Labour Force Survey, 1989

<P>Abstract copyright UK Data Service and data collection copyright owner.</P>The first <i>Labour Force Survey</i> (LFS) in the United Kingdom was conducted in 1973, under the terms of a Regulation derived from the Treaty of Rome. The provision of information for the Statistical Office of the European Communities (SOEC) continued to be one of the reasons for carrying out the survey on an annual basis. SOEC co-ordinated information from labour force surveys in the member states in order to assist the EC in such matters as the allocation of the Social Fund. The survey was carried out biennially from 1973 to 1983 and was increasingly used by UK government departments to obtain information which would assist in the framing of social and economic policy. By 1983 it was being used by the Employment Department (now the Department for Work and Pensions) to obtain information which was not available from other sources or was only available for Census years. From 1984 the survey was carried out annually, and since that time the LFS has consisted of two elements:<ul><li>a quarterly survey conducted in Great Britain throughout the year, in which each sampled address was called on five times at quarterly intervals, and which yielded about 15,000 responding households in every quarter</li><li>a `boost' survey in the spring quarter (March-May), which produced interviews at over 44,000 households in Great Britain and over 4,000 households in Northern Ireland</li></ul>Users should note that only the data from the spring quarter and the 'boost' survey were included in the annual datasets for public release, and that only data from 1975-1991 are available from the UK Data Archive. The depositor recommends only considered use of data for 1975 and 1977 (SNs 1757 and 1758), as the concepts behind the definitions of economic activity changed and are not comparable with later years. Also the survey methodology was being developed at the time and so the estimates may not be reliable enough to use.<br>
<br>
During 1991 the survey was developed, so that from spring 1992 the data were made available quarterly, with a quarterly sample size approximately equivalent to that of the previous annual data. The <i>Quarterly Labour Force Survey</i> series therefore superseded the annual LFS series, and is held at the Data Archive under GN 33246.<br>
<br><br>For the third edition of the study, the depositor supplied a re-weighted version of the data file. The re-weighting has been done to bring LFS data in line with the population estimates from the 2001 Census.<br><br><B>Main Topics</B>:<BR>The basic set of LFS questions sought information about household composition: i.e. for each usually resident individual member of the household, the relationship to the head of the household, sex, age, marital condition and nationality. For persons above the statutory school-leaving age information was sought about the main economic activity, any secondary economic activity, and economic activity one year previously. For unemployed persons questions were asked about the type of employment sought, duration of unemployment and method of seeking employment, previous employment status and industry and whether or not registered as unemployed at an official employment office.<br>

英国首次劳动力调查（Labour Force Survey, LFS）于1973年开展，其依据源自《罗马条约》的一项法规条款。为欧洲共同体统计办公室（Statistical Office of the European Communities, SOEC）提供数据，仍是该调查按年度开展的核心动因之一。SOEC协调各成员国劳动力调查的数据，以协助欧共体处理社会基金分配等事务。1973年至1983年间，该调查以两年为周期开展，英国政府各部门愈发依赖其获取的数据制定社会与经济政策。至1983年，就业部（现英国工作与养老金部（Department for Work and Pensions））已将其用于获取其他渠道无法获取、或仅在人口普查年份才能获得的数据。
1984年起，该调查转为年度开展，自此LFS包含两个组成部分：
其一，一项全年在大不列颠地区开展的季度调查：每一个抽中地址会按季度间隔被回访五次，每季度可回收约1.5万户有效问卷；
其二，春季季度（3月至5月）开展的“补充调查（boost survey）”：在大不列颠地区完成超4.4万户访谈，北爱尔兰地区完成超4000户访谈。

用户需注意，公开发布的年度数据集仅包含春季季度与补充调查的数据，且英国数据档案库仅提供1975年至1991年的相关数据。数据提交者建议仅使用1975年与1977年的数据（序列编号SN 1757与SN 1758），因为该阶段的经济活动定义概念发生了变化，与后续年份的数据不具有可比性。此外，该时期调查方法仍处于完善阶段，因此相关估算结果的可靠性不足以支撑正式使用。

1991年，该调查完成优化，自1992年春季起，数据改为按季度发布，单季度样本量大致等同于此前年度调查的总样本量。季度劳动力调查（Quarterly Labour Force Survey）系列自此取代了年度LFS系列，该系列数据由英国数据档案库以GN 33246编号存档。

本研究第三版中，数据提交者提供了经重新加权处理的数据文件。此次重加权旨在使LFS数据与2001年人口普查的人口估算结果保持一致。

【核心主题】：LFS的基础问卷模块旨在收集家庭构成相关信息，具体包括：家庭内每一位常住成员与户主的亲属关系、性别、年龄、婚姻状况及国籍。对于达到法定离校年龄的人群，问卷会收集其主要经济活动、次要经济活动以及一年前的经济活动状况。针对失业人群，问卷则会询问其求职类型、失业时长、求职渠道、此前就业状态与所属行业，以及是否在官方就业办公室登记失业。
