How is wealth and wellbeing distributed across and within countries, what causes these patterns of inequality, and how can they be reduced?
Describe global patterns of inequality, explain their causes, analyse their consequences, and evaluate strategies that aim to reduce inequality between and within places.
How development and wellbeing are measured and distributed, why inequality exists between and within countries, its consequences, and the strategies used to reduce it, illustrated with Australian and global cases.

What this dot point is asking
This dot point sits in Topic 2, Social and Economic Change. The geographical skill at its centre is measuring and mapping development. Strong answers use the right indicators, recognise that inequality exists both between countries and within them, and judge how effective different strategies are.
Measuring and mapping inequality
Development is more than money, so geographers use composite indicators.
- Gross National Income per person measures average wealth but hides how it is shared.
- The Human Development Index combines income, life expectancy and education into a score from 0 to 1, ranking countries from very high to low human development.
- The Gini coefficient measures inequality within a country, where 0 is perfect equality and 1 is maximum inequality.
These reveal a broad pattern of a wealthier Global North and a poorer Global South, but also wide gaps within rich countries. In Australia, a clear development gap exists between Indigenous and non-Indigenous Australians, which the Closing the Gap framework targets.
Causes of inequality
Patterns of inequality have layered causes:
- Historical, including colonialism that extracted resources and drew borders that still shape economies today.
- Economic, including dependence on a few low-value commodity exports, debt, and unequal terms of trade.
- Political and social, including corruption, conflict, weak institutions and unequal access to education and health, especially for women and girls.
- Physical, including landlocked location, drought-prone climates and disease burdens that hold back development.
Consequences across systems
Economically, deep inequality slows national growth because large parts of the population cannot invest in education, health or business. Socially, it drives poorer health, lower life expectancy and higher rates of conflict and migration. Within wealthy countries, unequal access to services entrenches disadvantage across generations, as seen in differences in life expectancy between richer and poorer suburbs of Australian cities. Environmentally, poverty can force overuse of fragile land, while wealth drives high-consumption emissions.
Strategies to reduce inequality
Strategies operate at international and national scales.
- Aid: official development assistance funds health, education and infrastructure. It can save lives and build capacity but risks dependency and may be poorly targeted.
- Trade and fair trade: fairer access to markets and Fairtrade premiums can raise producer incomes, though they reach only some farmers.
- Debt relief: cancelling unpayable debt frees money for services, but works only alongside good governance.
- The Sustainable Development Goals: 17 global goals to 2030 set shared targets on poverty, health, education and equality, providing a framework even if progress is uneven.
- National policy: in Australia, Closing the Gap sets targets to reduce disparities in Indigenous health, education and employment, with mixed progress.
Linking it together
A complete response measures inequality with the right indicators, describes patterns between and within countries, explains historical, economic and political causes, analyses consequences across systems, and evaluates strategies from aid to the Sustainable Development Goals and Closing the Gap. That structure matches the geographical skills and applications criteria the SACE Board assesses.
Exam-style practice questions
Practice questions written in the style of SACE Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
SACE 20215 marksUsing the supplied development indicators, describe the global pattern of inequality and explain two causes of the differences shown.Show worked answer →
A 5 mark source-and-explain response needs an accurate pattern from the data, then two causes.
Describe the pattern. Read the indicators (for example Human Development Index or income per person) to show a wealthier Global North and a poorer Global South, quoting figures and noting outliers.
Explain two causes. Develop two from the historical (colonialism), economic (commodity dependence, debt, unequal terms of trade), political (corruption, conflict, weak institutions) or physical (landlocked, disease) factors.
Markers reward exact use of the indicators, a clear North-South pattern with outliers, and two developed causes rather than a long list.
SACE 20238 marksAnalyse the consequences of inequality both between and within countries, and evaluate the effectiveness of strategies used to reduce it.Show worked answer →
An 8 mark response needs consequences at both scales, then a judgement on strategies.
Analyse consequences. Between countries, explain how commodity dependence and debt slow development; within countries, explain entrenched disadvantage such as the Indigenous and non-Indigenous gap in Australia and suburb-level life-expectancy differences.
Evaluate strategies. Weigh aid (saves lives but risks dependency), trade and fair trade (reach only some farmers), debt relief (needs good governance) and the Sustainable Development Goals and Closing the Gap (frameworks with uneven progress).
Judgement. Conclude which strategies best address each scale and why. Markers reward inequality analysed within as well as between countries and a weighed verdict.
