Global Patterns of Inequality (SACE Stage 2 Geography Social and Economic Change)

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.
