What is unemployment?
In short
Unemployment means people who can work, want a job, and are looking for one, but do not have one.
In plain words
In the UK the official rate comes from a large household survey run by the Office for National Statistics. Someone is counted as unemployed if they are without work, have actively looked for a job in the last four weeks, and are available to start within two weeks. People who are not looking — including many students, carers, and people who are long-term sick or retired — are counted separately as economically inactive, not as unemployed.
A simple example
Three neighbours are out of paid work. One applies for jobs every week and could start on Monday. She is unemployed. One is a full-time student not looking for work. He is inactive. One has stopped applying after a long stretch with no replies. If she is no longer seeking work, the survey may class her as inactive, even though she would take a job. The headline rate misses that third story.
Why it matters
Losing work cuts income and can scar later pay and health. A high unemployment rate also tells the Bank of England and the government that the economy is wasting people who want to produce. A very low rate can mean firms struggle to hire, which sometimes feeds into wages and prices. The rate is an average. It can be low nationally and still high for a town, an age group, or an industry.
Easy to mix up
Not everyone without a job is unemployed. The claimant count — people on unemployment-related benefits — is a different statistic and does not match the survey. Underemployment is another idea again: people who have some work but want more hours. A fall in unemployment is good news only if people found work, not if they simply left the labour force.
