Important points about the Domestic abuse in England and Wales data
The publication on Domestic abuse in England and Wales: year ending March 2018 includes data covering the different stages of the criminal justice process for cases of domestic abuse and brings together a selection of data on service provision for victims of domestic abuse.
The publication brings together several different data sources to provide a more coherent picture of domestic abuse, but it is not possible to directly compare each of the different datasets due to differences in the timescales and reference periods used to collect the data and because they do not all count the same thing.
Throughout the publication, cautions are provided to make it clear where a comparison can be made and where it may be more difficult or not possible to directly compare data sources.
Data from the Crime Survey for England and Wales, the Home Office Homicide Index and the Ministry of Justice are classified as National Statistics.
Due to concerns over the quality and consistency of crime recording practice, police recorded crime data were assessed against the Code of Practice for Statistics and found not to meet the required standard for designation as National Statistics1. Therefore, police recorded crime and outcomes data from the Home Office are classified as official statistics.
All other data included in the publication are sourced from administrative datasets that do not fall within the scope of official statistics.
Notes on: Important points

Overview of the Domestic abuse in England and Wales data
The publication on Domestic abuse in England and Wales: year ending March 2018 has been produced in response to a recommendation made by Her Majesty’s Inspectorate of Constabulary and Fire and Rescue Services (HMICFRS) in their 2015 progress report (PDF, 1.5MB) on the police response to domestic abuse that organisations should work together to:
“…develop a data set relating to domestic abuse which will enable more thorough analysis of how domestic abuse is dealt with in a force area.”
The aim of the publication is to bring together data on domestic abuse to enable appropriate action to be taken to improve victims’ experiences of the criminal justice process and to encourage more victims to come forward to report abuse, knowing that there is appropriate support available for them. It also provides a clearer understanding of the criminal justice system’s response to perpetrators of domestic abuse.
The statistics presented in the publication have been published as the third phase of this project, expanding on the data included in the first and second phase, which were released in December 2016 and November 2017 respectively. Additional information will continue to be added in future phases of the project to further increase the scope of the data available and create a more comprehensive resource for users.
The way in which data on domestic abuse are collected differs between sources and organisations. Data are collected over different timescales. Data can be based on offences, victims, suspects or defendants and can also vary in the way that cases are identified. These factors, together with the time lag between the stages in the criminal justice process, mean that each section in the publication does not refer to the same cohort of cases and so direct comparisons cannot be made across sections. For example, a case reported to the police in one year may not appear with an outcome after investigation until the next year, or a case with a prosecution outcome in one year may have been initially reported to the police in a previous year. Throughout the publication, cautions are provided to make it clear where a comparison can be made and where it may be more difficult or not possible to directly compare data sources.
For Crime Survey for England and Wales data and police recorded crime data, the Crime Statistics Quality and Methodology Information report contains important information on:
- the strengths and limitations of the data and how it compares with related data
- uses and users of the data
- how the output was created
- the quality of the output including the accuracy of the data
Uses and users of the Domestic abuse in England and Wales data
Data on Domestic abuse in England and Wales promotes significant interest from a range of users. These include elected national and local representatives (such as MPs, Police and Crime Commissioners and local councillors), Home Office and other government agencies, police forces, those delivering support or services to victims of crime, lobby groups, journalists, academic researchers, teachers and students.
The data can be used for a variety of purposes, including the development and monitoring of crime and justice policy, public safety campaigns, raising awareness of particular forms of crime and academic research. They also help to ensure that information on trends in domestic abuse offences in England and Wales are available to help inform the choices and decisions of the general public. Providing breakdowns of victim characteristics allow a greater depth of understanding about domestic abuse.
