Poverty and Inequality

Have you ever wondered why some people can buy clean water, reliable internet, and a safe home while others struggle to afford food, school fees, or medicine? 🌍 In IB Global Politics HL, poverty and inequality are central ideas in the study of development and sustainability because they show how resources, opportunities, and power are distributed within and between societies. In this lesson, students, you will learn the main terms, how to analyze poverty and inequality using global politics thinking, and how these issues connect to development strategies and sustainability goals.

What do poverty and inequality mean?

Poverty usually means not having enough resources to meet basic human needs. These needs include food, clean water, shelter, healthcare, education, and safety. Poverty is not only about low income. A person can earn some money but still be poor if that income is not enough to live with dignity.

There are two common ways to measure poverty:

Absolute poverty refers to living below a fixed minimum standard needed for survival and basic life. The World Bank uses an international poverty line to compare extreme poverty across countries.
Relative poverty refers to being poor compared with the average standard of living in a society. A person may have enough to survive but still be excluded from normal social life, such as joining school trips, buying devices for class, or participating in community events.

Inequality means unequal distribution of wealth, income, power, opportunities, or social status. Inequality can exist between individuals, groups, regions, or countries. It is important to remember that poverty and inequality are related but not the same. A country can have low poverty but still high inequality, or lower inequality but still widespread poverty.

A useful way to think about this is simple: poverty asks, “How many people lack basic needs?” while inequality asks, “How unevenly are resources and opportunities shared?” 🤔

How global politics helps explain poverty and inequality

Global politics looks at how power works in the world. Poverty and inequality are not only economic problems; they are also political because governments, international organizations, businesses, and social movements all influence who gets what.

For example, public policy can affect poverty through:

taxation and welfare systems
access to free or affordable healthcare
quality public education
minimum wage laws
housing policy
infrastructure such as roads, electricity, and internet

International factors also matter. Trade rules, debt, foreign investment, aid, conflict, and climate change can all shape development outcomes. Some countries grow richer because they control technology, capital, and trade networks, while others remain dependent on exporting low-value raw materials. This can create global inequalities between the Global North and Global South.

IB Global Politics HL expects students to think critically about power. For poverty and inequality, this means asking:

Who has access to decision-making?
Who benefits from economic growth?
Who is left out of development?
How do institutions shape outcomes?

This reasoning is important because inequality is often not accidental. It is linked to laws, institutions, and historical patterns such as colonialism, discrimination, and unequal trade relationships.

Measuring poverty and inequality

To study poverty and inequality well, students, you need evidence. Global politics uses indicators to compare countries and track change over time 📊

Poverty indicators

One common measure is the multidimensional poverty index, which looks beyond income and includes education, health, and living standards. This is useful because poverty is complex. Someone may have money but still lack clean water or schooling.

Other indicators include:

income per person
access to healthcare
school enrollment and literacy
infant mortality rates
access to electricity, sanitation, and safe housing

Inequality indicators

A common measure of income inequality is the Gini coefficient. It ranges from $0$ to $1$ or sometimes from $0$ to $100$ depending on the reporting system. A value of $0$ means perfect equality, while a higher value means greater inequality.

However, the Gini coefficient does not show everything. Two countries may have the same Gini score but very different realities. One may have strong public services, while another may have poor services and deep social divisions. That is why IB students should use multiple indicators, not just one.

A strong exam answer often combines data with explanation. For example, a country may have a high GDP per capita but still experience poverty among rural communities if wealth is concentrated in cities or among elites. This shows that development is not only about total national wealth; it is also about who benefits from it.

Causes of poverty and inequality

Poverty and inequality have many causes, and these causes often work together.

Economic causes

unemployment or informal employment
low wages
unequal access to land, credit, and markets
weak infrastructure
dependence on unstable exports

If a country depends heavily on one commodity, such as oil or cocoa, prices on the world market can rise and fall sharply. This can create instability and make long-term development harder.

Political causes

corruption
weak institutions
conflict and war
discrimination in law or practice
poor public spending

If public money is diverted by corruption, fewer resources remain for schools, hospitals, and roads. This can trap communities in poverty.

Social causes

gender inequality
ethnic or racial discrimination
unequal access to education
social exclusion of migrants, refugees, or minority groups

For example, girls may be less likely to attend school in areas where families believe boys should receive priority. Over time, that can limit income, political participation, and social mobility.

Historical causes

colonial rule and extraction of resources
slavery and forced labor systems
unequal borders and state formation
long-term underdevelopment in former colonies

These historical processes matter because they shaped economic structures that still affect countries today. Global inequalities often reflect the past as well as the present.

Development strategies and trade-offs

Governments and international organizations use different strategies to reduce poverty and inequality. But every strategy involves trade-offs.

Economic growth strategy

Some governments focus on rapid economic growth through industrialization, foreign investment, and trade. Growth can create jobs and increase tax revenue. However, if the gains go mostly to elites, inequality may rise even while the economy expands.

Redistribution strategy

Other governments use taxes and welfare to share wealth more fairly. Policies like cash transfers, subsidized food, free education, or public healthcare can reduce poverty quickly. The trade-off is that these programs require public revenue and strong administration.

Human development strategy

This approach focuses on people’s capabilities, not just income. It emphasizes education, health, gender equality, and political participation. This approach is linked to the idea that development should improve people’s real freedoms, not only national wealth.

Sustainable development strategy

Sustainable development means meeting present needs without harming the ability of future generations to meet theirs. This links poverty reduction with environmental protection. For example, building jobs in renewable energy can reduce poverty while also lowering carbon emissions.

Trade-offs appear when policies help one goal but harm another. A dam may provide electricity and support industry, but it may also displace communities and damage ecosystems. A mining project may create jobs but pollute water and deepen local inequality if profits leave the area. ⚖️

Inequality, sustainability, and global institutions

Poverty and inequality are not separate from sustainability; they are part of it. If large groups of people lack access to food, housing, and healthcare, it becomes harder to achieve long-term social stability. Environmental damage also affects poor communities first and hardest, because they often have fewer resources to adapt.

Global institutions play an important role in addressing these issues:

The United Nations promotes global development goals and human rights.
The World Bank provides loans and development advice.
The International Monetary Fund supports financial stability, but its policies may be criticized if they encourage spending cuts that affect social services.
Non-governmental organizations and local civil society groups often support education, health, and community development.

The Sustainable Development Goals are especially relevant. Goal $1$ aims to end poverty, and Goal $10$ aims to reduce inequality. These goals show that poverty reduction and equality are global priorities, not just national ones.

In IB Global Politics HL, it is important to evaluate institutions critically. Ask whether they reduce inequality, or whether they sometimes reinforce it through conditions, power imbalances, or unequal influence from richer states.

Conclusion

Poverty and inequality are key themes in Development and Sustainability because they reveal how resources, rights, and opportunities are shared. Poverty focuses on deprivation, while inequality focuses on uneven distribution. Both are shaped by economic systems, political decisions, social structures, and historical legacies. To analyze these issues well, students, use evidence, compare perspectives, and think about trade-offs between growth, redistribution, and sustainability. A strong global politics analysis does not stop at describing poverty; it asks why it exists, who is affected, and how power can be used to reduce it in fair and sustainable ways 🌱

Study Notes
