Quarterly Labour Force Survey, September - November, 1998 : Local Area Data

The <i>Labour Force Survey</i> (LFS) has been carried out in the UK since 1973. From 1973 until 1983 the survey was carried out biennially, and from 1984 until 1991 it was conducted annually. In 1992 the quarterly LFS was introduced. For full background and methodological information users should refer to the main <i>Quarterly Labour Force Survey</i> (QLFS) series (held at the UK Data Archive (UKDA) under GN 33246).<br>
<br>
The <i>Local Area Data</i> series was produced quarterly alongside the main QLFS from 1992-2006, and included aggregated data on employment, economic activity and related subjects, covering Local Authority Districts (LADs), Training and Enterprise Councils (TECs), and their Scottish and Welsh equivalents. From 1992 until August 1997, the data covered Great Britain, and from September 1997 data from Northern Ireland were added. The <i>Local Area Data</i> were also available as an annual database between 1994-1995 and 1999-2000, for LADs at individual level, but these are no longer produced.<br>

<b>LFS move from seasonal to calendar quarters</b><br>
In accordance with EU regulations, the LFS moved from seasonal (spring, summer, autumn, winter) quarters to calendar quarters (January-March, April-June, July-September, October-December) in 2006. The last seasonal <i>Local Area Data</i> dataset issued was the <i>Quarterly Labour Force Survey, December 2005 - February, 2006: Local Area Data</i> (SN 5392), and the first calendar quarter dataset was the <i>Quarterly Labour Force Survey, January - March, 2006: Local Area Data</i> (SN 5393). Users should note that there is some overlap between these two datasets. Further information on the seasonal to calendar quarter change and its impact on LFS data may be found in the following online article:<br>

*劳动力调查（Labour Force Survey, LFS）*自1973年起在英国正式开展。1973年至1983年期间，该调查每两年开展一次；1984年至1991年调整为每年一次。1992年，季度劳动力调查正式推出。如需获取完整背景与方法论信息，用户可查阅主系列的*季度劳动力调查（Quarterly Labour Force Survey, QLFS）*数据集，该数据集由英国数据档案馆（UK Data Archive, UKDA）以GN 33246编号存档。

*地方区域数据（Local Area Data）*系列自1992年至2006年与主季度劳动力调查同步按季度发布，包含就业、经济活动及相关主题的汇总数据，覆盖范围包括地方行政区（Local Authority Districts, LADs）、培训与企业委员会（Training and Enterprise Councils, TECs）及其苏格兰、威尔士对应机构。1992年至1997年8月，该数据集仅涵盖大不列颠地区；1997年9月起，新增北爱尔兰地区的数据。1994-1995年及1999-2000年期间，地方区域数据还以地方行政区个体层面的年度数据库形式发布，但该类数据库现已停止更新。

**劳动力调查从季节季度切换为自然季度**
根据欧盟相关法规，劳动力调查于2006年从季节季度（春、夏、秋、冬）调整为自然季度（1-3月、4-6月、7-9月、10-12月）。最后一期发布的季节季度地方区域数据为*《2005年12月-2006年2月季度劳动力调查：地方区域数据》（编号SN 5392）*，首份自然季度数据集则为*《2006年1-3月季度劳动力调查：地方区域数据》（编号SN 5393）*。用户需注意，这两份数据集存在部分数据重叠。如需了解季节季度转自然季度的调整细节及其对劳动力调查数据的影响，可查阅以下在线文章：
