CSEW

<p>The <span style="font-style:italic">Crime Survey for England and Wales</span> (CSEW) asks a sole adult in a random sample of households about their, or their household's, experience of crime victimisation 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). These variables are contained within the non-victim form (NVF) data file. In 2009, the survey was extended to children aged 10-15 years old; one resident of that age range was also selected from the household and asked about their experience of crime and other related topics. The first set of children's data covered January-December 2009 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 study.</p><p>The <span style="font-style:italic">Telephone-operated Crime Survey for England and Wales </span>(TCSEW) became operational on 20 May 2020. It was a replacement for the face-to-face CSEW, which was suspended on 17 March 2020 because of the coronavirus (COVID-19) pandemic. It was set up with the intention of measuring the level of crime during the pandemic. As the pandemic continued throughout the 2020/21 survey year, questions have been raised as to whether the year ending March 2021 TCSEW is comparable with estimates produced in earlier years by the face-to-face CSEW. The ONS <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/methodologies/comparabilitybetweenthetelephoneoperatedcrimesurveyforenglandandwalesandthefacetofacecrimesurveyforenglandandwales">Comparability between the Telephone-operated Crime Survey for England and Wales and the face-to-face Crime Survey for England and Wales</a> report explores those factors that may have a bearing on the comparability of estimates between the TCSEW and the former CSEW. These include survey design, sample design, questionnaire changes and modal changes.</p><p>More general information about the CSEW may be found on the ONS <a href="https://www.ons.gov.uk/surveys/informationforhouseholdsandindividuals/householdandindividualsurveys/crimesurveyforenglandandwales">Crime Survey for England and Wales</a> web page and for the previous BCS, from the GOV.UK <a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology">BCS Methodology</a> web page.</p><p><span style="font-style:italic">History - the British Crime Survey</span></p><p>The CSEW was formerly known as the <span style="font-style:italic">British Crime Survey</span> (BCS), and has been in existence since 1981. The 1982 and 1988 BCS waves were also conducted in Scotland (data held separately under SNs 4368 and 4599). Since 1993, separate <a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046">Scottish Crime and Justice Surveys</a> have been conducted. Up to 2001, the BCS was conducted biennially. From April 2001, the Office for National Statistics took over the survey and it became the CSEW. Interviewing was then carried out continually and reported on in financial year cycles. The crime reference period was altered to accommodate this. <br /></p><p> </p><p><em>Secure Access CSEW data<br /></em>In addition to the main survey, a series of questions covering drinking behaviour, drug use, self-offending, gangs and personal security, and intimate personal violence (IPV) (including stalking and sexual victimisation) are asked of adults via a laptop-based self-completion module (questions may vary over the years). Children aged 10-15 years also complete a separate self-completion questionnaire. The questionnaires are included in the main documentation, but the data are only available under Secure Access conditions (see SN 7280), not with the main study. In addition, from 2011 onwards, lower-level geographic variables are also available under Secure Access conditions (see SN 7311).<br /><br /><span style="font-style:italic">New methodology for capping the number of incidents from 2017-18</span><br />The CSEW datasets available from 2017-18 onwards are based on 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 datasets are not, comparability has been lost with years prior to 2012-2013.

