Data Sources

The CSEW

The Crime Survey for England and Wales (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. In the year ending March 2012, the CSEW had a nationally representative sample of 46,031 adults and 3,930 children with response rates of 75% and 67% 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, 2013).

CSEW 10 to 15 year olds

Since January 2009, the Crime Survey for England and Wales (CSEW) has asked children aged 10 to 15 resident in households in England and Wales about their experience of crime in the previous 12 months. Methodological differences mean that direct comparisons cannot be made between the adult and child data (Crime in England and Wales, 2009/10).

Police recorded crime

Police recorded crime is the primary source of sub-national crime statistics and lower-volume crimes. It covers people (for example residents of institutions and tourists) and sectors (for example commercial crime) excluded from the Crime Survey for England and Wales (CSEW) sample, and has a wider coverage of offences - for example fraud and some crimes against businesses. Police recorded crime also covers some types of serious but relatively less common offences that are not covered or are less well covered by the survey, including robbery.

Police recorded crime statistics are affected by changes in reporting and recording practices. To ensure consistency, police recording practice is governed by Home Office Counting Rules (HOCR) and the National Crime Recording Standard (NCRS). These rules provide a national standard for the recording and classifying of notifiable offences by police forces in England and Wales (see Home Office, 2011).

There have been two major changes to the recording of crimes in recent years: in April 1998 the HOCR for recorded crime were expanded to include certain additional summary offences and counts became more victim-based (the number of victims was counted rather than the number of offences); in April 2002, the NCRS was introduced across England and Wales, although some forces adopted key elements of the standard earlier and compliance with the standard continued to improve in the years following its formal introduction. The NCRS was devised by the Association of Chief Police Officers (ACPO) in collaboration with Home Office statisticians. It was designed to ensure greater consistency between forces in recording crime and to take a more victim-oriented approach to crime recording with the police being required to record any allegation of crime unless there was credible evidence to the contrary (Simmons et al., 2003).

Both these changes resulted in an increase in the number of crimes recorded. Certain offences, such as the more minor violent crimes, were more affected by these changes than others. All of these factors need to be considered when looking at the trends in recorded crime. For these reasons, statistical bulletins present trends following the introduction of recording changes in police recorded crime from 2002/03. For more information see Chapter 3 of the User Guide.

2012 Commercial Victimisation Survey

The Commercial Victimisation Survey (CVS) provides information on the volume and type of crime committed against businesses in England and Wales by sector. This was launched following a recommendation of the National Statistician’s review of crime statistics (National Statistician, 2011).

The CVS is a telephone victimisation survey in which businesses in England and Wales are asked about their experiences of a range of crimes in the 12 months prior to interview. A total of 4,017 businesses from the manufacturing, retail and wholesale, transport and storage and accommodation and food sectors were interviewed in the 2012 CVS (approximately 1,000 from each sector). The survey uses similar methodology and questions to two previous surveys carried out in 1994 and 2002 allowing some comparisons to be made, notably for the retail sector. More information on the methodology of the survey is included in the Home Office’s report Crimes against businesses: headline findings from the 2012 Commercial Victimisation Survey.

Robbery

As the Crime Survey for England and Wales (CSEW) is a sample survey, relatively few victims of less frequently occurring crimes are interviewed and these figures are therefore subject to greater fluctuations between years. These offences are better represented within police recorded crime figures, though they are still subject to the aforementioned limitations and will only include those offences that come to the attention of the police.
