The Ministry of Justice has published information on prosecutions, up to December 2019, for offences under the Modern Slavery Act 2015. These are available in the ‘Outcomes by Offence’ data tool, here:
Data held centrally by MoJ does not identify the age of the victim unless this is specified by the relevant legislation. Therefore, centrally held information cannot separately identify the number of modern slavery prosecutions that involved child victims. The information may be held on court record; however, identification of the victim’s age would require access to court records and transcripts, which would incur disproportionate cost.
