<P>Abstract copyright UK Data Service and data collection copyright owner.</P><p>Modern slavery is a term that includes any form of human trafficking, slavery, servitude or forced labour, as set out in the Modern Slavery Act 2015. Potential victims of modern slavery in the UK that come to the attention of authorised ‘First Responder’ organisations are referred to the National Referral Mechanism (NRM). </p> <p>Adults (aged 18 or above) must consent to being referred to the NRM, whilst children under the age of 18 need not consent to being referred. As specified in section 52 of the Modern Slavery Act 2015, public authorities in England and Wales have a statutory duty to notify the Home Office when they come across potential victims of modern slavery ('Duty to Notify' (DtN)). This duty is discharged by either referring a child or consenting adult potential victim into the NRM, or by notifying the Home Office via the DtN process if an adult victim does not consent to enter the NRM.</p> <p>The Home Office publishes quarterly statistical bulletins and aggregated data breakdowns on the <a href="https://www.gov.uk/government/collections/national-referral-mechanism-statistics" target="_blank"> National Referral Mechanism</a> webpage on the GOV.UK website regarding the number of potential victims referred each quarter. To allow stakeholders and first responders more flexibility in analysing this data for their own strategic and operational planning, the disaggregated, pseudonymised dataset used to create the aggregated published data is also available from the UK Data Service as 'safeguarded' data. (The UKDS data are available in SPSS, Stata, tab-delimited text and CSV formats.) </p> <p><span style="font-weight: bold;">Latest edition information</span></p> <p>For the 19th edition (December <span>2025), a new version of the data file including up to Quarter 3 2025 cases replaced the previous one. Two variables, '</span>recon_DQ' (Reconsideration - Disqualification decisions (DQ)) and 'recon_DQ_received_YQ' (Reconsideration - Disqualification decisions (DQ) Year/Quarter) have been removed, and the Data Notes documentation file was also updated. </p><B>Main Topics</B>:<BR><p>The UKDS version of the NRM dataset includes:</p> <ul> <li>Referral Year/Quarter</li><li>Current decision status</li><li>Gender</li><li>Age group at exploitation (Adult/Child)</li><li><span>Age at referral</span></li><li>Age group at referral (Adult/Child)</li><li>Nationality (including dual-nationalities)</li><li>Exploitation type reported</li><li>County lines involvement (Yes/No)</li><li>Location of exploitation (UK/overseas)</li><li>UK Country<br> </li><li>Police force sent NRM for investigation</li><li>First responder (Local Authority, Police force, NGO, Government agency)</li><li>Reasonable Grounds (RG) decision outcome</li><li>Reason for negative RG decision</li><li>RG decision Year/Quarter</li><li>Difference in days between the referral date and date of RG decision</li><li>Age of case: number of days between the referral date and the date of the end of the most recently published quarter</li><li>Conclusive grounds (CG) decision outcome</li><li>Reason for negative CG decision</li><li>CG decision Year/Quarter</li><li>Difference in days between the referral date and date of CG decision</li><li>Overseas country (1-10)</li><li>UK County (1-10)</li><li>Competent authority</li><li>Disqualification (DQ) outcome</li><li>Disqualification (DQ) Year/Quarter</li><li>Disqualification (DQ) reason</li><li>Reconsideration - Reasonable grounds (RG)</li><li>Reconsideration - Reasonable grounds (RG) Year/Quarter</li><li>Reconsideration - Conclusive grounds (CG)</li><li>Reconsideration - Conclusive grounds (CG) Year/Quarter</li><li>Date withdrawn</li><li>Withdrawn or suspended</li></ul>
