Labour Force Survey 2006 - Poland

Abstract
---------------------------

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 primary objective of the LFS is to obtain data on the size and structure of the labor force.
The results of the study will be used primarily to:
- Determining the balance of the workforce from three basic categories of the population: employed, unemployed and inactive,
- Analysis of changes in economic activity in different groups of socio-professional and cross-territorial
- Analysis of the situation on the labor market, including the assessment of the scale and extent of changes in the unemployment rate in spatial terms,
- Socio-demographic characteristics of the unemployed,
- Analysis of the structure of employment by socio-demographic characteristics and professional.

Geographic coverage

National coverage

Analysis unit
---------------------------

- Individual aged 15 and over

Universe
---------------------------

The LFS covers persons aged 15 and over who are the members of sampled households. The survey does not cover the members of households who stayed abroad above 2 months. Neither does it cover the population living in the collective households, such as lodging-houses for employees, student hostels, boarding-schools, army barracks, houses for the poor and the old, etc.

Sample survey data [ssd]

Sampling procedure
---------------------------

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Since the fourth quarter of 1999, the observation of the reference week in the middle month of a quarter has been replaced by the continuous observation method, which means that in each of the 13 weeks of a quarter 1/13th part of the quarterly sample of dwellings is surveyed.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.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

The Labour Force Survey is carried out with the use of two questionnaires:
• ZG Household File - assigned to each household recorded in the surveyed dwelling (ZG Files comprise household register during the entire survey cycle);

• ZD questionnaire, completed each quarter for every person aged 15 years and more present in the household or absent from the household; the ZD questionnaire includes questions concerning the respondent's current economic activity (i.e. the fact of performing work, being unemployed or economically inactive), occupational history, the methods of job search, as well as additional questions concerning, i.e. education and training.

摘要
---------------------------
本调查聚焦于从人口经济活动角度出发的情况，即参考周内就业、失业或经济不活跃的事实。
劳动力调查（LFS）的主要目标是获取关于劳动力规模和结构的数据。
研究结果的用途主要包括：
- 确定劳动力在三个基本人口类别（就业、失业和未就业）之间的平衡；
- 分析不同社会职业和跨地区群体中经济活动的变化；
- 分析劳动力市场状况，包括失业率在空间上的规模和范围变化评估；
- 失业者的社会人口特征；
- 分析按社会人口特征和职业划分的就业结构。
地理覆盖范围
---------------------------
全国范围
分析单元
---------------------------
- 15岁及以上的个人
总体
---------------------------
劳动力调查涵盖15岁及以上且为抽样家庭成员的个人。调查不包括在国外停留超过2个月的 household 成员。同样，也不包括居住在集体 household 中的人口，如员工宿舍、学生宿舍、寄宿学校、军营、穷人院和养老院等。
数据类型

样本调查数据 [ssd]
抽样程序
---------------------------
劳动力调查是一项概率样本调查。其结果被推广至总体。
自1999年第四季度以来，参考周（季度中间月份）的观察已由持续观察方法所取代，这意味着在每个季度的13周中，都会对季度样本住房的1/13进行调查。这允许展示整个季度劳动力市场的状况。
季度样本的选择遵循所谓的轮换方案，根据该方案，在给定季度内安排了以下访谈：前一个季度调查的两个基本样本，首次被纳入调查的一个基本样本，以及前一个季度未调查且恰好一年前被纳入调查的一个基本样本。由于这种轮换系统，每个基本样本都按照2-(2)-2原则使用：调查两个季度，休息两个季度，再次调查两个季度，然后退出。
LFS调查样本的选择遵循两阶段抽样的原则。第一阶段抽样单元是被称为人口普查单元的普查聚类（在城市地区）和按省份和地方类别分层的普查区（在农村地区）。第二阶段抽样单元是住房。第一阶段抽样单元和住房的选择基于国家官方登记的领土划分，包括，例如，领土统计单位清单和按特定普查聚类和普查区汇总的住房地址登记。

研究工具
---------------------------
劳动力调查使用两种问卷进行：
• ZG 家庭文件 - 分配给每个在调查住房中记录的家庭（ZG 文件包括在整个调查周期内的家庭登记）；
• ZD 问卷，每个季度为家庭中15岁及以上的人或不在家庭中的人完成；ZD 问卷包括关于受访者当前经济活动（即工作、失业或经济不活跃的事实）、职业历史、求职方法以及有关教育和技术等额外问题的内容。
