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. 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><br></p>

<i>英格兰及威尔士犯罪调查</i>（Crime Survey for England and Wales, CSEW）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个月内遭遇犯罪侵害的经历，相关记录存储于被害人表单数据文件（Victim Form, VF）。随后将开展一系列涵盖人口统计特征与犯罪相关主题的调研，包括对警方及刑事司法系统（Criminal Justice System, CJS）的态度等，这些变量存储于非被害人表单数据文件（Non-Victim Form, NVF）。2009年，调查范围扩展至10至15岁儿童：从受访家庭中选取一名该年龄段居民，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，单独存储于编号SN 6601下。2009至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。

<i>英格兰及威尔士电话版犯罪调查</i>（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日因新型冠状病毒（COVID-19）疫情暂停的面对面版CSEW的替代方案，旨在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，有观点质疑2021年3月结束的TCSEW调查数据是否可与此前年度面对面版CSEW的估算结果相比较。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">英格兰及威尔士电话版犯罪调查与面对面版犯罪调查的可比性</a>》报告，探讨了可能影响TCSEW与原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。

更多关于CSEW的通用信息可查阅ONS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>页面；而此前的英国犯罪调查（British Crime Survey, BCS）相关信息可从GOV.UK官网的<a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology">BCS方法论</a>页面获取。

<i>历史沿革——英国犯罪调查</i>
CSEW前身为<i>英国犯罪调查</i>（British Crime Survey, BCS），自1981年起开展。1982年与1988年的BCS调查样本还涵盖苏格兰地区，相关数据单独存储于编号SN 4368与SN 4599下。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，并按财年周期发布报告，犯罪回顾周期也随之调整。

<i>安全访问版CSEW数据</i>
除主调查外，针对成年受访者还会通过基于笔记本电脑的自填模块，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）在内的问题（各年度的问题可能存在差异）。10至15岁的儿童也需填写单独的自填问卷。相关问卷已纳入主文档，但数据仅可通过安全访问权限获取（详见编号SN 7280），不随主研究数据集一并发布。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）。

<i>2017-18年度起实施的事件数封顶新方法</i>
2017-18年度及之后可获取的CSEW数据集，采用了将事件数封顶至第98百分位的新方法。尽管相关发生率变量的命名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年度之前的数据已无法与后续数据进行比较。更多相关信息可查阅2017-18年度用户指南（详见编号SN 8464）及文章《<a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/articles/improvingvictimisationestimatesderivedfromthecrimesurveyforenglandandwales/2019-01-24">优化英格兰及威尔士犯罪调查衍生的侵害估算结果</a>》。

背景与挑战

背景概述

CSEW（英格兰和威尔士犯罪调查）是一项长期进行的犯罪受害经历调查，覆盖随机抽样家庭中的成年人和儿童（自2009年起），数据分为受害者表单和非受害者表单，用于收集犯罪受害情况及相关人口统计和态度信息。数据集包括面对面和电话调查版本，并扩展至安全访问数据（如自我完成模块和地理变量），但自2017-18年起采用新方法（基于第98百分位数的事件上限），这可能影响与早期数据的可比性。
