Since the 4th quarter of 1999, the reference week of observation in the middle month of a quarter has been replaced by the continuous observation method (a mobile observation week).
Since the 1st quarter of 2001, the survey methodology has been adjusted to the EUROSTAT recommendation.
Since the 2nd quarter of 2003, the LFS results have been generalized to the total population with the use of the data on population of Poland (population aged 15 years old and more) from the balances compiled on the basis of the results of the Population and Housing Census 2002. Therefore, the LFS results from 2003 onwards are not fully comparable with the results from the previous years. The data presented in the publication for the 1st quarter of 2003 were recalculated in accordance with the new base for generalization of the results.
Since the 1st quarter of 2004, the survey has also included the foreign members of the households in the selected dwellings.
The Labour Force Survey has been carried out in Poland quarterly since May 1992. It has been improved in accordance with the Eurostat recommendations. The legal basis of the LFS provides the annual Regulation of the Council of Ministers concerning the programme of statistical surveys of official statistics. The survey concentrates on the situation from the point of view of the economic activity of the population, i.e. the fact of being employed, unemployed or economically inactive in the reference week.

The Labour Force Survey is the probability sample survey. Its results are generalized on the general population.
Since the fourth quarter of 1999, the observation of the reference week in the middle month of a quarter has been replaced by the continuous observation method, which means that in each of the 13 weeks of a quarter 1/13th part of the quarterly sample of dwellings is surveyed. It allows presenting the situation on the labour market during a whole quarter.
The selection of quarterly samples follows principles of the so-called rotation scheme according to which there are scheduled for the interview in a given quarter: two elementary samples2 surveyed in the previous quarter, one elementary sample introduced into the survey for the first time and one elementary sample that was not surveyed in the previous quarter and had been introduced into the survey exactly one year before.
As the result of this rotation system each elementary sample is used according to the 2-(2)-2 principle: two quarters in the survey, two quarters break, again two quarters in the survey and then out. The selection of the sample to the LFS survey is carried out according to the principles of the two-stage sampling. The first-stage sampling units are census units called census clusters (in urban areas) and census enumerations districts (in rural areas) stratified by voivodships and classes of localities. The second-stage sampling units are dwellings.
The selections of the first-stage sampling units and dwellings is carried out on the basis of the National Official Register Territorial Division of the Country, including, i.a. the list of territorial statistical units and the address register of dwellings aggregated in accordance with particular census clusters and census enumeration districts.
