1. Introduction

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 NRM.

Authorised ‘First Responder’ organisations include local authorities, specified non-governmental organisations (NGOs), police forces and specified government agencies. 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. Adults who were exploited as children can also be 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. 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.

When referred to the NRM, the SCA within the Home Office makes a ‘reasonable grounds’ decision on whether an individual could be a victim of modern slavery.

Adults given a positive reasonable grounds decision can have access to support (including accommodation, subsistence, legal aid and counselling) pending a ‘conclusive grounds’ decision on their case. Local authorities support children.

Currently, adults with a positive conclusive grounds decision are entitled to at least a further 45 days of support, whilst those with a negative decision receive nine days of ‘move on’ support as the individual exits the service. See further information regarding the NRM process.

1.1 User feedback survey

The user feedback survey on NRM statistics ran for six weeks and closed on 1 May 2020. We received 50 responses from a range of stakeholders and would like the thank those who responded. We are continuing to examine options for the release of further data in future bulletins.

Please email NRMStatistics@homeoffice.gov.uk if you have any further comments or questions regarding these statistics.

Correction

An error in data processing was identified that resulted in the incorrect classification of some potential victims, primarily child potential victims, as age at exploitation ‘Not recorded or unknown’. This has been corrected in the updated bulletin/data tables using an updated cut of data taken 7 December 2021. This error is related to data processing for the statistical bulletins, and did not affect the classification of referrals within the NRM system itself.

2. National Referral Mechanism (referrals)

2.1 Number of referrals by age group

In the second quarter of 2021, the NRM received 3,127 referrals of potential victims of modern slavery. This represents a 6% increase in referrals compared to the preceding quarter (2,942) and a 42% increase from quarter 2 in 2020 (2,203). This quarter saw the second-highest number of quarterly referrals since the NRM began and the highest number of referrals since the beginning of the COVID-19 pandemic.

Of all referrals this quarter, 50% (1,560) were for potential victims who claimed exploitation as adults (compared to 49% in the preceding quarter), whilst 44% (1,361) claimed exploitation as children (Figure 2). The age group at exploitation was unknown in 7% of cases (206).

Notes(s): Excludes data pre-2014 due to data reliability. Excludes referrals where the age group at exploitation is unknown.

2.2 Location of exploitation

Overall, 61% (1,894) of potential victims claimed exploitation in the UK only, compared to 64% in the last quarter, whilst 28% (880) claimed exploitation overseas only (data table 2; Figure 3). Following a substantial decrease in quarter 1, referrals for those claiming exploitation overseas have increased sharply again this quarter, which is likely to be due to increased travel into the UK as COVID-19 travel restrictions have eased.

Notes(s): Excludes data pre-2014 due to data reliability.

2.3 Referrals by gender and exploitation type

Overall, of the 3,127 potential victims referred in this quarter, 77% (2,411) were male and 23% (714) were female. These proportions are similar to recent quarters, although male potential victims have formed an increasing proportion of NRM referrals over the years.

For adult potential victims, 75% (1,163) were male and 25% (397) were female; whilst for child potential victims, 80% (1,083) were male and 20% (276) were female.

Notes(s): Data for unclassified exploitation can be provided in a free-text field by first responders. For statistical reporting, this field is grouped as ‘Not specified or unknown’.

As in previous quarters, overall potential victims were most commonly referred for criminal exploitation only, which accounted for 34% (1,070) of all referrals. An additional 15% (454) of referrals stated potential victims had been referred for criminal exploitation and other exploitation types.

For adult potential victims, labour exploitation was most commonly reported (32%; 501), whereas child potential victims were most often referred for criminal exploitation (49%; 664). See further information on types of exploitation.

For those exploited as children, an increase in the identification of ‘county lines’ cases has partially driven the increase in referrals within the criminal exploitation category. County lines is a term used to describe drug gangs in large cities expanding their reach to small towns. Often, the gangs exploit vulnerable individuals to transport substances, and mobile phone ‘lines’ are used to communicate drug orders. See further information on county lines.

