Understanding Society: Waves 1-13, 2009-2022: Special Licence Access, Census 2011 Output Area Classification

<span style="font-style: italic;">Understanding Society</span> (the UK Household Longitudinal Study), which began in 2009, is conducted by the Institute for Social and Economic Research (ISER) at the University of Essex, and the survey research organisations Kantar Public and NatCen. It builds on and incorporates, the British Household Panel Survey (BHPS), which began in 1991.
<p>This dataset contains Census 2011 Output Area Classification (OAC11) geographic variables for each wave of Understanding Society to date, and a household identification serial number for file matching to the main data.</p>
<p>These are the classifications for Output Areas and not the Output Area codes themselves. The lowest level of geography available under Special Licence is Lower Layer Super Output Areas (LSOA). There is also a 2001 census version of the Output Area Classifications: see SN 6674.</p>
<p>These data have more restrictive access conditions than those available under the standard End User Licence (see 'Access' section). Those users who wish to make an application for these data should contact the HelpDesk for further details.<br>
<br>
These data are consistent with the ONS Postcode Directory (ONSPD). Please see the Geographical Lookup Tables document for further details.<br>

*《理解社会》（Understanding Society，即英国住户纵向研究UK Household Longitudinal Study）于2009年启动，由埃塞克斯大学社会与经济研究所（Institute for Social and Economic Research, ISER）以及调研机构凯度公共（Kantar Public）与英国国家社会研究中心（NatCen）共同开展。该项目承接并整合了1991年启动的英国住户追踪调查（British Household Panel Survey, BHPS）。

本数据集包含截至当前各波次《理解社会》调研的2011年人口普查输出区域分类（Census 2011 Output Area Classification, OAC11）地理变量，以及用于与主数据集文件匹配的住户识别序列号。

此处提供的是输出区域的分类结果，而非输出区域编码本身。根据特殊许可可获取的最低层级地理单元为下层超级输出区域（Lower Layer Super Output Areas, LSOA）。另有2001年人口普查版的输出区域分类数据，详情请参阅编号SN 6674的数据集。

本数据集的访问限制条件严于标准最终用户许可协议相关要求（详见「访问」章节）。有意申请使用本数据集的用户，请联系服务支持台获取详细信息。

本数据集与英国国家统计局邮编目录（ONS Postcode Directory, ONSPD）保持一致，详细信息请参阅《地理匹配表》文档。
