What is unemployment? It’s when people who want to work can’t find a job. Think of it as a traffic jam on the road to a job – everyone’s waiting for a spot.
Unemployment rate \$u\$ is calculated as:
\$u = \dfrac{U}{L} \times 100\%\$
U = number of unemployed people, L = labour force (employed + unemployed).
Labour Force Participation Rate (LFPR) tells us how many people are actively looking for work:
\$\text{LFPR} = \dfrac{L}{P} \times 100\%\$
P = total working‑age population.
Business Cycle – cyclical unemployment rises during recessions and falls in booms. Example: 2008 financial crisis saw a spike to ~10% in the UK.
Long‑Term Structural Shift – as industries change (e.g., from coal to tech), certain skills become less in demand, leading to persistent unemployment in those sectors.
Frictional Turnover – always present; the job market is like a dance floor – people constantly change partners.
Historical Data (UK)
| Year | Unemployment Rate (%) |
|---|---|
| 2008 | 7.8 |
| 2010 | 7.5 |
| 2015 | 5.5 |
| 2020 | 4.4 |
| 2023 | 4.1 |
When the tech sector grows, older manufacturing jobs shrink. Workers with skills in assembly lines may find it hard to transition to coding or data analysis. This shift creates structural unemployment until they retrain.
Remember to:
💡 Tip: Use the “traffic jam” analogy to remember that frictional unemployment is normal, while cyclical and structural are problems to solve.
