Data relate to year ending June 2017 and all comparisons are with year ending June 2016, unless indicated otherwise.

This section covers statistics on individuals held in immigration detention (solely under Immigration Act powers) for a variety of reasons, including reasons within and outside the control of the Home Office. These figures show only those detained in immigration removal centres (IRCs), short term holding facilities (STHF) and pre departure accommodation (PDA). In addition, figures in this section relate to returns of people, by the Home Office, who do not have any legal right to stay in the UK.

1. Key facts

The number of people entering detention in year ending June 2017 decreased by 12% to 27,819 from 31,593 in the previous year. Over the same period there was a 13% decrease in those people leaving detention (from 32,067 to 27,862).

As at the end of June 2017, 2,994 (of which, 2 were children) people were in detention, 4% more than the number recorded at the end of June 2016 (2,878). In addition, as at 26 June 2017, there were 360 detainees held in prison establishments in England and Wales solely under immigration powers as set out in the Immigration Act 1971 or UK Borders Act 2007.

The number of children entering detention in year ending June 2017 was 48, 65% lower than the previous year (137). This was a 96% fall compared with the beginning of the data series in 2009 (1,119).

The proportion of detainees being returned or voluntarily departing from the UK on leaving detention increased from 44% in year ending June 2016 to 48% in year ending June 2017.

The total number of enforced returns from the UK, including those not directly from detention, decreased by 3% to 12,542 in the year ending June 2017 compared with 12,944 in the previous year. This includes 10,642 enforced removals and 1,900 other returns from detention. In the same period, there were 22,822 voluntary returns (excluding returns from detention).

Of the 12,542 enforced returns in year ending June 2017, there were 1,970 enforced removals of people who had previously sought asylum, down 30% from the previous year (2,813).

In the year ending June 2017, provisional data show that 6,071 Foreign National Offenders (FNOs) were returned compared to 6,064 in the previous year (see Returns table rt_06q). This is the one of the highest number since the series began in 2009 and reflects increasing use of other forms of FNO returns, including those where an offence was committed outside the UK.

(1) Total enforced returns covers 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. This new grouping has been created to reflect the likely level of enforcement activity that led to these returns.
(2) Enforced removals include enforced removals from detention and non-detained enforced removals.
(3) Other returns from detention relate to those returns occurring either from detention or up to two days after leaving detention AND where it had been established that a person has breached UK immigration laws and/or have no valid leave to remain in the UK.

The largest number of passengers refused entry at port and subsequently departed were United States (US) nationals (1,600; 9% of the total), of which 1,031 (64%) were returned home. US citizens (and Brazilian nationals, the third largest number) who are not coming to the UK for work or for 6 months or more do not need to apply for, and be issued with, a visa prior to arrival; therefore, the first time that they can be refused entry will be on arrival in the UK.

5. Enforced returns of EU nationals

EU nationals may be returned for not exercising, or abusing, Treaty rights or for deportation on public policy grounds (such as criminality).

There were 20% more enforced returns (5,301) of EU nationals in the year ending June 2017 compared with the previous 12 months (4,424), and 26% more EU nationals were refused entry at port and who subsequently departed (2,726 compared to 2,158).
