Notes on Social Inequities, Health Inequities, and Poverty Measurement

Social Inequities

Social inequities refer to the unequal distribution of resources in society, leading to disparities in health outcomes among different groups of people. Key factors contributing to social inequities include income, poverty, and socioeconomic status (SES), which all have significant impacts on health.

Learning Objectives

  • Evaluate the evidence that shows income, poverty, and socioeconomic status adversely affect health.

  • Explain how health inequities arise in contexts of poverty and low socioeconomic status.

  • Identify different strategies to break the connection between financial factors and mental as well as physical health issues.

Understanding Health Inequities

Health inequities are defined as avoidable, unnecessary, and unjust differences in health outcomes among different population groups. According to Dahlgren and Whitehead (1991), health inequalities can be termed inequities when there is a failure of fairness or justice in the distribution of health resources.

Factors of Health Inequities

Health inequities manifest in various forms, influenced by various factors such as:

  • Ethnicity

  • Gender

  • Income

  • Nationality

  • LGBTQI+ status
    These dimensions influence individuals' experiences of health and access to healthcare.

Income Measurement Approaches

Income is often assessed using equalised household income, where the size of the household is factored into income calculations. The OECD modified scale is a common approach for equalising income, where the first adult receives a value of 1, subsequent adults receive 0.5, and children receive 0.3. Additionally, the square-root scale is another method of assessing income equity.

Considerations in Income Assessment

When measuring income for health equity research, several limitations arise:

  • Should income be examined as pre-tax or post-tax?

  • How do regional cost of living variations affect income assessments?

  • What is the impact of disposable income after housing costs?

  • Should levels of absolute or relative deprivation be analyzed when considering income?

Deprivation Definitions

Relative deprivation refers to feelings of being deprived compared to others, often stemming from social comparisons. In contrast, absolute deprivation occurs when an individual’s income falls below the minimum requirement needed for basic living costs.

Measuring Poverty

The definition of poverty is often comparative, focusing on how an individual's income stacks up against others. In Australia, a common threshold for poverty measurement is 50% of the median equivalised income. Additionally, the Henderson poverty line, which has been adjusted over time, serves as a benchmark for determining poverty levels.

Welfare Measures

Examining welfare impacts through several indicators is crucial. For instance, data indicates variations in weekly income units based on family structures (single, couple with children) and whether housing costs are included in the overall assessment of poverty.

Income Inequality: The GINI Coefficient

Developed by statistician Corrado Gini, the GINI coefficient measures income inequality on a scale from 0 (equal income for all) to 1 (one person earns all income). Values above 0 signify varying degrees of income disparity within a population, with scores above 0.6 indicating severe inequality.

Socioeconomic Status (SES)

SES encompasses more than just income; it includes education levels and the prestige of occupations. The Socioeconomic Indexes for Areas (SEIFA) assists in determining the socio-economic distribution across geographic areas in Australia, which further highlights disparities in income and education leading to health differences.

Health Gradient Evidence

Research indicates a strong correlation between SES, income, and health outcomes. Individuals from lower income households tend to have poorer health outcomes, contributing to higher rates of physical illnesses and mental health issues. Psychological explanations for this phenomenon highlight the importance of social cohesion and community support, which are often lacking in lower socioeconomic environments.

Stress and Health Inequities

Financial instability can lead to significant stress, which adversely affects physical and mental health. High levels of stress are reported in individuals with low income, impacting their general well-being and further perpetuating health inequities through generational poverty. The Family Stress Model outlines how financial stress influences parenting, child development, and overall family dynamics.

Strategies to Address Inequities

Improving health inequities involves a multifaceted approach, including:

  1. Strengthening individuals through education and support initiatives.

  2. Enhancing community resilience via local resources and engagement strategies.

  3. Improving access to essential services, particularly health care.

  4. Promoting broad macroeconomic changes to address systemic inequalities.

Addressing health inequalities effectively requires understanding the complex interplay of income, SES, and community factors, with targeted interventions at multiple levels.
