Crime Survey for England and Wales

The Crime Survey for England and Wales (CSEW) (previously called the British Crime Survey) is a systematic victim study established in 1982 (with data from 1981). It is currently carried out by Verian (formally known as Kantar Public) on behalf of the Office for National Statistics (ONS) and curated by the UK Data Service. The survey is comparable to the National Crime Victimization Survey conducted in the United States.

The CSEW seeks to measure the amount of crime, as well as victims' experiece of it, in England and Wales by face-to-face surveys of around 31,000 people aged 16 or over, and 1,500 children aged 10 to 15 years. The survey only covers those living in private households.

The Children's Crime Survey for England and Wales (CCSEW) was established in January 2009 when the main survey was expanded to include interviews with children aged 10 to 15. This was further expanded in 2023 to include more information on child victimisation.

The CSEW is one of two main sources of crime statistics in the UK, providing a parallel measure to police-recorded crime (PRC) stastistics. While the surveys have been criticised for methodological deficiencies, the Office for National Statistics (ONS) regards the CSEW as the most reliable source of long-term trends in crime. However, due to the low sample rate for less common (particularly violent) crimes, the ONS supplements its published statistics on these with police-reported crime figures.