Table 1 shows the main user groups of domestic abuse statistics and how they use the data provided. The column on the left lists the classes of use identified by the UK Statistics Authority in their monitoring brief, The Use Made of Official Statistics (PDF, 125.6KB). The right column provides more detail on how the data fits that class of use.
|Informing the general public’s choices||Level of crime in England and Wales: the measures published provide insight into the levels and trends of domestic abuse, as well as the number of domestic abuse-related crimes recorded by the police, in England and Wales.|
Further breakdowns, such as by abuse type, region, and characteristics of victims, allow a greater depth of understanding about domestic abuse.
|Number of crimes recorded: the number of domestic abuse-related crimes recorded by the police is another important measure of crime. This information can help the public in holding elected representatives to account and in making choices about who they will vote for.|
|Keeping safe: bringing together data on domestic abuse covering the different stages of the criminal justice system and service provision for victims can help encourage more victims to come forward to report abuse, knowing that there is appropriate support available for them.|
|Decision making about policies, programmes and projects||Policy making: data on domestic abuse-related crimes are important in informing government policy making to improve victim’s experiences of the criminal justice process – for example, new legislation to account for coercive and controlling behaviour.|
|Policy monitoring: such data allow the effectiveness of implemented policies relating to crime to be monitored and measured over a period of time.|
|Resource allocation||Public sector: data can be used to help determine the allocation of government resources to several organisations. For example, police forces might get more or less funding based on the number of crimes reported in respective police force areas and grants given to charities based on crime statistics, such as victim support groups.|
|Informing public marketing campaigns||Uptake of new police campaigns on domestic abuse. For example, in 2018 some police forces launched campaigns to coincide with the commencement of the football world cup. In autumn 2018 Cheshire launched with partners the Open The Door¹ campaign to raise awareness and promote conversations around domestic abuse.|
|Safety and awareness campaigns: these data can be used to support campaigns that aim to raise awareness of important issues, for example, sexual assault or domestic violence.|
|Supporting third sector activity||Lobbying: a range of lobby groups use crime statistics to help raise awareness of issues, such as variations in victimisation by socio-demographic characteristics such as age and sex.|
|Funding applications: organisations can use crime statistics to bid for funding for projects that aim to raise awareness of and tackle crime problems.|
|Facilitating academic research||Both the CSEW and police recorded crime are core sets of data on the levels and trends of domestic abuse in England and Wales. The annual CSEW dataset is also available as microdata as part of the UK Data Service. As a result, these data are widely used by academics studying topics in this area.|

Strengths and limitations of the Domestic abuse in England and Wales publication
The publication is produced annually and provides timely data to users.
The publication brings together data on domestic abuse in England and Wales to enable action to be taken to improve victims’ experiences of the criminal justice process and to encourage more victims to come forward to report abuse, knowing that there is appropriate support available for them.
The data provides a clearer understanding of the criminal justice system’s response to perpetrators of domestic abuse.
The domestic abuse data tool which is published alongside the report allows users to explore data for police force areas in more detail and compare these with similar areas within England and Wales.
The different datasets included in the publication do not relate to the same cases given the different timescales and reference periods used to collect the data, they also do not count the same things; for example, some record the number of victims or defendants, whilst others record the number of incidents or offences that occurred; therefore, each of the numbers cannot be directly compared.
Statistics on domestic abuse are produced separately by several different organisations in England and Wales; when taken in isolation, these statistics may not provide the context required by users to enable them to understand the national and local picture of domestic abuse.
Data relating to the criminal justice system and specialist domestic abuse services only refer to cases of domestic abuse that become visible to the police and services; cases that enter the criminal justice system may drop out at any stage of the process.
Recent improvements to the Domestic abuse in England and Wales data
The statistics presented in the 2018 publication expand on those included in previous releases, through user feedback from domestic abuse organisations, police force staff and police and crime commissioners. This year, new data sources have been included that provide information on domestic abuse-related stalking and harassment, domestic violence remedy orders, and coercive and controlling behaviour. More detailed data on the services available to the victims of domestic abuse has also been provided.
Future developmental phases will continue to fill gaps in domestic abuse data by looking at new data sources to create a more comprehensive resource for users.
