This is not the latest release. View latest release.

Data relate to the year ending June 2018 and all comparisons are with the year ending June 2017, unless indicated otherwise.

This section contains data on:

• individuals held in immigration detention (solely under Immigration Act powers)
• returns of people, by the Home Office, who do not have any legal right to stay in the UK

1. Key facts

In the year ending June 2018, 26,215 individuals entered the detention estate (down 6% compared with the previous year) and 27,481 left the detention estate (down 1%).

At the end of June 2018, there were 1,905 persons held in the detention estate (excluding HM Prisons), a fall of 36% compared with the same date 12 months earlier. Additionally, 321 individuals were held in immigration detention in HM Prisons.

The total number of enforced returns from the UK, decreased by 13% to 10,892 in the year ending June 2018 compared with 12,509 in the previous year.

Provisional data show that 5,724 Foreign National Offenders (FNOs) were returned in the year ending June 2018, down 8% compared to 6,238 in the previous year; of these:

• just over two thirds (68%) were EU nationals (3,905)
• just under one third (32%) were non-EU nationals (1,819)

2. Immigration detention

2.1 Detention

From July 2017, data on detention of immigration detainees in prisons are included in the immigration detention figures. Previously, individuals who were detained in prison would have been recorded in the data upon entering the detention estate through an immigration removal centre (IRC), short-term holding facility (STHF) or pre-departure accommodation (PDA); now they are recorded upon entering immigration detention within prison. Data from Q3 2017 onwards are therefore, not directly comparable with earlier data. Further details of these changes can be found in the user guide.

In the year ending June 2018, 26,215 people entered the detention estate. This was down 6% on the previous year, and represents a fall for the third consecutive year.

Chart note:

1. Prior to July 2017, those entering detention in prisons would not be counted in the entering figures until they entered the detention estate. These cases are now included when entering immigration detention in prison. This means those entering through prisons will be recorded earlier than previously, and those who were not moved from the prison to the detention estate would not previously have been counted.

As at the end of June 2018, there were 1,905 people in the detention estate (excluding prisons). This was 36% lower than the same time the previous year. In addition, 321 immigration detainees were held in HM Prisons.

At the end of June 2018, there were 325 EU nationals, and 1,901 non-EU nationals in detention (including prisons).

Table rt 01 q (Returns tables, volume 1)

Table notes:

1. ‘Enforced returns’ cover enforced removals from detention, non-detained enforced removals and other returns from detention where the Home Office will have been required to facilitate or monitor the return.
2. ‘Voluntary returns’ include a variety of departures, including assisted voluntary returns, controlled returns and other verified returns (for example, through data matching). These are subject to significant upward revision as matching checks are made on travellers after departure. Comparisons with the previous 12 months for voluntary returns have not been included as data are not comparable over time.
