Definitions of equity, equality, and social justice in the context of health; the difference between health inequity and health inequality; the principles of equity, diversity, and supportive environments

The Equity and Health option starts with definitions because the words are often used interchangeably in everyday speech but mean different things in public health. This dot point covers the conceptual scaffolding for the rest of the option.

Equality versus equity

Equality means giving everyone the same. Same resources, same access, same opportunities.

Equity means giving people what they specifically need to reach the same outcome. The needs differ between people and groups, so equal treatment does not produce equal outcomes.

The classic illustration: three people of different heights trying to watch a sports game over a fence. Giving each person the same-sized box (equality) leaves the shortest still unable to see. Giving each person a different-sized box that brings them all to the same eye level (equity) lets everyone see.

In Australian health, equality would mean every patient gets the same Medicare items. Equity means specific programs (the 715 Aboriginal and Torres Strait Islander health check, dedicated maternal child health for refugees, additional mental health items for under-25s) that address unequal starting points and unequal needs.

The shift in public health discourse over the last decade has been from equality (a 1990s framing) to equity (the contemporary framing). The shift reflects evidence that equal treatment is not sufficient to close gaps caused by unequal starting positions.

Health inequality versus health inequity

Health inequality is any difference in health outcomes between groups. Some inequalities are biological and unavoidable (older people have more cardiovascular disease than younger people).

Health inequity is a difference in health outcomes that is unjust and avoidable. The Indigenous life expectancy gap is a health inequity, not just a health inequality - it is produced by historical and ongoing structural factors that could be addressed by policy.

The distinction matters because public health resources should target inequities (where intervention is justified) rather than every inequality (some of which are biological or otherwise not modifiable).

Social justice principles

The same three principles introduced in Core 1 form the spine of equity work.

Equity

Already defined. Fairness in access and outcomes, recognising that different groups need different things.

In practice this means:

• Targeted programs for groups experiencing inequities (rather than universal-only programs).
• Cultural safety in service delivery.
• Means-tested supports (Medicare rebate variations, low-income housing).

Diversity

Recognising that different population groups have different needs, experiences, and contexts.

In practice this means:

• Services that account for cultural, linguistic, religious, and identity differences.
• Workforce that reflects population diversity.
• Information available in multiple languages and accessible formats.

Diversity is not just about acknowledging difference; it requires designing services that work across difference.

Supportive environments

Physical, social, economic, and political environments that protect and promote health.

In practice this means:

• Built environments (housing, transport, green space) that support healthy living.
• Social environments (workplaces, schools, community settings) that support wellbeing.
• Economic environments (income support, employment conditions) that enable health.
• Political environments (regulation, policy, advocacy) that prioritise health.

A health system can work hard at the individual level and still fail if the environment systematically undermines health for specific groups.

How equity is identified

Inequities are identified through:

• Disaggregated data. Health statistics broken down by Indigenous status, socioeconomic position, geographic location, sex, age, cultural background, disability, sexuality. Aggregate statistics hide inequities; disaggregated statistics reveal them.
• Community voice. Affected communities often identify inequities before official statistics catch up. The HIV community in the 1980s, mental health peer voices in the 2000s, climate-affected communities in 2020s.
• Comparative analysis. Comparing Australian data with international benchmarks (OECD comparisons), or specific group data with the general population.

How equity is addressed

Equity-focused public health uses several levers:

• Targeted programs. Resources directed to specific groups (Indigenous health, refugee health, rural mental health).
• Universal programs with equity components. Programs like Medicare or school education that serve everyone but have specific provisions for groups with higher needs.
• Structural reform. Changes to housing, income, employment, justice, education that affect the underlying determinants of health.
• Community empowerment. Funding and supporting community-controlled organisations to design and deliver their own services (ACCHOs, refugee community health services, LGBTIQ+ community organisations).

How this dot point sits in the option

This dot point provides the conceptual framework. The rest of the option applies it to:

• Specific groups experiencing health inequities (Indigenous, low-SES, rural, women, LGBTIQ+, people with disability).
• The role of determinants in producing inequities.
• The role of government, community, and individuals in addressing inequities.
• The link between health inequity and broader social inequity.

Strong HSC responses use the definitions precisely throughout the option. "Equality" and "equity" should not be used interchangeably in an extended response that pays attention to the syllabus.
