all shifting constantly. Understanding why they shift - and what that means for real communities - is exactly what examiners want to see in your answers.

This topic breaks into three big areas: changing employment structures, globalisation and transnational corporations (TNCs), and tourism. Each one connects to the others, and the exam loves to test those connections. Your job is to learn the content, spot the links, and apply them confidently under timed conditions.

Changing Employment Structures

The Four Sectors of Industry

Before you can analyse how employment is changing, you need to be completely comfortable with the four sectors of industry. These come up on almost every IGCSE Geography paper that covers this topic, and the Cambridge IGCSE 0460 syllabus expects you to classify any example confidently.

How Employment Structures Differ Between LICs, MICs, and HICs

The proportion of workers in each sector tells you a great deal about a country's level of economic development. This is a favourite exam question, so make sure you can describe and explain the pattern.

Low-Income Countries (LICs) have a large percentage of workers in the primary sector. Subsistence farming dominates because mechanisation is limited, infrastructure is basic, and there are fewer opportunities in manufacturing or services. A typical breakdown might be 60-70% primary, 10-15% secondary, and 20-25% tertiary.

Middle-Income Countries (MICs) show a growing secondary sector. As countries industrialise, factories open, people migrate from rural areas to cities for manufacturing jobs, and the primary sector shrinks as a share of total employment. The tertiary sector also grows as rising incomes create demand for services like healthcare, education, and retail.

High-Income Countries (HICs) have most workers in the tertiary and quaternary sectors. Manufacturing has often declined (a process called deindustrialisation), sometimes because production has moved to countries with cheaper labour. Primary employment is very low because agriculture is heavily mechanised. A typical HIC might have just 2-5% in primary, 15-20% in secondary, and 70-80% in tertiary and quaternary combined.

Factors Influencing the Location and Distribution of Economic Activities

Why do factories spring up in some places and not others? Why do call centres cluster in certain cities? The syllabus lists several key location factors, and you should be able to explain how each one pulls economic activity towards a particular place.

• Land - Flat, cheap land attracts large factories and warehouses. City-centre land is expensive, pushing heavy industry to the edges or overseas.
• Labour - Industries need workers with the right skills and at the right cost. Garment factories locate where labour is plentiful and wages are lower. Tech firms cluster near universities that produce skilled graduates.
• Raw materials - Heavy or bulky raw materials pull industries towards the source. Steel works historically sat near coalfields and iron ore deposits to reduce transport costs.
• Energy supply - Reliable, affordable energy is essential for manufacturing. Aluminium smelting, for example, uses enormous amounts of electricity and tends to locate near hydroelectric power sources.
• Transport and communications - Good road, rail, port, and airport connections reduce costs and delivery times. Businesses cluster along motorway corridors and near container ports.
• Markets - Some industries locate close to their customers. Bakeries, newspapers, and fresh food processors benefit from being near the people who buy their products.
• Government policies - Tax incentives, enterprise zones, trade agreements, and planning regulations all influence where businesses choose to set up. Governments in MICs often create special economic zones (SEZs) to attract foreign investment.
• Technology - Advances in automation, robotics, and digital communication mean some industries no longer need to be near raw materials or large labour pools. This has enabled the rise of home working and offshore service centres.
• Containerisation - The development of standard shipping containers revolutionised global trade. It slashed the cost and time of moving goods internationally, making it economically viable to manufacture products on one continent and sell them on another.

Globalisation and Transnational Corporations

What Is Globalisation?

Globalisation is the process by which the world's economies, cultures, and populations are becoming increasingly interconnected. It means goods, services, money, ideas, and people flow more freely across national borders than ever before.

Think about your daily life for a moment. Your phone was probably designed in the United States, assembled in China using minerals mined in the Democratic Republic of Congo, and shipped to your country in a container. You might stream music from a Swedish company, watch films from South Korea, and wear clothes stitched in Bangladesh. That web of connections is globalisation in action.

