CSEW

<i>2012-2013 self-completion modules</i>:<br> Data from the adult self-completion modules on drinking behaviour and drug use, the children's self-completion module and the low-level geographic variables, are held under Special Licence access conditions under SNs 7425, 7426, 7424 and 7423 respectively. The interpersonal violence data (comprising the module on domestic violence, sexual victimisation and stalking) are now available only under Secure Access conditions. See also 'Access' section below.<br> <br> <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 (see SN 7280). <br> <br> <i>Geographic variables</i>:<br> From 2008-2009, low-level geographic variables are available under Secure Access conditions to match to the survey/ From 2011-2012 onwards, further lower-level geographic variables are also available under Secure Access conditions.<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 46,000 up until 2011/12 where it was then reduced to 35,000. 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, and these are held under GN 33330.<br> <br>

**2012-2013年自我填报模块**：
关于饮酒行为与药物使用的成人自我填报模块数据、儿童自我填报模块数据，以及低级别地理变量数据，分别以专项许可访问条件存储，对应存档编号（SNs）7425、7426、7424与7423。包含家庭暴力、性受害与跟踪骚扰模块的人际暴力数据，目前仅可通过安全访问条件获取。详见下文“访问方式”章节。

**背景**：
《英格兰及威尔士犯罪调查》（Crime Survey for England and Wales, CSEW）前身为《英国犯罪调查》（British Crime Survey, BCS），自1981年起正式开展。传统调查流程为：在随机抽取的家庭中选取1名成年受访者，询问其本人或家庭在过去12个月内遭遇犯罪的相关细节，此类数据存储于**受害人表单数据集（Victim Form, VF）**。后续还会设置涵盖人口统计学特征与犯罪相关主题的大量问题，例如对警方及刑事司法系统（Criminal Justice System, CJS）的态度。大部分问卷内容通过受访者家中的面对面访谈完成，相关变量存储于**非受害人表单数据集（Non-Victim Form, NVF）**。
2009年起，调查范围扩展至10至15岁儿童：从受访家庭中随机选取1名该年龄段居民，询问其遭遇犯罪的经历及其他相关话题。2009年全年的首份儿童数据处于试验阶段，以存档编号SN 6601单独存储。2009-2010年度起，儿童数据与成人数据覆盖周期一致，并入主数据集。

**自我填报数据**
成年受访者将通过笔记本电脑完成自我填报模块，其中包含一系列关于饮酒行为、药物使用、自我伤害、帮派活动、个人安全，以及亲密伴侣暴力（Intimate Personal Violence, IPV，包含跟踪骚扰与性受害）的问题。10至15岁的儿童也需完成独立的自我填报问卷。相关问题收录于主问卷文档中，但数据并未随主调查公开，仅可通过安全访问条件获取（详见存档编号SN 7280）。

**地理变量**：
2008-2009年度起，低级别地理变量可通过安全访问条件获取，用于与调查数据匹配。2011-2012年度起，更多低级别地理变量也可通过安全访问条件获取。

**历史沿革**：
2001年之前，该调查每两年开展一次。2001年4月起，访谈改为持续进行，并以财政年度周期发布报告，同时调整犯罪参考周期以适配这一变更。核心样本量从早期的约11000份增至2011/12年度的46000余份，随后缩减至35000份。2011年6月国家统计师开展犯罪统计审查后，犯罪统计的整理与发布工作自2012年4月1日起移交至英国国家统计局（ONS），该调查也随之更名为《英格兰及威尔士犯罪调查》（CSEW）。

**苏格兰相关数据**：
1982年与1988年的BCS调查周期也在苏格兰开展。1982年与1988年的英格兰及威尔士数据以存档编号SN 1869与2706存储于英国数据档案馆（UK Data Archive, UKDA），但同期苏格兰数据则分别以存档编号SN 4368与4599单独存储。1993年起，苏格兰开展独立的《苏格兰犯罪与司法调查》，相关数据以存档编号GN 33330存储。

背景概述

该数据集是'英格兰和威尔士犯罪调查，2012-2013年'的第二版（2020年发布），由英国国家统计局制作，专注于犯罪相关数据。关键特点是采用了新的数据方法，即在第98百分位数上限制事件数量，这使得数据与2012-2013年之前的版本不可比，适用于研究犯罪趋势和统计方法更新。
