The Development Gap

The development gap refers to the growing difference in levels of development between the world's richest and poorest countries. In this lesson you will explore the causes of inequality between countries, why some countries remain trapped in poverty, and the physical, economic, and historical factors that create and maintain the development gap.

What Is the Development Gap?

The development gap is the difference in wealth, health, and quality of life between the most developed countries (HICs) and the least developed countries (LICs). This gap exists at multiple scales:

• Global scale — between rich nations (e.g., UK, USA) and poor nations (e.g., Chad, Malawi)
• Regional scale — between regions within a country (e.g., south-east England vs north-east England)
• Local scale — between neighbourhoods within a city (e.g., wealthy suburbs vs inner-city deprivation)

Exam Tip: AQA may ask you to explain the development gap at different scales. Always be ready to give examples at the global, national, and local level.

Causes of the Development Gap

The development gap is caused by a combination of physical, economic, historical, and political factors. These factors often interact with each other, creating a cycle that is difficult to break.

Physical Factors

Factor	How It Affects Development	Example
Climate	Extreme climates (very hot, very dry, or prone to monsoons) make farming difficult and reduce productivity	Countries in the Sahel region of Africa face frequent droughts that destroy harvests
Landlocked location	Countries without a coastline struggle to trade because transport costs are higher	Chad and Niger are landlocked and have some of the lowest HDI scores in the world
Natural hazards	Earthquakes, volcanic eruptions, floods, and tropical storms destroy infrastructure and divert funds from development	Haiti was devastated by a 7.0 magnitude earthquake in 2010 and has struggled to recover
Limited natural resources	Countries without valuable resources (oil, minerals, fertile land) have fewer exports to generate wealth	Some small island developing states have very limited natural resources

Economic Factors

Factor	How It Affects Development	Example
Trade disadvantages	Many LICs export cheap raw materials and import expensive manufactured goods — the terms of trade are unfair	Ghana exports raw cocoa beans at low prices but imports expensive chocolate made in Europe
Debt	Many LICs borrowed heavily in the 1970s and 1980s and are still repaying loans with high interest, diverting money from healthcare and education	Sub-Saharan African countries owed over $300 billion in debt by 2000
Dependence on primary products	Economies reliant on one or two commodities are vulnerable to price fluctuations on world markets	Zambia's economy depends heavily on copper — when copper prices fall, the whole economy suffers
Lack of investment	Without stable infrastructure and governance, foreign companies are reluctant to invest	Many LICs lack reliable electricity, roads, and internet, making them unattractive to investors

Historical Factors

Factor	How It Affects Development	Example
Colonialism	European powers exploited resources and labour in Africa, Asia, and South America for centuries, leaving these regions underdeveloped	Britain, France, Belgium, and Portugal colonised most of Africa and extracted wealth for their own economies
Slave trade	Millions of people were forcibly removed from Africa over 400 years, destroying communities and economies	West Africa lost an estimated 12 million people to the transatlantic slave trade
Artificial borders	Colonial powers drew borders that ignored ethnic and cultural boundaries, leading to conflict	Nigeria's borders (drawn by the British) contain over 250 ethnic groups, contributing to internal tensions

Political Factors

Factor	How It Affects Development
Corruption	Government officials divert aid money and tax revenue into personal accounts rather than spending it on services
Conflict and war	Civil wars destroy infrastructure, displace populations, and divert spending to military purposes
Poor governance	Weak institutions, lack of rule of law, and unstable governments deter investment and prevent long-term planning

Exam Tip: In a 9-mark question about causes of the development gap, aim for three well-developed points from different categories (e.g., one physical, one economic, one historical). Always include specific examples and explain the chain of reasoning.

The Demographic Transition Model (DTM)

The Demographic Transition Model shows how a country's population structure changes as it develops. It has five stages:

Stage	Birth Rate	Death Rate	Population Growth	Example Countries
1	High	High	Stable (low)	No countries today (pre-industrial societies)
2	High	Falling	Rapid growth	Afghanistan, some sub-Saharan African nations
3	Falling	Low	Slowing growth	Nigeria, India, Brazil
4	Low	Low	Stable (high)	UK, France, USA
5	Very low	Low	Declining	Japan, Germany, Italy

Why Does the DTM Matter for Development?

• Countries in Stage 2 have a very young population, meaning a high dependency ratio — many children to feed and educate, but few working-age adults earning income.
• Countries in Stage 4 have a more balanced population and can invest in services and infrastructure.
• Countries in Stage 5 face the challenge of an ageing population — fewer workers supporting more retirees.

Uneven Development Within Countries

Development is never evenly spread within a country. Even in HICs, there are significant regional differences.

The UK Example

Region	Average Income	Life Expectancy	Key Characteristics
London and South-East	Highest in the UK	Higher	Financial services, government, technology, tourism
North-East England	Among the lowest	Lower	Post-industrial decline, former coalfields and steelworks, higher unemployment

Why Does Uneven Development Occur Within Countries?

1. Historical investment — some regions received more infrastructure investment than others
2. Deindustrialisation — the decline of manufacturing hit certain regions harder (e.g., the Midlands and North of England)
3. Government spending — capital cities often receive more investment
4. Transport links — areas with better connections attract more businesses
5. Migration — young, skilled workers move to prosperous areas, leaving declining regions with an older population

Consequences of the Development Gap

For LICs

• Poor health outcomes — higher infant mortality, lower life expectancy, greater vulnerability to disease
• Limited education — fewer schools, fewer trained teachers, lower literacy rates
• Brain drain — educated professionals emigrate to HICs, depriving LICs of skilled workers
• Environmental degradation — poverty drives deforestation and overuse of land
• Political instability — inequality can fuel resentment and conflict

For HICs

• Migration pressures — people from LICs seek better opportunities in HICs
• Global health risks — diseases that thrive in LICs can spread globally
• Economic instability — poverty in LICs reduces the size of global markets
• Moral responsibility — HICs face pressure to provide aid and support development

The Cycle of Poverty

Many LICs are trapped in a cycle of poverty (also called a poverty trap):

1. Low incomes mean people cannot save or invest
2. Without investment, there are few jobs and poor services
3. Poor health and education reduce productivity
4. Low productivity keeps incomes low
5. The cycle repeats
