description: &lt;p&gt;&lt;i&gt;Background&lt;/i&gt;:&lt;br&gt; The &lt;i&gt;Crime Survey for England and Wales&lt;/i&gt; (CSEW), previously known as the &lt;i&gt;British Crime Survey&lt;/i&gt; (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. Further information may be found on the ONS &lt;a href="https://www.ons.gov.uk/surveys/informationforhouseholdsandindividuals/householdandindividualsurveys/crimesurveyforenglandandwales" title="Crime Survey for England and Wales"&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" title="BCS Methodology"&gt;BCS Methodology&lt;/a&gt; web page.&lt;br&gt;&lt;i&gt;&lt;br&gt;Self-completion data&lt;br&gt;&lt;/i&gt;A series of questions on drinking behaviour, drug use, self-offending, gangs and personal security, and intimate personal violence (IPV) (including stalking and sexual victimisation) are administered to adults via a self-completion module which the respondent completes on a laptop computer. 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). &lt;br&gt;&lt;i&gt;&lt;br&gt;Geographic variables&lt;/i&gt;:&lt;br&gt;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.&lt;br&gt;&lt;i&gt;&lt;br&gt;History&lt;/i&gt;:&lt;br&gt;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 &lt;i&gt;Crime Survey for England and Wales&lt;/i&gt; (CSEW) accordingly.&lt;br&gt;&lt;i&gt;&lt;br&gt;Scottish data&lt;/i&gt;:&lt;br&gt;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 &lt;i&gt;Scottish Crime and Justice Surveys&lt;/i&gt; have been conducted, and these are held under GN 33330.&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;br&gt;&lt;/span&gt;The CSEW datasets available from 2017-18 onward are based upon 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 data sets are not, comparability has been lost with previous years. More information can be found in the 2017-18 User Guide and the article ‘Improving victimisation estimates derived from the Crime Survey for England and Wales’. ONS intend to publish all micro data back to 1981 with incident data based on the 98th percentile cap later in 2019.&lt;/p&gt; &lt;p&gt;For the fourth edition (January 2008), updated versions of the main non-victim form and victim form data files were deposited. These files incorporate amended weighting variables, in order to alleviate some previous confusion as to which weights to use. The original files included a number of weights compiled when two years were combined into one file; these have now either been removed or renamed correctly. The final weights that should be used are HHDWGT and INDIVWGT. The ethnic boost files will be reprocessed in the same way and redeposited in due course.&lt;/p&gt;&lt;p&gt;From October 2016, the self-completion modules on drugs and drinking behaviour are subject to Controlled data access conditions - see SN 7280.&lt;br&gt; &lt;/p&gt;