In quarter 2, 444 county lines referrals were flagged, accounting for 14% of all referrals received in the quarter (data table 27). The majority (76%; 338) of these referrals were for male children.

Notes(s): County lines referrals were classified as a sub-type of labour exploitation prior to quarter 2019. Since January 2020, a ‘flag’ within the NRM digital casework system identifies county lines referrals.

2.4 Referrals by nationality

The most common nationality referred was UK nationals, which accounted for 33% (1,026) of all potential victims (compared to 36% in the previous quarter). The second most commonly referred nationality was Albanian (17%; 545) and the third was Vietnamese (10%; 324). A large proportion (74%; 761) of UK nationals were child potential victims, whilst for Albanian nationals, most (83%; 450) were adult potential victims. For Vietnamese nationals, 58% (187) were adults and 27% (89) were child potential victims (Figure 6). There was a notable increase in referrals for both Vietnamese and Sudanese nationals this quarter (81% and 38% respectively).

Please note, a change to data recording from 1 October 2019 means that NRM data reflects the dual nationality of potential victims in separate categories. To see total counts of a particular nationality, please refer to the data tables. A potential victim’s nationality is based on information provided by the first responder upon referral; however case workers may update this as further information is gathered.

Notes(s): Excludes potential victims with an unknown age at exploitation. There are separate categories for dual-nationals.

2.5 Referrals by location of crime investigation

Upon receiving an NRM referral, the SCA determines the responsible geographic police force for investigation, based on the information provided on the referral form, and transfers the referral. Transfer between police forces can take place as they receive further information, which is reflected in the statistics. Previously, British Transport Police referrals were classed under England, but are now separate in the data tables.

As in previous quarters, most (91%; 2,843) of the NRM referrals were sent to police forces in England, with 4% (117) to Police Scotland, 3% (104) to Welsh police forces and 1% (42) to the Police Service of Northern Ireland (data table 2).

2.6 First responders

In quarter 2 2021, 34% (1,063) of the referrals came from government agencies, compared to 28% in the previous quarter. Of these referrals, 33% (347) came from Home Office Immigration Enforcement, compared to 28% in the previous quarter, whilst a large proportion came from UK Visas and Immigration (64%; 682) (Figure 7 and data table 9). Police forces accounted for 33% (1,018) of NRM referrals in quarter 2 (compared to 36% in the previous quarter). NGO and third-sector organisations accounted for 8% (258) of referrals. Local authorities accounted for 25% (787) of referrals, mostly for child potential victims.

3. National Referral Mechanism (decisions)

3.1 Reasonable grounds decisions

The SCA issued 3,053 reasonable grounds decisions in quarter 2 2021. Of these decisions, 90% (2,741) were positive and 10% (312) were negative. The proportion of positive reasonable grounds decisions was 87% for adult and 93% for child potential victims (data table 28). The number of reasonable grounds decisions made per quarter tends to correspond to the number of referrals received, though it is important to note that the SCA could have made reasonable grounds decisions on referrals received in previous quarters.The proportion of positive decisions has remained relatively similar in recent years, with around nine out of every ten referrals receiving a positive decision.

Notes(s): Based on the quarter in which the SCA issued their decision.

3.2 Conclusive grounds decisions

In quarter 2, the SCA issued 492 conclusive grounds decisions, compared to 395 in the previous quarter and 832 in the same quarter of the previous year. Of the decisions issued this quarter, 89% (437) were positive and 11% (55) were negative. The proportion of positive conclusive grounds decisions was 82% for adult and 97% for child potential victims (data table 29).The decrease in the number of decisions made in 2021 so far is due to resource pressures within the SCA and a subsequent reduction in capacity as the SCA onboards and trains many new staff.

Notes(s): Based on the quarter in which the SCA issued their decision.

The average (median) time taken from referral to conclusive grounds decisions made in this quarter was 436 days, compared to 412 days in the previous quarter. It is important to note that the decision-making times presented here are for cases that received a conclusive grounds decision from the SCA in this period and do not reflect the waiting time of all cases within the system. Some cases that receive decisions in this period may have taken longer to reach a decision than those in previous quarters (data table 30).

