Module 5: Priority Populations

🧠 1. Concise Study Notes

Key Concepts

Marginalisation

  • Involuntary exclusion of individuals or groups from social, economic, and political systems.

  • Limits access to resources, freedom, and opportunities, resulting in poverty and ill health.

  • Shaped by power structures, history, geography, and politics.

  • Can be experienced as not belonging or not being valued.

  • Determinants: social stigma, early life disadvantage, financial hardship, poor health, social isolation.

Social Exclusion

  • Processes (societal/institutional) that block full participation in society.

  • Can be active (denial of rights) or passive (economic policies causing exclusion).

  • Multi-dimensional — affects economic, cultural, political, and social participation.

  • Closely linked to marginalisation and stigma.

Stigma

  • Negative attitudes/judgements toward people based on certain traits (e.g. race, health status).

  • Involves labelling, stereotyping, and discrimination.

  • Reinforces “othering,” blame, and exclusion.

Intersectionality

  • Framework recognising overlapping systems of oppression (e.g. racism, sexism, classism).

  • Identities intersect to shape unique experiences of inequality.

  • Inequality arises from structures of power and privilege, not individual failings.

  • Example: Aboriginal women’s health shaped by both racism and sexism.

Priority Populations

  • Groups at greater risk of poor health due to social, economic, or geographical disadvantage.

  • Policies must address inequities across the whole gradient but with proportionally greater impact at the bottom (proportionate universalism).

Universal vs Targeted Approaches

  • Universal: applied to all (e.g. water fluoridation).

  • Targeted: directed to those most in need (e.g. dental services for low-income children).

  • Both are required for health equity.

Language & Ethics

  • Terms like “vulnerable” or “disadvantaged” may reinforce stigma.

  • Public health must focus on structural causes (colonisation, racism, poverty), not just behaviour.

  • Involve communities in designing culturally safe, empowering solutions.

🎯 2. Learning Outcomes (with short answers)

1. Describe the social, colonial, economic and cultural determinants of Aboriginal and Torres Strait Islander health.
Colonisation disrupted land, culture, family, and self-determination, causing intergenerational trauma, poverty, and marginalisation. Social determinants such as housing, employment, education, racism, and access to culturally safe care continue to shape poor health outcomes. Community-controlled health organisations work to restore cultural connection and equity through self-determined, holistic approaches.

2. Define and distinguish marginality, intersectionality, social exclusion and social inclusion.

  • Marginality: being pushed to the edges of society, limiting access to resources.

  • Social Exclusion: active or passive denial of participation in social/economic life.

  • Intersectionality: multiple, overlapping systems of oppression shaping experiences.

  • Social Inclusion: ensuring full participation and equity—but must address power, not just “fitting in”.

3. Understand how categories of oppression interact and contribute to systemic inequality. 
Systems like racism, sexism, and classism intersect to create compounding disadvantage. For example, an Aboriginal woman may face racial, gender, and economic discrimination simultaneously. Understanding these intersections helps design equitable policies that tackle root causes rather than symptoms.

✏ 3. Example Short-Answer Questions (100–150 words each)

Q1: What is marginalisation and how does it impact health?

Marginalisation refers to the involuntary exclusion of individuals or groups from mainstream social, economic, and political systems, restricting their access to resources, rights, and opportunities. It is shaped by power relations and systemic structures such as colonisation, racism, and economic inequality. People who experience marginalisation often face poverty, poor housing, unemployment, and limited access to healthcare, leading to worse health outcomes. For instance, Aboriginal and Torres Strait Islander peoples have historically been marginalised through policies that removed land and cultural rights, resulting in intergenerational trauma and health inequities. Addressing marginalisation requires structural change that restores agency, equity, and inclusion in decision-making.

Q2: Explain the relationship between stigma, marginalisation, and social exclusion.

Stigma, marginalisation, and social exclusion are interconnected processes that contribute to systemic inequality. Stigma involves negative judgments or stereotypes toward individuals based on characteristics such as race, health status, or behaviour. This stigma can lead to marginalisation — being pushed to the social or economic periphery — and social exclusion, where individuals are denied participation in societal life. These processes reinforce disadvantage and limit access to healthcare, employment, and social support. For example, people who inject drugs may face stigma and exclusion from health services, worsening health outcomes. Public health must address these structural drivers, not just individual behaviours, to promote equity.

Q3: What is intersectionality and why is it important in public health?

Intersectionality recognises that people’s experiences of inequality are shaped by multiple, overlapping identities such as race, gender, class, and ability. These intersections interact with systems of power and oppression to create unique health vulnerabilities. In public health, applying an intersectional lens helps practitioners understand how structural inequalities produce differential outcomes. For example, Aboriginal women may experience combined effects of racism, sexism, and economic disadvantage, contributing to poorer health. Without considering intersectionality, policies risk oversimplifying populations and reinforcing inequities. Recognising intersecting identities ensures public health interventions are equitable, culturally safe, and responsive to real-world diversity.

Q5: Scenario – Designing a program for Aboriginal and Torres Strait Islander health equity.

Question: Using the concept of marginalisation, explain how a public health practitioner could design an equitable health program for Aboriginal and Torres Strait Islander peoples.

An equitable program must first acknowledge the ongoing effects of colonisation—dispossession, forced removals, and systemic racism—which have created lasting marginalisation and health inequities. A public health practitioner should partner with Aboriginal community-controlled organisations (ACCHOs), ensuring community ownership and leadership. Programs must be culturally safe, respect self-determination, and draw on strengths such as cultural identity, kinship, and connection to Country.
Using an intersectional approach helps identify overlapping determinants—such as poverty, education, gender, and trauma—that shape health outcomes. For example, improving maternal health could involve integrating culturally appropriate antenatal care with community support and trauma-informed counselling. Structural barriers, like limited access to services in remote areas, should be addressed through policy advocacy and resource redistribution. True equity requires shifting power from institutions to communities, recognising Aboriginal people as partners, not patients, in health improvement.

Q6: Scenario – Universal vs Targeted Interventions.

Question: Discuss the advantages and limitations of universal versus targeted interventions in reducing health inequalities.

Universal interventions (e.g. vaccination, fluoridation) reach entire populations and can promote equity when access is not resource-dependent. However, they may inadvertently benefit advantaged groups more, widening gaps. Targeted interventions (e.g. free dental care for low-income families) focus resources on those with greatest need, improving fairness but risking stigma or exclusion if poorly designed.
The most effective approach is proportionate universalism: combining universal coverage with greater intensity for disadvantaged groups. For instance, national immunisation programs can include mobile outreach in remote Indigenous communities. Public health practitioners must also ensure interventions address structural barriers like racism and poverty. Universal approaches alone cannot overcome systemic inequities; targeted, culturally informed actions are needed to ensure those most affected by disadvantage experience proportionally greater benefits.
