Freedom of Information Request   
You requested the following information from the Ministry of Justice (MoJ):
For future discussions and potential programme-making we would like to investigate reports that 60% of males in prison convicted of rape are Muslims. Please can you give us the proper stats for these?
Your request has been handled under the Freedom of Information Act 2000 (FOIA) and I can confirm that the MoJ holds information that you have asked for and it is provided below.
Sexual offences are traumatising crimes which ruin lives. Tough new sentences are available for those who commit these dreadful crimes - and under this Government sex offenders are more likely to go to prison and for longer. We recently introduced a new mandatory life sentence for people convicted of a second very serious sexual or violent crime and introduced tough new Extended Determinate Sentence which will ensure dangerous offenders spend long periods in prison and are supervised for long periods after their release.
As at 31 March 2014, the latest point in time for which data is available for public use, the male prison population in England and Wales for all offenders serving immediate custodial sentence for rape was 5,682. Of this, there were 676 offenders who self-declared their religion as Muslim (12% of the total).
Please note that the figures given relate to offenders for whom these offences were the principal offences for which they were sentenced to immediate custody. When a defendant has been found guilty of two or more offences it is the offence for which the heaviest penalty is imposed. Where the same disposal is imposed for two or more offences, the offence selected is the offence for which the statutory maximum penalty is the most severe. As such offenders convicted of murder and rape at the same time are excluded from the figures. Also the data relates to prisoners' current self-declared religion, not any previously declared religion on reception into prison as prisoners are under no obligation to declare their religion.
These figures have been drawn from administrative IT systems which, as with any large scale recording system, are subject to possible errors with data entry and processing.