Key Features of Globalisation

• Growth of international trade and investment
• Expansion of transnational corporations operating across multiple countries
• Improvements in transport (containerisation, larger cargo ships, cheaper air freight)
• Advances in communication technology (internet, mobile phones, video conferencing)
• Greater movement of people between countries for work, study, and tourism
• Spread of cultural products, brands, and ideas across borders

The Role of Transnational Corporations (TNCs)

A transnational corporation is a company that operates in more than one country. The headquarters are usually in a HIC, while production, assembly, or service operations are spread across MICs and LICs where costs are lower.

Major TNCs you might reference in your exam include companies like Nike, Apple, Toyota, Unilever, and Samsung. These firms have complex supply chains spanning dozens of countries.

Advantages and Disadvantages of TNCs for Host Countries

This is one of the most commonly examined areas within the IGCSE Geography globalisation sub-topic. You need to be able to argue both sides clearly.

The Impact of Globalisation on Different Countries

Globalisation does not affect every country equally. HICs tend to benefit from controlling the high-value stages of production (design, marketing, finance) while LICs and MICs often supply cheap labour and raw materials.

Some MICs - particularly China, India, Vietnam, and Bangladesh - have experienced rapid economic growth through integration into global supply chains. Factory employment has lifted millions out of poverty. But the gains come with trade-offs: poor working conditions, environmental pollution, and vulnerability to shifts in global demand.

LICs sometimes find it harder to benefit. They may lack the infrastructure, education systems, or political stability needed to attract TNCs. When TNCs do arrive, the benefits can be concentrated in a few urban areas while rural communities see little change.

Tourism: A Growing Global Industry

Why Is Tourism Growing?

Tourism is one of the fastest-growing industries in the world. Your IGCSE Geography course expects you to know why, and examiners test this frequently. Several factors have driven this growth:

• Rising incomes - As people in HICs and MICs earn more disposable income, they spend more on holidays and travel.
• Cheaper air travel - Budget airlines and increased competition have made flying affordable for millions more people.
• More leisure time - Paid holidays, shorter working weeks, and earlier retirement give people more time to travel.
• Improved transport links - Motorways, high-speed rail, and expanded airports make destinations more accessible.
• Marketing and media - Social media, travel websites, and TV programmes inspire people to visit new places.
• Package holidays - Tour operators bundle flights, accommodation, and activities into affordable packages, making international travel simpler.
• Greater awareness of destinations - The internet allows people to research, compare, and book trips to places they might never have considered before.

Benefits and Disadvantages of Tourism

The exam often asks you to evaluate tourism's impact on a named area or on a country more broadly. You need to cover economic, social, and environmental effects.

Economic Effects

Social Effects

Benefits: Tourism can preserve cultural traditions and heritage sites because they become attractions worth maintaining. It promotes cross-cultural understanding and can fund community facilities like schools or clinics.

Disadvantages: Large numbers of tourists can erode local culture, replacing traditional ways of life with commercialised versions. Overcrowding causes resentment among residents. Increased crime, noise, and antisocial behaviour can follow tourist development.

Environmental Effects

Benefits: Revenue from tourism can fund conservation projects and protect natural areas. National parks and nature reserves may receive more investment because of their value as tourist attractions.

Disadvantages: Tourism generates pollution (air travel emissions, vehicle exhaust, waste). Fragile ecosystems like coral reefs, sand dunes, and mountain trails suffer from visitor pressure. Hotel and resort construction can destroy habitats and increase water consumption in areas where water is already scarce.

Sustainable Tourism and Ecotourism

Sustainable tourism is a concept that appears regularly on IGCSE Geography papers. It aims to meet the needs of present tourists and host communities while protecting opportunities for future generations. It balances economic growth with environmental protection and social responsibility.

