Quarterly Labour Force Survey, June - August, 1997 : 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》（LFS）自1973年起在英国开展。1973年至1983年期间，该调查每两年开展一次；1984年至1991年期间则为每年一次。1992年，季度劳动力调查推出。用户若需完整背景及方法学信息，应参考《季度劳动力调查》（QLFS）系列（由英国数据档案馆（UKDA）保管，编号为GN 33246）。<br><br>《区域数据》系列于1992年至2006年期间与主要QLFS同步按季度编制，包含就业、经济活动及相关主题的汇总数据，覆盖地方行政区（LADs）、培训与企业委员会（TECs）及其苏格兰和威尔士对应机构。1992年至1997年8月期间，数据覆盖大不列颠地区；1997年9月起，北爱尔兰数据被纳入。此外，1994-1995年至1999-2000年期间，《区域数据》还以年度数据库形式提供，包含地方行政区的个体层面数据，但该形式现已停止编制。<br><br>**劳动力调查从季节性季度向日历季度的转换**<br>根据欧盟法规，劳动力调查于2006年从季节性季度（春、夏、秋、冬）转换为日历季度（1-3月、4-6月、7-9月、10-12月）。最后一份季节性《区域数据》数据集为《2005年12月-2006年2月季度劳动力调查：区域数据》（SN 5392），首份日历季度数据集为《2006年1-3月季度劳动力调查：区域数据》（SN 5393）。用户需注意，这两份数据集存在部分重叠。关于季节性季度向日历季度转换及其对劳动力调查数据的影响，更多信息可参见以下在线文章：<br>Madouros, V.
