Crime Survey for England and Wales, 1996-2020: Secure Access

<i>Background</i>:<br> The <i>Crime Survey for England and Wales</i> (CSEW), previously known as the <i>British Crime Survey</i> (BCS), has been in existence since 1981. The survey traditionally asks a sole randomly selected adult, in a random sample of households, details pertaining to any instances where they, or the household, has been a victim of a crime in the previous 12 months. These are recorded in the victim form data file (VF). A wide range of questions are then asked covering demographics and crime-related subjects such as attitudes to the police and the criminal justice system (CJS). Most of the questionnaire is completed in a face-to-face interview in the respondent's home; these variables are contained within the non-victim form (NVF) data file. Since 2009, the survey has been extended to children aged 10-15 years old; one resident of that age range has also been selected at random from the household and asked about incidents where they have been a victim of crime, and other related topics. The first set of children's data, covering January-December 2009, had experimental status, and is held separately under SN 6601. From 2009-2010, the children's data cover the same period as the adult data and are included with the main dataset.

Children aged 10-15 years also complete a separate self-completion questionnaire. The questions are contained within the main questionnaire documents, but the data are not available with the main survey; they are available only under Secure Access conditions. Lower-level geographic variables are also available under Secure Access conditions to match to the survey.<br> <br> <i>History</i>:<br> Up to 2001, the survey was conducted biennially. From April 2001, interviewing was carried out continually and reported on in financial year cycles and the crime reference period was altered to accommodate this change. The core sample size has increased from around 11,000 in the earlier cycles to over 40,000. Following the National Statistician's Review of Crime Statistics in June 2011 the collation and publication of Crime Statistics moved to the Office for National Statistics (ONS) from 1st April 2012, and the survey changed its name to the <i>Crime Survey for England and Wales</i> (CSEW) accordingly.<br> <br> <i>Scottish data</i>:<br> The 1982 and 1988 BCS waves were also conducted in Scotland. The England and Wales data for 1982 and 1988 are held at the UKDA under SNs 1869 and 2706, but the Scottish data for these studies are held separately under SNs 4368 and 4599. Since 1993, separate <i>Scottish Crime and Justice Surveys</i> have been conducted, see the <a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046" target="_blank">series</a> web page for more details.<br><br><span style="font-style: italic;">New methodology for capping the number of incidents from 2017-18<br></span>The CSEW datasets available from 2017-18 onward are based upon a new methodology of capping the number of incidents at the 98th percentile. Incidence variables names have remained consistent with previously supplied data but due to the fact they are based on the new 98th percentile cap, and old data sets are not, comparability has been lost with previous years. More information can be found in the 2017-18 User Guide and the article ‘Improving victimisation estimates derived from the Crime Survey for England and Wales’. ONS intend to publish all micro data back to 1981 with incident data based on the 98th percentile cap later in 2019.<br> The main CSEW 1996-2020 Secure Access dataset (SN 7280) includes:<ul><li>the adult and child data also held in the standard End User Licence (EUL) version</li><li>adult self-completion modules on drinking behaviour, drug use, stolen goods, children's self-completion modules and sexual identity and low-level geography variables formerly held under Special Licence access conditions (please note that not all modules occur for each year - see the survey year's documentation for details)</li><li>hate crime variables HATEMT3A-HATEMT3I and HATEPS3A-HATEPS3I from the victim form</li><li>the interpersonal violence (IPV) data (comprising the modules on domestic violence, sexual victimisation and stalking)</li></ul>Users who do not require access to the modules noted above should apply for the EUL version. The Secure Access version has more restrictive access conditions than standard EUL version - see 'Access' section.

