The Meaning of Economic Inequality

Economic inequality refers to differences in the distribution of income and wealth among individuals or groups within an economy.

It shows that some people possess significantly more economic resources than others.

Economic inequality exists in nearly all economies, although the degree of inequality varies between countries.

Main Forms of Economic Inequality

The two major forms of economic inequality are:

Unequal Distribution of Income

Income inequality refers to differences in the amount of income earned by individuals or households.

Income is the flow of earnings received over a period of time.

Sources of income include:

• Wages and salaries
• Rent
• Interest
• Profits
• Dividends
• Transfer payments

Meaning of Unequal Income Distribution

Income inequality exists when:

• Some individuals or households earn much higher incomes than others.
• Income is unevenly shared across the population.

Examples of Income Inequality

• Highly skilled workers earning much higher wages than low-skilled workers.
• Business owners receiving large profits while some workers earn minimum wages.

Causes of Income Inequality

• Differences in education and skills
• Differences in occupation
• Unequal access to opportunities
• Discrimination
• Differences in ownership of assets
• Globalization and technological change

Effects of Income Inequality

• Differences in living standards
• Differences in access to healthcare and education
• Higher poverty levels for some groups
• Potential social tensions

Unequal Distribution of Wealth

Wealth inequality refers to differences in the ownership of assets among individuals or households.

Wealth is the stock of assets owned at a point in time.

Examples of wealth include:

• Property and land
• Savings
• Shares and financial investments
• Businesses
• Valuable possessions

Meaning of Unequal Wealth Distribution

Wealth inequality exists when:

• Some individuals own significantly more assets than others.
• Wealth is concentrated among a small part of the population.

Why Wealth Inequality Is Often Greater Than Income Inequality

• Wealth accumulates over time.
• Assets generate additional income.
• Wealth may be inherited across generations.

Wealth → Generates income → More wealth accumulation

Examples of Wealth Inequality

• A small group owning most land or property in a country.
• Wealthy households owning large investment portfolios while others have little or no savings.

Causes of Wealth Inequality

• Inheritance
• Differences in savings and investment
• Unequal property ownership
