Thank you for your enquiry. The answers to these questions are quite complex as data are available from numerous sources and do not exactly match what you have requested. We have explained below what data are available and where you can find more information.
In order to estimate a sex ratio you need data on perpetrators. National Statistics on perpetrators are primarily held by the Ministry of Justice, who publish an annual report on Criminal Justice System Statistics. In their latest report, covering the 2015 calendar year, the Ministry of Justice published: Experimental statistics – proceedings and outcomes by Home Office offence code, where convictions are broken down by sex. In the calendar year 2015, there were 1,297 convictions for rape and attempted rape, from which 99.3% were male, 0.5% were female and 0.2% were unknown. For more information on this data please contact the Ministry of Justice at statistics.enquiries@justice.gsi.gov.uk.
The Crown Prosecution Service also publishes data on rape prosecutions and convictions in their annual publication on Violence against Women and Girls (inclusive of data on men and boys), covering the financial year 2015-2016. However, only prosecutions are broken down by sex in this dataset, not convictions. You may wish to contact the Crown Prosecution Service for further information, at enquiries@cps.gsi.gov.uk.
We do not have information on how many perpetrators convicted of domestic abuse were male. Domestic abuse (with the exception of coercive and controlling behaviour) is not a specific offence in law, but is prosecuted under other offence categories (for example, assault with injury or harassment). As a result, the Ministry of Justice criminal court data do not include domestic abuse related offences as it is currently not possible to identify prosecutions or convictions that involve such offences.
The Crown Prosecution Service applies a flag to identify domestic abuse related cases on their Case Management System. Domestic abuse related prosecutions and convictions figures from the Crown Prosecution Service are included in our report on Domestic Abuse in England and Wales, year ending March 2016, published in December 2016. In the publication’s Appendix tables, Table 14 contains number of convictions and unsuccessful prosecutions for domestic abuse related offences from the year ending March 2010 to the year ending March 2016, and Table 15 contains the sex of defendants and victims in domestic abuse related prosecutions covering the same time period. In the year 2013-14, 93.1% of defendants were male; in the year 2014-15, 92.4% of defendants were male; and in the year 2015-16, 92.0% of defendants were male. However, as with rape, convictions of domestic abuse related offences are not broken down by sex in this dataset.
