The sample is randomly drawn and it represents an image of the entire population. If we replace one person with another, it causes an imbalance in the data, because the sample then no longer is random.
We would like to interview you four times in total. By interviewing the same people several times, it produces the best measurement of changes over time, such as people work more hours than they did last time they were interviewed etc.
The sample includes people aged 15-74 at the time of the first interview. Because of the panel structure some persons can be up to 76 years at the time the interview is completed.
The sample is designed so that the unemployed persons have a higher probability of being selected to ensure a sufficient number of responses from the unem-ployed. In calculating the results this is taken into account so that the num¬bers reflect the actual composition of the population.
The survey is a rotating panel survey with four panels. This means that a person participates several times in the survey. A design with four panels means that one fourth of the sample is replaced each quarter. This design is important to calculate quarterly and annual changes in e.g. unemployment and employment.
