We publish statistics taken from the Crime Survey for England and Wales (CSEW) and crimes recorded by the police. Our statistics cover England and Wales.
We do not hold information on perpetrators of crime. Statistics on offenders are primarily held by the Ministry of Justice (MoJ), who may be better placed to answer your query around this data. Their email address is statistics.enquiries@justice.gsi.gov.uk
Our Sexual Offending: victimisation and the path through the criminal justice system publication provides information on convictions for sexual offences. In particular the Sexual offending: Ministry of Justice Appendix tables may be of interest.
