Annual Population Survey Two-Year Longitudinal Dataset, January 2020 - December 2021

<p>The <i>Annual Population Survey</i> (APS) is a major survey series, which aims to provide data that can produce reliable estimates at local authority level. Key topics covered in the survey include education, employment, health and ethnicity. The APS comprises key variables from the<a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000026"> </a><i><a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000026">Labour Force Survey</a></i> (LFS), all its associated LFS boosts and the APS boost.</p><p>The APS allows for analysis to be carried out on detailed subgroups and below regional level. In recent years (particularly with the sample size of the LFS 5 quarter dataset reducing) there has been some interest in producing a two year APS longitudinal dataset to look at any trends that may occur over a year. The APS Two-Year Longitudinal Datasets, covering 2012/13 onwards, have been deposited as a result of this work. <a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=200002#!/access-data">Person- and Household-level APS</a> datasets are also available.</p><p> </p><p>For further detailed information about methodology, users should consult the <i>Labour Force Survey User Guide</i>, included with the APS documentation.<br></p>

年度人口调查（Annual Population Survey，APS）是一项核心调查系列，旨在生成可用于地方当局层面的可靠估算数据。该调查涵盖教育、就业、健康与族裔等核心议题。APS整合了来自劳动力调查（Labour Force Survey，LFS）的关键变量、所有配套LFS补充样本及自身补充样本。
APS支持针对细分群体及区域以下层级开展分析。近年来，尤其是随着LFS五季度数据集样本量缩减，学界对构建两年期APS纵向数据集以观测年度内潜在趋势的需求日益增长。基于此项工作，2012/13年度及之后的APS两年期纵向数据集已完成归档入库，同时个人与家庭层面的APS数据集也可公开获取。
