Labour, Poverty & Inequality Study Guide

Introduction

Labour, poverty, and inequality are closely connected economic and social topics. Labour markets determine how people find work, earn income, develop skills, and contribute to production. Poverty concerns whether individuals and households have enough resources to meet basic needs and participate in society. Inequality examines how unevenly income, wealth, opportunities, or other resources are distributed.

These subjects are related but are not identical. A country can reduce extreme poverty while still experiencing high income inequality. A person may have employment but remain poor if earnings are very low, hours are insufficient, or household needs are high.

Economists, governments, the International Labour Organization (ILO), World Bank, United Nations, and national statistical agencies use indicators such as employment, unemployment, wages, poverty rates, and the Gini coefficient to study these issues.

·         Distinguish poverty from inequality.

·         Describe major factors that influence wages, poverty, and economic opportunity.

What is Labour?

In economics, labour refers to human effort used in producing goods and services.

Labour includes both physical and mental work.

Examples include:

·         Construction

·         Farming

·         Teaching

·         Nursing

·         Programming

·         Manufacturing

·         Transportation

·         Accounting

Labour is traditionally considered one of the major factors of production, along with land, capital, and entrepreneurship.

Work vs Employment

In everyday conversation, work and employment are often treated as synonyms. In labour statistics, they have different meanings.

The ILO defines employment as activity performed to produce goods or provide services for pay or profit. Work is broader and can also include unpaid activities such as volunteer work and some forms of production for household use.

This distinction is important because economically valuable activities are not always paid employment.

The Labour Market

A labour market connects workers who supply labour with employers who demand labour.

Workers offer:

·         Time

·         Skills

·         Knowledge

·         Experience

·         Physical effort

Employers offer compensation, which may include:

·         Wages

·         Salaries

·         Bonuses

·         Benefits

Labour markets differ according to education requirements, occupation, geography, technology, regulations, and economic conditions.

Labour Force

The labour force generally consists of people who are either:

·         Employed, or

·         Unemployed but actively seeking and available for employment.

The ILO's statistical framework defines unemployment using conditions that include being without employment, seeking work, and being available to begin work.

Therefore:

Labour Force = Employed + Unemployed

People who are neither employed nor currently meeting the statistical requirements for unemployment are classified as outside the labour force.

Examples may include some:

·         Students

·         Retired people

·         Full-time unpaid caregivers

·         People not currently seeking employment

Labour Force Participation Rate

The labour force participation rate shows what share of the working-age population participates in the labour market.

A simplified formula is:

Labour Force Participation Rate = Labour Force ÷ Working-Age Population × 100

This measure differs from the unemployment rate.

Unemployment

Unemployment occurs when people who are available for employment and seeking work cannot find jobs under the relevant statistical definition.

The basic formula is:

Unemployment Rate = Unemployed People ÷ Labour Force × 100

Example

Suppose a country has:

·         9 million employed people

·         1 million unemployed people actively seeking work

The labour force is:

9 million + 1 million = 10 million

The unemployment rate is:

1 ÷ 10 × 100 = 10%

Types of Unemployment

Frictional Unemployment

Frictional unemployment occurs when people are temporarily between jobs.

For example, a graduate may spend several weeks searching for a suitable first job.

Structural Unemployment

Structural unemployment occurs when workers' skills, locations, or experience do not match available jobs.

Technological and industrial changes can contribute to structural unemployment.

Cyclical Unemployment

Cyclical unemployment is associated with declines in economic activity.

During recessions, lower demand may cause businesses to reduce production and employment.

Seasonal Unemployment

Some employment changes predictably with the seasons.

Examples can occur in:

·         Agriculture

·         Tourism

·         Construction

·         Holiday-related businesses

Underemployment

A person can have a job but still be underemployed.

Underemployment may occur when a worker:

·         Works fewer hours than desired.

·         Wants additional employment.

·         Has skills that are not fully used.

This is why the unemployment rate alone does not capture every form of labour underutilization.

Formal and Informal Employment

Formal employment generally operates within established legal and regulatory arrangements involving matters such as employment law, taxation, registration, and social protection.