<p>英格兰与威尔士犯罪调查（Crime Survey for England and Wales，CSEW）会从随机抽取的家庭中选取一名成年受访者，询问其本人或其家庭在过去12个月内遭遇犯罪侵害的经历。相关数据记录于被害人记录表数据文件（Victim Form，VF）中。随后调查会涵盖一系列广泛的问题，内容涉及人口统计学特征以及与犯罪相关的主题，例如对警方及刑事司法系统（Criminal Justice System，CJS）的态度，这类变量被收纳于非被害人记录表数据文件（Non-Victim Form，NVF）中。2009年，调查范围扩展至10至15岁的儿童：研究人员会从家庭中选取一名该年龄段的常住居民，询问其遭遇犯罪及其他相关议题的经历。首批儿童调查数据覆盖2009年1月至12月，单独以研究编号（Serial Number，SN）6601存储。2009-2010年度起，儿童调查数据与成人调查数据周期保持一致，并纳入主研究数据集。</p><p>电话版英格兰与威尔士犯罪调查（Telephone-operated Crime Survey for England and Wales，TCSEW）于2020年5月20日正式启用，作为2020年3月17日因新冠病毒（COVID-19）疫情暂停的面对面版CSEW的替代方案，其设立初衷是衡量疫情期间的犯罪水平。由于疫情在2020/21调查年度持续蔓延，有质疑声指出，2021年3月结束的TCSEW调查数据，与此前年度面对面版CSEW生成的估算结果是否具有可比性。英国国家统计局（Office for National Statistics，ONS）发布的《<a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/methodologies/comparabilitybetweenthetelephoneoperatedcrimesurveyforenglandandwalesandthefacetofacecrimesurveyforenglandandwales">电话版与面对面版英格兰与威尔士犯罪调查的可比性</a>》报告，探讨了可能影响TCSEW与原面对面版CSEW估算结果可比性的各类因素，包括调查设计、抽样设计、问卷调整及调查模式变更。</p><p>关于CSEW的更多通用信息，可查阅英国国家统计局官网的<a href="https://www.ons.gov.uk/surveys/informationforhouseholdsandindividuals/householdandindividualsurveys/crimesurveyforenglandandwales">英格兰与威尔士犯罪调查</a>页面；而关于此前的英国犯罪调查（British Crime Survey，BCS），相关信息可从英国政府官网的<a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology">BCS方法论</a>页面获取。</p><p><span style="font-style:italic">历史——英国犯罪调查</span></p><p>CSEW前身为英国犯罪调查（British Crime Survey，BCS），自1981年起开展。1982年与1988年的BCS调查还在苏格兰地区实施（相关数据以研究编号SN 4368与SN 4599单独存储）。1993年起，苏格兰地区开始开展独立的<a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046">苏格兰犯罪与司法调查</a>。2001年之前，BCS每两年开展一次。2001年4月起，由英国国家统计局接手该调查，并更名为CSEW，此后调查持续开展，并按财政年度周期发布报告，犯罪调查的参考周期也随之调整。</p><p> </p><p><em>安全访问版CSEW数据</em><br />除主调查外，研究人员会通过基于笔记本电脑的自填模块，向成年受访者询问一系列涵盖饮酒行为、药物使用、自伤行为、帮派问题、个人安全以及亲密伴侣暴力（Intimate Personal Violence，IPV，包括跟踪骚扰与性侵害）的问题（各年度的问卷题目可能存在差异）。10至15岁的儿童也需填写独立的自填问卷。问卷内容已纳入主调查文档，但相关数据仅可通过安全访问渠道获取（详见研究编号SN 7280），不随主研究数据集一同发布。此外，自2011年起，低层级地理变量数据也仅可通过安全访问渠道获取（详见研究编号SN 7311）。<br /><br /><span style="font-style:italic">2017-18年度起实施的事件数量封顶新方法</span><br />2017-18年度及之后发布的CSEW数据集，采用了将事件数量封顶至第98百分位的新方法论。尽管事件相关变量的名称与此前发布的数据保持一致，但由于新数据集基于第98百分位封顶规则，而旧数据集未采用该规则，因此2012-2013年度之前的数据已不再具备可比性。更多相关信息可查阅2017-18年度用户指南（详见研究编号SN 8464）及文章《<a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/articles/improvingvictimisationestimatesderivedfromthecrimesurveyforenglandandwales/2019-01-24">优化英格兰与威尔士犯罪调查的侵害估算结果</a>》。</p><p><span style="color: rgb(51, 51, 51); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 13px; font-style: italic; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">最新版本</span><span style="font-style: italic;">信息</span><br>2020年3月发布的第三版数据，采用了将事件数量封顶至第98百分位的新方法论。尽管事件相关变量的名称与此前发布的数据保持一致，但由于新数据集基于第98百分位封顶规则，而旧数据集未采用该规则，因此2012-2013年度之前的数据已不再具备可比性。更多相关信息可查阅伴随2017-2018年度CSEW研究发布的<a href="http://doc.ukdataservice.ac.uk/doc/8464/mrdoc/pdf/8464_2017-18_csew_adults_dataset_user_guide.pdf" target="_blank" style="background-color: rgb(255, 255, 255);">用户指南</a>，该研究以研究编号<a href="https://beta.ukdataservice.ac.uk/datacatalogue/studies/study?id=8464" target="_blank" style="background-color: rgb(255, 255, 255);">SN 8464</a>存储。</p>