Notes on: Quality summary
- Further information on the Open The Door campaign can be found on the Cheshire Police website
The aim of this publication is to bring together data from several different organisations in England and Wales on domestic abuse to enable appropriate action to be taken to improve victims’ experiences of the criminal justice process and to encourage more victims to come forward to report abuse, knowing that there is appropriate support available for them. The data also provides a clearer understanding of the criminal justice system’s response to perpetrators of domestic abuse.
Data on Domestic abuse in England and Wales receive significant interest from a range of users including elected national and local representatives (such as MPs, Police and Crime Commissioners and local councillors), Home Office and other government agencies, police forces, those delivering support or services to victims of crime, lobby groups, journalists, academic researchers, teachers and students.
The data included in the report and data tool is aimed primarily at agencies that work with domestic abuse victims such as the police and the voluntary sector, so that responses to victims and perpetrators of domestic abuse can be improved.
See the “Uses and users of the domestic abuse in England and Wales data” section for more information.
Accuracy and reliability
The publication includes data from several data sources, the majority of which are based on administrative records.
More information on the accuracy of each of the data sources is given in the “Main data sources and their accuracy” section.
For more detail on the accuracy and reliability of the data from the Crime Survey for England and Wales see the Crime in England and Wales QMI.
Coherence and comparability
The data included in the publication come from several sources and direct comparisons cannot be made between figures. This is because the different sources of data do not always relate to the same cases as often different timescales and reference periods have been used during collection. They also do not count the same things; for example, some record the number of victims or defendants, whilst others record the number of incidents or offences that occurred.
Comparisons of the same data sources over time can be made, for example, comparison of domestic abuse-related crimes recorded by the police. However, such data can be affected by changes in levels of reporting to the police or police recording practices. For example, comparisons of the data over time need to take account of the introduction of new legislation and changes to the Home Office Counting Rules, which will subsequently impact on the volume of cases passing through the criminal justice system.
Concepts and definitions
Domestic abuse is not limited to physical violence. It can include repeated patterns of abusive behaviour to maintain power and control in a relationship. The current cross-government definition1 of domestic violence and abuse recognises this and defines domestic abuse as:
“Any incident or pattern of incidents of controlling2 , coercive3 , threatening behaviour, violence or abuse between those aged 16 or over who are, or have been, intimate partners or family members regardless of gender or sexuality. It can encompass, but is not limited to, the following types of abuse:
With the exception of coercive and controlling behaviour, which was introduced as a criminal offence on 29 December 2015, other acts of domestic abuse fall under generic offence categories in police recorded crime and criminal justice data, such as assault with injury.
For detailed definitions of other terms referred to in the publication see Annex 2: Glossary of the “Domestic abuse in England and Wales, year ending March 2018” publication.
Data on domestic abuse is available at national level for England and Wales. Some datasets are also available at police force area level.

Timeliness and punctuality
Domestic abuse in England and Wales is published on an annual basis. The data included in the publication is the latest available at the time of publishing. Information on the time period of each of the data sources included in the publication is given in Table 2.
Notes on: Quality characteristics of the Domestic abuse in England and Wales data
The Crown Prosecution Service applies the government definition to all victims and perpetrators of domestic abuse irrespective of age.
Controlling behaviour is a range of acts designed to make a person subordinate and/or dependent by isolating them from sources of support, exploiting their resources and capacities for personal gain, depriving them of the means needed for independence, resistance and escape and regulating their everyday behaviour.
Coercive behaviour is an act or a pattern of acts of assault, threats, humiliation and intimidation or other abuse that is used to harm, punish, or frighten their victim.
