Over recent years there has been little change in the prevalence of domestic abuse estimated by the crime survey, while the number of cases recorded by the police has increased.
However, the majority of cases do not come to the attention of the police, and many of those that do, do not result in a conviction for the perpetrator of the abuse.
Referrals can be made by a number of different agencies (or by the victim directly) so provision of these services may not be reliant on the reporting of domestic abuse to the police.
It also shows that the majority of victims will not report the abuse they have experienced to the police.
Therefore, while the CSEW provides the best available estimate of trends in the prevalence of domestic abuse, they may not match trends in administrative data sources.
Cases may also drop out at any stage of the process.
The different datasets included in this report do not relate to the same cases given the different timescales and reference periods used to collect the data.
This in part reflects police forces improving their identification and recording of domestic abuse incidents as crimes and an increased willingness by victims to come forward.
The police made 225,714 arrests for domestic abuse-related offences (in the 39 police forces that could supply adequate data).Domestic abuse is often a hidden crime that is not reported to the police.Therefore, data held by the police can only provide a partial picture of the actual level of domestic abuse experienced.Similarly, data from the Crime Survey for England and Wales (CSEW) should not be viewed in isolation.The estimates from the survey show a higher level of domestic abuse, in terms of the number of victims, than other data sources.In the year ending March 2018, 76% of prosecutions resulted in a conviction.
