What this measures

The number of people held in immigration detention on the last day of the quarter, split by nationality. This is a stock, not a flow.

What this doesn’t measure

Entries to or exits from detention during the quarter, or people held in prisons under immigration powers before 2017.

Important caveat

This is a snapshot count of people in immigration detention on the last day of the quarter, not a total over the quarter. Since the March 2023 snapshot the Home Office publishes length of detention as "Not available" for everyone in detention, so the length breakdown carries a single bucket for recent periods. 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.
