Economic inequality refers to the disparities in income and wealth distribution among individuals and groups within a society.
It remains a significant social and economic issue, contributing to various societal challenges and unrest.

Methods to measure inequality include:
1. Share of Income: Percentage of income held by the top 1% or 10% of the population.
- Issue: This method doesn’t provide information on the entire population's income; it skews focus towards the wealthiest individuals and may overlook changes in the lower percentiles.
1. Income per Capita by Decile: Income levels are calculated across deciles and expressed in constant dollars (e.g., 2005 USD PPP).
2. Dispersion Ratios: Such as the 90th/10th percentile ratio, indicating income inequality across broader distributions.
- Drawback: Fails to represent middle-income dynamics effectively.
1. Lorenz Curve and Gini Coefficient:
- Lorenz Curve: Graphically represents income distribution, allowing for the comparison of the degree of inequality across populations.
- Gini Coefficient: A numerical measure of inequality calculated as the area between the Lorenz curve and the line of perfect equality (Gini = A/(A+B)).
  - Values range from 0 (perfect equality) to 1 (maximum inequality).
  - Example values:
    - South Africa Gini 1990: 0.63; South Africa Gini 2010: 0.70.

Inequality within countries has been increasing since the 1980s, although there was an overall decrease following significant political and economic shifts in various nations.
The challenge remains in balancing economic growth with the demand for basic income equity.

Types of inequality include:
- Intergenerational Inequality: Inequalities that persist across generations, often linked to wealth transmission, social status, and educational opportunities.
- Categorical Inequality: Refers to economic differences based on inherent characteristics like gender, race, or citizenship.

The consequences of inequality include reduced social coherence, increased crime rates, mental illness, lower educational attainment, and a myriad of health-related issues.
A growing debate surrounds optimal inequality levels in society:
- When is inequality viewed as unfair? Individuals tend to consider inequality as unjust when it arises from categorical differences or systemic failings rather than individual effort or risk-taking.

Factors influencing economic inequality include:
- Education level and quality, employment opportunities, skill availability, and societal structures.
Roles of Technology and Institutions:
- Technology can exacerbate income disparities by concentrating wealth and job opportunities among skilled workers at the expense of low-wage laborers.
- Institutional policies affecting labor markets, property rights, access to funding, and educational equity all play crucial roles in shaping economic outcomes.

Policy Strategies to mitigate economic inequality include:
- Redistributive Policies: Direct taxes and transfers aimed at lowering disposable income inequality by addressing wealth concentration.
- Predistributive Policies: Initiatives aimed at equalizing opportunities from the outset, such as education and minimum wage legislation.
Social Grants & Welfare Systems:
- Progressive in nature, targeting those in lower income brackets (e.g., child support grants).
Importance of sustained investments in quality education and systemic reform to democratize ownership in the economy.

Understanding trends and mechanisms of economic inequality are critical for developing informed policy responses in South Africa and globally.
