The Crime Survey for England and Wales

Data from the Crime Survey for England and Wales (CSEW) continue to be badged as National Statistics.

The CSEW is a face-to-face survey in which people resident in households in England and Wales are asked about their experiences of crime in the 12 months prior to the interview. The overall target sample size for the survey in the year ending March 2014 was 35,000 households.

In the year ending March 2014, the CSEW had achieved a nationally representative sample of 34,906 adults and 2,902 children with response rates of 75% and 68% respectively. The survey is weighted to adjust for possible non-response bias and to ensure the sample reflects the profile of the general population. Being based on a sample survey, CSEW estimates are subject to a margin of error. Unless stated otherwise, all changes in CSEW estimates described in the main text are statistically significant at the 95 per cent level. For more information on statistical significance and confidence intervals for CSEW data, see Section 8 of the User Guide to Crime Statistics for England and Wales (ONS, 2015).

There have been some minor changes to the classifications of CSEW offences, in order to improve coherence of categories and to more closely align them with the presentation of police crime recorded offences. A programme of work to implement these has now been completed and bulletins referring to the year ending March 2014 onwards include these revised CSEW classifications (including a full reclassified back series to 1981).

These new CSEW classifications do not change the overall number of offences estimated by the survey, just the categories in which they are presented. As part of these the offence category of robbery has been moved out of CSEW ‘Violence’ into a separate standalone category. Further detail on the changes made to the presentation of CSEW statistics can be found in the methodological note ‘ Presentational and methodological improvements to National Statistics on the Crime Survey for England and Wales’ (176.2 Kb Pdf) .

Alongside these classification changes, an additional piece of survey development work was also implemented to produce revised survey weights and a back-series following the release of the 2011 Census-based population estimates. The programme of work to produce the revised weights and key estimates for all survey years back to 2001/02 is now complete and both CSEW and police recorded crime use post 2011 Census population figures. See the methodological note ‘ Presentational and methodological improvements to National Statistics on the Crime Survey for England and Wales (176.2 Kb Pdf) ’ for more information.