<i>背景</i>:<br>英格兰和威尔士犯罪调查（Crime Survey for England and Wales，CSEW）前身为英国犯罪调查（British Crime Survey，BCS），自1981年起实施。该调查传统上从随机抽样家庭中选取一名成人受访者，询问其本人或家庭过去12个月内遭受犯罪侵害的详细情况，相关信息记录在受害者表单数据文件（VF）中。随后会开展一系列涵盖人口统计学特征及犯罪相关主题的调查，例如对警方和刑事司法系统（criminal justice system，CJS）的态度。问卷主体通过受访者家中的面对面访谈完成，相关变量包含在非受害者表单（NVF）数据文件中。2009年起，调查范围扩展至10-15岁儿童：从家庭中随机选取该年龄段儿童，询问其遭受犯罪侵害的事件及其他相关主题。2009年1-12月的首套儿童数据为试验性数据，单独存于SN 6601编号下；2009-2010年起，儿童数据与成人数据调查周期一致，并纳入主数据集。更多信息可查阅英国国家统计局（ONS）的<a href="https://www.ons.gov.uk/surveys/informationforhouseholdsandindividuals/householdandindividualsurveys/crimesurveyforenglandandwales" title="Crime Survey for England and Wales" target="_blank">英格兰和威尔士犯罪调查</a>网页，此前BCS的信息可访问英国政府网站（GOV.UK）的<a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology" title="BCS Methodology" target="_blank">BCS方法论</a>网页。<br><br><i>自填数据</i>:<br>关于饮酒行为、毒品使用及亲密个人暴力（包括跟踪与性侵害）的一系列问题，通过受访者在笔记本电脑上完成的自填模块向成人发放；10-15岁儿童也需完成单独的自填问卷。这些问题包含在主问卷文档中，但数据不随主调查一同提供，仅在安全访问条件下可用。低级别地理变量同样需在安全访问条件下获取，以便与调查数据匹配。<br><br><i>历史沿革</i>:<br>截至2001年，该调查每两年开展一次；2001年4月起改为持续访谈，按财政年度周期报告，犯罪参考期也相应调整。核心样本量从早期约11000份增至40000余份。2011年6月国家统计师对犯罪统计数据审查后，犯罪统计的整理与发布于2012年4月1日移交给英国国家统计局（ONS），调查名称随之更改为CSEW。<br><br><i>苏格兰数据</i>:<br>1982年和1988年的BCS调查亦在苏格兰开展。英格兰和威尔士1982年、1988年的数据存于英国数据服务中心（UKDA）SN 1869和SN 2706编号下，同期苏格兰数据单独存于SN 4368和SN 4599编号下。1993年起苏格兰单独开展苏格兰犯罪与司法调查，详情见<a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046" target="_blank">系列</a>网页。<br><br><span style="font-style: italic;">2017-18年度事件数量上限设定新方法<br></span>2017-18年度及以后的CSEW数据集采用新方法，将事件数量上限设定在第98百分位。事件变量名称与此前数据保持一致，但因基于新的第98百分位上限（旧数据集未采用），与往年数据的可比性已丧失。更多信息可查阅2017-18年度用户指南及《改进英格兰和威尔士犯罪调查得出的受害估计》一文。ONS计划于2019年晚些时候发布1981年以来所有基于第98百分位上限的事件数据微观资料。<br>主要的CSEW 1996-2020安全访问数据集（SN 7280）包含：<ul><li>标准最终用户许可（End User Licence，EUL）版本中亦包含的成人和儿童数据</li><li>成人自填模块（涉及饮酒行为、毒品使用、赃物）、儿童自填模块、性身份及原需特殊许可访问的低级别地理变量（请注意并非每年包含所有模块，详情见各调查年度文档）</li><li>受害者表单中的仇恨犯罪变量HATEMT3A-HATEMT3I和HATEPS3A-HATEPS3I</li><li>人际暴力（interpersonal violence，IPV）数据（包含家庭暴力、性侵害及跟踪模块）</li></ul>无需访问上述模块的用户应申请EUL版本。安全访问版本的访问条件比标准EUL版本更严格——详见“访问”部分。该系列所有研究均可从<a href="http://discover.ukdataservice.ac.uk/series/?sn=200009" title="Crime Survey for England and Wales Series" target="_blank">CSEW</a>系列网页查看。<br><br>本研究还包含2008年以来的以下低级别地理变量：<ul><li>地方当局辖区</li><li>城乡区域分类</li><li>警察局辖区</li><li>ONS辖区级分类：超级组</li><li>ONS辖区级分类：组</li><li>ONS辖区级分类：子组</li><li>输出区域分类——超级组（7类）</li><li>输出区域分类——组（21类）</li><li>输出区域分类——子组（52类）</li></ul>包含下至下层超级输出区域变量的另一套CSEW低级别地理文件，可通过单独的安全访问研究SN 7311获取。<br><br><span style="font-weight: bold;">最新版本信息</span>:<br>第11版（2021年8月）中添加了CSEW 2019-2020年的数据和文档。<br><br>