3.3 Duty to Notify

Since 1 November 2015, specific public authorities in England and Wales must notify the Home Office via the DtN process of suspected adult victims of modern slavery that do not consent to enter the NRM. During this process, first responders do not collect the potential victim’s personal details.

In quarter 2 2021, the Home Office received 910 reports of adult potential victims via the DtN process (Figure 10), compared to 718 in the preceding quarter.This is the highest quarterly number of DtN reports received. Of these:

• the most commonly referred nationalities were Albanian (119; 13%), Vietnamese (118; 13%) and UK (100; 11%) (data table 32)

• the most commonly referred exploitation types were labour (356; 39%), criminal (148; 16%) and sexual (137; 15%) (data table 33)

• in terms of first responders, most DtN reports were submitted by Home Office - UK Visas and Immigration UKVI (394; 43%), Home Office - UK Border Force UKBF (74; 8%) and Metropolitan Police Service (54; 6%)

Notes(s): Potential victims may be reported via DtN and subsequently also referred to the NRM at a later point in time, so these figures should not be combined due to potential double counting.

4. Further information

Quality information

All percentages are rounded to the nearest whole percentage point.

It is important to note that the statistics presented in this publication relate to the number of potential victims of modern slavery referred to the NRM or via the DtN process.

These statistics are based on the situation as at 7 December 2021 when an extract was taken from the live management information system. The figures may differ from previous or future reports as new information comes to light and cases update accordingly.

NRM statistics were previously published by the National Crime Agency (NCA) prior to transfer of NRM decision-making responsibilities to the SCA in April 2019 as part of the NRM Reform Programme. Publications prior to July 2019 can be accessed via the NCA website. With this transfer of responsibility, these data are now designated as official statistics and produced in line with the Code of Practice for Statistics.

Data tables for further analysis can be found online alongside this bulletin.

This statistical bulletin is produced to the highest professional standards and is free from political interference. It has been produced by statisticians working in the Home Office Analysis & Insight Directorate under the Home Office’s Statement of compliance with the Code of Practice for Official Statistics, which covers Home Office policy on revisions and other matters. The Chief Statistician, as Head of Profession, reports to the National Statistician regarding all professional statistical matters and oversees all Home Office National Statistics products regarding the Code, being responsible for their timing, content and methodology.

Changes to recording of exploitation types

Prior to 1 October 2019, potential victims of modern slavery were recorded as having a single primary exploitation type, grouped into five distinct categories: labour, sexual, domestic servitude, organ harvesting or unknown exploitation. Following changes to the way NRM data are collected, recording of exploitation types has changed to give a better picture of the exploitation experienced by potential victims. As a result, for referrals received from 1 October 2019, criminal exploitation is separate to labour exploitation. In addition, potential victims can also be recorded as experiencing multiple exploitation types, so apply caution when comparing exploitation type statistics from quarter 4 2019 with previous quarters, as the primary exploitation type is unknown. Furthermore, ‘Unknown exploitation’ is no longer a distinct category on the online form that first responders use when submitting a referral; instead, they can provide information for unclassified exploitation in a free-text box field. For statistical reporting, this field is grouped as ‘Not specified or unknown’.

Criteria applied to identify the relevant police force:

Police force data provided in associated reference tables are based on the location of the police force that received the NRM referral. Each referral is screened against the criteria below to identify the responsible geographic police force. Once identified, the referral is transferred for action to the relevant Force Intelligence Bureau or stipulated point of receipt within the force. Sometimes, further information is received and processed regarding a referral, which means it will be sent to a different police force. This will be reflected in the updated statistics. Criteria applied to identify the relevant police force are:

• the force has acted as first responder, or the referral indicates that the force is already involved in the recording/investigation of the potential modern slavery human trafficking offences

• the potential victim has been exploited within the force area

• the potential victim has been exploited abroad, or at an unknown location and the victim’s address at time of referral is within the force area

• the potential victim has been exploited abroad or at an unknown location and they have presented to another first responder within the force area
