All persons aged 15-74 years old residing in the country. Persons staying abroad for more than one year are excluded. Starting from January 2000 the Finnish LFS has been a continuous survey, and therefore all weeks of a month are represented. The monthly survey is conducted as a continuous panel survey. The ultimate sampling unit is an individual person aged 15 to 74 years old.
Random selection is applied by region in proportion to population weights.
The sample is drawn twice a year, and it is updated monthly. For consecutive quarters 60 percent of sampled persons are common to both surveys. The first results are available after 3 weeks from the survey month. Since 1997 the Finnish Labour Force Survey has utilised the weighting calibration procedure using information on sex, age and region. As auxiliary information the register of job seekers is also used.
