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Since the fourth quarter of 1999, the observation of the reference week in the middle month of a quarter has been replaced by the continuous observation method, which means that in each of the 13 weeks of a quarter 1/13th part of the quarterly sample of dwellings is surveyed.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现状，即参考周内就业、失业或经济不活跃的事实。
劳动力调查（LFS）的初级目标是为获取劳动力规模与结构的数据。
研究结果将主要用于以下目的：
- 确定劳动力在人口三个基本类别中的平衡：就业、失业和不活跃，
- 分析不同社会职业群体和跨地区经济活动变化，
- 分析劳动力市场状况，包括对失业率在空间维度上变化规模及程度的评估，
- 失业者的社会人口统计学特征，
- 分析按社会人口统计学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岁及以上个人
总体
劳动力调查涵盖15岁及以上且为样本家庭成员的个人。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 中的人群，如员工宿舍、学生宿舍、寄宿学校、军营、贫民窟和养老院等。

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。其结果适用于总体人口。
自1999年第四季度以来，季度中月份参考周的观测已由连续观测方法取代，这意味着在每季度的13周中，季度居住样本的1/13部分被调查。这允许在整个季度内呈现劳动力市场状况。
季度样本的选择遵循所谓的轮换方案，即在给定季度内安排进行访谈的有：前一季度调查的两个基本样本，首次引入调查的一个基本样本，以及前一季度未调查且正好一年前引入调查的一个基本样本。由于这种轮换系统，每个基本样本均按照2-(2)-2原则使用：在调查中两个季度，两个季度休止，再次在调查中两个季度，然后退出。
LFS调查样本的选择是根据两阶段抽样的原则进行的。第一阶段抽样单元是称为人口普查集群（在城区）的人口普查单元（在乡村地区）和按省和地区类别分层的人口普查区。第二阶段抽样单元是居住单元。第一阶段抽样单元和居住单元的选择基于国家官方注册领土划分，包括，例如，领土统计单位清单和根据特定人口普查集群和人口普查区汇总的居住单元地址登记簿。

研究工具
---------------------------
劳动力调查采用两种问卷进行：
• ZG 家庭文件 - 分配给每个记录在调查居住单元中的家庭（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岁及以上在户或在户外的人填写；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。