Informal employment involves jobs that are not effectively covered by relevant formal arrangements.

The ILO's current statistical approach includes informal jobs that lack effective coverage through arrangements such as labour legislation, taxation, commercial registration, or social-security rules. Informal employment can occur even within a formally registered enterprise.

Common Mistake

Informal employment ≠ illegal employment

Informality concerns the employment arrangement and its coverage by formal systems. It does not automatically mean the underlying activity is criminal.

Wages

A wage is remuneration received for work.

Wages may be calculated:

·         Hourly

·         Daily

·         Weekly

·         Monthly

·         By output or piece rate

The ILO uses the term wages broadly for remuneration or earnings paid by employers to employees for work or services.

Nominal Wage

A nominal wage is the amount of money a worker receives.

Example:

$2,000 per month

Real Wage

A real wage adjusts earnings for changes in purchasing power.

Suppose a worker's wage rises by 4%, but consumer prices rise by 7%.

Although the worker earns more money in nominal terms, their purchasing power may have fallen.

Memory Tip

Nominal wage → money amount

Real wage → purchasing power

What Determines Wages?

Wages can be influenced by many factors, including:

·         Education

·         Skills

·         Experience

·         Productivity

·         Occupation

·         Labour demand

·         Supply of workers

·         Bargaining arrangements

·         Minimum-wage laws

·         Location

·         Economic conditions

Differences in wages therefore do not have one single cause.

Human Capital

Human capital refers to productive knowledge, skills, experience, and abilities embodied in people.

Human capital can be developed through:

·         Education

·         Training

·         Experience

·         Health

·         Skill development

Greater skills can raise productivity and expand employment opportunities, although educational qualifications alone do not guarantee high earnings.

Minimum Wage

A minimum wage is the minimum remuneration an employer is legally required to pay covered workers for work performed during a specified period.

The ILO notes that minimum-wage systems are intended to protect workers against unduly low pay and generally operate alongside other labour and social policies.

The economic effects of a minimum wage can depend on factors such as:

·         The level at which it is set

·         Enforcement

·         Worker productivity

·         Labour demand

·         Informality

·         Industry conditions

·         Other labour-market institutions

For that reason, the effects of minimum-wage changes can vary between countries, sectors, and time periods.

Poverty

Poverty describes serious deprivation in resources or living conditions.

Poverty can affect access to:

·         Food

·         Safe water

·         Housing

·         Health care

·         Education

·         Energy

·         Transportation

·         Employment opportunities

Economists distinguish several ways of measuring poverty.

Absolute Poverty

Absolute poverty uses a threshold intended to represent a minimum level of resources or consumption.

People below that threshold are classified as poor according to the measure.

The World Bank uses an international poverty line to compare extreme poverty across economies using purchasing-power adjustments. Following its June 2025 methodology update, the international extreme-poverty line is $3.00 per person per day in 2021 purchasing-power-parity dollars.

This line is primarily a tool for international comparisons.

For domestic policymaking, the World Bank emphasizes that a country's own national poverty line is generally more appropriate because it reflects local conditions.

Relative Poverty

Relative poverty compares a person's resources with typical living standards in the society where they live.

A relative poverty line might be expressed as a percentage of median household income.

This means the threshold can rise as the typical income of society increases.

Absolute vs Relative Poverty

Multidimensional Poverty

Income alone cannot describe every form of deprivation.

Multidimensional poverty examines disadvantages across several areas of life.

The UNDP's global Multidimensional Poverty Index (MPI) examines deprivations involving three broad dimensions:

·         Health

·         Education

·         Living standards

Indicators include factors such as schooling, nutrition, sanitation, electricity, housing, and household assets.

The 2025 Global MPI estimates that about 1.1 billion people across the 109 countries covered by the index experience multidimensional poverty.

Important Point

Income poverty and multidimensional poverty measure different things.

A household can experience serious educational, health, or housing deprivation even when an income measure alone does not capture the full situation.

Poverty Gap

A poverty rate tells us how many people fall below a poverty threshold.

It does not tell us how far below the threshold they are.

