English House Condition Survey, 2001: Derived Data

The <i>English House Condition Survey</i> (EHCS) was a national survey of housing in England, commissioned by the Department for Communities and Local Government (DCLG). The survey was originally called the <i>National House Condition Survey</i> and covered England and Wales. The information obtained through the survey provides an accurate picture of the type, condition and energy efficiency of housing in England, the people living there, and their views on housing and their neighbourhoods. The survey covers all tenure types.<br>
<br>
The EHCS ran quinquennially from 1967-2001. From 2002, the survey moved to a continuous basis and the data were provided as a two-year rolling sample of approximately 16,000 cases (i.e. the data for 2003 cover information collected from April 2002 to March 2004, data for 2004 comprise information collected from April 2003 to March 2005). From April 2008, the EHCS merged with the <i>Survey of English Housing</i> (SEH) (available at the UK Data Archive under GN 33277) to form the <i>English Housing Survey</i> (EHS) (available at the Archive under GN 33422).<br>

<i>EHCS, 2001: Derived Data</i> contains just the derived data files but these can be used in conjunction with the continuous survey data for time series analysis (available from the UKDA under SNs 6101, 6103-6106).<br>
<br>
For the second edition (March 2016), a new variable, SAP12, was added to the physical file, to reflect updated methodology for calculating Standard Assessment Procedure (SAP) energy performance assessments.<br>

《英国住宅状况调查（English House Condition Survey，EHCS）》是一项由社区与地方政府部（Department for Communities and Local Government，DCLG）委托开展的英格兰全国住房调查。该调查最初名为《全国住宅状况调查（National House Condition Survey）》，调查范围覆盖英格兰与威尔士。本次调查获取的信息能够精准呈现英格兰住房的类型、状况与能源效率，居住人群的相关情况，以及居民对住房与社区的看法。该调查涵盖所有住房保有类型。

EHCS于1967年至2001年间每五年开展一次。自2002年起，该调查转为常态化运行，数据以约16000个样本的两年滚动抽样形式发布（例如2003年数据涵盖2002年4月至2004年3月期间收集的信息，2004年数据涵盖2003年4月至2005年3月期间收集的信息）。2008年4月起，EHCS与《英格兰住房调查（Survey of English Housing，SEH）》（可在英国数据档案馆（UK Data Archive）以编号GN 33277获取）合并，形成《英国住房调查（English Housing Survey，EHS）》（可在该档案馆以编号GN 33422获取）。

《2001年EHCS：衍生数据集》仅包含衍生数据集文件，但可与常态化调查数据结合用于时间序列分析（可通过英国数据档案馆（UKDA）以编号SN 6101、6103至6106获取该常态化调查数据）。

2016年3月发布的第二版中，实体文件新增了SAP12变量，以适配更新后的标准评估程序（Standard Assessment Procedure，SAP）能源绩效评估计算方法。
