Measures of Unemployment

How is unemployment measured?
The Claimant Count measure includes people who are eligible to claim the Job Seeker's Allowance (JSA). The data is seasonally adjusted to take into account predictable seasonal changes in the demand for labour.
The Labour Force Survey counts those who are without any kind of job including part time work but who have looked for work in the past month and are able to start work immediately. The figure includes those people who have found a job and are waiting to start in the next two weeks.
