Breakdowns

What this measures

The number of people who left immigration detention in each quarter, for any reason — bailed, returned from the UK, granted leave, or other.

What this doesn’t measure

Distinct individuals across quarters (a person detained and released twice is counted twice), people entering detention, or those still detained.

Important caveat

Entries to detention count occurrences, not individuals: a person detained twice in a quarter is counted twice. Nationality is as recorded by the Home Office. People held in prisons under immigration powers are included only from 2017. Data from 2026 Q1 onwards is provisional.

Revision history

No period of this series has been revised since it was first ingested here. Revisions are recorded automatically when a later release publishes a different figure for the same period.
