Unemployment means people who are without a job, available to work and actively looking. Its rate is the unemployed as a percentage of the labour force. Economists then ask why people are unemployed, because the cause decides which responses make sense.
This lesson follows the price lessons in inflation and unemployment and prepares the household comparisons later.
How is the rate measured?
Unemployment rate = unemployed ÷ labour force × 100, where labour force = employed + unemployed. Someone who is not looking for work is outside the labour force, so is not counted as unemployed.
What are the main types?
- Frictional: people between jobs, or new entrants, taking time to find a good match. Information is imperfect, so searching takes time.
- Structural: a lasting mismatch between available skills or locations and the jobs on offer, often when an industry shrinks or changes technology.
- Cyclical: caused by weak overall demand, so firms need fewer workers. It rises in a downturn and eases in a recovery.
- Seasonal: jobs that exist only at certain times of year, such as harvest or holiday resort work.
Worked example
The fictional town of Pantai Biru has 376,000 people in work and 24,000 unemployed.
Step 1, labour force: 376,000 + 24,000 = 400,000.
Step 2, rate: 24,000 ÷ 400,000 × 100 = 6%.
Step 3, classify the 24,000. A local report finds:
| Group | People | Type | Reason |
|---|---|---|---|
| Recent graduates and people switching jobs | 8,000 | frictional | searching for a good match |
| Weaving-mill workers after permanent closure | 10,000 | structural | their skills no longer match local jobs |
| Workers laid off when orders fell in a downturn | 6,000 | cyclical | weak demand across the economy |
Step 4, check: 8,000 + 10,000 + 6,000 = 24,000, which matches.
Step 5, interpret. Each group needs a different kind of explanation: faster information about vacancies, retraining, or recovery in demand. Calling all 24,000 “cyclical” would miss two of the three mechanisms.
The mistake to watch for
Mistaken answer: “4,000 unemployed people gave up looking, so the rate is now 20,000 ÷ 400,000 = 5%, and the economy improved.”
The student kept the labour force at 400,000, and also assumed jobs had been created.
If 4,000 leave the labour force, it becomes 396,000. The rate is 20,000 ÷ 396,000 ≈ 5.05%.
Employment is still 376,000, so no new jobs exist. The rate fell only because people stopped searching.
Check yourself
1. A labour force of 250,000 includes 15,000 unemployed. Calculate the unemployment rate.
Show answer
15,000 ÷ 250,000 = 0.06, so 6%.
2. Name the type: (a) a graduate searching for a first job, (b) a beach-resort worker out of work in the quiet season, (c) a typist whose role no longer exists after a technology change.
Show answer
(a) frictional, (b) seasonal, (c) structural.
3. There are 180,000 people employed and 20,000 unemployed. Find the labour force and the rate.
Show answer
Labour force = 180,000 + 20,000 = 200,000. Rate = 20,000 ÷ 200,000 = 10%.
Where this leads next
With the types clear, move to comparing effects on hypothetical households. The ratios tool helps you set up numerator and denominator, and the mixed practice set mixes this lesson with the others.
If you can calculate the rate but find the classification hard to justify, online one-to-one Economics tuition lets a teacher ask you “why that type?” until your reasoning is clear.
