Being unemployed is not the same as not having a job. A retired person, a full-time student and a stay-at-home parent are all jobless, and none of them counts. Get that definition right and the whole topic — the rate, the types, the diagrams — falls into place.
📚 What you need to know
Someone is unemployed if they are not working but actively seeking work.
The labour force = people employed + people unemployed. Everyone else is economically inactive.
Unemployment rate = (unemployed ÷ labour force) × 100.
It is measured two ways: the ILO labour force survey and the claimant count.
Five types: real wage, structural, cyclical, frictional and seasonal.
The natural rate (NRU) = frictional + seasonal + structural. It is why 0% unemployment is impossible.
Who counts, and who does not
This diagram answers most calculation questions on its own. If a table gives you the population and the number of full-time students, they are almost always distractors.
Two ways of measuring it
Feature
ILO labour force survey
Claimant count
How it works
A large sample of households is surveyed every quarter
Counts people claiming unemployment benefit
Who decides
Respondents self-assess against ILO criteria
The benefit rules decide
How strict
Broader: ready to start soon and looking recently
Stricter: you must qualify for and claim the benefit
Main strength
The same method is used worldwide, so comparisons are meaningful
Cheap, fast and comes from records that already exist
Main weakness
It is a sample, so there is sampling error
Misses anyone unemployed who does not or cannot claim
WORKED EXAMPLE
Calculating the unemployment rate
A country has a population of 5,000,000; a labour force of 3,200,000; 2,912,000 people employed; and 400,000 full-time students. Calculate the unemployment rate.
Step 1: pick out what is usefulTotal population and full-time students are distractors. Students are not in the labour force.Step 2: find the number unemployedlabour force − employed = 3,200,000 − 2,912,000= 288,000 unemployedStep 3: apply the formula(288,000 ÷ 3,200,000) × 100Unemployment rate = 9%Divide by the labour force. Dividing by 5,000,000 would give 5.76% — a classic lost mark.
The five types of unemployment
Type
What causes it
Example
Real wage
Wages are held above the market equilibrium, so supply of labour exceeds demand
A minimum wage set above the going rate for young workers
Structural
The skills workers have no longer match the jobs available
Coal miners in a region where the pits have closed
Cyclical (demand deficient)
AD falls in a downturn, so firms need fewer workers
Redundancies across a whole economy during a recession
Frictional
Workers moving between jobs by choice
Someone who quit in March and starts a new job in May
Seasonal
Demand for that work only exists part of the year
Fruit pickers, ski instructors, seaside hotel staff
The natural rate of unemployment
NRU = frictional + seasonal + structural unemployment
Cyclical unemployment is the one that comes and goes with the business cycle, so it is not part of the natural rate. That is why the NRU is described as the lowest achievable level of unemployment, not zero.
Real wage unemployment on a diagram
Note that everyone between Qd and Qs wants to work at this wage. That is what makes it involuntary unemployment rather than people choosing leisure.
Cyclical unemployment is best drawn with two diagrams side by side: AD shifting left in the AD/AS model, and the demand for labour shifting left in the labour market. Demand for labour is derived from demand for goods, so the two move together.
Why the headline rate can mislead
Underemployment. An architect working part time in a gym is counted as employed, even though their skills are wasted and they want more hours.
Hidden unemployment. After a long search some people give up. Once they stop looking they leave the labour force, and the unemployment rate falls — which looks like good news but is not.
Disparities. The headline figure is an average. It can hide large gaps between regions, age groups and ethnic groups.
The trap in the data. Because discouraged workers leave the labour force, a falling unemployment rate is not proof that things are improving. Check whether employment is rising too. If it is not, people have stopped looking rather than started working.
The costs of unemployment
Who is affected
How
Individuals
Lost income, loss of skills over time, stress and poorer physical and mental health
The government
Less income tax revenue and more spending on benefits and retraining
Firms
Weaker consumer spending now, and difficulty finding skilled staff once recovery begins
The economy
Output below potential, so a negative output gap and wasted resources
Society
Higher rates of poverty, homelessness and social problems in badly hit areas
💡 Exam tip
Divide by the labour force, never the population. This is the most common calculation error in the whole topic.
Name the type of unemployment in your answer. Different types need completely different policies.
Cyclical unemployment is fixed by demand-side policy; structural unemployment needs supply-side policy such as retraining.
Use the phrase natural rate of unemployment and say what it is made of.
Underemployment and hidden unemployment are ready-made evaluation points.
Label the labour market diagram with D and S of labour, and put quantity of labour on the horizontal axis.
⚠️ Common mix-up
Counting everyone without a job as unemployed. You must be actively seeking work.
Thinking full employment means 0%. Full employment is the natural rate, not zero.
Including cyclical unemployment in the NRU. It is not there — only frictional, seasonal and structural.
Confusing underemployment with unemployment. Underemployed people are working.
Assuming a falling rate is always good. It can mean people have given up looking.
Using goods-market axes on a labour market diagram. It is wage rate and quantity of labour.