A poverty gap measure helps describe the depth of poverty by considering the distance between poor people's resources and the poverty line.

Two places can therefore have the same poverty rate but different depths of poverty.

What Is Inequality?

Economic inequality describes differences in economic resources among individuals or households.

It can involve:

·         Income

·         Wealth

·         Wages

·         Consumption

·         Opportunities

Poverty and inequality should not be confused.

Example

Suppose every household's income doubles.

Extreme poverty could fall dramatically, but relative inequality could remain almost unchanged if everyone's income increased in the same proportion.

Income Inequality

Income inequality concerns how unevenly income is distributed.

Income may come from:

·         Wages

·         Business income

·         Investments

·         Pensions

·         Government transfers

Economists can measure inequality before or after taxes and transfers.

The OECD, for example, often measures household disposable income after taxes and cash transfers when studying income distribution.

Wealth Inequality

Wealth is different from income.

Income is a flow received during a period.

Wealth is a stock of accumulated assets minus liabilities.

Assets may include:

·         Homes

·         Land

·         Savings

·         Shares

·         Businesses

Liabilities may include:

·         Mortgages

·         Loans

·         Other debts

A person may therefore have moderate annual income but substantial accumulated wealth.

Lorenz Curve

The Lorenz curve is a graphical method for showing the distribution of income or consumption.

The population is ranked from poorest to richest.

The graph compares:

·         Cumulative share of population

·         Cumulative share of income or consumption

If everyone received exactly the same amount, the Lorenz curve would follow the line of perfect equality.

The farther the actual curve lies from that line, the greater the inequality.

Gini Coefficient

The Gini coefficient is one of the most widely used measures of inequality.

Depending on presentation, it ranges from:

0 to 1

or:

0 to 100

A value of:

0 = perfect equality

A value approaching:

1 or 100 = greater measured inequality

The World Bank calculates the Gini from the Lorenz curve and notes that different distributions can sometimes produce the same Gini value, so it should not be treated as a complete description of a society's economic distribution.

Memory Tip

Low Gini → more equal distribution

High Gini → more unequal distribution

Equality vs Equity

These words are related but different.

Equality generally refers to people receiving the same amount, treatment, or formal opportunity.

Equity usually concerns fairness while recognizing differences in needs or circumstances.

Their precise meanings depend on context, so they should not be used interchangeably without explanation.

Factors That Can Influence Inequality

Economic inequality can be affected by many interacting forces, including:

·         Education

·         Technology

·         Globalization

·         Labour-market institutions

·         Employment patterns

·         Property ownership

·         Inheritance

·         Taxation

·         Government transfers

·         Demographics

·         Regional differences

Different forms of inequality can move in different directions at the same time.

For example, wage inequality may fall while wealth inequality rises.

Social Mobility

Social mobility describes movement between socioeconomic positions.

Intragenerational Mobility

Movement during one person's lifetime.

Example:

A worker begins in a low-paying occupation and later enters a much higher-paying profession.

Intergenerational Mobility

Differences in economic position between generations.

Example:

Children attaining a substantially different income or occupational position from their parents.

High inequality and low mobility are related questions but are not identical concepts.

Poverty, Employment, and the Working Poor

Having employment does not automatically eliminate poverty.

A person may be working but still have low household resources because of:

·         Low wages

·         Too few working hours

·         Large household needs

·         Irregular employment

·         High living costs

Such situations are often described as working poverty.

This distinction demonstrates why employment quantity and job quality are both relevant when studying living standards.

Social Protection

Social protection includes programs designed to protect people against economic and social risks.

Depending on the country, programs can include:

·         Unemployment benefits

·         Pensions

·         Disability benefits

·         Child benefits

·         Health protection

·         Cash transfers

The ILO notes that workers in informal employment often have weaker access to social protection, making extension of coverage an important labour-policy challenge.

Taxes and Transfers

Governments can alter the distribution of disposable income through:

·         Taxes

·         Cash benefits

·         Pensions

·         Social assistance

Economists often compare inequality in market income with inequality in disposable income after taxes and transfers to study redistribution. The OECD uses this approach when examining how government systems affect income distribution.

