description: &lt;p&gt;The &lt;span style="font-style:italic"&gt;Crime Survey for England and Wales&lt;/span&gt; (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.&lt;/p&gt;&lt;p&gt;The &lt;span style="font-style:italic"&gt;Telephone-operated Crime Survey for England and Wales &lt;/span&gt;(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 &lt;a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/methodologies/comparabilitybetweenthetelephoneoperatedcrimesurveyforenglandandwalesandthefacetofacecrimesurveyforenglandandwales"&gt;Comparability between the Telephone-operated Crime Survey for England and Wales and the face-to-face Crime Survey for England and Wales&lt;/a&gt; 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.&lt;/p&gt;&lt;p&gt;More general information about the CSEW may be found on the ONS &lt;a href="https://www.ons.gov.uk/surveys/informationforhouseholdsandindividuals/householdandindividualsurveys/crimesurveyforenglandandwales"&gt;Crime Survey for England and Wales&lt;/a&gt; web page and for the previous BCS, from the GOV.UK &lt;a href="https://www.gov.uk/government/statistics/british-crime-survey-methodology"&gt;BCS Methodology&lt;/a&gt; web page.&lt;/p&gt;&lt;p&gt;&lt;span style="font-style:italic"&gt;History - the British Crime Survey&lt;/span&gt;&lt;/p&gt;&lt;p&gt;The CSEW was formerly known as the &lt;span style="font-style:italic"&gt;British Crime Survey&lt;/span&gt; (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 &lt;a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000046"&gt;Scottish Crime and Justice Surveys&lt;/a&gt; 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. &lt;br /&gt;&lt;/p&gt;&lt;p&gt;


&lt;/p&gt;&lt;p&gt;&lt;em&gt;Secure Access CSEW data&lt;br /&gt;&lt;/em&gt;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).&lt;br /&gt;&lt;br /&gt;&lt;span style="font-style:italic"&gt;New methodology for capping the number of incidents from 2017-18&lt;/span&gt;&lt;br /&gt;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 ‘&lt;a href="https://www.ons.gov.uk/peoplepopulationandcommunity/crimeandjustice/articles/improvingvictimisationestimatesderivedfromthecrimesurveyforenglandandwales/2019-01-24"&gt;Improving victimisation estimates derived from the Crime Survey for England and Wales&lt;/a&gt;’. &lt;/p&gt; &lt;i&gt;Extending the BCS to Children&lt;/i&gt;&lt;br&gt;
Following the 'Smith Review', &lt;a href="http://www.homeoffice.gov.uk/rds/pdfs06/crime-statistics-independent-review-06.pdf" title="Crime statistics: an independent review"&gt;'Crime statistics: an independent review'&lt;/a&gt;, the BCS has included children aged 10-15 years, through screening at sampled addresses. The &lt;i&gt;British Crime Survey Experimental Data: Children Aged 10-15 Years, January-December, 2009&lt;/i&gt; comprises the first set of BCS children's data to become available.&lt;br&gt;
&lt;br&gt;
The primary aim of extending the BCS to children is to provide estimates of the levels of crime experienced by children and their risk of victimisation. In addition to questions about experience of crime, the BCS children's survey also gathers information on a number of crime-related topics such as perceptions and attitudes to the police, anti-social behaviour, crime prevention and personal security. It is therefore envisaged that the BCS children's survey will also provide a rich source of data to assist in understanding the nature and circumstances of crimes experienced by children aged 10 to 15 years.&lt;br&gt;
&lt;br&gt;
Estimates published based on these data have been published as 'Experimental Statistics'. In accordance with the Code of Practice for Official Statistics, 'Experimental Statistics' are new official statistics undergoing evaluation and published to involve users and stakeholders in their development as a means to build in quality at an early stage. As such, these data are subject to future revision and change.&lt;br&gt;
&lt;br&gt;
&lt;i&gt;Comparing the children's data with the adult BCS&lt;/i&gt;&lt;br&gt;
The BCS children's experimental dataset has been developed as an extension to the existing adult BCS to children aged 10 to 15 years. However, methodological differences between the adult and child BCS mean that direct comparisons cannot be made between the adult and child data. That said, while the questions asked and levels of detail collected differ between the data sources there is a common approach to the classification of incidents to offences in law. For further details of the methodology, see documentation.&lt;br&gt;