Main data sources and their accuracy
Statistics on domestic abuse are produced separately by several different organisations in England and Wales. When taken in isolation, these statistics may not provide the context required by users to enable them to understand the national and local picture of domestic abuse. This report brings together the following sources.
|Data supplier||Data||Time period||Geography||Important points|
|Year ending March 2018||England|
|Analysis presented in the report covers adults aged 16 to 59 years who are resident in households in England and Wales and who completed the self-completion section of CSEW on domestic abuse, sexual assault and stalking.|
|Home Office||Police Incident|
|Year ending March 2018||England|
|Data on crimes recorded by the police that were flagged as domestic abuse-related have been collected since April 2015. This includes data on domestic abuse-related stalking and harassment and coercive and controlling behaviour, which became an offence on 29 December 2015.|
Incidents refer to domestic abuse-related incidents that did not get recorded as a crime.
|Home Office||Police Outcomes|
|Year ending March 2018||England|
|Collected through the Home Office Data Hub, a record-level crime system, which police forces have been progressively switching over to.|
26 police forces provided adequate domestic abuse outcomes data for the year ending March 2018.
|Home Office||Home Office Homicide|
|Year ending March 2015 to year ending March 2017||England|
|The Home Office Homicide Index is continually updated with revised information from the police as investigations continue and as cases are heard by the courts; the version used for analysis does not accept updates after it is “frozen” to ensure the data do not change during the analysis period.|
Analysis combines data for a three -year period due to year-to-year variability in the volume of homicides recorded.
|Crown Prosecution Service (CPS)||Referrals, prosecutions and convictions||Year ending March 2018||England and Wales||A domestic abuse flag may be applied at the beginning of a case, or applied later in the prosecution process if a domestic abuse relationship becomes apparent.|
Due to a time lag between each stage of the criminal justice process, data for referrals, prosecutions and convictions may not refer to the same cohort of cases.
CPS data include adult and child defendant and victim data and therefore do not strictly align with the government definition of domestic abuse, which only applies to those cases where both the victim and perpetrator are aged 16 years or over.
|Crown Prosecution Service (CPS)||Coercive and controlling behaviour data||Year ending March 2018||England and Wales||Data relate to the number of offences of coercive and controlling behaviour recorded in magistrates' courts, in which a prosecution commenced, as recorded on the CPS case management system.|

How we analyse and quality assure the data
Several methods are used to ensure the quality of the Crime Survey for England and Wales data collection operation by both Kantar Public, the survey contractor, and Office for National Statistics (ONS). Kantar Public has robust quality management systems in place, which are formally accredited, and endorsed and supported at a corporate level; more information can be found in the annual technical reports.
ONS also has quality management systems in place to further quality assure the data when it comes to us for final preparation and publication. Any errors identified through these checks are returned to Kantar Public for validation or correction, checks are also carried out within the team throughout the data production process before final publication.
Regarding police recorded crime, prior to submitting data to us the Home Office Police Data Collection Section (PDCS) and Home Office Statistics Unit carry out internal quality assurance of the recorded crime data. Any anomalies or errors identified through these checks result in a report being returned to the relevant force for validation or correction. Prior to publication of any crime statistics, verification checks are also carried out, asking individual forces for confirmation that the data accords with that held on their own systems. For more information, see Chapter 3 of the User guide.
All other data included in the publication are quality assured by the individual data suppliers and further checks are carried out by our team on receipt of the data. Any discrepancies are queried with the supplier for validation.
How we disseminate the data
Domestic abuse in England and Wales is published annually. The publication includes a statistical bulletin describing the main patterns and trends in the data, accompanied by data tables. A data tool is also provided to allow users to explore data for police force areas in more detail.
How we review the data
The publication on Domestic abuse in England and Wales, year ending March 2018 has been produced in response to a recommendation made by HMICFRS in their 2015 progress report on the police response to domestic abuse. It said that organisations should work together to “develop a dataset relating to domestic abuse, which will enable more thorough analysis of how domestic abuse is dealt with in a force area.”
This annual publication forms phase three of a wider project on improving domestic abuse statistics in England and Wales. User feedback has been obtained during the development of phase three through discussions with domestic abuse organisations, police force staff and police and crime commissioners. We are seeking additional feedback on phase three of the project and discussions will commence around what data should be considered for phase four, currently expected to be published in late 2019. We expect that phase four will include all the data presented in phase three updated for the latest year and will continue to fill gaps in domestic abuse data by looking at new data sources and expanding detail on data such as demographics of victims.Back to table of contents