The size and effects of redistribution vary considerably among countries.

Education and Skills

Education and skills can influence:

·         Employment opportunities

·         Productivity

·         Earnings

·         Occupational choice

However, unequal access to high-quality education can itself contribute to unequal opportunity.

Education therefore appears on both sides of the topic:

It can increase mobility, but unequal access can reinforce existing differences.

Common Mistakes

Unemployed Does Not Mean Everyone Without a Job

People normally must be seeking and available for employment to be classified as unemployed under international statistical standards.

Employment and Work Are Not Identical

Employment is work performed for pay or profit. Other forms of unpaid work also exist.

Poverty and Inequality Are Not the Same

Poverty concerns insufficient resources relative to a threshold.

Inequality concerns how unevenly resources are distributed across a population.

Income and Wealth Are Different

Income → flow over time

Wealth → accumulated stock of assets minus liabilities

A Low Unemployment Rate Does Not Automatically Mean Every Worker Has a Good Job

The unemployment rate does not fully capture low wages, underemployment, unsafe work, or informality.

Gini Does Not Measure Poverty

The Gini coefficient measures inequality in a distribution.

A society can have a relatively low Gini while still having widespread poverty if most people have similarly low incomes.

Memory Tips

Remember:

Labour force = employed + unemployed

Unemployment rate = unemployed ÷ labour force

Nominal wage = money

Real wage = purchasing power

Absolute poverty = basic threshold

Relative poverty = compared with society

MPI = multiple deprivations

Income = flow

Wealth = stock

Gini = inequality

0 Gini = equality

Summary

Labour economics studies how workers and employers interact, how wages are determined, and why employment and unemployment change. The labour force consists of employed people plus unemployed people who meet conditions such as seeking and being available for work.

Poverty measures deprivation. Absolute measures compare resources with a defined threshold, while relative poverty compares living standards within a society. Multidimensional approaches broaden the analysis to health, education, housing, and other conditions.

Inequality measures how unevenly resources are distributed. Income inequality, wealth inequality, wage inequality, and inequality of opportunity describe related but different questions. The Lorenz curve and Gini coefficient are widely used to summarize income or consumption inequality.

The key lesson is that employment, poverty, and inequality overlap without being interchangeable. Understanding the distinctions between them is essential for economics and social-policy quizzes.

FAQ

What is the labour force?

The labour force consists broadly of employed people plus unemployed people who are seeking and available for employment.

What is the unemployment rate?

It is the number of unemployed people divided by the total labour force, usually expressed as a percentage.

What is underemployment?

Underemployment occurs when workers have employment but their labour is not fully used, such as when they want more working hours.

What is a minimum wage?

A minimum wage is the legally required minimum remuneration that covered employers must pay workers for a specified period of work.

What is extreme poverty?

For global comparison, the World Bank currently uses an international extreme-poverty line of $3.00 per person per day in 2021 PPP terms, following its 2025 methodology update. National poverty lines remain more suitable for many country-specific purposes.

What is multidimensional poverty?

It describes overlapping deprivations in areas beyond income, such as health, education, and living standards.

What is income inequality?

Income inequality describes how unevenly income is distributed across a population.

What does the Gini coefficient measure?

It summarizes inequality in an income or consumption distribution. Lower values represent more equal distributions, while higher values represent greater inequality.

What is the difference between income and wealth?

Income is money or resources received over time. Wealth is the accumulated value of assets minus liabilities.

Can poverty fall while inequality rises?

Yes. If lower-income households become better off but higher-income households experience much larger gains, poverty can fall while inequality increases.

Key Takeaways

·         Labour markets connect workers supplying skills and effort with employers demanding labour.

·         Employment, unemployment, underemployment, and informal employment measure different aspects of labour-market conditions.

·         Poverty can be measured through income thresholds, relative living standards, or multidimensional deprivation.

·         Inequality describes differences in the distribution of income, wealth, wages, or opportunities; the Gini coefficient is a common summary measure.

·         Poverty reduction, employment growth, and inequality reduction are related goals, but progress in one does not automatically produce progress in the others.
