CSEW
收藏资源简介:
<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. More information can be found in the 2017-18 User Guide (see SN 8464) and the article ‘<a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/articles/improvingvictimisationestimatesderivedfromthecrimesurveyforenglandandwales/2019-01-24">Improving victimisation estimates derived from the Crime Survey for England and Wales</a>’. </p> <p><span style="font-weight: bold;">Latest edition information</span></p><p>For the second edition (November 2020), the correct version of the 2018-2019 children non-victim form data has been deposited, previously the 2017-2018 data was made available.</p>
<p><span style="font-style:italic">英格兰及威尔士犯罪调查</span>(Crime Survey for England and Wales, CSEW)会从随机抽取的家庭样本中选取一名成年受访者,询问其本人或家庭在过去12个月内的犯罪受害经历,相关信息记录于<span style="font-style:italic">受害问卷数据集</span>(Victim Form, VF)中。后续问卷涵盖人口统计学信息与犯罪相关主题,例如对警方及<span style="font-style:italic">刑事司法系统</span>(Criminal Justice System, CJS)的态度等,这些变量存储于<span style="font-style:italic">非受害问卷数据集</span>(Non-Victim Form, NVF)内。2009年,该调查新增了针对10至15岁儿童的模块:从受访家庭中选取一名该年龄段的居民,询问其犯罪受害经历及其他相关话题。首批儿童调查数据覆盖2009年1月至12月,单独以编号SN 6601存储。自2009-2010调查年度起,儿童调查数据的覆盖周期与成人调查一致,并纳入主研究数据集。</p><p><span style="font-style:italic">电话调查版英格兰及威尔士犯罪调查</span>(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<span style="font-style:italic">新冠疫情</span>(coronavirus disease 2019, COVID-19)暂停的面对面版CSEW的替代方案,旨在评估疫情期间的犯罪水平。由于疫情贯穿2020/21调查年度,学界与实务界对2021年3月截止的TCSEW数据是否可与此前面对面版CSEW的估算结果进行比较提出了质疑。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">《电话调查版与面对面版英格兰及威尔士犯罪调查的可比性》</a>报告,剖析了可能影响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、问卷调整与调查模式变更。</p><p>更多关于CSEW的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">《英格兰及威尔士犯罪调查》</a>专题页面;而关于原<span style="font-style:italic">英国犯罪调查</span>(British Crime Survey, BCS)的相关信息,则可从英国政府官网(GOV.UK)的<a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology">《英国犯罪调查方法论》</a>页面获取。</p><p><span style="font-style:italic">历史沿革——英国犯罪调查</span></p><p>CSEW的前身为<span style="font-style:italic">英国犯罪调查</span>(BCS),自1981年起开展。1982年与1988年的BCS调查轮次亦在苏格兰进行,相关数据单独以编号SN 4368与SN 4599存储。自1993年起,英国单独开展<a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046">《苏格兰犯罪与司法调查》</a>。2001年以前,BCS为每两年一度的调查。自2001年4月起,英国国家统计局接管该调查并将其更名为CSEW,此后调查转为持续进行,并以财政年度为周期发布报告,犯罪调查的参考周期也随之调整以适配新的运行模式。</p><p> </p><p><em>安全访问版CSEW数据</em><br />除主调查外,成人受访者还需通过基于笔记本电脑的自填模块回答一系列问题,内容涵盖饮酒行为、药物使用、自伤行为、帮派问题、个人安全以及<span style="font-style:italic">亲密伴侣暴力</span>(Intimate Personal Violence, IPV,包括跟踪骚扰与性受害)等,各年度的问题可能存在调整。10至15岁的儿童亦需填写独立的自填问卷。上述问卷已纳入主调查文档,但相关数据仅可通过安全访问权限获取(详见编号SN 7280),不随主数据集一并发布。此外,自2011年起,低层级地理变量数据也需通过安全访问权限获取(详见编号SN 7311)。<br /><br /><span style="font-style:italic">2017-18年度起实施的事件数封顶新方法</span><br />2017-18年度及以后发布的CSEW数据集,采用了将事件数封顶至第98百分位数的新方法。虽然事件类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98百分位数封顶规则,而旧数据集未采用该规则,因此2012-2013年度以前的数据与后续数据已不再具有可比性。更多相关细节可查阅2017-18年度用户指南(详见编号SN 8464)以及文章《<a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/articles/improvingvictimisationestimatesderivedfromthecrimesurveyforenglandandwales/2019-01-24">优化英格兰及威尔士犯罪调查的受害估算结果</a>》。</p><p><span style="font-weight: bold;">最新版本说明</span></p><p>在2020年11月发布的第二版数据中,已正确更新了2018-2019年度儿童非受害问卷数据集,此前发布的为2017-2018年度的错误数据。</p>