Ecotourism is a specific type of sustainable tourism focused on visiting natural areas in a way that conserves the environment and benefits local people. Key features include:

• Small group sizes to minimise environmental impact
• Use of local guides, accommodation, and food so that money stays in the community
• Education for visitors about the local ecosystem and culture
• Active conservation efforts funded by tourism revenue
• Minimal disturbance to wildlife and habitats

A strong exam example is Costa Rica, where ecotourism in rainforest reserves generates income for local communities while protecting biodiversity. Visitors stay in small eco-lodges, hire local guides, and pay park fees that fund conservation. The model works because the community has a direct financial stake in protecting the environment.

Worked Example: Evaluating a TNC's Impact

Here is the kind of extended-response question you should expect on your IGCSE Geography paper.

Question: Evaluate the advantages and disadvantages of a transnational corporation locating a factory in a low-income country. [6 marks]

Model Answer:

A TNC locating a factory in a LIC creates employment opportunities for local people who may previously have relied on subsistence farming, raising household incomes and reducing poverty (1 mark). The investment brings new technology and training, improving the skill levels of the workforce (1 mark). Tax revenue from the TNC can be used by the government to fund public services such as schools and hospitals (1 mark).

However, wages in TNC factories are often very low compared to those in the company's home country, and working conditions may be poor (1 mark). Much of the profit is repatriated to the TNC's headquarters rather than being reinvested locally (1 mark). The host country may also suffer environmental damage, such as water pollution or deforestation, because environmental regulations are weaker than in the TNC's home country (1 mark).

Common Mistakes to Avoid

These are the errors that cost students marks year after year:

1. Confusing the four sectors. Quaternary is not the same as tertiary. If a question mentions research and development, that is quaternary. If it mentions a shop or a hospital, that is tertiary. Learn the distinction.
2. Being vague about TNCs. Don't just write "TNCs bring jobs." Specify the type of jobs, the wages, the conditions, and whether local people benefit long-term. The mark scheme rewards detail.
3. Forgetting economic leakage. Many students describe tourism's benefits without ever mentioning that profits often leave the country through foreign-owned hotels and airlines. Examiners look for this balance.
4. Treating globalisation as entirely positive or entirely negative. The strongest answers show both sides and offer a balanced judgement. One-sided answers cap your marks.
5. Ignoring case study detail. Generic answers score lower than those that reference real places, companies, or data. Even a brief mention of a named TNC or tourism destination shows the examiner you have applied your knowledge.
6. Writing about tourism impacts without categorising them. Always separate economic, social, and environmental effects. Mixing them together makes your answer muddled and harder to mark.

Self-Check Questions

Test yourself with these before you move on. Try to answer each one in two or three sentences, then check your understanding against the notes above.

1. Name and define the four sectors of industry.
2. Describe the typical employment structure of a low-income country and explain why the primary sector dominates.
3. List three factors that influence where a factory might locate and explain how each one matters.
4. What is globalisation? Give two examples of how it affects your daily life.
5. Explain two advantages and two disadvantages of a TNC setting up operations in a middle-income country.
6. Why has international tourism grown so rapidly in recent decades? Name at least three reasons.
7. What is the difference between sustainable tourism and ecotourism?
8. Describe one economic, one social, and one environmental disadvantage of tourism for a host community.

Bringing It All Together

Changing economies is a topic where everything connects. Globalisation drives the growth of TNCs, which shift manufacturing from HICs to LICs and MICs, which changes employment structures. Tourism grows because of the same forces - cheaper transport, better communications, rising incomes - and creates both opportunities and challenges for host countries.

When you revise, practice drawing these links. If a question asks about employment change in a named country, think about how globalisation and TNCs contributed. If a question asks about tourism in a LIC, think about economic leakage and whether the jobs created are sustainable. The students who score highest on IGCSE Geography are those who connect ideas across sub-topics rather than treating each section in isolation.

Your strongest answers will name real places, give specific figures where you can, and present a balanced argument. Go back through the self-check questions and make sure you can answer every one confidently. If any of them gave you difficulty, re-read that section carefully. This is a topic where understanding the patterns matters more than memorising lists.
